Welcome to the seventh issue of Cultivate Interactive.
Historians of the future will look back upon the First Information Age of the 20th. and 21st.Centuries, and apart from arguing over the nomenclature, they will also be amazed: not only by the difficulties it had in reaching common standards of operation but also by the period's attempts to gather information from so many and seemingly disparate sources. If they ever alight upon this issue 7 of Cultivate Interactive, I feel sure they will be impressed by the effort and energy of the professionals in the DIGICULT projects and elsewhere in achieving their goals.
Those same historians, on reading the article on the ARTISTE Project, would begin to appreciate the enormous wealth of imagery already available to users, but users with no organised means of searching for what they needed. However the ARTISTE Project had produced a means of searching quickly through tens of thousands of images distributed across 4 databases each with a different metadata schema. This enormous wealth of pre-digital collections of multimedia posed the Age with another type of problem: preservation. At the turn of the 20th. Century, broadcasting organisations were confronted with large quantities of culturally vital material endangered either by damage beyond repair through ageing or rendered inaccessible by the rapid redundancy of the format in which they had initially been recorded. The PRESTO Project article will give a clear exposition of the preservation problems and the cost-effective solutions PRESTO was producing. (Additionally the issue carries a report on the Multimedia Archive Preservation Workshop held in London in May 2002).
Not that the professionals of the DIGICULT Programme were just concerned with collation and preservation of modern media, as the Kalliope article can testify. This project set about creating an on-line union catalogue of the manuscripts and letters of not just the famous but ordinary unremarked people of by-gone ages. Moreover, it was the less well-known who formed part of the raison d'être of the COINE Project which placed emphasis upon the inclusion of material from communities relatively unversed in the technology of the Internet, but which nonetheless had something valuable to say. By making access to distributed material much simpler for ordinary users and by providing them with a platform for their own writings, COINE was seeking to turn passive users into active contributors. Achieving a better understanding of those users was a key issue for representatives of various cultural content programmes world-wide when they gathered in Washington D.C. to discuss movement Towards a digital Cultural Content Forum. Globalisation was well underway by then, but this meeting, as the article stated, "emphasised some of the very real differences in approach across the jurisdictions represented, ..".
Those historians of the future will, of course, have ample proof of the major headache that achieving common standards represented. However, another article in Cultivate Interactive 7 from the COVAX Project demonstrated the progress made in moving libraries, museums and archives into a European Information Environment through the adoption of XML-based networking of their collections. The article on PULMAN described the Project's work on common technical standards and other support for public libraries, museums and archives.
However, the historians of the future ought to be interested in an article Challenges for a Semantic Web which stood back for a while from the competing pressures of different technological approaches in order to consider the existing strategies for a semantic web and to examine the benefits of a different method. In his article Kim Veltman pointed out some possible dangers, even one spine-chilling one, and reminded his readers that, once again, we should not lose sight of the less well-known communities on a sub-national level and the enormous cultural diversity they still represented in the 21st.Century, something that needed to be properly reflected in the evolving semantic web.
An article from the TOURBOT Project might have appeared, at first, to resolve a question posed by the introspective observers of the 1950's who predicted that robots might assume a dominant role in our lives. Indeed there was Tourbot conducting visitors around exhibitions. But those observers had not reckoned with the Internet, nor therefore Tourbot's capacity to accept tasks set by visitors many miles distant from its workplace. The article on the VALHALLA Project showed another mixture of ancient and modern in the way that two beautiful and long-established gardens, once the property of political rivals, were now using modern technology, including Virtual Reality Modelling to document themselves and safeguard their futures. So if the robots of 2002 did not appear to pre-dominate as was once feared, the article on the SciX Project nonetheless demonstrated that there were indeed disruptive technologies around and that in the case of electronic scientific publishing, not all had necessarily turned out for the best of all possible worlds, (with apologies to Voltaire).
Finally, from its "At the Event" reports and articles such as WebWatching National Node Web Sites, and the Praxis section on RSS, it will be possible for those historians to see how the First Information Age evolved. Furthermore, I hope they will sense the gratitude of this new editor towards all the contributors to this issue and not least to my colleagues at UKOLN, Marieke Guy (née Napier), Philip Hunter, Shirley Keane and Brian Kelly for their unstinting advice and support.

By Matthew Addis, Paul Lewis and Kirk Martinez - June 2002
Matthew Addis, Paul Lewis, Kirk Martinez and other members of the ARTISTE consortium review its achievements in developing an image retrieval system based on metadata and content that explores and analyses thousands of images from major art galleries across Europe.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
ARTISTE [1] is a European Commission-funded collaboration, investigating the use of integrated content and metadata-based image retrieval across disparate databases in several major art galleries across Europe. Collaborating galleries include the Louvre in Paris, the Victoria and Albert Museum in London, the Uffizi Gallery in Florence and the National Gallery in London.
Museums and galleries often have several digital collections ranging from public access images to specialised scientific images used for conservation purposes. Direct access from one gallery to another is currently uncommon for textual data and almost unheard of in terms of image-based search and retrieval. Cross-collection access is recognised as important, however, for example to compare the treatments and conditions of Europe's paintings, which form a core part of our cultural heritage.
A key aim of ARTISTE is to provide an image retrieval system that can provide integrated cross-collection searching. Whilst ARTISTE is primarily designed for inter-museum searching and as a building block for public access systems, it could equally be applied to museum intranets.
An article on ARTISTE in the first issue of Cultivate [2] presented the project objectives and technical approach. Now that ARTISTE is nearing completion, this article looks at how those objectives have been fulfilled and discusses future work to continue and build upon the achievements of the project.
The ARTISTE system currently holds over 60,000 images from four separate collections belonging to the Uffizi, C2RMF (restoration centre for French museums including the Louvre), National Gallery and Victoria and Albert Museum. Although these collections are stored in separate databases and all have their own unique schema for the metadata that describes their contents, ARTISTE makes it possible to search quickly and transparently as if they were a single entity.
ARTISTE has been well received by the user members within the consortium. Further feedback has been obtained after a scaled down version [3] was made available to the 70 members of the ARTISTE Interest User Group (AIUG) [4] as a publicly accessible dissemination system. The most notable features of ARTISTE include:
Users of the ARTISTE system search for images using a query wizard. The wizard prompts the user with self-explanatory and non-technical questions. The wizard permits forward and backward movements through the process of search-generation. In this way, users of ARTISTE can quickly and simply build up sophisticated queries without needing to understand the technical details about the algorithms being used and why.
Since ARTISTE is a distributed system of servers that are able to communicate with each other, a user starts the query process by selecting one or more image collections.
 |
| Figure 1: Selection of Image Collections |
The user then progresses to define the detailed aspects of the query, in which they might combine content-based retrieval with metadata searching. (More about these methods later). When users are happy with the query they submit it to the system. They can request to be notified by e-mail when the query is complete.
 |
| Figure 2: Final Step: Search Summary |
ARTISTE then distributes the query to the chosen collections and collates the results as they come back. While the query is executing, users are given constant updates on the progress of their query whilst waiting for the results to be returned.
 |
| Figure 3: Query Executing |
The results of a search are shown on successive pages of 'thumbnails' with either 9, 15 or 21 images per page. The use of thumbnails allows search results to be navigated quickly over the Internet.
 |
| Figure 4: Thumbnail results |
The images are ordered according to how closely they match the query. Clicking on 'more info' for a particular thumbnail retrieves the full size image.
 |
| Distance | 0.0 |
| Collection | VAM |
| ARTISTE Image ID | 12642 |
| Local Image Id | pcd8839390910005-008 |
| Figure 5: Full size image |
The results of all queries are stored in the system so users can go back to work they have done in the past.
 |
| Figure 6: Search history |
The results of previous queries can also be used as input to new queries to allow more refined searches to be made.
ARTISTE allows users to specify the type of image search they wish to perform. Some examples are shown below. Technical descriptions of some of the algorithms are presented later in this article.
This category of search uses the appropriate algorithm to find images that have a similar distribution of colour to the image submitted. The algorithm is automatically selected by ARTISTE, depending on whether the user is looking for colour or black and white images and also on whether a colour or black and white image is submitted.
If the user is looking for colour images and a colour image is submitted, then the algorithm selected will be 'Colour Coherence Vector' - CCV. Alternatively, if the user is either searching for colour images but submits a black and white image, or is searching for black and white images, regardless of whether a colour or black and white image is submitted, the algorithm used will be the 'Mono-Histogram'.
An example of a search for an image of similar colour is shown below. In this example, the query image is also contained within the database. It is therefore not surprisingly found in first place. The rest of the retrieved results contain areas of contiguous colour similar to that of the query image. This includes the background since the algorithm, unlike a human, has no way of determining what is the subject and what is a backdrop.
 |
| Figure 7: Similar colour search |
Typically a similar colour search would be used in combination with a metadata-based search. For example, if a metadata search for the word 'vase' was used in conjunction with this similarity search, only images of vases and containing a similar colour distribution would be retrieved.
This type of query uses an appropriate algorithm to find images that have a similar pattern to the image submitted. The algorithm used is the 'Pyramid Wavelet Transform' - PWT and matching is based only on the texture, i.e. repeating patterns, in the whole image. The example below shows the results obtained when searching for similar textures. In this case, the dataset contains a set of fabrics, and the similarity between the repeating pattern of the query fabric shows up clearly in the results.
 |
| Figure 8: Similar pattern search |
This type of search is also appropriate in a painting restoration context. Below is an example of a search for paintings with a similar layout of 'stretchers' (wooden planks) on the back of the painting.
 |
| Figure 9: Query image, stretchers |
 |
| Figure 10: Stretchers Results page |
The results from using this algorithm could be used as a measure of how many wooden planks are affecting the presence of damage such as cracks on the painting surface.
A query image may be a sub-image of an image within the database. The requirement is not only to identify from which parent image the query is derived but also to locate its position in the parent image. Some of the images in the collection are very large (up to 800 Mbytes) and also very high-resolution (20 pels/mm), demanding special purpose algorithms for effective handling. Since the query may have been recorded at a significantly different resolution from its parent and in a different state of restoration, or simply under different lighting conditions, robust algorithms are required. A multi-scale search technique based on colour coherence vectors has been developed and has given useful results.
If the user is looking for colour images and a colour image is submitted, then the algorithm selected will be 'Multi-Scalar Colour Coherence Vector' - MCCV. Alternatively, if the user is either searching for colour images but submits a black and white image, or is searching for black and white images, regardless of whether a colour or black and white image is submitted, the algorithm used will be the 'Multi-Scalar Mono-Histogram'.
The example query below shows the quality of results obtained. The matching is based only upon the general colour layout, where all the retrieved results contain areas of contiguous skin-like colour and areas of contiguous dark brown, similar to the colours in the query. To help the reader, we have indicated with a green rectangle the area in each result image that matches the query image. In this example it is actually the second result that contains the query image.
 |
| Figure 11: Sub-image results |
ARTISTE provides a colour-picking tool so that users can define one or more colours that they want to use as the basis of a search. The colours need not correspond to sizeable regions of an image since the algorithm used is based on how similar the colours in the image are compared to the colour selection.
The example below shows the results of a query where a particular shade of red has been defined using the colour picker tool (the interface to the tool is shown as the query).
 |
| Figure 12: Colour search results |
ARTISTE can attempt to retrieve images in a collection that match low quality monochrome query images, for example a facsimile of a painting that might be in the database. The retrieved images have a similar layout of dark and light pixels to the query image. An example of query by fax is shown below. An explanation of how the query image was analysed using PWT is given in the section Query by Fax.
 |
| Figure 13: Fax image results |
ARTISTE supports a wide variety of image analysis algorithms, some of which are described below. These form the basis of content-based retrieval. In some cases, the algorithms can be combined into composite queries and a normalised distance measure for each algorithm is used to determine the overall match of a result image to the query.
We have already looked at PWT, an algorithm that can be used to locate wooden planks, particularly at the back of paintings.
Another algorithm aims to detect the presence of cracks on a painting. X-ray images are used instead of conventional surface images, as they expose more clearly the structure of the cracks. These techniques are typically combined with a metadata-based search to limit the content-based search to a sub-class of the total image collection, for example images taken using x-rays or images of the backs of paintings.
In our system, each algorithm is applied to the images in the collection to generate a set of image content descriptors called feature vectors. A feature vector can be considered as a way of indexing an image to describe an aspect such as colour distribution or texture. The feature vectors are then integrated and stored with the text metadata for each image in the collection database. When a search needs to be made, the required algorithm (e.g. CCV) is run on the query image to create a query feature vector. This query feature vector is then compared with all the corresponding feature vectors for the images in the collection. The comparison of feature vectors results in a measure of distance between the query image and each image in the collection. The images in the collection are then returned to the user as a series of thumbnails in order of increasing distance.
Some of the individual algorithms are explained in more detail below.
The colour histogram-matching algorithm simply uses the frequency of occurrence of each colour of the histogram within the image. The more of a particular colour an image contains, the higher its frequency will be within the histogram.
The histogram is made with 64 bins, a compromise between speed (it takes longer to match more bins), and accuracy (the less bins the less discriminating the results would be - i.e. images which are less similar would have lower distances).
Before a histogram is used for colour matching it is normalised by the number of pixels in the image. This means that colour matching is not influenced by the size of the images that are being compared.
 |
| Figure 14: Histogram comparison |
Two examples of colour histograms are shown above. Note, in the second example, how the background is dominant in the image. Because the colours of the pots are spread fairly evenly over the bins, and the background is predominantly one colour and therefore one bin of the histogram, once the histogram is normalised the background dominates the vector. This is the main drawback of histogram matching: the background information is all included within the feature and it cannot be ignored.
In the first example, the background is more evenly distributed over bins (due to the shading) and the object groups into only a few bins (due to its flat colour distribution). Therefore the background does not dominate the histogram so much.
 |
 |
| Figure 15: | Figure 16: |
| Monochrome-man | Monochrome histogram |
The monochrome histogram-matching algorithm simply uses the frequency of occurrence of each level of brightness of the histogram within the image. The more of a particular brightness an image contains, the higher its frequency will be within the histogram. Colour images in the database are converted to monochrome for matching with this algorithm, by converting RGB values to monochrome. The reason a monochromatic histogram is required, is that the colour histogram is not discriminating enough for monochromatic images. A 64 bin colour histogram has only 4 bins dedicated to grey-scale values. This means that most grey-scale images would look similar in a colour histogram.
One problem with simple histogram matching is that no consideration is given to whether colour occurs in contiguous regions, i.e. large blocks, or is fragmented into many small areas. A CCV (Colour Coherence Vector) algorithm is used to address this problem. A coherent region of colours in an image is a region of colour that is larger than some threshold. The algorithm retrieves images which have similar distributions of coherent colours.
A histogram of 64 bins is generated for both coherent and incoherent colours and these are matched separately. Coherence and incoherence are arbitrarily defined as greater and less then 5% of the total image area, respectively. This means if a pixel is part of a region that is less than 5% of the total image area it is added to the incoherent histogram within the CCV. For example, the chessboard image below is 50% black and 50% white, arranged into 64 squares, where 32 are white and 32 are black. Each square constitutes a region, each of which is 1/64th of the total image area. This is approximately 1.5% of the image and hence is considered incoherent. If a pixel is part of an area that is greater than 5% of the total image area it is added to the coherent histogram within the CCV. For example, the second image contains the same amount of black and white (50% of each) as the first example, but this time the black and white areas are contiguous.
 |  |
| Figure 17: | Figure 18: |
| Incoherent regions | Coherent regions |
Finally, because the colour histogram, monochrome histogram and CCV algorithms only consider the characteristics of an image as a whole, they are not suitable for searches that look for a sub-image (query image) within larger images (images in the collection). To address this problem a Multi-Scalar version of CCV has been developed. As shown in the 'pyramid' graphic below, the algorithm divides the image into a number of tiles (e.g. regions divided by the white lines in the bottom level of the pyramid) for each of a number of resolutions (the three levels of the pyramid). Both the query image and the collection images are converted into such a pyramid structure, and then each of the tiles in the query image are compared against each of the features for the tiles in the database image using the CCV matching algorithm.
A similar method has been applied to the monochrome histogram-matching algorithm.
 |
| Figure 19: Pyramid graphic |
PWT allows retrieval of similar images based on the general texture distribution of the image. In this context, image texture refers to repeating patterns throughout the whole image.
The PWT decomposes an image based on a wavelet transform, which can be thought of as similar to a Fourier transform, which transforms the image domain into a frequency domain. The frequency components of the image are analysed and a number of descriptors generated which represent the amounts of a discrete number of frequencies in the image.
 |
| Figure 20: |
| Decomposition |
| in image domain |
 |
| Figure 21: |
| Decomposition in |
| frequency domain |
Images are resized to 512x512 to perform this decomposition, which yields 22 frequency descriptors for an image. This makes the matching very fast. The comparison is achieved using a standard Euclidean distance measure.
The query by fax is based upon a set of PWT measures of the image at various threshold levels of a monochrome instance of the image. A Query by Fax feature vector consists of 99 PWT features at various levels of threshold (between 1% black and 99% black) of the image.
 |
| Figure 22: Query by Fax: Database Images converted to 99 PWT levels on left, query image on right |
Matching is performed by a simple step process:
More detail on the algorithms can be found in the ARTISTE Interest User Group (AIUG) Newsletters [6]; in help pages accompanying the public demonstrator of ARTISTE [7] ; and in papers prepared by the University of Southampton [8].
Linking is a familiar concept on the WWW. The traditional approach is to embed hard-coded links in an HTML page, which point to another Web resource that is associated to the original page in some way. However, this has several disadvantages: links have to be specifically authored for each document, the linking is inflexible, and links are difficult to maintain. These negative aspects are circumvented with dynamic linking.
In ARTISTE, instead of hard-coding the links, a separate link database is maintained and the links are applied dynamically at presentation time. Links are applied on a keyword basis. If the keyword 'teapot' has a link to further information about teapots, then this link will be applied every time that the word 'teapot' is displayed.
As well as being dynamic, linking can also be distributed because each ARTISTE site can maintain its own link database with links relevant to its own users. Thus if users from the National Gallery accesses the ARTISTE system via their web site they will be presented with different links than those for users from the Uffizi.
Dynamic linking has several advantages over conventional hard-coded static links:
An example of dynamic linking in ARTISTE is shown below. This shows the result of an ARTISTE query (background) with links that have been dynamically added on the word 'teapot' so that the user can navigate quickly and easily to an on-line shop (foreground) that sells similar items.
 |
| Figure 23: Dynamic linking |
The facilitation of cross-collection access to digital image information has been identified above as an objective of ARTISTE. This means not only allowing seamless searching across the collections of the institutions participating in ARTISTE but also achieving interoperability between those collections and other digital library resources. To that end ARTISTE makes use of existing open metadata standards such as Dublin Core and RDF Schema, while also supporting the Open Archive Initiative (OAI) information retrieval standard for distributed access.
The goal of the OAI harvesting protocol is to supply and promote an application-independent interoperability framework that can be used by a variety of communities engaged in publishing content on the Web. ARTISTE is an OAI data provider and has implemented support for the Open Archives Initiative Protocol for Metadata Harvesting, thus providing open access to metadata stored with each museum and gallery collection. OAI service providers can use metadata harvested via the OAI protocol as a basis for building value-added services.
ARTISTE is also participating in an initiative to redesign the primary open standard for interoperability between digital libraries, z39.50, using web technologies such as XML and SOAP. The z39.50 into the Next Generation (ZING) initiative [5] has proposed a Search and Retrieve Web Service (SRW) based on the z39.50 protocol for searching databases that contain metadata and objects. ARTISTE is one of the early implementers of SRW and has devised a service which enables distributed image content and metadata-based searches over the ARTISTE collections. Having emerged from the digital library community z39.50 has been traditionally concerned with text based searching and ARTISTE has been working with ZING to incorporate into the SRW protocol the ability to deal with content-based searching and thus expand international standards of information retrieval.
The museum community requires more sophisticated 3D models and other multimedia objects to represent fully the artefacts in their collections. Out of the ARTISTE project, which has developed a 2D image retrieval system, a new project consortium has been convened to develop both the technology and the expertise to help create, manage and present cultural archives of 3D models and associated multimedia objects.
SCULPTEUR [9], again supported by the European Commission, will exploit semantic web technology.
The project objectives are to:
ARTISTE has developed a successful image retrieval system based on metadata and content capable of exploring and analysing thousands of images from major art galleries across Europe. The project has seamlessly translated local metadata schemas to common standards so that the individual collections are searched as if they were a single entity. Content analysis algorithms are now in place that can handle many different types of query, appropriate to the diverse needs of the museum community. ARTISTE is contributing to the development of open standards to enable interoperability between museum and gallery collections worldwide.
By enhancing facilities for multimedia information organisation, storage and retrieval, ARTISTE has gone a long way towards meeting the increasing need for intelligent information extraction and presentation from distributed resources.
A current constraint on the uptake of multimedia digital libraries is the limited amount of structured metadata available in such systems. However, there exists a large amount of relevant information on the Web, and with the emerging semantic web approach to information structuring there are many new and exciting possibilities for enriching multimedia information collections through information exchange with other repositories.

