The Semantic Web activity is a W3C project whose goal is to enable a 'cooperative' Web where machines and humans can exchange electronic content that has clear-cut, unambiguous meaning. This vision is based on the automated sharing of metadata terms across Web applications. The declaration of schemas in metadata registries advance this vision by providing a common approach for the discovery, understanding, and exchange of semantics. However, many of the issues regarding registries are not clear, and ideas vary regarding their scope and purpose. Additionally, registry issues are often difficult to describe and comprehend without a working example.

Phrases
<P1> Establishing a common approach for the exchange and re-use of data across the Web would be a major step towards achieving the vision of the Semantic Web. <warrant> <P2> The Semantic Web Activity statement articulates this vision as: 'having data on the Web defined and linked in a way that it can be used for more effective discovery, automation, integration, and reuse across various applications. The Web can reach its full potential if it becomes a place where data can be shared and processed by automated tools as well as by people.' <P3> In parallel with the growth of content on the Web, there have been increases in the amount and variety of metadata to manipulate this content. An inordinate amount of standards-making activity focuses on metadata schemas (also referred to as vocabularies or data element sets), and yet significant differences in schemas remain. <P4> Different domains typically require differentiation in the complexity and semantics of the schemas they use. Indeed, individual implementations often specify local usage, thereby introducing local terms to metadata schemas specified by standards-making bodies. Such differentiation undermines interoperability between systems. <P5> This situation highlights a growing need for access by users to in-depth information about metadata schemas and particular extensions or variations to schemas. Currently, these 'users' are human  people requesting information. <warrant> <P6> It would be helpful to make available easy access to schemas already in use to provide both humans and software with comprehensive, accurate and authoritative information. <warrant> <P7> The W3C Resource Description Framework (RDF) has provided the basis for a common approach to declaring schemas in use. At present the RDF Schema (RDFS) specification offers the basis for a simple declaration of schema. <P8> Even as it stands, an increasing number of initiatives are using RDFS to 'publish' their schemas. <P9> Registries provide 'added value' to users by indexing schemas relevant to a particular 'domain' or 'community of use' and by simplifying the navigation of terms by enabling multiple schemas to be accessed from one view. <warrant> <P10> Additionally, the establishment of registries to index terms actively being used in local implementations facilitates the metadata standards activity by providing implementation experience transferable to the standards-making process. <warrant> <P11> The overriding goal has been the development of a generic registry tool useful for registry applications in general, not just useful for the DCMI. <P12> The formulation of a 'definitive' set of RDF schemas within the DCMI that can serve as the recommended, comprehensive and accurate expression of the DCMI vocabulary has hindered the development of the DCMI registry. To some extent, this has been due to the changing nature of the RDF Schema specification and its W3C candidate recommendation status. However, it should be recognized that the lack of consensus within the DCMI community regarding the RDF schemas has proven to be equally as impeding. <P13> The automated sharing of metadata across applications is an important part of realizing the goal of the Semantic Web. Users and applications need practical solutions for discovering and sharing semantics. Schema registries provide a viable means of achieving this. <warrant>
Conclusions
RQ "Many of the issues regarding metadata registries are unclear and ideas regarding their scope and purpose vary.

D6.2 Impact on World-wide Metadata Standards Report
This document presents the ARTISTE three-level approach to providing an open and flexible solution for combined metadata and image content-based search and retrieval across multiple, distributed image collections. The intended audience for this report includes museum and gallery owners who are interested in providing or extending services for remote access, developers of collection management and image search and retrieval systems, and standards bodies in both the fine art and digital library domains.
Notes
ARTISTE (http://www.artisteweb.org/) is a European Commission supported project that has developed integrated content and metadata-based image retrieval across several major art galleries in 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.

<CA>  Over the last two and a half years, ARTISTE has developed an image search and retrieval system that integrates distributed, heterogeneous image collections. This report positions the work achieved in ARTISTE with respect to metadata standards and approaches for open search and retrieval using digital library technology. In particular, this report describes three key aspects of ARTISTE: the transparent translation of local metadata to common standards such as Dublin Core and SIMI consortium attribute sets to allow cross-collection searching; A methodology for combining metadata and image content-based analysis into single search galleries to enable versatile retrieval and navigation facilities within and between gallery collections; and an open interface for cross-collection search and retrieval that advances existing open standards for remote access to digital libraries, such as OAI (Open Archive Initiative) and ZING SRW (Z39.50 International: Next Generation Search and Retrieval Web Service).
Conclusions
RQ "A large part of ARTISTE is concerned with use of existing standards for metadata frameworks. However, one area where existing standards have not been sufficient is multimedia content-based search and retrieval. A proposal has been made to ZING for additions to SRW. This will hopefully enable ARTISTE to make a valued contribution to this rapidly evolving standard." ... "The work started in ARTISTE is being continued in SCULTEUR, another project funded by the European Commission. SCUPLTEUR will develop both the technology and the expertise to create, manage, and present cultural archives of 3D models and associated multimedia objects." ... "We believe the full benefit of multimedia search and retrieval can only be realised through seamless integration of content-based analysis techniques. However, not only does introduction of content-bases analysis require modification to existing standards as outlines in this report, but it also requires a review if the use of semantics in achieving digital library interoperability. In particular, machine understandable description of the semantics of textual metadata, multimedia content, and content-based analysis, can provide a foundation for a new generation of flexible and dynamic digital library tools and services. " ... "Existing standards do not use explicit semantics to describe query operators or their application to metadata and multimedia content at individual sites. However, dynamically determining what operators and types are supported by a collection is essential to robust and efficient cross-collection searching. Dynamic use of published semantics would allow a collection and any associated content-based analysis to be changed  by its owner without breaking conformance to search and retrieval standards. Furthermore, individual sites would not need to publish detailed, human readable descriptions of available functionality.