Peter Brophy reports on the COINE Project which is designed to encourage and enable ordinary citizens to tell and share their stories in networked spaces. Based firmly on emerging standards like OAI and Dublin Core, the project aims to demonstrate ways in which citizens can become contributors to as well as consumers of digital objects and can thus record, share and preserve their own personal and community cultures.

The Armitt Museum and Library in Ambleside, Cumbria, England has a history going back over a hundred years, being founded by the Armitt sisters, who lived in Ambleside and had connections with many of the leading British literary figures of the time (Ruskin, Rawnsley, less directly with Wordsworth, Coleridge et al.). They collected material relating to the literary scene of the day as well as that pertaining to the English Lake District - Ambleside is in the heart of this area, one of the most beautiful and most visited parts of England. Over time the Armitt added to its original collections, as it still does. Particularly notable are original watercolours by Beatrix Potter, better known for her Peter Rabbit and other children's stories, and the archive of the Charlotte Mason teacher training college and its relationship to the Parents National Education Union (PNEU). Part of the English Fell and Rock Club's collection is on permanent loan from nearby Lancaster University. Recently the Armitt has started to develop its collections relating to the work of Kurt Schwitters, the internationally-renowned artist who lived and worked in Ambleside for many years.
The Armitt occupies purpose-built accommodation near the centre of Ambleside, easily accessible to all residents and visitors. On the ground floor are the main museum display areas as well as a reception area and small shop. On the upper floor there is the main library collection, a reading room and an office.
Within the COINE project, the Armitt will be helping its local citizens to tell their stories using networked information tools developed within the project. What follows is a short scenario which illustrates the kind of activity that might occur:
| Alice has lived in Ambleside for the past five years. Now retired, she
bought her traditional Lakeland cottage from an old couple who had lived there
for many years. In redecorating she has come across many old features, and she
has started to research the history of her cottage and the people who have lived
there. She has discovered some old photographs of the street which show it over 100 years ago as well as more recent ones dating from the 1950's to the 1990's. She has found the names of former owners from the title deeds and has started to read documents in the Armitt and other local collections which suggest the occupations of some of these people. One was a prominent local artist. Having joined the oral history group, she has also discovered that some of the recorded memories of older residents have considerable relevance. By accessing genealogical sites she has found the birth and marriage certificates of the local artist and discovered that her parents came to England from Poland after the First World War. Now she is going to use the COINE system to write and record the story of her cottage. In searching the networked COINE archives she finds that someone in Poland, where another COINE domain is being run, has written the story of the artist's family. This will be a useful resource for her to link into. |
Local cultures exist in every part of Europe. They have many forms and expressions and there are many, sometimes unexpected, linkages between even widely dispersed cultures. Information and Communications Technologies (ICTs) offer the possibility of enabling individuals and local communities to capture, display, share and preserve their cultures in new ways, thus personalising both the publication and the use of information objects and exploring new inter-community linkages. In essence, ICTs offer the potential to turn citizens-as-customers into citizens-as-participants, actively contributing their own histories, knowledge, understandings and experiences.
Current evidence suggests, however, that where local communities are exploiting the web in an attempt to publicise and share their cultural interests, the implementations lack coherence, structure and interoperability. Neither are many of these solutions scalable or sustainable. Where generic standards are in use (for digitisation, resource description, search & retrieve and so on) the services tend to operate at national or major institution level. Where local and even sub-regional services and systems are implemented, it is more common to find simple web sites supported by lists of URLs or, at best, a locally-specified relational database. Furthermore, it is clear that the level of technical competence and skill needed to implement and maintain many of the IT-based systems available (such as museum or library systems utilising SPECTRUM, MARC, AACR, LCSH and the like) is far above that available to local communities. As a result citizens tend to be treated as relatively passive 'customers' rather than active 'participants'.
Robust, scalable and easy to use solutions are needed to encourage and enable individuals and small communities to actively exploit the opportunities of ICTs in worldwide networked environments. This is the issue which COINE is designed to address [1].
The following is a brief summary of some of the major challenges which work in this area has to engage with:
The consortium consists of the following partners:
The COINE technical architecture is designed to solve two specific problems:
In addition to the technical infrastructure issues, COINE addresses content personalisation from two angles:
Figure 1 shows a diagrammatic representation of the architecture used to provide highly distributed search platform for COINE. The architecture is an enhancement of the search platform developed within the EU FPIII DALI project [5], which was further exploited and enhanced within the FPIV UNIverse project [6].

| Figure 1: Highly Distributed Search Platform |
The different layers of this model can be described in the following way:
The search platform relies on two distributed data stores for its knowledge of underlying data stores and its user population:
The COINE publishing platform provides facilities for:
 |
| Figure 2: 'My Repository' Distributed Publishing Platform |
The different layers can be described as follows:
Quality control and structure are essential to success in this field. The chaotic lack of control of Web content has created many problems for those seeking to retrieve objects, since the authority of so much content is unknown. Quality control does not mean heavy-handed censorship, but implies that the provenance and quality characteristics of objects held in a COINE domain are known and displayed to users and that users have the tools to create meaningful descriptions. These functions may be exercised through the owner of a COINE domain (e.g. a local public library, art gallery, museum, school, college, university or consortium - or even a local group of people with a shared interest), which may in turn operate through appointed local agents or through individuals. The COINE domain also imposes standards, including metadata content standards, to ensure that objects can be identified across any number of such domains. As a result objects within a COINE domain are representative of the chosen local culture and are controlled locally - but are surfaced within a global networked space. In effect, COINE domains act as local art galleries, local archives, local museums, local history centres, and so on.
COINE demonstrators will be undertaken in a carefully-chosen, Europe-wide series of relevant and challenging implementations. Partners have already identified a wide range of application scenarios, as illustrated by the following list:
Demonstration partners were selected not just for the innovative case studies which they can provide, but for their close links with regional and national policy makers in the cultural industries. Thus COINE is designed to build on existing digitisation and 'culture surfacing' initiatives at regional and national levels, and to help build value-added linkages between these as well as the base-level local communities.
The COINE project enables the exploration of new concepts in 'information inclusion' by encouraging the ordinary citizen to become involved in network-based sharing of experience and heritage. It does so within a firmly standards-based framework, thus working towards widespread interoperability and long-term sustainability. Together with other projects in the 'Heritage for All' cluster, it will provide a baseline for major advancement in Europe in this exciting area.

By Robin Yeates - July 2002
Robin Yeates reports on the investigation by the COVAX Project into the suitability of XML in providing integrated access to collections and materials in libraries, museums and archives. He also draws conclusions on the Project's prototype and work with trial users.

One of the three research priorities of the European Commission funded IST Programme since 1999 has been 'ensuring integrated access to collections and materials held in libraries, museums and archives'.
How much progress have we made since then, and what are the current prospects for achieving what might be called a European Information Environment?
In the European Information Environment, everyone would have access to a range of appropriate and seamlessly accessible digital networked content and services provided by libraries, museums, galleries and archives. This would range from secondary indexes, catalogues and finding aids to full texts and multimedia objects and resources. These would be provided by the vast majority of existing institutions that have adapted their management practices and systems to participate in the environment.
One major technology component of the European Information Environment will be eXtensible Markup Language (XML), since this is rapidly becoming a basis for software application - software application and even to some extent software application - human interoperability throughout the quasi-global Information Society. This article looks at the policy context, but concentrates on the activities and findings of COVAX, (Contemporary Culture Virtual Archive in XML)[1], one of the few large-scale projects so far to look at the practical effects of a move to XML-based networking in European libraries, museums and archives. This article does not consider the related question of how far existing Z39.50 based solutions can meet the requirements, since this was not the focus of COVAX.
The European Commission has stepped back from its considerable activity in the field of innovation in digital heritage and cultural content, and commissioned an extensive and valuable study led by Salzburg Research entitled "Technological Landscapes for Tomorrow's Cultural Economy [2002]", known as the DigiCULT Report [2] . This tries to assess 'the way Europe's cultural institutions should approach technology-driven mutation' and make recommendations.
The DigiCULT Report Executive Summary begins 'Being digital for many European archives, libraries and museums (ALMs) is no longer an option but a reality. They have turned into "hybrid institutions" that take care of both, analogue as well as digital cultural resources. The conversion of all sorts of cultural contents into bits and bytes opens up a completely new dimension of reaching traditional and new audiences by providing access to cultural heritage resources in ways unimaginable a decade ago'.
Many of these cultural heritage or memory institutions have for years been managing their collections using sophisticated and expensive commercial software systems. They have been considering how they might migrate or replace their software systems to ensure that their resources are available to those who need them in the new era of the Information Society.
Others, especially smaller institutions, may not be so concerned about existing or future software investments, but they need to ensure that their own holdings become more visible and accessible in the networked environment. Large commercial endeavours that compete more effectively on the web may eventually threaten to substitute alternative, poorer quality services for those traditionally provided by small institutions.
From a supplier perspective, it is becoming increasingly important to offer products and services that inter-operate effectively with those of other suppliers, at least at a basic level. Alliances and partnerships need to be developed, particularly between management systems suppliers and content aggregators and large publishers. Moreover, they need to be based on workable architectures and practical ways of migrating from current infrastructure and customer/client environments to those expected to become more widely available. Smaller publishers will need to make their primary or secondary works available through larger intermediaries. If this is to happen, all the stakeholders involved need to develop a shared understanding of the issues so that they can contribute to successful innovation.
There is no doubt that a strategic political demand exists to encourage sharing of cultural data, although it has yet to be fully recognized that such work can only indirectly be self-sustaining, through education, social cohesion, personal motivation and self-fulfilment. At present the emphasis has been on technologies, rather than on these indirect benefits of wider access to and use of cultural resources. One of the Lund Principles of 4th April 2001 taken up within the eEurope digitisation strategy is that the Member States could make progress on the eEurope objective to 'create a co-ordination mechanism for digitisation programmes across Member States' if they 'worked in a collaborative manner to make visible and accessible the digitised cultural and scientific heritage of Europe.' (Lund Principles, 2001)[3].
A European Information Space may develop as a logical extension of national policies. For example the Heritage for All projects of the 5th Framework Programme CHIMER, CIPHER, COINE and MEMORIAL all intend to develop new and more powerful tools and services that involve cultural heritage organizations such as museums, archives and libraries more in end user learning and allow users to interact more deeply with content held by or delivered via them. Programmes such as the public lottery funded Peoples' Network in the UK will produce far deeper understanding within the cultural sector of the more complex issues relating to the management of digitisation and may generate support for future integration with other European programmes. However, COVAX has demonstrated that there still remains a large number of technical issues to be resolved simply to enable the sector's 'legacy' resources to be made visible and accessible to web users.
In Issue 3 of Cultivate Interactive, January 2001, Carlos Wert and Francisca Hernández described the aims of the COVAX project at its start [4]. The main objective of the project that ended in December 2001 was to define the different phases and procedures that need to be followed to transform current management and information systems used in archives, libraries and museums to an XML environment.
Here we outline the actual creation of a prototype resource discovery system containing a wide range of content types, its internal formative assessment and a summative evaluation of the outcomes of the project, some six months after completion, from the point of view of one of the partners.
One obstacle to technical development is that a realistic pool of digital data for modelling future systems is not always readily available to researchers, since priorities and formats have not yet been fully defined by local managers. Since the kind of information required to be discovered and managed by network discovery tools is in a state of constant flux, pragmatic approaches have to be taken during projects of fixed, tight time-scales.
One answer to this problem has been to focus on existing, often subject-based communities. These will have more clearly defined aims and target user groups, and will offer a clear vision that builds on the present.
If we are to expect new forms of interdisciplinary learning to develop, however, we must develop ways for new communities to be built that are founded on new ambitions and opportunities created through the network itself. These communities will have to set their own technical standards and guidelines, and potential members will need to be able to accept and adhere to them without causing prohibitive local disruption.
In practice, COVAX content used to build the two prototypes to date does not form a coherent dataset for any particular community. Instead, we have used samples that enabled development of solutions for what will become widespread problems. In effect we have taken a worst-case scenario, and considered the surrounding issues, rather than creating a finished product. The resultant in-depth learning, however, has meant that all partners feel confident in their technical planning, and indeed partners intend also to continue working together on their future systems, as they found the processes involved in technical integration and development so beneficial.
The actual data used consisted of mainly text and textual metadata, with some related images, as follows:
There are two main approaches to the use of existing data for XML based delivery. Data can be exported from existing systems in batches and converted directly or indirectly to XML. Alternatively, it can be left in an existing, typically relational database, and converted dynamically on demand.
Neither of these main approaches is likely to provide a complete solution for all memory institutions. One reason for this is that the size of collection and range of data management options varies enormously. Contributors may only require to publish a small number of records, or may require a complete separation of their management system from the network for security reasons, making a dynamic interface impractical. Conversely, large datasets that must be made fully accessible from existing systems may be impractical to handle using batch transfers.
A further issue is how to maintain interface compatibility across numerous disparate sites, especially now, when standards are still being extensively revised and developed all the time. COVAX solved this problem by introducing its own control over the range of open standards used, and by developing an agreed architectural framework for expansion. The system was able to layer services and content transformations so that contributors could be fully supported, whether they had no local XML systems or skills at all, or whether they had newly established, advanced, multimedia XML repositories, or whether they fell, like most institutions, somewhere in between.
The data conversion efforts undertaken have been described elsewhere with examples (ELPUB, 2001)[5]. It is sufficient here to note that we found that the existence of a strong service support network for data management was crucial to content providers to make their content available. This support ranged from basic and advanced XML/XSL skills to specialist knowledge of the source data formats. These were mainly MARC-based formats in the COVAX case, but several variants were used by partners, and it was decided early in the project that conversion to MARC21 should be undertaken to simplify conversion to XML. There is in general a distinct lack of bulk record conversion and validation tools that work with cultural schemas.
This meant we were able to use existing facilities to batch convert data, and we could leverage work done by the Library of Congress and others. A policy decision to use existing tools wherever possible led us, therefore, to make use of a fully reversible MARC21 based LoC XML format, rather than invent our own simplified solution. Local projects should not need to undertake such technically complex work, and we feel that we are now in a good position to utilise newer schemas and DTDs as they become available, without being required to develop them ourselves. This latter course of action might have severely restricted our capacity to integrate with future developments, although it may have led to some short-term benefits, such as improved performance of the COVAX prototypes. A huge benefit of this approach is that it is possible to include new data conversion and dynamic interfacing service providers into the consortium network, and to migrate practices over time as content providers gain skills and local systems capabilities, such as XML query handling.
Most of the time, memory institutions, particularly libraries and larger museums or archives, that want to publish large amounts of content will already have management systems using SQL-accessible relational databases such as MS Access, Oracle or MS SQL Server. Z39.50 techniques have already allowed integration of such systems to some degree for resource discovery. COVAX was tasked with determining whether so-called native XML databases might also be used. They would allow any XML resources to be held and managed in purpose-built repositories that provide access to objects, documents, statistics and other functions via web browsers and XML clients. In this way bibliographic information, finding aids, metadata and full-text documents and related multimedia assets can be retrieved in whole or part using not only SQL but also XML-based queries. These native XML databases are now becoming widespread as the basis of new content management systems, and as they become more sophisticated and robust, they will either replace or provide additional options for data management and security.
 |
| Figure 1: COVAX Deployment |
COVAX began in 1999 when few native XML database options were available, and no partners currently had one installed. It was not our intention to explore the full potential of these systems during the project, but we did need to create a distributed network of them to provide our testbed.
A key partner, Software AG, offers the Tamino product [6], and this was offered to the content provider partners, some of whom installed it, running under both MS Windows and Solaris on a Sun platform. A high-end solution, such a platform is intended for enterprise level applications, but we had no serious difficulty setting up and using it for five servers in Madrid, London, Rome and Salzburg. For the project these sites supported some ten production databases and five test databases. The whole system is managed via web browsers apart from some bulk processing and similar scripts.
Content providers felt the need for a simpler lower-cost solution for add-on repositories to existing systems. Only one suitable product was found at the time, lthough more have become available since. TextML™ [7] from Ixiasoft was used to develop an additional seven production databases and one test database in Barcelona, Karlskrona, Sweden and Graz. AIT needed to provide some additional software for this system, so that the COVAX meta-search engine could use a single query format to query both Tamino and TextML repositories. XPath [8] and XQL were used for the query language in COVAX, but there are still some issues surrounding the immaturity of these standards.
In the future improved XPath/X Query standardisation and wider-take-up by suppliers is likely to reduce or even eliminate the requirement for adaptor software for each native XML database system. This will be essential for full interoperability of systems.
Each database holds a collection of XML documents that use a particular schema. Schemas were issued centrally to consortium members by the technical partners, Software AG, Madrid, Salzburg Research and AIT in Graz. These included Marc, Amico, TEI headers and EAD schemas using open externally published schemas adapted only where absolutely essential in minor ways for operational reasons or to correct errors. A great deal of work was required by content provider staff experts to develop suitable mappings from all the accepted COVAX formats to the required index access points, based on the Dublin Core Metadata Element Set to allow cross-domain searches. In addition to this work, of course, each partner also had to provide appropriate mappings and conversion from a much wider range of local formats.
In addition the COVAX holds XML records based on the principle of Z39.50 Explain, describing content providers, systems information and collection information (collections were referred to as databases during the project). For these, a set of new schemas was prepared and content was supplied in one of six native languages and English, then translated into all the others by the relevant language partners. Users therefore have access in their native language to collection level information content at least.
 |
| Figure 2 : Part of a COVAX XML Explain document |
Altogether we created some 17 production databases and 6 test databases containing the collections in Figure 3:
 |
| Figure 3: COVAX Content |
One of the main requirements and benefits of the project was to develop our understanding of XML at both technical and information professional levels. This we achieved by carrying out a survey of the state of the art of XML handling software (available on the project website), and by making use of market-leading tools. The most important such tool was XML Spy, an IDE (Integrated Development Environment) from Altova GmbH. Available free or open-source XML tools were not found particularly suitable or easy to use, especially compared with tools available for HTML, web authoring, java and JavaScript related purposes. XML Spy supports the full XML syntax, parsing, well-formedness, validation, encoding; DTD definition; schema definition; XSL and XSLT management; HTML and XHTML rules (this last is a superset of HTML4.0 rules that adds to markup a more rigorous syntax and compatibility with XML environments); syntax highlighting; interoperability with other external applications (imports for example from MS Word, MS Access); some of ASP etc. Such a tool was found suitable for technical staff and skilled authors, providing us with the means to ensure only valid content reached the repositories, and to test and check COVAX meta-searching. However, we did find problems when trying to validate large batches of records, typically exported from existing management systems, since most tasks required all records to be held at once in main memory. For this reason, and because these tools are generic, partners also used other techniques to validate and correct specific types of content and to convert character encodings where necessary.
In order to evaluate usability and design issues, two prototype COVAX versions were built in Java code, using XML files for configuration and storage information and XSL stylesheets for transforming XML from one form to another. The second version contained the final set of project COVAX features. A shared gateway user interface for resource discovery was created allowing browsing of collections in six languages and cross-searching of all the distributed repositories, although a public version has not yet been made available. It is possible for users to select their preferred interface language, and the system architecture is designed to hold group or personal profiles and persistent storage between sessions, along with search histories and statistics. However, where possible, such facilities would be provided using existing authentication or storage services, and the open architecture also allows search aids such as thesauri or XML transformation and enhancement services to be added at a later date.
COVAX is essentially 'middleware', not necessarily visible to end-users, but capable of enhancing portal or local web services by delivering an integrated stream of Dublin Core compliant XML or HTML formatted records for diverse types of cultural content from a consortium of content providers. It provides:
 |
| Figure 4: COVAX Architecture |
A fuller description of the user interface has been published in Program (Yeates, 2002), but the figures following show a logged-in search forms and brief search results. Full search results displays vary depending on the resource type, but are displayed at least partially in sequence on a single results page for speed of in-page navigation.

 |
| Figure 7: Results from an Austrian museum image collection (AMICO format) |
COVAX has implemented a complex demonstration of a fully XML-based resource discovery network that has taken great account of the wide variations in cataloguing practices throughout several European countries. However, it is not yet a complete product.
Users should drive the design of any system, although hidden systems, such as much of COVAX is, present design collaboration challenges. Part of COVAX consists of elements specified by cultural and information professionals. Other parts were designed by expert web technologists. Therefore it was important to involve outside stakeholders and users in shaping further development of the system. Expert usability assessment advice was provided from outside the project team but within one of the partner organisations, Salzburg Research.
A complete usability assessment framework and usability toolkit were created, through a project workshop followed by individual partner development work. Then we had a clear target groups matrix, some usage scenarios for each and instructions and worksheets for carrying out interviews, observations and questionnaire pre- and post-trial surveys at a wide range of sites internationally. Work was undertaken over a short time period, but generated much useful information as a result of the careful planning, especially as we could directly compare independent results.
Feedback was contributed by many stakeholders, ranging from those responsible for national digitisation policy to web researchers, cataloguing experts, non-specialist academics and the general public. Groups studied were:
The main conclusions of the user assesment were:
Overall, the issues arising from these assessments were no surprise to the consortium, because the main problems had already been identified: long waiting time for answers, time outs, results ordering and revision of the interface design. These modifications have been discussed during consortium meetings and kept for future developments, some of which will depend on general improvements in XML networking.
We have shown that it is feasible to migrate legacy cultural services to an XML environment, and that there are benefits for users if this comes about. They may gain more immediate access to deeply linked, high quality content held in a multitude of European, and indeed global, repositories. Awareness of materials will rise as certain multilingual access and customisation facilities can be implemented relatively easily using XML and XSL. However tools are not yet fully mature, especially within the cultural heritage sector. Services can however be built now that encourage staff development and stakeholder involvement.
The COVAX partners continue to develop their repositories, but we expect much to change in terms of access arrangements and ultimate service design, as we develop understanding of new professional and commercial opportunities.
Silke Grossmann, Vic Haesaerts, Gerda Koch and Walter Koch [2002] have reported on the REGNET Project [9] which aims to set up a functional network of service centres in Europe, providing IT-services dedicated to Cultural Heritage organisations. This may be one useful way forward, and there are other initiatives of a similar scope underway.
We recommend urgent attention is paid, however, by all institutions, large and small, to XML. The complex MARC21 DTD used by COVAX is likely to be replaced by more appropriate XML based information models for bibliographic data. Presentation of full-text documents and lengthy finding aids requires improved techniques for adapting content for resource discovery to improve performance. Too much nesting of elements in XML documents obstructs mapping of access points and indexing. The standards and protocols for searching distributed databases need to be improved, and adaptation of Z39.50 for HTTP and XML is a promising approach.
The COVAX architecture is not just applicable to cultural heritage applications, but applies also to distribution of information about elearning products or tourism information. The principle of cross-domain searching was strongly endorsed by COVAX trial users, but much more work is needed by everyone to provide appropriate content and system performance so that a full European Information Environment can be achieved.
So, what of the future? An increased emphasis is likely on support for the autonomous learner, in order to support the concept of lifelong learning and not merely formal education whilst at school, college or university. Learners, as opposed to teachers, need to be able to interact more deeply with resources, and teachers want to capitalise on new digital resource provision, in order to gain the benefits of improved student motivation and self-confidence that these resources can generate.
We certainly need to include legacy materials in the mix of learning opportunities. However, it may be more important to explore how we might build new innovation platforms for the creation and development of new cultural heritage services that will attract future learners.
Evidence from Covax shows the value of XML in resource discovery, but also the need for agencies to provide ongoing data conversion services. It shows the value of developers working with intermediaries, but also the challenges of delivering meaningful services without wider partnerships being created.

By Jutta Weber - July 2002
Jutta Weber observes that European culture is mainly based on the tradition of text and that the preservation of the written word is one of the essentials of cultural heritage programmes. Here she writes about an initiative which enables all institutions in Germany holding hand-written documentation of a European cultural nature to present data effectively about their holdings, and themselves, on the Internet.

The project Kalliope (Verbundinformationssystem Nachlässe und Autographen) is co-ordinated and carried out by the Berlin State Library (Staatsbibliothek zu Berlin) [1] and |a|S|tec| - Angewandte Systemtechnik GmbH [2] and co-funded by Deutsche Forschungsgemeinschaft [3].
One of the most fascinating aspects of Europe's cultural heritage is the fact that every country owns a considerable number of collections of modern manuscripts and letters, written by the most famous and the less well-known, but which together form the backbone of our European culture. As cultural life has never been isolated within one nation or region, all kinds of national and international relationships exist between these collections. Europe's cultural history is defined by these relationships and its documentation is maintained in institutions with archival functions, not only in Europe but all over the world.
In 1966 the Union Catalogue of Modern Manuscripts and Letters in Germany was established in the Staatsbibliothek zu Berlin. Today it provides information about more than 1.5 million documents relating to 250,000 people. More than 150 partner institutions regularly provided this information by sending copies of their card catalogues.
The documents represented in this catalogue date from early modern times up to the present day. Among those people whose manuscripts and letters are documented there figure the most famous poets, artists, scientists and politicians of Europe but also less well-known people who survive in the Union Catalogue as they corresponded with those famous people. The data include brief information about archival collections, single letters or manuscripts kept in archives, libraries and museums in Germany. As these institutions differ in size and importance and have very different functions - there are small local archives as well as large universal libraries - the collections they own may be of importance on a local, national or even international level.
The Union Catalogue is a meeting point for scholars from all over the world who need information about the location of manuscripts and letters in Germany. It also represents a kind of interface between archival, library- and museum-related documentation and the administration of manuscripts and letters.
Catalogue conversion which started some years ago has now reached the point where results can be presented on the Internet. This data will appear together with that from a large network of cataloguing institutions to be established throughout Germany. All will be presented under the name Kalliope.
The goal of Kalliope is to establish in Germany a national node, acting together with all the German partner institutions as data provider in the European network MALVINE (Manuscripts and Letters via Integrated Networks in Europe) [4]. Kalliope will build the bridge between these partners and the MALVINE community. MALVINE is a search engine building the basis of a network of data __ namely collection level and item level descriptions __ of modern manuscripts and letters held in various European institutions.
All information contained in the card catalogue of the Central Catalogue of Manuscripts (Zentralkartei der Autographen) will be made available in Kalliope electronically, as mentioned above. This means that more than a million data items on literary archives, manuscripts and letters relating to more than 250,000 people can be searched on Kalliope. This will be the basic provision, but it will be regularly updated with new data from former and newly participating institutions.
There are two search options:
 |
| Figure 1: Search for Documents |
 |
| Figure 2: Search for Persons |
To generate a high level of usage, participation in Kalliope is in fact open
to every institution.
The institutions can choose between:
 |
| Figure 3: The Kalliope Co-operation Model |
With these four options Kalliope is able to communicate with every sort of institution holding relevant material:
All records available on Kalliope are presented by Berlin State Library in the Kalliope OPAC which is freely available on the Internet under http://www.kalliope.staatsbibliothek-berlin.de/.
The German cataloguing tradition in the sector of modern manuscripts aims at giving information on both the collection level and the item level description of each document (whenever possible and meaningful) and is based on two standards:
Both are indispensable in a communication network designed to show specific material in a coherent framework. In Kalliope a very simple mechanism connects name authority records to corporate body authority records. It therefore provides comprehensive information on where documents on particular people are held.
 |
| Figure 4: The Kalliope Internal Model |
This relationship is a 1 (person or institution) to n (institutions) relationship and is the basic structure of the model "DIANA" (Deutscher Index zu Autographen und NAchlässen). The possibility of just adding (via an electronic template) the name of an institution (or a private person) holding material on a person or institution is the simplest way of enhancing the Kalliope information service.
 |
| Figure 5: full result display on Person Search |
Some aspects of this DIANA model have influenced the idea of the project LEAF (Linking and Exploring Authority Files) [16]. LEAF, co-ordinated by Berlin State Library is developing a model architecture for a central server connected to a distributed search system harvesting existing name authority information with a view to automatically establishing a user needs-based common European name authority file.
Kalliope demonstrates that the preconditions for constructive and well-organised participation in the realisation of a European or international co-operation model can be established and that these can include more than just the biggest and best known institutions in this strategic goal. Only when all relevant institutions - including the smallest ones - are able to participate in the realisation of a European or even world-wide initiative, will it ever be possible to create a telling contribution to the "information society". This also means that every kind of institution - museum, library, archive, documentation centre, scientific institution - must have the chance to provide its information in a suitable way.
And so we envisage a virtuous circle: the more institutions that allow access to their data on Kalliope, so the more data will be available in MALVINE and the more terms of comparison will be available, and examples of "how to do" will be provided world-wide. This is in fact one of the expected outcomes of Kalliope on the national, and of MALVINE, on the international level: to give as many examples as possible of how Europe's modern manuscripts and letters are described and how they can be found in terms of this kind of description. The goal is to encourage new participants to do so in the same way. The use of authority information - the enhancement of which is the principal aim of project LEAF - will provide more focussed access to data. The network of information about the relationships between persons and institutions will become denser and more complex with every new participant in the projects. Thus Kalliope and MALVINE and, in the future LEAF, will have an increasing influence upon each other: Every public user, every expert, every participating institution, indeed country, will profit from these initiatives in the long term.

By Richard Wright - July 2002
The longer established European broadcast organisations are now facing a considerable challenge in preserving large broadcast archives that risk irreparable degradation through ageing. Richard Wright highlights the problems confronting broadcasting organisations and how technical developments produced by the PRESTO Project can help.
|
EC Project PRESTO has completed a survey of the holdings and preservation status of ten major broadcast archives. These archives represent a significant portion of total European broadcast archives, including some of the largest individual collections. Approximately 75% of this material is at risk or inaccessible. The collections are growing at roughly four times the rate of current preservation work. The technical developments produced by project PRESTO reduce the costs and improve the effectiveness of multimedia archive preservation projects.
The Twentieth Century was the first century with a record of its significant events - the sounds and moving images - on film, audio and video media. A major repository for this record is the collective broadcast archives, particularly the archives of major broadcasters. In Europe, the main broadcasters are publicly supported, leading to archives that have a role not only in the business of broadcasting, but also fulfilling a public service requirement to support wider educational, cultural and heritage purposes.
This record is now largely at risk, as the bulk of these recordings reach the stage at which they are deteriorating, or on an obsolete format, or both. Broadcasting was never developed as a mechanism to create and hold permanent audiovisual history. The consequence is that these archives have arisen to support broadcasting, and have no business model or funding model specifically designed to support preservation.
EC Project PRESTO has the aim of increasing the efficiency of the technical work needed to preserve broadcast archives. The efficiencies are of two sorts: reducing costs, and developing strategies to ensure that archives are not simply physically preserved, but preserved in ways which maximise their future benefit. To get the size, shape and urgency of the problem, a survey was made of the holdings and preservation requirements of ten major European public service broadcast archives (details of the PRESTO project and survey participants are listed below in Appendix I).
The survey covered the following areas:
| The present | What broadcast archives do: their place in the business |
| What they hold (media types, size of holdings and condition) | |
| Current preservation practices: technology, processes and costs |
| The future | Service requirements: new services for new holdings |
| Preservation requirements: new technology and processes |
The ten archives in the survey represent a significant portion of total European broadcast archives, including some of the largest individual collections, but total European holdings of broadcast material are probably ten times larger. The survey found about 1 million hours of film, 1.6 million hours of video recordings, and 2 million hours of audio recordings in the ten archives.
The content covers the entire century, as broadcast archives include bought-in film and even wax cylinder material from before the development of the broadcasting industry. The record of news, current events, sports, culture and entertainment covered in radio archives dates from the 1920's (recorded originally on shellac discs), and there are film recordings of television output from 1936 onward.
Access to this content is notoriously difficult, because almost all the material is on 'professional' formats (film, broadcast-standard videotape) which need special players, certainly unavailable to the general public and often unavailable even to national archives and educational institutions. Also much of the content is unique, master material that cannot be allowed to circulate generally. A major goal of preservation work for broadcast archives must be to find joint solutions to preservation and access problems: preservation for access.
The amount of audio, video and film material in the ten archives surveyed is given in the following diagrams:
|
| Figure 1: Audio Holdings |
|
| Figure 2: Video Holdings |
|
| Figure 3: Film Holdings |
Obsolescence: At least 2/3 of the material in archives cannot easily be used in its existing form, because the medium is too specialised (film) or obsolete (2" videotape) to allow easy access. For audio, this includes the massive holdings on ¼" open-reel tape.
Deterioration: Approximately 1/3 of the material has one form or another of deterioration:
Fragile media: A large part of the holdings cannot be released for access because the media are too easily damaged. Examples are: all film negatives; all film prints except for access by qualified professionals; all shellac and vinyl audio recordings.
The main approach to preservation of video materials is transfer of old formats to new formats. It must be stressed that these transfers do not constitute true preservation - they simply solve today's format incompatibility and tape wear/degradation problem by creating an identical problem to be faced - at equal additional expense - in as little as ten years in the future.
For audio, however, the approach is increasingly to transfer the material to digital files which can be held on magnetic or optical media (datatape, CD, DVD). This approach allows future transfers to be fully automated using media-handling robots - and so the mass digitisation to a "robotic formal" is a significant step toward true media preservation.
Digital videotape is somewhere in-between analogue media, which is expensive to transfer to new formats, and computer files for which condition monitoring and media transfer can be fully automated. The technology for "preservation work" being developed by PRESTO is aimed mainly at processes for conversion of older analogue formats (for audio and video). Cost-effective approaches to the preservation of digital videotape and digital audio are being developed by the related EC-sponsored project AMICITIA[1].
Preservation is a major issue, but cannot be viewed in isolation. The institutions which hold this endangered material perform services, and broadcast archives serve a highly technical and rapidly changing industry. Preservation strategy needs to consider - to foresee if possible - the future service requirement of multimedia collections for at least the next twenty years. These service requirements will increasingly be based on electronic mass storage and direct, networked end-user access - probably using web technology. The critical question is: how much preservation money should be invested in the additional steps required for conversion of existing media to new technology? This raises the related issue of how to estimate and justify the additional expense. PRESTO has developed a strategy for dealing with this problem, based on the concept of 'cost per use'.
The true cost of an asset is total lifecycle cost. The true benefit is related to the number of times that asset is used over the lifecycle. Although not every use has equal benefit, overall more media issued from the archive means more benefit to the broadcaster and to the wider public service. Therefore a simple way to combine transfer cost, life cycle cost, and the significance of new service opportunities, is to translate those new opportunities into a predicted rate of item usage. Options for preservation can then be compared, in monetary terms, on a "cost per use" basis. A significant conclusion of the PRESTO survey is that archive preservation strategy should aim at the "lowest cost per use" over the life cycle of the new media, NOT at the lowest transfer cost.
Digitisation and mass storage is about 50% more expensive than just transferring from old formats (carriers) to new formats, but the new technology allows much easier access to the media. Simpler and faster access has already been shown to double at least the usage of an asset. This means it is cost-effective to spend the extra 50%, because the extra investment more than pays for itself in terms of extra usage of the material, i.e. in terms of lower overall cost per use.
Although advanced technology using mass storage has the highest initial investment, it has the lowest overall 'cost of ownership' because it allows the greatest automation of future preservation work.
PRESTO has identified 12 specific key links covering both radio and television archives. The new technology being developed or integrated will either reduce costs or increase the benefit of the whole transfer chain - or both.
Manufacturers of videotape recorders (VTRs) cannot be expected to incorporate the advances in videotape technology into new players for old formats - because old formats are by definition obsolete. Three areas related to improving the performance of VTRs are under development, concentrating on 1" and ¾" (U-Matic) formats.
Broadcast archives are in the early stages of the biggest and most expensive media conversion they will ever face. The whole process of selection and digitisation of analogue media will take at least another 20 years. Without widespread funding and support, and without cost-effective and farsighted use of technology, the work will not keep pace with the deterioration of the material. EC project PRESTO has documented the problem and provided guidance for organising preservation transfer projects. PRESTO has now delivered multiple forms of new technology for reducing preservation project costs, and increasing their efficiency. The future of PRESTO lies in maintaining information flow to all involved in archive preservation.

Rob Davies gives us a progress report on Europe's Thematic Network for Public Libraries and cultural institutions operating at local level.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Since its inception in May 2002, the PULMAN Network of Excellence has set out to strengthen the performance and help achieve the potential of public libraries in their emerging new roles and to help them prepare to fulfill their potential in the digital era of an e-Europe.
PULMAN's major work involves:
A key outcome of PULMAN is to encourage integrated activity involving public libraries, museums and archives operating at local level.
The PULMAN Network is now firmly established with representation from 26 European countries and a further 10 to follow (see below). The first twelve months of activity have been a very productive period.
Work has now been completed on drafting the first edition of the PULMAN Digital Guidelines and they will shortly be available on PULMANWeb [1]. The draft Guidelines were evaluated at a workshop, attended by 69 experts from 35 countries, in Helsinki on 18/19 February, 2002. The experts, which included PULMAN's own Virtual Advisory Board, assessed the Guidelines from all perspectives including format, usability and content. The result of the Workshop was to establish a well-defined editorial framework for the finalisation of the Guidelines. They are now ready for publication on PULMANWeb during June 2002. Proposals for their translation into 18 national languages have already been received.
The 122 million registered users of public libraries in 29 countries of Europe attest to the importance and impact of public libraries in society. To realise their full potential in the digital era, public libraries must be prepared to offer new and innovative digital services that empower citizens to achieve their personal goals in a changing society and to contribute to a cohesive and successful knowledge-based economy in Europe.
The Guidelines are intended to point public libraries and - more tentatively - their local cultural partner organisations, into this era. They include sections on: Policy Issues; Good Practice; and the Future Agenda - together a very wide range of links to innovative services.
The Guideline contents are as follows:
| Introduction |
| Section 1 - Social Policy guidelines |
| Social inclusion |
| Citizen participation in new forms of civic governance |
| Access and services for people with physical and visual impairments |
| Public library services for children and schools |
| Public library services supporting education in adult life |
| Support for business and the economy |
| Access to diverse cultural content |
| Access to music and non-print material |
| Section 2 - Management guidelines |
| Performance measures and evaluative tools |
| Funding and financial opportunities |
| Management practices and models for co-operation and partnership |
| The public interest in access to copyright-protected materials |
| The handling of legal issues |
| Section 3 - Technical guidelines |
| Digitisation |
| Developments in integrated library systems |
| Multimedia digital service delivery |
| Delivery channels |
| Resource description, discovery and renewal |
| Tailoring of services and citizen interaction and participation |
| Technical responses to multilingual issues |
We do not expect that the Guidelines will be a perfect instrument in their first edition and, for this reason, will be inviting comment from all interested parties via a process of Open Review which will lead to a revised edition in time for the Policy Conference in March 2003 (see below).
Perhaps the first use of the translated Guidelines will be to provide a basis for discussion at the 26 PULMAN National Workshops scheduled to be held in September and October 2002. The Workshops will also try to move forward the agenda for cross-domain activity and co-operation among public libraries, museums and archives.
Feedback from the National Workshops will feed into the planning and agenda of the PULMAN Policy Conference.
In support of this cross-domain agenda, a meeting was organized by EBLIDA (European Bureau of Library, Information and Documentation Associations) on 7 June 2002 in The Hague. This involved participants from a range of European organisations and associations from the museums and archives sector in the discussion of the terrain for co-operation between public libraries, museums and archives as well as contributing further to the Policy Conference agenda.
The PULMAN Policy Conference will be held in Oeiras, Portugal (13-14 March 2003). Its target audience is policy makers and influential practitioners in public libraries and their partner institutions. EBLIDA is co-ordinating and planning the Policy Conference.
PULMANweb [1] now provides access to a growing variety of resources and information - The Guidelines will be the newest arrival.
The following table summarises applicants and participation in the Training Workshops:
| Country | Applications | Participants |
| Bulgaria | 5 | 4 |
| Czech Republic | 3 | 3 |
| Estonia | 4 | 3 |
| Greece | 15 | 7 |
| Hungary | 3 | 2 |
| Latvia | 1 | 1 |
| Lithuania | 9 | 5 |
| Poland | 12 | 6 |
| Portugal | 8 | 5 |
| Romania | 4 | 4 |
| Slovak Republic | 2 | 2 |
| Slovenia | 7 | 5 |
| Spain | 1 | 1 |
| Total | 74 | 48 |
Finally, PULMAN is growing! The proposal to extend the PULMAN Network to countries bordering European Union countries and its candidate states, favourably evaluated under the 8th Call of IST FP5, is in the final stage of negotiation at the time of writing and expected to begin in mid-June, 2002.
The countries involved include Russia and Turkey (as partners) and a number of other countries represented by Country Co-ordinators (Albania, Belarus, Bosnia Herzegovina, Croatia, Macedonia, Moldova, Montenegro, Yugoslavia and Ukraine).
PULMAN-XT will run for 14 months and will enable the new countries to benefit from the work of PULMAN including translated Guidelines, National Workshops and attendance at the PULMAN Policy Conference. In addition, an ambitious new programme of institutional mentoring and twinning will be established.
MDR Partners (UK, co-ordinator), Eblida, Helsinki City Library (Finland) , Oton Zupancic Library, Ljubljana (Slovenia) and Veria (Greece) are the PULMAN partners who will make the 'bridge' with PULMAN-XT.
Although this ambitious work programme is consuming a great deal of the time of PULMAN Network members, thoughts are already beginning to turn to what comes next. How can the important resources created by PULMAN, such as the Guidelines, the training resources and the political work, be sustained once the EC-funded period is over? How best can the cross-domain agenda for local services in cultural heritage, learning, employment skills, etc. best be developed under IST in future and how might the PULMAN Network contribute? We are working on it!

By Ziga Turk, Bo-Christer Björk and Bob Martens - July 2002
Ziga Turk, Bo-Christer Björk and Bob Martens provide a very telling insight into current practices in the relationship between publicly funded researchers and the commercial scientific publishing industry. They see the existing situation as quite unsatisfactory and an obstacle to the efficient exchange of research information and hence scientific progress. They explain for us how the SciX Project intends to redress, what appears to them, to be a very unacceptable state of affairs.

| Figure 1: Cover page of the Philosophical Transactions |
The history of scientific publishing starts in the 17th Century when the Royal Society created the Philosophical Transactions of the Royal Society of London [1]. The intention was to create a public registry of ideas - a logbook or journal - of the "present undertakings, studies and labours of the ingenious" who thought of what first - to protect intellectual property and ensure the rapid evolution of scientific knowledge (Fig. 1). For a long time, scientific publishing remained largely in the hands of learned societies and similar scientist-driven institutions. Publishers have been entering the market since the mid-19th Century, but their role was marginal and profits negligible until the 1960's, when the Science Citation Index [2] was introduced and the number of Universities around the developed world grew quickly. "What librarians (of these Universities) viewed as crucial core journals, publishers translated as the constitutive elements of an "inelastic market", i.e. a market where demand was little affected by pricing (and vice versa)" [1].
The business model of publishers is a fascinating one. The scientists do the research, they write the papers, they review their peers' work and they edit the scientific journals. They give away the copyright to their work, for free, to a party that has not been taking part in the value chain before. They then subscribe to, usually, rather expensive journals, so that they can learn about the work of their peers. In the SciX project we believe that giving away the right to copy (copyright) and distribute results of scientific work hinders the efficient exchange of information and makes scientific results harder and more expensive to obtain.
This belief is the baseline of the SciX project [3]. SciX (Open, self-managed platform for scientific information exchange - IST - 2001 - 33127) is a 24-month project with EU funding of Euros 1,000,000. Co-ordinated by the University of Ljubljana (Slovenia), the partners include Swedish Business School of Finland, Icelandic Building Research Institute, an eBusiness company Indra/Atlante (Spain), Technical University of Vienna (Austria), FGG Institute (Slovenia) and the University of Salford (UK).
The partners have been active in the field of electronic publishing since the mid-1990's. Bo-Christer Björk and Ziga Turk have been the editor and one of the co-editors of the Electronic Journal of Information Technology in Construction [4]. The average time from submission of a paper to its publication has been around 6 months. With each paper published there were on average about 1,000 readers who viewed the abstract and about 1,400 who downloaded the full text.
Since 1999, Bob Martens and Ziga Turk have been managing CUMINCAD - the Cumulative index of CAD [5] - the largest freely available database of papers related to computer aided architectural design (CAAD), particularly related to education in this area. At conferences organised by regional organisations of CAAD teachers (ECAADE in Europe, ACADIA in North America, Sigradi in South America and CAADRIA in Australasia) thousands of papers have been published. Rarely were the proceedings published by a professional publisher. Therefore the texts were not entered into commercial indexes and neither were they sold commercially. The full texts were not broadly available; only conference attendees had copies. On the other hand, the professional organisations retained the copyright to this work and could therefore allow its publication/archiving in the CUMINCAD. Accordingly this work is available on the Internet and rescued from oblivion. At the time of writing, CUMINCAD comprises 3,831 papers with abstracts. 883 papers are also available in full text.
 |

| Figure 3: CUMINCAD database search results page |
Both professional organisations and groups of publishers, as well as specialised companies, are providing added value services related to scientific publishing. One example, amongst others, is the CIB's database ICONDA. Several bibliographical databases provide sophisticated search engines on bibliographic information about publications, (furnishing details such as titles and abstracts). Full texts are, as a rule, not available.
| Ei Compendex | ICONDA | RSWB | CumInCAD | CiteSeer | |

| Number of records | 6.000.000 | 500.000 | 575.000 | 3.000 | 2.500.000 |
| Availability | $ | $ | $ | Free | Free |
The Internet represents a threat to traditional publishers. While some years ago, the Internet was a first resource for obtaining scientific information [6], today it is becoming the only resource, particularly with young researchers. Traditional publishers are responding with services such as ScienceDirect which allows pay-on-demand access to the full texts of published papers.
Another strategy of publishers is to avoid dealing directly with the readers of journals and attempting to negotiate direct, long-term deals with either whole universities [7], or whole countries [8]. Although discounts are offered if an institution subscribes to a full spectrum of journals, the economies of such deals for the funding bodies and the researchers are not necessarily positive.
The idea to use the Internet for scientific publication is not new. Existing solutions are of the following types:
Problems with these services include:
The policy of the ARPA (Advanced Research Projects Agency) and the NSF (National Science Foundation) in the United States was that all research that was funded through public funding should make the results available for free. This has not been entirely true of published papers, but has worked excellently with software. Programs written in the context of research projects were made available - for free, usually including source code - on the Internet. In fact, the software to run the Internet in the first place was available for free. This created the critical mass for the so-called open-source initiative [12]. An increasing number of operating systems, application programs and tools are available free. Market share of those systems is growing and they are being used as a platform for vertical applications by companies such as IBM.
On the other hand, the European-funded research projects (such as the 4th and 5th Framework projects) have never required that results be made publicly available. The excuse offered was that commercial companies are co-funding this work and that they are not interested in making available what could be their competitive advantage. We are not aware of the scientific community challenging this system. Labelling most of the reports "restricted" actually restricted the readership to the project officers and the reviewers.
Standards organizations, in common with journal publishers, do not fund the writing of new standards, yet they are given the copyright of a standard. They support their organisational activities by the sale of the paper copies of those standards. Several research efforts addressing the computerisation of building codes stopped at a prototype level, because of problems with the copyright to the text of the standard.
The standards that govern the Internet and the Web serve as something of contrast. The well known "request for comments" documents (RFC's) are the result of the work of groups of individuals and are made available, for free, on the Internet, to be commented on as well as for writing compatible software. One may recall that in the early 1990's there was direct competition between ISO- and Internet-based networking, best exemplified by the use of two different email addressing schemes. The Internet solution, based on open freely accessible standard RFC822, prevailed.
The development of product modelling standards also started with the restricted publication model. Only recently has the IAI (Industry Alliance for Interoperability) corrected this mistake and is making the entire IFC (Industry Foundation Classes) standard available on the Internet for free.
In the paper-based publishing, a few dozens publishers control most scientific publications. Making a reasonably complete index involves including the publications of those few largest publishing organisations. If, however, thousands of people start creating digital archives on the Internet, indexing that information could be quite challenging. Web search engines, such as Google or Altavista are not very appropriate tools for searching for scientific information, because they index everything indiscriminately.
The Open Archives Initiative [13] is standardising the metadata structure and the API of an archive, so that the archive can be indexed and so ensure that several archives can be searched by users at the same time. Moreover, Open Archives Initiative is developing standards that aim to facilitate the efficient dissemination of content.
The objective of this project is to demonstrate
2-4% of European GDP (Gross Domestic Product) is spent on research and development - on creating new knowledge. While several projects deal with the management of knowledge that is created within industry, little has changed in the past hundred years in the ways that knowledge, created by scientific research and published in scientific journals, is handled. The current mainstream scientific publication process has so far been only marginally affected by the possibilities offered by the Internet, despite some pioneering endeavours. This is not so much because of lack of enthusiasm, but because there is a lack of sound business models and pilots to demonstrate the benefits of totally free scientific archives to the organisations, which, ultimately, should be funding their development and maintenance.
The objectives of the Project are:
To achieve these objectives SciX will:
Most technologies and software to implement these goals are either freely available or have even been developed by the partners in this project in the past. See section "Previous work".
The main problem in a new vision of information exchange in science is the copyright that researchers currently give away to the commercial publishers for free, and which results in severe obstacles for potential readers in retrieving the information they need. There are also other barriers to a shift to free repositories such as addressing the perceived risks of Internet publishing, the sluggishness of academic departments in changing their "rating" systems, etc., all which need to be studied. A survey we conducted in the year 2000 in the field of construction IT and management showed interesting results in relation to what scientists think about where to publish and what to read. We intend to continue this survey over the next years so that the trends can be monitored as well as gauging the impact of the proposed repository.
Typically scientific journals have been rated by prestige, often based on subjective evaluations or, to some extent, on the use of citation indexes. Ratings have been done implicitly through university departments, for instance in shortlists of accepted publications for promotion etc. Little attention has been paid to questions of how quickly and efficiently the information passes to experts for whom the information could be useful. Thus it would be very beneficial to develop methods which would allow the benchmarking of journals for factors other than the scientific quality of papers (e.g. turnaround time from submission to publication, availability, readership etc.). Such a benchmarking tool will be developed in the project and tested with a number of journals from different categories. The main value of such a tool would be as a means to increasing the awareness within scientific communities of the deficiencies of their current communication process. It is to be hoped such awareness will trigger action towards altering the process.
The main components of the demonstrator comprise:
Open source solutions and/or rentable Web infrastructure will be created and made available to potential users. Compatibility with emerging standards, such as Open archives, will be incorporated.
The SciX project started in February 2002. Current work includes the analysis of user requirements , design of the overall architecture and the business process modeling of the as-is situation. First deliverables are due in September 2002.
This article appears under the auspices of the SciX Project [3], funded by the European Commission under contract IST - 2001 - 33127. The contribution of the funding agency as well as that of industrial partners in the project is gratefully acknowledged.

By Panos E. Trahanias - July 2002
If, like me, you were unsure of the meaning of "avatar" outside the science fiction novels of Ian M. Banks, then Panos E. Trahanias sheds light upon its uses in this article. He writes of the achievements of a project which developed a way to provide remote users with a tele-presence in museums in the sturdy shape of TOURBOT.
[Editor's note : "avatar n. Computing: a movable icon representing a person in cyberspace or virtual reality graphics" (Concise Oxford Dictionary)]

The Internet is a fast evolving technology that electronically connects distant sites; however, up to now, electronic networks serve mainly to exchange and acquire information. In some cases this information is pictorial, often gathered by means of images taken in "real time" with a stationary Web-camera. To take full advantage of a network, such as the Internet, it would be desirable to get real physical interaction with the remote site being visited. Robots, and especially mobile platforms, can extend the Internet towards an interactive platform that allows actions to be carried out and dynamic information to be exchanged between distant sites. The TOURBOT project implements exactly the above concept for the particular case of museums as remote sites.
TOURBOT, the acronym of a project entitled "Interactive Museum Tele-presence Through Robotic Avatars", consisted of a research and technological development activity funded by the Information Society Technologies (IST) Programme of the European Commission. TOURBOT commenced January 2000 and ended successfully February 2002. The goal set forth in this project was the development of alternative ways of achieving interactive museum tele-presence, employing the novel approach of site viewing through the 'eyes' of robotic avatars [1-4]. This was accomplished and demonstrated in relevant events in real museum environments.

| Figure 1 : Tourbot meets the press | Figure 2: TOURBOT with young visitors |
The TOURBOT Project was carried out by a consortium that comprised an ideal blend of technical partners (Foundation for Research and Technology - Hellas, Greece; University of Freiburg, Germany; University of Bonn, Germany; THEON Mobile Platforms, Greece), brokers of technology to museums (Foundation of the Hellenic World, Greece), and end users (Foundation of the Hellenic World, Greece; Deutsches Museum Bonn, Germany; Byzantine and Christian Museum of Athens, Greece).
The goal of this project was the development of an interactive TOUr-guide RoBOT (TOURBOT) able to provide individual access to museums' exhibits and cultural heritage over the Internet. TOURBOT operates as the user's avatar in a museum by accepting commands over the Web that direct it to move in its workspace and visit specific exhibits. The communication network is, thus, effectively extended by the introduction of interactive, mobile robotic platforms as terminal nodes. The imaged scene of the museum and the exhibits is communicated over the Internet to a remote visitor. As a result the user enjoys a personalised tele-presence in the museum, being able to choose the exhibits to visit, as well as the preferred viewing conditions (point of view, distance from the exhibit, resolution, etc.). At the same time, TOURBOT is able to guide on-site museum visitors providing either group or personalised tours.
To make the TOURBOT system possible, a multimedia Web interface allows people to interact with the tour-guide system over the Internet [5]. Furthermore, an on-board interface facilitates interaction with on-site visitors of the museum. Using the Web interface, people all over the world are able to tele-control the robot and to specify target positions for the TOURBOT system. The robotic tour-guide possesses a multimedia information base providing a wide range of information about the exhibition at various levels of detail. Thus, the TOURBOT system serves as an interactive and remotely controllable tour-guide, which provides personalised access to exhibits with a large amount of additional information.

A tele-operated tour-guide robot requires a high degree of autonomy since it operates in a populated environment in which humans are also present. Therefore, the project included the development of a safe and reliable navigation system for TOURBOT [6-7]. The robotic avatar is equipped with a series of state-of-the-art sensors that allow it to acquire information about its environment. The navigation system uses this sensory information to adapt the robot's internal model of the environment and to plan the robot actions.
The TOURBOT project introduces a new paradigm in providing access to cultural heritage exhibits [8]. Through the introduction of museum visiting via a robotic avatar, it facilitates immersive tele-presence with advanced visualization capabilities. Full access to cultural exhibits is granted to the user, in the sense that the latter is able to choose the exhibits to visit, as well as the preferred viewing configurations. The approach employed in the current project introduces a novel model of augmented environments, in that it allows human interaction with, and workspace exploration of, remote sites by means of a robotic avatar.
As a service to remote users, TOURBOT extends current communication networks by allowing mobile robots to be part of the overall structure. Such a mobile agent acts as the user's avatar, operating in a physical environment that is perceived by the user through the robot's sensors. Therefore, the TOURBOT results contribute towards the seamless integration of networks and mobile agents for providing full user access to exhibitions.
Tourbot has achieved its RTD goals and has undertaken demonstration trials in the premises of the participating museums. More specifically, the TOURBOT system has been developed and fully tested in laboratory environment. Following that, and in order to acquire performance data from actual museum visitors, the system has been installed and demonstrated in the three museums of the Tourbot consortium. These demonstrations were combined with relevant events in order to publicise and disseminate the results of the project to professionals and the broader public. Details of these events are as follows:

By John Counsell - July 2002
John Counsell reports on the Valhalla project, which aims to provide in-depth comparative historic garden information, linking Hatfield House in Hertfordshire with the Château de Villandry on the Loire in France. Researchers have installed digital video cameras overlooking the grounds, sending real-time images to local servers and onto the Web. Staff program the cameras from Bristol, allowing them to zoom in, script identical film sequences, or set up video conferencing sessions between garden staff at the two locations.

This article provides an overview of the first months of the Valhalla Project, which links historic garden records with real-time video on the Web. Visiting historic gardens attracts huge public interest, combining as it does twin passions for gardening and history. Many enthusiasts are interested in being able to compare historic gardens, learn how they were designed, how the plants were chosen, and the way in which they change with the seasons. Thompson said of historic ruins that:"the best basis for understanding a ruin is therefore a wide knowledge of structures of the same period, whether ruined or not, since the mind is consciously or unconsciously making comparisons, and the larger the stock upon which it is possible to draw, the more reliable the result is likely to be." [1]. This project is based on the assumption that the need for comparative understanding is as true for historic landscapes and gardens as for buildings, that many cannot travel extensively enough to gain this broad-based understanding, and that now virtual travel on the Web can provide an effective substitute.

The Valhalla project, led by staff at the University of the West of England, Bristol (UWE), aims to provide just such in-depth comparative information, by linking the gardens of Hatfield House in Hertfordshire, with the Château de Villandry on the Loire in France. Researchers from the University's Faculty of the Built Environment have installed digital video cameras high up on the buildings, overlooking the grounds, sending a continuous stream of images to local servers and onto the Web. UWE staff program the cameras from Bristol, allowing them to zoom in, script identical film sequences, or set up video conferencing sessions between garden staff at the two locations.
Web-based images will allow people who are unable to travel to enjoy the gardens in all their glory. Visitors to either attraction will be able to see what is happening at the other site, and can also see archived film to find out what the gardens look like at other seasons of the year. Records of the plants and trees and their positions could also have long term benefits for curators, since it has been found that many gardens do not have adequate records to assist accurate reconstruction, and yet are at risk, as shown by the great storms of recent years.
|
| Figure 3: Current draft webmap video control |
The Valhalla project is a continuation of previous work at UWE in linked VRML (Virtual Reality Modelling Language) and spatial databases, applied to visitor information and heritage site management. It extends the previous work in two directions, that of real-time remotely controlled acquisition of digital imagery, and that of the relationship of heterogeneous information to the images to explain and interpret them based on VRML, the whole managed and updated from a Geographic Information System (GIS). The GIS used is Mapinfo, and the VRML is output by a program called Pavan [2]. The project runs from October 2001 to September 2002, funded by the European Commission Information Society Technologies programme (IST-2000-28541). It is a partnership between UWE, the Gardeners Exchange Trust (who have promoted physical exchanges between European historic gardens staff over the last few years), and the twinned gardens of Hatfield House in the UK, and the Château de Villandry in France.
The goal is to promote comparative study and discussion between staff at each site (a virtual Gardeners Exchange), and put real-time interpretative samples on the Web, with 'hot-spot' information generated in matching VRML viewpoints from a 3D spatial information system. This involves a form of remote data capture, followed by spatial referencing and retrieval of digital images with other associated descriptive information. The project team has therefore installed remotely controlled video cameras in prominent positions overlooking the gardens. Staff may control the cameras during interactive on-line discussion to illustrate or seek information, or the cameras may follow scripted routines to capture matching images for later time-lapsed sequences showing diurnal and seasonal change.
There are thus six major elements to the project:
Recording information on the gardens took more time than planned due to the lack of useable surveys or planting plans. Geometrical measured surveys have been completed of the selected area of each garden in the field of view of the cameras and a 1992 survey of Villandry was purchased from a local geometrician. For both gardens the logged data then had to be translated into the Mapinfo GIS (Geographic Information Systems). Steps, walls, copings and other distinctive architectural features, and the edges of changes in hard and soft landscape surface materials, such as grass, paving, flower borders and paths have been separately identified in the GIS.
Previous experience had shown that even expert horticulturists cannot readily recognise every plant from photographs, and want to examine the leaves and flowers and form of the real plant. It became apparent that a separate process was necessary to log information about the plants visible within the video images. Thus the purpose of the geometric surveys was to 'map' locational information about plants, trees and hard landscape features within the field of view of each camera, into the GIS from which the VRML (Virtual Reality Modelling Language) 3D Web-based models are generated. Hyperlinked pages of plant information are generated from the GIS attached to the 3D elements in the VRML model. The same instructions used to control the video camera are to be used to instruct the VRML model to show the same view, in a companion frame to the video image. Clicking on elements in the model enables comparative identification of the elements visible in the video. (Common plant names in French and English are linked by the Latin name as a key to assist identification despite the different languages involved).
Compaq IPAQs were acquired for the task of hand-held plant data logging at each site, with ESRI Arcpad GIS software (on investigation found more usable than the comparable Mapinfo pocket PC product). These have both wireless networking connection and docking station transfer of data to and from the server. The Arcpad software has been loaded with spatial mapping of both gardens and with templates developed for logging the location, characteristics, and spread at different seasons of each distinctive plant feature. GIS standards for exchange are robust enough for it to be simple to exchange mapping and data between Arcpad on the IPAQ (or Desktop) and Mapinfo at UWE. However garden staff have proved reluctant to embrace technology to this extent, and have been more comfortable with paper based maps and forms, from which the data has been transcribed onto computer later.
Gardens were chosen that are designed to be seen from the windows of the House, so that a camera mounted on the house as a vantage point would give a similar view. Both a fixed and a motorised camera were installed because there was no suitable position from which the whole of the selected area at either garden could be viewed by a single camera. Initially it was intended to install a conventional pan and tilt motorised camera mounting with a Sony FCBIX47 Camera (460 TV Lines) with auto focus and 18 times optical zoom, in a heated weatherproof housing. However on investigation and testing, it became apparent that the conventional motorised mountings used in the security industry are only suitable for a limited range of preset views or for direct control by keypad and joystick by an on-site operator; they do not enable the precise telemetry required for remote control over the Web.
 |
| Figure 4: Dome Camera at Hatfield House |
It was found that the Dome Camera (Dennard 2050) was capable of precise telemetry, but would require programs to be written to control the camera remotely. Unfortunately the dome camera is more prone to reflection, glare and raindrop distortion. A C program was written and tested by Oggle Ltd, from whom the cameras and Web upload utilities have been leased, to control the dome cameras. Shell scripts were developed by UWE to enable the cameras to be remotely controlled by clicking on a map or panoramic image on a Web page, with a slider to control zoom. These now work effectively.
The Parallelgraphics Software Development Kit was bought in order to customise and simplify the Cortona VRML browser to display modelling in conjunction with video clips. A 'calendar' program has been written by UWE to control the cameras based on the data in the Mapinfo GIS, and simultaneously archive the video clips tagged with data on viewpoint and zoom. The program calculates and exports field of view and directional vector data from the GIS, (based on optimal viewing times and locations for features within the spatial database), to prepare scripted directional information to control the path and field of view of the video camera. The same program responds to date-time triggers tagged onto plants and objects in the GIS to operate the Mpeg2 capture card (to avoid over-filling the local server hard drive) and write the results (tagged with viewpoint data) to DVD for transfer back to UWE. This program records vector and field of view metadata with each image file to enable video sequences to be selectively archived with associated VRML seasonal modelling.
|
| Figure 5: Draft Villandry model VRML with plant data |
A search program will use the metadata to invoke an archived video clip and a matching VRML model view. This helps to address the issue of data management of potentially very large quantities of images: partially by planned 'scripting' to capture in a selective manner; but also by use of the GIS to assist in 'automated' content description, management, archival storage and retrieval by place, time, and objects within the field of view. The calendar and search program will upload both seasonal VRML models and matching movies to the Web. Previous experience has shown the models work well to invoke Web pages of information.
A Web Site was created [3] for public information about the project on a server at UWE, with threaded discussion forum, whilst links to the video footage and the VRML modelling are being added as they became available. The video cameras are linked to a specialist compression card (from a French company Com1) incorporated in a Linux Web server on each site, which serves the images in 640 by 480 resolution motion JPEG format on the Web via ADSL or ISDN, and archives the video in clips, currently set at 5 minute intervals throughout the day. (The archived clips are transferred nightly to a server at UWE, Bristol to avoid limiting bandwidth during the day.) The remote location of servers and cameras in the unused wing of the Chateau also required the installation of a wireless Ethernet bridge to connect the servers (and cameras) to the Local Area Network in the separate administration building approximately 100 metres away, and thence to the ISDN router.
The Web-based interpretative real-time samples and archived or time lapsed sequences linked to matching 3D model views are intended to enable the comparative study of similar information within both gardens from a Web browser, so broadening public access to this aspect of European cultural heritage.
This is designed to:
Spatial extensions to SQL with active server pages are to be developed to make available Web-based template search routines to serve bespoke images or maps of the gardens in printable Web pages. The extent of accessibility of routes is to be colour coded in both map views and VRML models. Video clips, walking through the gardens, have been taken to supplement and enhance the aerial real-time views, and historic images are being incorporated at both sites, using the VRML model to fade from matching existing image to historic image and vice versa. Active server page scripts, and cookies generating questionnaires to frequent users, will audit visitor use of the Web site at the garden or on the Web.
Expertise from professional gardeners for display on the World Wide Web will be added by:
The cameras generate higher quality video than can be seen currently on the Web. The additional occasional upload of high quality Mpeg2 (approximately 45 m/bytes for 1 minute) is possible but cannot be relied on. Transferring the archive of Web Video Clips per night is approximately 500 - 600 m/bytes per day for the two cameras on each site, which takes about 5.25 hours at 256 kb/s upload (the ADSL at Hatfield), and twice as long for the 128 kb/s upload (ISDN at Villandry). It proved necessary therefore to write scripts to record the Mpeg2 in real-time on site, archive it onto rewritable DVDs on site and then send the DVDs by post to UWE for editing and archive. The calendar program also handles this. Therefore a second server (running Windows 2000) has been installed at both Hatfield and Villandry and linked to a splitter in the feed from the cameras. This server incorporates a specialist Amber Video card which encodes analogue video in real- time into Mpeg2 format, and a Pioneer DVD recorder. Windows 2000 terminal services are used to remotely control the server, the Mpeg2 card, the DVD recorder, and the Hard Disc space, from UWE, Bristol. This process has been tested through and found to work effectively.
Phillips USB Video cameras and software (Net-Meeting and Yahoo) have been tested and installed, to enable staff to videoconference between the two gardens to exchange knowledge and skill, while reviewing real-time video imagery of selected aspects of the gardens. It has taken longer than anticipated to reach the point where staff can deploy the remotely controlled camera during discussion, due to the difficulties in achieving Web-based camera control discussed above. However the scripts have now been developed and this phase is just commencing.

I have described an investigation into the marriage of long-term data with what might be called more ephemeral imaging data, using a common key of spatial and temporal location, and served by a spatial information system or GIS, to create a meaningful whole. The physical and historical complexity of heritage sites is held to be better recorded and displayed in 3D than 2D, to ensure commonality of understanding between all those involved in its care and with the wider public who fund it. However, in order to enable common retrieval, much more locational and time data needs to be captured and entered into a database with visual images and information than is currently the norm. A common approach to spatial and temporal referencing across a range of sites will enable comparative search and simultaneous display to envision the broad range of examples that Thompson described as so important to enable reliable understanding of what is seen on site. This broad understanding can only be obtained asynchronously by first hand experience at present.
The Grand Canyon is cited in support of the argument that some sites need no interpretation, although this is not held to preclude the need for informed professional understanding [4]. The Grand Canyon might be brought to a remote off-site audience using video and audio alone. However many other sites are enhanced by interpretation and for these remote access or, in the future, augmentation of the reality on site will require on-tap synchronised abstract information in addition to that directed at the senses. It takes a long time to commission and procure useful records. To meet these future developments it is desirable to record locational and temporal metadata with such records now. The Valhalla project suggests that this can be done, and that the process can be made resource effective, by enabling public access to the information gathered in interactive and interesting ways.

By Paul Miller, David Dawson and John Perkins - July 2002
Paul Miller, David Dawson and John Perkins report on the second in a series of international meetings at which representatives of cultural content creation programmes from around the world work towards greater collaboration.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
As reported in issue 5 of Cultivate Interactive [1], there is increasing evidence of broadly similar approaches to the digitisation of cultural content being adopted in countries around the world. In an initiative to ensure interoperability of approach wherever possible, effort is being devoted to opening and maintaining communication between the various programmes, and to exploring scope for collaborative working and standard setting. Following an initial meeting in London during the summer of 2001, some 40 representatives of various cultural content creation programmes gathered in Washington, D.C., in March of 2002, as guests of the US Federal Institute for Museum and Library Services (IMLS).
A number of clear themes emerged from the meeting, building upon those already identified in London. Clearest of these was a recognition of the importance of gaining a far better understanding of our users, the uses they make of digitised cultural content, and their requirements around the creation of new content. There was also a high degree of interest in the Open Archives Initiative (OAI), and in the various testbeds already underway or shortly to commence amongst several of those represented. Work on these and other activities is now moving forward, both bilaterally between specific initiatives, and in concert under the umbrella of a new digital Cultural Content Forum.
There has been a great deal of effort expended in recent years in digitising a wealth of cultural content for display on the Web. The reasons for digitising this material range from preservation to education, but relatively little effort has been devoted to understanding what users actually want from content, or the uses to which they wish to put it. There are notable exceptions to this apparent lack of interest, but the broad trend is unfortunately one, to paraphrase, of building it, safe in the knowledge that 'they' will come (and, presumably, enjoy, tell their friends, and come again!) Although visitor numbers for many cultural sites on the Internet are certainly highly satisfactory, comparing them to the far larger community of potential users suggests that more users await awareness raising activity or some suitable enticement. There is also largely unquantified work to be done in improving the experience for those who actually do visit, and in delivering the content and services that the user seeks, rather than expecting them to be satisfied with that which the content provider has selected on their behalf.
The work to be done in this area is potentially costly and long-term, but those gathered in Washington were unanimous in agreeing that the sector requires far better understanding of the issues, and of information that is already available. As such, a brief is being developed for a focussed piece of work, in which existing studies of user experiences and requirements for digital cultural content - both commercially sensitive and already in the public domain - will be located and synthesised in order to identify broad trends and issues. This work will serve, we believe, to identify knowledge which already exists within memory institutions in isolated pockets. It will also serve to generate both hypotheses for testing and flag up questions in need of asking through further consultative work, whether conducted collaboratively or at a local level by individual institutions and agencies.
Since first announced, there has been significant interest in the work of the Open Archives Initiative [2]. This interest has arisen both for associations with potentially radical changes in the manner in which scholarly research is published and disseminated, but also for the technical work around a Protocol for Metadata Harvesting [3]. This protocol extends beyond the confines of scholarly publishing and e-Prints. It offers capabilities for software to 'harvest' basic Dublin Core [4] records describing content in a wide variety of forms and formats, and to create large repositories of metadata suitable for integration and manipulation in a range of ways. In the UK, for example, an evolving Architecture [5] for the JISC's Information Environment [6] recognises the key role of such harvesting in the distributed information landscape, alongside searching remote databases and alerting both human and machine users to changes in content.
Amongst memory institutions and related bodies, there has been a great deal of interest, and a number of programmes are currently getting underway to explore the realities of creating, maintaining and making use of these repositories of metadata, and the services likely to grow up around them. The JISC's FAIR Programme [7], a number of Mellon projects [8], and an RfP from IMLS are amongst a raft of funded explorations of the technology and the issues of integrating it with existing practice.
Participants expressed interest in learning more about the potential of OAI and other 'new' technologies to assist them in delivering on their missions, and it was agreed that it might be useful to explore in detail the known work on OAI within the community at the next meeting. Stronger bridges were also built between a number of the funded programmes exploring this technology, and there is the potential for some synergistic work to emerge, rather than a number of wholly separate programmes.
This meeting, possibly more than that in London, emphasised some of the very real differences in approach across the jurisdictions represented, whether in terms of the reasons for digitising content in the first place (lifelong learning, national identity, tourism, digital librarianship, etc.), or the roles expected of public, private, and quasi-public bodies within the process.
Despite these differences, there remain clear advantages in ensuring effective lines of communication across national and disciplinary borders, and the group was felt to play an important role in maintaining this dialogue due to its broad (and growing) international make-up, and its mix of funders, policy makers and strategists.
In order to form a focus for this work to progress, the group is to become the digital Cultural Content Forum, and work is currently underway on a Web site [9] and a series of associated documents for this group in order to raise its profile and create an environment in which issues of import may be progressed.
Notice of public deliverables from this group, including the launch of the
new digital Cultural Content Forum Web site, will be given via e-mail to various
community mailing lists. Those who are interested in receiving notification of
all such deliverables are invited to join the public mailing list,
interoperability, hosted by the UK JISCmail service.

Brian Kelly reviews the CULTIVATE National Node Web sites using a variety of automated tools, and makes some comparisons with a survey of National Focal Point Web sites.

The CULTIVATE project [1] (of which the Cultivate Interactive e-journal is a part) supports the dissemination of information about the EU's Digital Heritage and Cultural Content (DIGICULT) programme [2]. National Nodes have a key role to play in the project by disseminating information within their own country. As well as organising meetings and events, giving presentations and running mailing lists the National Notes also provide Web sites to support their dissemination function. The National Node Web sites complement the work of the the central CULTIVATE Web site [3] by providing regional information and by providing information in the national language(s).
The work of the National Nodes has built on the work of the National Focal Points (NFPs) which were funded by the EU's Fourth Framework's Telematics For Libraries programme. The work was coordinated as part of the EXPLOIT project [4].
A survey of the NFP Web sites was published in Exploit Interactive in October 1999 [5]. The survey showed that a variety of approaches to the provision of Web sites was taken. There was no consistent visual identity or navigational aids and it appeared that there was little sharing of information on best practices.
In the CULTIVATE project it was agreed to address some of these limitations by making use of a consistent visual identity and navigational structure and, through regular meetings and email communications, provide support and advice in implementing best practices.
In this article a summary of a survey of the National Node Web sites is given.
The analysis of National Node Web sites makes use of the central list of National Nodes maintained on the central CULTIVATE Web site [6].
It should be noted that this list includes information on National Nodes funded by the CULTIVATE-EU (for EU countries) and CULTIVATE-CEE (for Central and Eastern Europe Countries), together with the recently established CULTIVATE-Russia project.
Of the 26 countries listed 22 provide a National Node Web site. Details of the Web sites' address are given below.
As can be seen from Table 1, 11 Web sites have an entry point of the form <www.country_code.cultivate-europe.org>. This can be compared with the findings for NFP Web sites, for which there was no consistency and the address of other Web sites could be be extrapolated from knowing the address of one.
A total of 14 Web sites make use of a simple domain name, with no additional path name required. This compares with NFP Web sites, in which only two countries made use of a domain name as the entry point. Use of a simple domain name means the URL is easier to type, is more memorable and can be more easily marketed.
Many of the Web sites have made use of the CULTIVATE visual identity and look-and-feel, as can be seen from Figure 1.

| Figure 1: The Irish and Estonian National Node Web Sites |
As well as helping in raising awareness of the CULTIVATE project, consistent use of the visual identity and look-and-feel will also be helpful for end users who may have an interest in accessing more than one National Node Web site.
A "Web tour" of the National Node Web sites is available [7]. This provides an automated display of the the entry points.
Netcraft [8] was employed to analyse the server technology used to provide the National Node Web sites. A summary of the findings is given in Appendix 1.
Thirteen of the Web sites are (probably) hosted on a Unix server and 9 on an Windows NT server. Interestingly, in addition, one Web site appear to use the Microsoft server software on a Unix platform.
As well as helping in raising awareness of the CULTIVATE project, consistent use of the visual identity and look-and-feel will also be helpful for end users who may have an interest in accessing more than one National Node Web site.
A "Web tour" of the National Node Web sites is available [7]. This provides an automated display of the the entry points.
AltaVista [9] was used to provide information on the numbers of pages indexed by AltaVista and the number of links to the National Node Web sites. A summary of the findings is given in Appendix 1.
It should be noted that the information on the number of links is taken from the AltaVista database. It cannot be guaranteed that the information held on the database is complete.
NetMechanic [10] was used to analyse the quality of the National Node home pages. This included reporting the numbers of broken links and HTML errors on the page and the load time for the page. A summary of the findings is given in Appendix 1.
From the findings it will be noted that several of the Web sites appeared to contain broken links and HTML and browser compatibility errors. In some cases this was not actually the case - NetMechanic may sometimes provide incorrect results. However in a number of cases there were problems with the pages.
The Robot Exclusion Protocol [11] enables a Web site administrator to specify directories which robots should not access. Although it does not provide a security mechanism this protocol can be used to avoid search engines indexing draft documents and personal files. It can also be used to stop search engines from wasting server capacity by attempting to index files such as images, CGI scripts, etc.
A brief summary of the use of the Robot Exclusion Protocol for the National Node Web sites is given in Appendix 1.
It was noted that none of the Web sites appeared to support the Robot Exclusion Protocol. This may not be an issue, as it is likely that National Nodes will want all pages on their Web sites to be indexed by robots.
The 404 error page is displayed when a URL is given for a resource which does not exist. This may be due to an incorrect URL being contained in a HTML page, a page being moved or deleted or the end user typing in an incorrect URL.
A brief summary of the 404 error pages for the National Node Web sites is given in Appendix 1.
It is possible for the 404 error page to be branded with the Web site's visual identity. The 404 error page can also provide useful additional functionality, such as providing a search facility. However it was noted that none of the National Node Web sites provides branding or extra functionality on the 404 page.
The Bobby tool [12] was used to analyse the accessibility of the main entry point for National Node Web sites. The results are given in Appendix 1.
It was noted that a number of the National Node Web sites contained P1 errors.
A summary of the search facility provided on National Node Web sites is given below.
The following Web sites provided a search facility: Austria, Czech Republic, Denmark, Estonia, Finland, Hungary, Ireland, Latvia, Lithuania, Norway, Russia, Slovenia and the UK. This is a total of 13 of the 21 Web sites.
In order to establish how easy it was to find the CULTIVATE National Node Web sites using a search engine Google was used to search for "Cultivate country" where country was replaced by the English spelling of the country. The results are given in Appendix 2.
It is pleasing to report that for all of the countries the National Node Web site, the central CULTIVATE Web site or the Cultivate Interactive e-journal was found in the first page of the results for all Web sites, in numbers ranging from the first 4 results to all 10 results on the first page provided by Google! These findings are even more impressive if one takes into account the fact that the search term is in English and not in the country's native language.
Based on these findings the following recommendations are made:
The analysis of the National Node Web sites has shown that many improvements have been made in comparison with the approaches taken in providing Web sites for the National Focal Points. The CULTIVATE project itself has benefited from the consistent approaches which have been made. It is especially pleasing to discover that a search for the term "cultivate" (a widely used word) obtains so many hits from the Google search engine, and that a search for this term in conjunction with the country name will also provide relevant information for all countries. The CULTIVATE name is clearly a valuable asset to the project (and the European Commission itself).
Although the National Node Web sites are clearly search engine-friendly, the survey has identified a number of areas in which minor modifications to the Web sites should be made in order to improve the Web sites accessibility and interoperability. It is hoped that this survey has helped in identifying these areas, and that the tools which are accessible from this article will be used by the National Nodes both to enhance their Web sites and to examine other National Node Web sites in order to make use of best practices.

This section aims to provide news of the European Commission's initiatives in the field of digital heritage and cultural content. Its objectives are to pinpoint the latest developments in programmes, projects and activities and to give a clear picture of progress in the area since the last issue. It certainly does not pretend to be a comprehensive account of what the EC is doing in the area but rather a short summary of some of the key items. The content is based largely on the information provided in the eCulture Newsletter [1], published by the European Commission, DG Information Society, Cultural Heritage Applications Unit [2].

Since the last column in February, a number of important conferences have taken place, two of which we would like to highlight:
This conference, which was supported by the EVAN (Electronic Imaging and The Visual Arts Networking) European Project, was preceded by two days of training activities and Workshops [3].
The main EVA Conference saw the presentation of 55 papers and two important special sessions: one devoted to the 6th Framework Programme plans of the European Commission (2003-2006), presented by Bernard Smith. The other, organised by TRIS, was given over to the presentation of 17 Projects (TRIALS) launched as a result of the 4th IST Programme of the European Commission in 2000.
Several outcomes from the EVA 2002 Florence conference were forthcoming:
This conference was held within the framework provided by the Lund Action Plan. The Lund Principles [4] cover the tasks needed to co-ordinate Member State digitisation programmes. The associated action plan requires the establishment of a National Representative Group (NRG)[5]. This group is formed by representatives and experts nominated by Member States, in many cases from national cultural institutions or Ministries of Culture. The National Representative Group has Terms of Reference [6] and meets every 6 months under each Council Presidency. The first meeting took place under the Belgian Presidency, and this mission report covered the second meeting hosted by the Spanish Presidency.
The actual NRG meeting took place on the 16th May 2002. The agenda covered:
The meeting on 17th May 2002 was given over to presentations on good practice in Member States (based upon a request by the Spanish Presidency to the NRG group). Spain, Austria, Sweden, Denmark, Portugal, Belgium, France, Germany, UK, and Italy nominated more than 40 best practice projects and made short presentations during the day.
Following these presentations a statement was made by the future Danish Presidency. They indicated continuing support for the work of the NRG and also for the issues of quality (leader Belgium) and long-term digital preservation, (leader Spain with the Council Resolution). The session continued with a more detailed presentation by the Spanish CAC representative on the new Council Resolution on Long-term Digital Preservation.
The next NRG meeting mill take place in Copenhagen on 10-11 December 2002 under the Danish Presidency.
The essential issues were:
The new network MINERVA presented its different objectives and practical tasks. The meeting's conclusions mentioned priorities both for the NRG and MINERVA partners. MINERVA will compile examples of good and best practice into a document for circulation.
The Spanish Presidency presented the Council Resolution on long-term digital preservation. Its cultural priorities had been:
The last point concerns the influence that cultural policies and related activity brings to bear upon other policies of the EU; (to date cultural policies have more been subject to the impact of other EU policies). The need for a "European Cultural Space" was introduced.
Luis Alberto de Cuenca, the Spanish Secretary of State for Culture, concluded that there was a new spirit of cooperation between Member States on digitisation, and that Spain had many excellent on-going projects and was well placed in the EU context. He congratulated all the participants on making the event a success of the Spanish Presidency. His closing speech was followed by a press conference, resulting in several articles being published in Spanish newspapers.
Overall the meeting the meeting proved invaluable in terms of its technical content and its high standards of organisation by the Spanish Presidency were appreciated. The facilities provided by Alicante University were outstanding.
Negotiations are currently ongoing for 7 projects along 3 different action lines:
For "Preparing for future research activities", two Thematic Networks are being set up, "e-Culturnet" and "Orion", and one Accompanying measure, called "First".
Under Action line "Network of excellence and working groups" three projects will probably been taken up -"Pulman", "ART-E-FACT" and "Musicnetwork" (see below), whereas there is only one negotiation under way for "Enabling RTD co-operation with newly associated States" (working title "HEREIN2E")
More detailed information will be available on the CORDIS projects pages [7] as soon as the contracts are finalised.
One of the interesting new projects to emerge from the 8th call is MUSICNETWORK, a network of excellence on music interests across Europe. The main objective is to bring European music industries and content providers together in order to promote interactive multimedia. Special attention will be devoted to interactive coded music - standards, representation, distribution, protection, imaging conversion, etc. The user community will include publishers, multimedia distributors, music shops, schools, music conservatoires, individual consumers and software developers. The project will of course be undertaking state-of-the-art analyses of the technical and content-related aspects. Account will be taken of earlier project work in the field, drawing on the experience of HARMONICA, WEDELMUSIC, MIRACLE and CANTATE. Work is expected to begin in June. Coordination will be by University of Florence DSI, [8].
On 15th May 2002, the European Parliament approved the Council's common position on the Sixth Research Framework Programme to run to 2006 with a budget of some €17.5bn, together with some 34 compromise amendments.
As the new Community Framework (FP6) for research and development introduces important shifts in the approach to EU-funded research, both in terms of content and instruments, the IST programme is organising a series of open workshops in May 2002 [9]. The objectives are to present to the research community the concepts and the details of implementation of IST in FP6, including the new funding instruments and to provide support for partnership building.
The IST priority in FP 6 is an important part of the specific programme on Integrating and Strengthening the European Research Area.
There is further information on the new Framework Programme [10].
The main purpose of IST 2002 [11] is to help build the European Research Area for the Information Society within the EU's Sixth Framework Programme for Research and Development (FP6), which is to be launched at the end of 2002.
To be held in Copenhagen on 4-6 November, IST 2002 will broaden its scope to everyone with a strategic interest in Information Society research, whether at European, national or regional level - or even entirely within the private sector. The general theme is 'Partnerships'. The aim is to help Europe's researchers and industrialists build networks for collaborative IST research, at a time when the IST priority within the EU's 6th Framework Programme for research and technological development is getting underway.
The 68th IFLA General Conference and Council [12]will be hold from August 18th to 24th 2002 in Glasgow. This year's focus will be on Libraries for Life: Democracy, Diversity, and Delivery.
DigiCULT will have its own stand on the IFLA 2002 exhibition and over 20 of our funded projects will participate and present their activities. Volume 3 Issue 3 of our eCulture newsletter will have a special supplement on our participation in this exhibition.
In this issue we would like to draw your attention to our "Heritage for All" Key action line, which is funding projects that aim to reinforce Community Memory.
"Heritage for All" was the theme of KA III.1 .2, one of the two cultural heritage action lines in the 6th call for proposals launched in January 2001 within the context of the Information Society Technologies programme, under the Fifth Framework Programme.
In line with the objectives of the eEurope initiative, to provide content for all and ensure digital inclusion, "Heritage for All" aimed to "foster sustainable online communities by creating and documenting the digital record of their societies, including safeguarding its accessibility for the future''; in other words, to provide a context for documenting, sharing, accessing and preserving community heritage and collective memory in digital form. Conceived to encourage participation by smaller scale cultural and memory institutions, as well as to initiate citizen-, rather than technology-driven projects, this action line focused on the enhancement of local and regional cultural resources by developing digital archives to document past and present social history and cultural expression for the use of the widest possible range of individuals and groups of citizens. In this context, projects were selected which encouraged, to a greater or lesser extent, active participation of diverse on-line citizen communities in producing an evolving digital record of their culture.
CHIMER, CIPHER , COINE and MEMORIAL, the four projects that make up the "Heritage for All" cluster, are each of 30 months' duration. In some cases, preliminary results will start to emerge towards the end of this year. The first three of these projects all seek to address the personal views and interests of ordinary people in order to build a living image of regional heritage across Europe. MEMORIAL focuses on developing a methodology for digitising content of a very specific nature and making it available to the general public.
MEMORIAL [13] deals with a dark side of our recent history, the Holocaust, and focuses on data documenting former Nazi concentration camp prisoners in order to create a digital personal records archive on the Web. The project aims to increase awareness of, and facilitate access to relevant historical information for the general public, while simultaneously providing an invaluable and dedicated data resource for the use of special-interest groups, for example relatives of victims researching their family history.
Research work in support of the virtual MEMORIAL archive will provide a new technical approach, based on OCR (Optical Character Reading) techniques, which will be more generally applicable to a wide variety of paper documents in libraries, archives, museums or public record offices.
The MEMORIAL partnership brings together OCR and digital archiving experts from Germany, Israel, Poland and the UK. They combine to develop an innovative methodology and achieve optimum digitisation results, most notably, higher resolutions based on new imaging technologies. These technologies will tackle traditional problems, such as the poor quality of faint carbon copies, which are the main source of prisoner records, the inclusion of hand-written comments and rubber stamps and the presentation of data in columns of various types depending on the source. In addition, MEMORIAL makes use of technology methods capable of addressing problems of another nature, such as content-resolution problems, which are, for instance, due to variations in family and place names (e.g. in Polish, Russian, Italian).
The strong technical component of the project is crucial in terms of the application and development of technologies within the MEMORIAL context could be widely applied in digitising other kinds of paper-based documents, thus making use of new types of content.
CHIMER [14] sets out to capitalise on the natural enthusiasm and interests of children in developing new approaches to the use of evolving technologies for documenting items of cultural interest in their local communities. To achieve that, CHIMER will establish an international network of educational and cultural institutions, which, supported by technical partners, will work towards enhancing children's interaction with technology, so as to enable them to create on-line cultural content.
More specifically, twelve-year-old children in different parts of Europe will follow the guidance of museologists and teachers in building digital maps combining geographical coordinates detected using GPS devices with the creative use of mobile technologies and digital cameras. In this way, children from Bohemia to La Coruña and from the Netherlands to Lithuania will combine drawings and photographic images with their own comments on items of interest. Little by little they will participate in creating a digital archive of their own towns, villages and surrounding communities, which should enhance interest in the region, not only for children but also for other age groups.
CHIMER hopes to offer a model which can later be replicated on other networks, not only in the area of culture but also, for example, for public sector information, health and tourism, based on the use of digital cartography linked to multimedia databases.
The creation of a user-friendly web based environment which will enable ordinary citizens to record, present and share their personal and local cultural heritage, lies at the heart of the COINE project [15]. Partners work together to develop a toolkit of software tools and techniques for digitising, creating and maintaining multimedia resources which are brought together to build up a coherent cultural domain exploitable by individuals and small groups.
The overall aim of the project is to provide ordinary citizens or groups of citizens with software, which can support them in documenting and sharing their cultural interests, as well as exploring their local heritage. People of varying IT competence, age, social and educational background will be engaged in creating, managing and making available cultural content of the utmost importance to them personally. Practical examples of the usability of the COINE system by local communities in Greece, Spain, Poland and Ireland are:
Aiming to promote and preserve a living view of regional heritage across Europe, CIPHER [16] is committed to providing methods and tools that enable individuals and groups of people to document their reactions and experiences from interacting with their local heritage. Research work will focus on the construction and maintenance of four Cultural Heritage Forums, four on-line thematic collections of various heritage items, (archaeological material, historical documents, monuments, music, oral history, etc.), intended to trigger visitor participation and encourage active interpretation of heritage. Provided by a network of cultural institutions, the content of each forum highlights the distinct cultural identity of a European region that may transcend country borders. Forum themes include "Irish Cultural and Natural Heritage", "Nordic Heritage through Storytelling and Historical Artefacts", the "Shared Heritage of Central Europe" and the "Tradition of Technology Innovation in South Central England". Members of local communities are encouraged to explore, research and, more importantly, contribute creatively to content building for these cultural domains. Innovative tools for story construction supported by visualisation and virtual world technologies allow users to weave their own narratives and forge new associations across digital artefacts.
By developing dynamic, user-centred applications that serve as focal points for regional communities to interact with their local heritage, the CIPHER project seeks to support ordinary people in creating personalised content in order to share their group experiences and history.
And here is some news on internal issues: Behind us lies quite a long period of global restructuring of the IST Web pages. During this time, not being able to implement any changes or updates on our pages, we did our best to keep you informed via our newsletter eCulture. But since 24th May, the new system is online and we are busy updating our pages. If you should still happen to find - for a hopefully very short period - incomplete or outdated information while searching on DigiCULT, please feel free to contact us [17].
Finally, we would like to add that the work in the Information and Communication field in our Unit is now done by Christine Michaut who has succeeded to the post formerly held by Concha Fernandez de la Puente.

By Rosalind Johnson - July 2002
Rosalind Johnson reports on the DLM-Forum 2002 conference, Barcelona, 6-8 May 2002.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
In unseasonably wet and windy weather, records managers, archivists and information professionals gathered in Barcelona to attend the third DLM Forum on access and preservation of electronic records [1]. DLM is an acronym for the French Données lisibles par machine, or in English translation, 'machine readable data', although at the conference the acronym DLM was given an English meaning: Document Lifecycle Management.
The DLM-Forum is based on the conclusions of the Council of the European Union of 17 June 1994 concerning greater co-operation in the management of electronic records. It was created as a platform for collaboration between technology providers and public institutions and administrations to address the issues involved in electronic records management, including technical solutions and the creation of guidelines and model requirements. DLM has published and sponsored a number of reports. Two previous European-level conferences have been held in 1996 and 1999.
The wealth of parallel sessions meant that I was unable to sit in on every presentation; and choices had to be made [2]. I chose to attend those sessions featuring 'best practice', especially those covering European Commission (EC) funded projects. Those which seemed to include the most relevant examples for my work included the sessions on the memory of the information age (preservation, migration and longer-term availability), the use of public information, and improving access to knowledge (training and education for information experts and users). This involved some swapping between parallel sessions, and, being unable to bi-locate, I was regrettably unable to attend other conference tracks and workshops which formed a significant part of the programme. These included parallel sessions on content management and delivery, organising records and archives, and capturing and transforming information with automatic indexing technologies and retrieval solutions. I was also obliged to miss the workshops on metadata, digital signatures and the legal admissibility of digital storage. However, that should give an insight into the overall content of the DLM-Forum, and the amount of information being presented. At the conclusion of the conference, it was recommended that the conference papers be made available on the DLM-Forum Web site. At the time of writing, this has not yet happened, but if it does, it should produce some interesting material.
Among the EC projects presented, the Open Archives Forum is a new project set up to support European and national initiatives that adopt, or are willing to adopt, an open-archives based approach [3]. Special attention will be dedicated to those initiatives implementing or using the Open Archives Initiative Metadata Harvesting Protocol [4].
Another European project, e-TERM sought to develop and test a multidisciplinary and adaptable course for teaching electronic records management to archivists, records managers, IT personnel and administrators [5]. The course modules were designed to be delivered in a wholly electronic environment. With partners across Europe, this made administrative sense, and reduced the need for face-to-face meetings. Yet the need for human contact remained; for social contact when it did occur was found to contribute to a better mutual understanding and commitment. Although the project has formally ended, the partners hope to work together to develop a European centre for higher archival education and training.
Several examples of national projects and best practice were presented. Naestved Kommune in Denmark claims to be the first local government in the country to employ a complete digital signature system to enable total electronic administration for local citizens [6]. Already, 80 per cent of households have access to a broadband connection. The aim is to focus on the different needs of citizens at different stages of their lives to provide a fully comprehensive service. This will be facilitated by the use of digital signatures, although there are legal issues to consider regarding the need for hard copy documents to be produced.
Frank Brady of the European Commission gave an interesting presentation on the EC's efforts to set up a single document management system. Investigating claims that 600 separate document management systems existed within the various EC departments led to the discovery that some 2,000 different systems could be identified. Developing a single new system was a considerable challenge, not only technically, but also with reference to convincing, and indeed coercing, EC staff into accepting the new system. The new electronic document management system will not only have to deal with internal administration, but also with the 8,000 external requests the EC receives every year for documents. Additionally, the query system must take into account different languages - for example, the many variants of the phrase 'mad cow disease'.
Despite the challenges faced by Frank Brady and his team, the new system should improve access to documents for EC staff and ultimately for Europe's citizens. A standardised procedure across the EC will demonstrate its transparency to the public. The EC has a reputation for secrecy and bureaucracy among the public which it has been working to correct; this is part of that overall work. The improved procedures will also benefit staff, by facilitating mobility and communication across different departments.
Emphasis was given at the conference to announcing and promoting: MoReq, the
model specification for the management of electronic records [7]. This has
been developed under the EC's IDA (Interchange of Data between Administrations)
programme [8]. MoReq is a high level specification, but also fairly comprehensive in
its approach. MoReq is largely intended for the archives community and is mainly
applicable to records which are originated and managed in the public sector. This
reflects its origins in archival standards, and their application to public
procurement of electronic records management systems. However, the impact of
MoReq could be felt elsewhere. One conference delegate felt this might be the
case if the EC's dreams of greater commercial exploitation of public sector
information comes to pass.
There were a few technical hitches during the conference. At least two speakers found their slides were unavailable, and one speaker chose not to speak at all, rather than present without them. This apparent reliance on technology has, of course, parallels with generations of lecturers reduced to canceling seminars on discovering that they have left their notes at home.
But new technology brings its own problems. Speaker Piero Corsini from IBM commented that people now demand information in 'two to three clicks', an impatience particularly noted in young people. He believes that many user interfaces in the public sector are in need of improvement. Other speakers also focused on the issues of the user interface and the need to involve users in the solutions to the problems of electronic records management; not only public servants who use such systems at work, but the citizen trying to access information and services.
Ulrich Kampfmeyer of AIIM International spoke of his belief that we stand at the beginning of new developments. The traditional problems of records management involved paper - its bulk, its relative fragility, its indexing. More recently, the migration to electronic management of records involved considerations of whether or not to preserve the original hard copies, and the durability of digital systems, but paper was still the core of the business, especially as multiple photocopies and print-outs found their way into filing systems across the world.
But with digital information, we face a new set of challenges unique to that environment. Ulrich Kampfmeyer quoted a statistic that the amount of information available world-wide now grows in one year more than in the previous 2,000 years. Much of it has no physical representation, and is therefore totally reliant on electronic systems for its survival and its use. Unlike the single physical format of paper, electronic data may be available in several formats - digital video, digital voice, different software packages. Standards, such as MoReq, are therefore of crucial importance to ensure preservation of the data, and to enable its fast and effective retrieval and use. The effectiveness of this use includes the training and education of users, and the design of efficient front ends and help systems.
Finally, a well-publicised feature of the conference were the six industry- sponsored White Papers on key issues facing electronic records in the public sector [9]. Summaries of these papers, and note of the conference conclusions, are available on the DLM-Forum Web site [10].

By Sanita Berzina - July 2002
Sanita Berzina reports on the conference "Co-operation of Museums, Archives and Libraries in the Electronic Era - Experience, Reality, Strategies for the Future", held in Riga, 25 - 26 April, 2002.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
This conference was held in Riga, the capital of Latvia. It ran for 2 days, both of which were well attended and which saw a high degree of activity. The conference was notable not least for the fact that this was the first time that archive, library, museum and IT specialists from Estonia, Latvia and Lithuania had met in such numbers.
 |
| Figure 1: Opening Session of the 1st. e-MAL Conference of the Baltic States |
The importance of the conference can be estimated when one considers these two points. Firstly, it united specialists from museums, libraries, archives and IT in the Baltic States and from other countries. Secondly, the conference was devoted to what some might consider three quite different cultural areas - archives, libraries and museums. As such it helped to raise awareness of the current state of these branches in the context of digitisation. In addition, it ensured the sharing of experience across the national, local and international levels.
The main objectives of the conference were:
The process of digitization of archives, libraries and museums has just begun in the Baltic States. With but a few exceptions there is no access to digitised collections on the Internet and practically no capacity to use metadata for searching for digital objects.
In order to coordinate the digitisation of information resources, it will be essential to foster co-operation between archives, libraries and museums in Latvia and the other Baltic States. One of the main things to be done is to achieve agreement on common digitisation standards, both on the national and international level, but, first of all on the institutional level. Another major goal will be to promote the development of unified programs and strategy for digitising.
The majority of conference participants were the specialists from archives, museums, libraries, IT and other fields, not only from the Baltic States, but also from Canada, the Czech Republic, Germany, Russia, Scandinavia, and the United Kingdom. All in all, there were more than 25 presentations given over the two days of the conference.
On the first day of the conference, held at the Riga Latvian Society, 14 speakers participated: M.Andress, E.Becker (Germany), S.Bang (Norway), N.Brakker (Russia), K.Cerans, A.Vilks (Latvia), L.Johansson (Sweden), A.Knoll (Czech Republic), A.Lepik, M.Siiner (Estonia), A.Plioplys (Lithuania), B.Royan (United Kingdom), J.Saarinen (Finland) and T.Wanning (Denmark). They gave a deep insight into various national and regional projects providing a clear picture of what been done in the other countries in the context of digitisation, a run-down of the main issues to be confronted and a view of the most successful solutions.
On the first day there were 212 participants, including 61 library specialists, 48 museum specialists, 39 archive specialists, 44 specialists in other fields and 20 guests.
The second day of the conference was organised into three sections:
Given the close proximity of the substance of sections A and B, it would have possible to have considered them jointly.
In section A, held in the Institute of Mathematics and Computer Sciences (University of Latvia), the presenters, K.Alev, H.Helves (Estonia), S.Berzina, A.Spektors (Latvia), N.Caidi (Canada), and I.Kondratieva, D.Roubashkin (Russia), covered a wide range of themes: issues of national information policy and the role of archives, museums and libraries therein, library standards in Latvia and the importance of national and international projects within cultural heritage institutions in the age of technology were examined.
Section B was held in the Latvian Academic Library and there were 4 speakers participating: A.Aboltina, A.Glosiene (Lithuania), R. Kalnina (Latvia ), and K.Saarevet (Estonia). The speakers gave a presentation on the current situation in the sphere of digitisation in the Baltic States, looking for the best solutions and likely directions activity would take towards the successful development of digitisation.
Section C was concerned with questions of restoration. It was held at the Riga Latvian Society. Three speakers from Latvia, M.Dzenis, I.Limane and I.Rudzite gave presentations on the current situation, the problems and solutions regarding restoration in Latvia together with comparisons with the experience of other countries.
On this second day highest activity was observed in section A "Metadata, Standards & IT" : 49 people took part. 38 participants were attended section B and 32 section C.
 |
| Figure 2: Section Reports Session |
In conclusion, overall, attendance at the conference may be regarded as very satisfactory , taking into account the small number of working specialists in these spheres in the Baltic States. Participants' interest was clearly discernible from the lively debate that ensued following each session's formal agenda.

By Richard Wright - July 2002
Richard Wright reports on the Multimedia Archive Preservation Workshop held in London this May.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
During the period 22-24 May 2002, about 130 people directly involved in multimedia preservation gathered in London to review the problems and learn about new solutions. The workshop had an international audience, from Africa, the Caribbean and North America as well as from Europe. About 1/3 of delegates were from outside broadcasting, representing audio, film and video collections in a range of cultural and academic institutions, from the Edison National Historic Site to the National Archive of Malawi.
The workshop was sponsored by four organisations working together:
PRESTO and the BBC took the opportunity to host the 5th IASA/FIAT seminar on digitisation, and extend it to cover PRESTO results, and present them to an audience that extended outside FIAT/IASA membership.
In order for people to get maximum benefit, people new to audiovisual archiving also attended a training day on 21 May, where the BBC archive operations and policies were presented. Also, half of the final day was devoted to tours of actual preservation work by the UK National Sound Archive, British Film Institute, and the BBC.
In a very packed three-day programme, there were 27 formal presentations, covering the following areas:
Presentation of all 14 PRESTO 'new technology' key links, and an equipment demonstration of the actual devices up and running. There were also presentations covering restoration work: EC projects BRAVA and DIAMANT. The afternoon focussed on non-broadcast archives, to keep the balance from the morning's concentration on PRESTO technology for broadcast archives. Two presentations from Vienna showed both the range and depth of the problems (Dietrich Schüller, Phonogrammarchiv - Austrian Academy of Sciences), and a very inspiring solutions: an audio collection could be fully digitised with datatape robotics and interned access (Rainer Hubert, Austrian Mediathek).
The day concluded with seven informal presentations from a range of cultural archives, from Malawi to the US Library of Congress. A very informative discussion took place on what preservation really meant, what planning, technology and funding it required, and the role of PRESTO technology in small and diverse collections.
The third day began with tours to the actual preservation work at BBC, BFI and NSA, followed by informal presentation from six broadcast archives. In was notable that although the size and history of the six archives varied greatly, from the BBC to new archives in Albania and South Africa, the broadcast archivist had very close agreement on both what they meant by preservation, and the approach they would use (the high throughput 'preservation factory'). The problem for small broadcast archives is that they cannot invest in setting up such a factory themselves, so there was a clearly-expressed demand for central facilities - preservation factories - to provide cost-effective preservation services. The other clear need was for better information on preservation: what equipment and what media is good - and bad, where to get it, how to use it - and the problems people have had with media and equipment.
For me, it was a pleasure from beginning to end to bring together this wealth of experience and interest, and PRESTO will live on after the EC funding ends, to work with IASA, FIAT and other organisations to continue this essential educational work.

By Pete Cliff - July 2002
Pete Cliff fills us in on a useful tool for Web site owners that brings them distinct benefits with relatively little maintenance effort and enhances what the site can offer to its users. This is an enthusiast who can provide different approaches to implementing RSS.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Imagine you could create a Web site that keeps your users informed of the latest news, jobs and resources available in a given subject area in addition to any content you wish to provide. A site that is updated automatically so that once you have set it up, it looks after itself, with minimal maintenance from you. Sounds like so much fiction? A little idealistic perhaps, but it is this sort of thing that a technology like RSS aims to provide.
This article explores what RSS is, how it may be used, and finally summarises some of the tools you may use to make the job easier. We begin with the obvious question:
Depending on whom you ask, RSS stands for either "Rich Site Summary" or "RDF Site Summary". The debate is old [1], and this article will not concern itself with that discussion. Suffice it to say the ideas and the motivation behind the creation of an RSS channel remain the same, regardless of the "flavour".
XML Deviant Leigh Dodds defines RSS as:
... an XML format for syndicating metadata about online content [2].
RSS is an XML format designed to enable the sharing of online content metadata. It can be used to describe the content of a Web site in a way that can be re-used by others. Because it is XML, it facilitates the full automation of the sharing and display of this metadata.
The use of RSS benefits everyone involved. As a Web site provider you get free content; as a content provider you make your content visible to a broader audience through a larger number of sites; and as an end user you get the benefit of a broad range of content available at a single site.
RSS is an incredibly flexible format. It can be used to describe just about any sort of online content. The latest news, the new books in the library, job advertisments and similar content can be pointed to via an RSS channel. That RSS channel can then be used by other institutions or local departments.
Imagine that a university carries around twenty links to campus (and other) news stories on its internal homepage. Each of the departments within the same university has similar news "channels" on its homepage in addition to departmental news. Imagine users are interested in finding out about new research grants awarded in each department. Unless the homepage was very comprehensive, they would have to visit every department, fairly regularly, just to keep up to date. If they have their own favourite external news feeds, the problem gets bigger.
If each of the departments chose to export its news as RSS channels, it would be a simple matter for the institution to create a single "information point" that syndicated all of the news across campus onto a single page.
| Figure 1. uPortal[3] supports the use of RSS to create institutional portals, like this demonstrator at the University of Nottingham[4] |
This idea could be extended further to provide the end user with the option to search the channels, or personalise which channels are displayed. This is, in effect, the beginnings of an institutional portal. A portal where the content creation is distributed, but access is at one point for any end user.
A very similar scenario could be imagined for users of a public library, where local news, jobs, new books, etc. may be syndicated onto a single library homepage, but the news is collected from other sources, including local goverment pages.
The key advantage is the devolution of Web site maintainence, (devolution that may well exist if departments all have their own pages), to those who know best, but which provides a mechanism to provide a central, one stop access point to all of this information.
Many Web homepages are lists of news items that highlight events, publications, and so on. If not the homepage, then a great many sites have news sections or pages that are lists in this way. It makes sense to provide RSS views of these listings, but this creates a problem. If you have an HTML view of a page, and an RSS view, you will have to update them both. This creates a problem of synchronicity.
There are many ways around this problem. Perhaps the most elegant is to put all of the news stories in a database and generate both RSS and HTML views from this data. However, if there is a single database this can remove the benefits of devolved maintainence of RSS channels. A database is also a fairly development heavy solution. If, however, you were looking to move your entire site into a content management system you may want to check if content can be exported as RSS as well as HTML.
There is a compromise: generate the HTML for the site from the RSS, or vice versa.
This approach has been explored by the World Wide Web Consortium [5] and has been implemented by a few sites[6]. The idea is to include a set of fixed "classes" into your page (which must be well formed XHTML), and, provided the HTML can be parsed correctly, a script is able to convert the content of these classes into well formed RSS.
For example, look at the following HTML fragment:
<p><span class="rss:item"><a name="26-06-02"><strong>26 June 2002</strong></a><br />
<small class="rss-anchor"><a href="http://www.ukoln.ac.uk/web-focus/events/workshops/webmaster-2002/news.html#26-06-02">Workshop Conclusions</a></small><br />
The <a href="talks/conclusions/">workshop conclusions</a>, given by Brian Kelly,
are now available online. </span></p>[7]
Here we see that an item is enclosed in a single span and the link for that item is given the class
rss-anchor. This enables an XHTML to RSS converter to create an RSS channel from this
Web page.
| Figure 2. HTML to RSS. A script is used to parse the HTML page and extract the relevant sections. This information is then used to create an RSS XML file. |
This approach has been adopted by a number of sites. Webreference[8] for example, or closer to home, the RDN[9]. The two "channels" on the RDN homepage (see figure 3) - Behind the Headlines and the RDN News - are automatically generated from two RSS channels [10]. We use the same two channels to create the News[11] and Behind the Headlines pages[12]. This means RDN staff need only maintain a single copy of the metadata, but it can be resurfaced in a number of ways.
| Figure 3. The highlighted area is created from two RSS channels. |
UKOLN's home page[13] is essentially a list of news items that highlight events, publications, announcements, etc.; in effect what has been happening at UKOLN. This list of news items is maintained as an RSS channel. It works like this, (numbers in brackets relate to diagram in Figure 4):
| Figure 4. RSS to HTML (see list above) |
UKOLN derives a number of benefits from this approach:
The approach adopted by UKOLN was, in fact, very easy to implement. However, it will
not suit all Web sites, nor will everyone have the time, effort or access to the server
to add SSIs, or write scripts. There has been some effort towards overcoming this problem
by making adding an RSS news feed to your page as simple as adding a <script>
tag.
For example, by pasting the following HTML into one of your Web pages will automatically include the RDN's "Behind the Headlines" RSS channel into that page:
<script src="http://www.rdn.ac.uk/rss/viewer/?rss=http://www.rdn.ac.uk/rss/channels/behind-the-headlines.xml" ></script>
The "source" of the script tag is the URL of the RSS parser script, in this case the one
used by the RDN (1). Part of that URL includes the location of the RSS to parse and return to the browser.
The RSS parsing script then retrieves the RSS channel (2), the RSS is then parsed and some HTML is created.
Because the browser is expecting to get JavaScript back, this HTML is then wrapped in document.write()
statements and passed back to the Web browser (4). At this point the Web browser has some standard JavaScript
and deals with it in the usual way. (Numbers in brackets refer to diagram in Figure 5).
| Figure 5. RSSxpressLite |
Examples of this approach can be seen at:
Because this way of including a channel means the channel is only included by a Web browser on processing the JavaScript, channel content does not get indexed by some robots. Because of this, it is not recommended to use this approach where indexing is important, for example, the UKOLN homepage.
RSS can provide you with ways of adding external content to your site, but what content is available? Because RSS has been around from a while and has been something of a success, there are many channels you can use. Public content can usually be found in registries of channels:
So you like the idea of RSS? You want to get out there and start using RSS. But I guess you want to know how to create it, what does it look like? You may, if you are thinking "RDF Site Summary", be getting nervous about the syntax and the complexities of RDF? If that is case you needn't worry. You can get by with RSS 1.0 with a minimal knowledge of RDF (though you may wonder about some of the syntax), and if you are not interested in RSS 1.0 then the 0.9x versions appear far simpler and are still supported.
When it comes to creating RSS there are many ways you can go, and many tools you can use:
If you are lucky enough to have a content management system, or you simply serve your Web content from a database, then you will find creation of RSS very easy. Many CMS's will export RSS for you and if they don't you (or your friendly programmer) can easily add RSS export support using one of the many tools available[21]. Otherwise an editor will quickly get you started with RSS creation.

However, you don't need to get caught up with worries about using RSS. Tools are available, such as the JavaScript options, that make using RSS very easy. There is no requirement for you to create RSS (though you may want to) before you can benefit from the myriad of content available.
Hopefully by now you will be starting to see the benefits of a technology like RSS. It provides a simple way to syndicate online content. Implementation may be as simple as including some JavaScript in a single Web page to using a content management system to syndicate external content and export your content for others to use.
Either way, the benefits of this easy, open XML success story, are clear.

By Kim Veltman - July 2002
Kim Veltman believes the semantic web should be about the meaning of humanity with all the richness of its cultural and historical dimensions. Here he reviews three approaches to the semantic web, namely of the World Wide Web, Dublin Core and a small group within the AI community. He then suggests that a new kind of cultural semantics is needed in order to reflect the richness of human experience.

The semantic web [1] is analogous to motherhood and apple pie. Everyone agrees that it is a good idea. 'Semantic', as the Oxford English Dictionary tells us, has to do with meaning and everyone wants meaning [2]. As is so often the case when everyone thinks that they agree, it may be that the meaning of meaning is not as clear as it seems; that persons are actually speaking about different things, and that there is a danger that they are speaking past each other. This paper suggests that there are at least four approaches to the semantic web, namely that of:
A brief survey of the four approaches is given. It is claimed that the first two approaches are correct but too narrow; that the third is misleading, while the fourth represents a direction full of challenges to which we should aspire.
At WWW7 (Brisbane, 1997), Tim Berners-Lee outlined his vision of a global reasoning web. At WWW8 (Toronto, 1998), he articulated the vision of a semantic web, whereby one can separate rhyme from reason: i.e. the subjective dimensions of art and poetry from the objective dimensions of logic, which is one definition of science. At one level, this is a direct continuation of the vision, which inspired Shannon, which itself grew out of the subject-object distinction that Cassirer [3] traced back to the Renaissance. In some senses it also goes back to the Greek debates about universals and particulars. In terms of the classical trivium of grammar (the structure of language), dialectic (the logic of language) and rhetoric (the effects of language), the emphasis of Tim Berners-Lee on the logic of language reflects the concerns of the dialectic in Antiquity.
In the vision of Tim Berners-Lee [4], there is a great emphasis also on distinguishing the basic structure of content from the various forms in which it is expressed. In the trivium, this is the distinction between grammar (the structure of language) and rhetoric (the effects of language). There is corresponding attention to the quadrivium. Optimists will note that the makers of the World Wide Web (W3) Consortium are addressing all the questions of the ancient trivium and quadrivium such that all the potentials of the traditional seven liberal arts will soon be available in electronic form (Figure 1). At the same time there is a danger in being over-optimistic and in being too easily satisfied. Separating rhyme from reason is useful. Creating a web which focusses only on reason at the expense of poetry may not be sufficient.
Logic is, of course, an excellent starting point. Tim Berners-Lee has a conviction, which can be traced back to the early history of Oxford from whence he comes, that logic is a way to separating the wheat of truth from the chaff of idle claims. Logic is universally applicable: it reflects the scientific spirit. It represents the dimension concerning which there ought, in theory, to be no debate. Logic has the added value that it can be very useful in the realm of transactions. If we can sort out which accounts are true and which false, this can greatly help the rise of e-commerce.
| Grammar | Structure, Syntax [5] | Extensible Markup Language [6] | XML |
| Dialectic | Logic,Semantics | Resource Description Framework | RDF |
| Rhetoric | Effects, Style,Pragmatics [7] | Extensible Style Language | XSL |
| Geometry | Continuous Quantity | Mathematical Markup Language | MML |
| Arithmetic | Discrete Quantity | Mathematical Markup Language | MML |
| Astronomy | Applied Continuous Quantity | Astronomical Markup Language | AML |
| Music | Applied Discrete Quantity | Standardized Music Description Language | SDML |
All this is excellent. Meaning, however, is about much more than transactions. Whereas the meaning in logic and science focusses on the universally true, meaning in the realms of culture typically focusses on what is nationally, regionally or locally unique. Science is in large part uni-lingual and uni-cultural. Culture is multi-lingual and multi-cultural. The solutions of science have become the models for our treatment of all domains of existence. Today when we search for a word on the Internet there is an implicit assumption that we are searching for a single meaning. For the realms of culture we need a semantic web, which allows us to discover differences in meaning in different places and at different times. We shall return to this in the section on Cultural Semantics.
The W3 Consortium works closely with the Dublin Core (Metadata Initiative), which was inspired in part by the vision of Yuri Rubinsky (1994) for a metadata semantics [8]. This set out to identify a minimal set of universally applicable fields on which one could hope to gain international acceptance. These fifteen fields, known as the Dublin Core, were initially intended to describe web sites developed by persons without formal training in the principles of library cataloguing (e.g. MARC). In the eyes of some the Dublin Core has much grander applications in memory institutions. In any case it can serve as a very useful bridging device to connect otherwise heterogeneous resources. The Dublin Core initiative helps to reach agreement on matching effectively equivalent fields in different systems: a process which is alternatively called mapping, bridging, linking, creating crosswalks, walkthroughs or more generally interoperability. Interoperability of content is at least a twofold problem. There is interoperability of:
The initiators of the Dublin Core use semantics to refer to the definition or meaning of the fields (or elements). They deal with part one of the problem and this is very important. Without basic agreement concerning the fields there can be no sharing of information and knowledge. In other words, in respect of fields/elements/containers we must first decide that Subject and Topic are equivalent. But interoperability of content entails a second part: in respect of the meaning of terms in the fields we then need to agree that the subject/topic of car and the subject/topic automobile are equivalent.
In the case of car and automobile almost everyone will agree that the terms are equivalent. In the case of a word such as pasta, in Italy alone there are well over 60 definitions. In science, one internationally accepted definition of a term or word is all that is needed. By contrast in the realm of culture there is typically a definition at the international level and variants at the national, regional and local levels. Both the W3 and Dublin Core use science as a model. This approach based on logic and universals is excellent in the case of scientific knowledge, but is too narrow to deal with the particulars of multi-lingual, multi-cultural and historical cultural knowledge. For this we need a cultural semantics.
The authors of the Dublin Core and the W3 may rightly protest that this is a level of semantics, of meaning, which they never intended to solve and this is a reasonable position. Nonetheless, the problem remains. Without a means of separating these different kinds of meanings, we shall not have a semantic web which can address the complexities of culture. Indeed, we need more, because these meanings also change historically, such that a term, which meant one thing in the 17th Century may mean something very different today. Hence the word 'nice', which in the 17th Century frequently meant lazy, lewd, or lascivicious, now means something quite different when persons speak of "a nice day". We need new kinds of search engines which do not simply search for a "natural language" term, but allow us to distinguish between local, regional, national, and international levels, multi-lingually, multi-culturally and historically (i.e. including etymologies).
Within the field of Computer Science and particularly among a small group of individuals in Artificial Intelligence (AI), semantics has a much narrower meaning. Here the quest is to arrive at a supposedly objective machine-readable code whereby machines can make decisions without human intervention. In this context, meaning is reduced to efficient commands and decision trees. There is an assumption that if the code were perfected then humans would no longer be necessary. For instance, computer scientists such as Carl Hewitt have claimed that one needs to replace humans with robots in the case of decision systems. The quest is to create machines:
"that could take care of us, that could be our guardians and that would also be our rulers and policemen to program computers and robots that could garner all the weapons of mass destruction into a machine-controlled system, in the same way that you have to take matches away from children [9]."
According to the supporters of this school, all decision-making concerning military actions, when to send planes, drop bombs, etc. needs to be removed from the human sphere and the goal is to turn the keys [10] for all such actions over to robots. To this end, the army, navy and the air force are all working on autonomous decision robots [11]:
"The necessary turnover in personnel you get in human-based systems, because of their very short lifetimes, seems to throw instability into the system. And the general diversity of human stock we have, in terms of different languages, cultures and interest is not something that can be smoothed out very quickly [12]."
In this approach the subjective meanings of humans with their many languages, cultures and attendant ambiguities are merely a nuisance and ultimately meaningless. The profound dangers of such a quest were pointed out nearly three decades ago by the Nobel physicist, Joseph Weizenbaum (1976):
"The computer has thus begun to be an instrument for the destruction of history. For when society legitimates only those 'data' that are "in one format" and that "can easily be told to the machine" then history, memory itself, is annihilated. And the curious paradox is that the immortality of knowledge means the death of culture [13]."
These dangers were restated a decade later in Grant Fjermedal's "The Tomorrow Makers", (1986), a fascinating book on the development of living brain machines [14]. Fjermedal noted that this vision of autonomous decision robots was a quest for a non-biological intelligence which, according to Richard Jarrow, founder of NASA's Goddard Institute, was destined to replace humans altogether [15].
This goal of creating autonomous decision robots helps to explain a growing fascination with and commitment to natural language and so-called common sense worlds, which were described by Jerry Hobbs and Robert Moore (1986) [16]. It helps explain also the rise of artificial intelligence projects such as Doug Lenat's CYC, Generic Artificial Consciousness (GAC) and Common Sense [17]. It suggests a deeper reason for the Defense Advanced Research Projects Agency's (DARPA) very active participation in Knowledge Query Markup Language (KQML), Knowledge Interchange Format (KIF), DARPA Agent Modeling Language (DAML) and, possibly, their increasing role in W3's quest for a semantic web.
One is tempted to dismiss such a quest to replace human intelligence by machines as efforts of a marginal minority in the military. However, analogous ideas are being developed in the realm of American industry. For instance the authors of "Visionary Manufacturing Challenges for 2020" foresee new techniques evolving independently of language and culture, which is the opposite of the European approach:
"A major task will be to create tools independent of language and culture that can be instantly used by anyone, regardless of location or national origin. Tools will have to be developed that allow for effective remote interaction. Collaboration technologies will require models of the dynamics of human interactions that can simulate behaviors, characteristics, and appearances to simulate physical presence [18]."
By implication there are two fundamentally different visions of a semantic web. One aims at understanding human meanings, which vary from place to place and vary historically. A second aims to use natural language and common sense to offer a single language for robots acting independently of humans with no reference to cultural diversity and the complexities of history. In our view, the first vision needs to be developed. The second is misleading and dangerous. It implicitly undermines the larger vision of the W3 Consortium as a world wide web for humans. Ultimately the second vision is a threat to the human race.
Historically, there have been other, more subtle, trends working against multilingualism. Ever since the scientific revolution in the Renaissance there has been a gradual tendency towards international standards which gained enormous ground in the Nineteenth and Twentieth Centuries with the rise of many international organisations such as the International Standards Organization (ISO), International Telecommunications Union (ITU), and the United Nations Educational Scientific and Cultural Organization (UNESCO). Underlying these bodies was a vision that one needed to reach agreement on terms in order to make progress. Local and regional agreement were first steps, national agreement was one step further and international agreement on a term or concept was ultimately the goal.
In the realms of science and technology this is essential. Science is concerned with universally valid laws and rules. Hence we need globally accepted definitions of zinc, chemical formulae and the like if we are to have an international scientific community. This is also the case in medicine. Our definition of a heart needs to be the same if surgeons are to operate successfully around the world. This quest also relates to Tim Berners-Lee's assumption that meaning is closely linked to logic and thus with things which can be proven. Hence his notion of a semantic web strives for information or knowledge that is universally true.
In the realms of the arts and culture, however, the situation is different for three fundamental reasons. First, the cultural sector has a historical dimension, which is central to its existence. In the case of science, the focus is on the laws and rules which apply now [19]. In culture, the arts and the humanities, the historical commentaries on great authors such as Homer and Shakespeare or on great artists such as Leonardo da Vinci and Rembrandt are not just of passing interest. They are central to the field, for the depth of culture lies precisely in the cumulative effect of these historical commentaries over the ages. Indeed these commentaries over time give cultural objects such as the text of Shakespeare's "Hamlet" their full importance. Hence, whereas science deals with laws, rules and formulae, which function as if they were a-temporal, cultural objects entail an essential temporal dimension. In science, a database of current formulae and definitions may be sufficient. In the realm of culture we need databases which include historical definitions, (etymologies) and make visible the cumulative dimension of cultural objects.
Related to this is a second difference. The goal of science is to arrive at truths or at least working hypotheses concerning which there is global acceptance. The greater the acceptance the more scientific a claim becomes. In the cultural sector, global agreement is extremely rare. Even in the case of UNESCO World Heritage sites there is often disagreement about what should be included. Indeed the richness of the cultural sector lies precisely in the amount of disagreement; in the diversity of interpretations concerning the same object. Hence, whereas science needs databases to record those 'facts' on which there is global agreement, culture requires databases to record all the disagreements concerning a given cultural object.
Hence the semantic web as it is emerging admirably reflects the needs of modern science and technology. But it does not yet answer the more complex needs of the cultural sector. Some might argue that this is not essential and merely a luxury. In a world where narrow identities of fundamentalist sects are threatening the very fabric of society, the need for identities with dimensions of tolerance many become our only hope for long-term survival as a civilisation. Meanwhile, economists who concentrate exclusively upon financial considerations need reminding that culture is intimately connected with tourism, which is the most important source of income in all the G7 countries and many other countries of the world. In addition to being fundamental to our sense of identity, it is thus also one of our most important sources of economic gain.
There is a third reason why culture is different from science and technology. Science is concerned only with globally accepted laws and rules. Cultural objects or products have local, regional and national variants. To take a prosaic example: beer has certain international standards, which are necessary to ensure that the brew is safe and not poisonous. But ultimately what makes beer interesting is that German beer is different from Dutch or Danish beer. Within a region and even locally there are many variants.
To take a more exalted example: paintings of the Annunciation are culturally rich precisely because there are so many national, regional and local variants. Hence a semantic web which aims to create databases with only a single definition of beer or of only one Annunciation, is not useful. In the case of cultural products or objects we need databases to indicate information or knowledge at the global, international, national, regional and local levels. And in an increasingly networked world we need ever more links between these levels.
Given the global nature of science, ultimately it is sufficient that there is only a single term for a given law, principle, rule or concept in a single language. Nuclear physics or radio astronomy do not preclude multilingualism, but one could argue that multiple languages merely risk adding further confusion to an already complex subject. By contrast, in the cultural sector local, regional and national variants are essential to the richness of cultural expression, and depend fundamentally on different languages and dialects. Thus a semantic web, which includes cultural, spatial (local, regional, national, global), historical and interpretative dimensions is one of the essential challenges that face us in the future.
Since the rise of the nation state there has been a tendency to compartmentalise knowledge. Local knowledge was stored locally, regional knowledge at the provincial or state level, national knowledge in the capitals of countries and international knowledge was stored in a few global libraries such as the Vatican and more recently in national collections (e.g. Bibliothèque nationale de France, Library of Congress).
The advent of new technologies and the Internet led in the first instance to a networking of the great international libraries and research institutions such as the Research Libraries Information Network (RLIN) and through projects such as the Gateway to Europe's National Libraries (GABRIEL). Such networks provide access to tens of millions and potentially hundreds of millions of titles. Through projects such as Gallica (BNF, Paris) the full contents of such titles are also becoming available.
Meanwhile, our search engines often implicitly assume that everything on the web is equally valid. Alternatively they perpetuate nineteenth century, positivist assumptions about terms: i.e. that, implicitly, when we search for a word a single definition is entailed. The quest to achieve interoperability of content further strengthens this trend. There is an assumption that unless there is complete equivalence between the meanings of fields, there can be no interoperability. Paradoxically, however, if there is a complete equivalence in contents of fields there is nothing gained in bridging meanings at different levels. Complete interoperability in this narrow sense would lead to precisely the McWorld effect against which Barber warned [20].
What is needed therefore is a more subtle approach. We need more than just the internationally agreed usage of a term. We need access to national, regional and local versions, with an indication at each stage about the level of agreement that exists concerning a term in a given language or dialect. Hence, when we search for 'heart', the system needs to provide us with terminology and a definition which have been internationally agreed and at the same time indicate national, regional and local variants. If the local interests us there may be cases where a local term is a) defined in a local dictionary or dialect phrasebook; b) where it is available in a recorded corpus and not yet formally defined or c) where it is used locally and not yet even systematically recorded. Until we have a framework which allows such distinctions, we cannot achieve full syntactic and semantic interoperability. Hence a challenge lies in a new synthesis of knowledge at local, regional national and international levels complete with new methods for reflecting these levels within our search engines and devices for navigating through networked knowledge. This is the challenge of cultural semantics.
The first half of the twentieth century introduced new ideas for computers, which transformed earlier concepts of computational devices which have evolved since the times of Pascal and Leibniz. The last half of the Twentieth Century transformed the notion of individual computers to an inter-networked world, whereby supercomputers and personal computers can be linked through computational grids. The notion of computers as devices concerned only with computation, number crunching, evolved also to include text, images, sound, touch and more recently smell and taste.
The 21st Century marks a new epoch in these developments. In 1995 there were 30 million users. In 2000 there were 300 million users and in the past two years the Internet has grown to over 544 million users. This figure is predicted to double again within the next five years. Within a decade more persons will have access to the Internet than has ever been the case with any other technology.
Freud, McLuhan, Levy and others have argued that computers should be seen as extensions of humanity: not only in the physical sense of mechanical tools, but also in a conceptual sense. Kurzweil would go further to claim that computers are extensions of mankind in a spiritual sense. In this context, the vision of a semantic web is one of the keys to the future. We need to get beyond number crunching and word crunching in order to get at the meaning of texts, images, and other creations of the human spirit.
We have noted that there are at least four approaches to the semantic web:
We have suggested that the efforts of 1) the W3 Consortium thus far are important, very useful for transactions, but do not yet answer the needs of human meaning; that the efforts of 2) the Dublin Core mark another important step forward, but that this cannot be seen as a comprehensive solution. We suggested that the approach of 3) a small minority in the AI community potentially undermines the vision of the W3 and is ultimately a threat to the human condition. What we need is a semantic web, which embraces cultural dimensions, which provides new levels of access to knowledge at the local, regional, national as well as international levels. The essence of science may lie in the universality of its claims, in universals. The essence of culture lies in the unique, in particulars, in the exceptions to the rule. We have exceptional databases for the universal laws of science but we have very little by way of databases for the unique and exceptional expressions of culture. To achieve this is one of the great challenges for the semantic web of the future: not to replace humans, but rather to find new ways of making visible their abiding expressions.

Tomas Lidman, National Librarian
at the Royal Library of Sweden recently announced a government decree that
places the Web archiving activities of the Library within the law. Work done
by the Royal Library in acquiring, preserving and making accessible everything
found on the Swedish Internet has hitherto remained in a grey area legally,
the Library feeling obliged to adopt a wait-and-see policy until its legal
position was clarified. As a result it has rejected all inquiries requesting
access to the material that it has archived. But now, with effect from 1st.July,
decree 2002:287 authorises the Royal Library not only to collect Swedish Web
sites on the Internet but also to allow the public access to its material
within the Library premises. [I hope it does not stop there.]

The current Internet 2
Land Speed Record was set on 9 April 2002 by
a team from the University of Alaska at Fairbanks; the Faculty of
Science of the University of Amsterdam and SURFnet, the national
computer network for higher education and research in the Netherlands.
The team transferred 625 megabytes of data across 12,272 kilometers
from Fairbanks, Alaska to Amsterdam at 401
megabit per second (more than 7,500 times faster than a typical
computer modem) using the networking capabilities of the Pacific
Northwest Gigapop, an access point to leading-edge networks; the
Internet2 Abilene backbone network; StarLight, the advanced optical
infrastructure and proving ground in Chicago, Illinois; and SURFnet.
The Internet 2 Land Speed Record (I2-LSR) competition for the highest
bandwidth, end-to-end networks is an open and ongoing contest.

Angela Spinazze writes to raise awareness of developments on the Handscape Project and promises more for our next issue.

CIMI [1] is pleased to present Handhelds in the Museum Landscape, a symposium on museums and the use of mobile computing devices, to be held on the 24th of June 2002.
In the first of a three-year investigation into potential usage scenarios for mobile computing in museums, CIMI's Handscape project has begun to produce a road map to understanding how mobile technologies can be used by museums to enhance the visitor's experience [2].
The Handscape Project is supported by a grant from Intel Corporation; evaluation activities are directed by the Human Computer Interaction Group at Cornell University, led by Dr. Geri Gay [3]. Three museums with diverse experiences developing and deploying hand held applications have contributed to the initial research. They are The American Museum of the Moving Image (Astoria, New York, USA), Field Museum (Chicago, Illinois, USA) and the Royal Botanic Gardens, Kew (London, England).
The symposium, hosted by Intel at the Jones Farm Conference Center in Hillsboro, Oregon will focus on the results of the first year of research under the grant. It will also highlight applications currently in use by museums, developments in industry and and it will take a look into the future. For more information visit the symposium page [4].
A full symposium report will be presented in the next issue of Cultivate.