RLG Best Practice Guidelines for Encoded Archival Description
These award-winning guidelines, released in August 2002, were developed by the RLG EAD Advisory Group to provide practical, community-wide advice for encoding finding aids. They are designed to: facilitate interoperability of resource discovery by imposing a basic degree of uniformity on the creation of valid EAD-encoded documents; encourage the inclusion of particular elements, and; develop a set of core data elements.

<CA> The objectives of the guidelines are: 1. To facilitate interoperability of resource discovery by imposing a basic degree of uniformity on the creation of valid EAD-encoded documents and to encourage the inclusion of elements most useful for retrieval in a union index and for display in an integrated (cross-institutional) setting; 2. To offer researchers the full benefits of XML in retrieval and display by developing a set of core data elements to improve resource discovery. It is hoped that by identifying core elements and by specifying "best practice" for those elements, these guidelines will be valuable to those who create finding aids, as well as to vendors and tool builders; 3. To contribute to the evolution of the EAD standard by articulating a set of best practice guidelines suitable for interinstitutional and international use. These guidelines can be applied to both retrospective conversion of legacy finding aids and the creation of new finding aids.

There are many types of standards used to manage museum collections information. These "standards", which range from precise technical  standards to general guidelines, enable museum data to be efficiently  and consistently indexed, sorted, retrieved, and shared, both  in automated and paper-based systems. Museums often use metadata standards  (also called data structure standards) to help them: define what types of information to record in their database  (or card catalogue); structure this information (the relationships between the  different types of information). Following (or mapping data to) these standards makes it possible  for museums to move their data between computer systems, or share  their data with other organizations.

This is one of a series of guides produced by the Cedars digital preservation project. This guide concentrates on the technical approaches that Cedars recommends as a result of its experience. The accent is on preservation, without which continued access is not possible. The time scale is at least decades, i.e. way beyond the lifetime of any hardware technology. The overall preservation strategy is to remove the data from its medium of acquisition and to preserve the digital content as a stream of bytes. There is good reason to be confident that data held as a stream of bytes can be preserved indefinitely. Just as there is no access without preservation, preservation with no prospect of future access is a very sterile exercise. As well as preserving the data as a byte-stream, Cedars adds in metadata. This includes reference to facilities (called technical metadata in this document) for accessing the intellectual content of the preserved data. This technical metadata will usually include actual software for use in accessing the data. It will be stored as a preserved object in the overall archive store, and will be revised as technology evolves making new methods of access to preserved objects appropriate. There will be big economies of scale, as most, if not all, objects of the same type will share the same technical metadata. Cedars recommends against repeated format conversions, and instead argues for keeping the preserved byte-stream, while tracking evolving technology by maintaining the technical metadata. It is for this reason that Cedars includes only a reference to the technical metadata in the preserved data object. Thus future users of the object will be pointed to information appropriate to their own era, rather than that of the object's preservation. The monitoring and updating of this aspect of the technical metadata is a vital function of the digital library. In practice, Cedars expects that very many preserved digital objects will be in the same format, and will reference the same technical metadata. Access to a preserved object then involves Migration on Request, in that any necessary migration from an obsolete format to an appropriate current day format happens at the point of request. As well as recommending actions to be taken to preserve digital objects, Cedars also recommends the use of a permanent naming scheme, with a strong recommendation that such a scheme should be infinitely extensible.

The CDISC Submission Metadata Model was created to help ensure that the supporting metadata for these submission datasets should meet the following objectives: Provide FDA reviewers with clear describtions of the usage, structure, contents, and attributes of all datasets and variables; Allow reviewers to replicate most analyses, tables, graphs, and listings with minimal or no transformations; Enable reviewers to easily view and subset the data used to generate any analysis, table, graph, or listing without complex programming. ... The CDISC Submission Metadata Model has been defined to guide sponsors in the preparation of data that is to be submitted to the FDA. By following the principles of this model, sponsors will help reviewers to accurately interpret the contents of submitted data and work with it more effectively, without sacrificing the scientific objectives of clinical development.

CA "The main problem surrounding the preservation of authentic electronic records is that of technology obsolescence. As changes in technology continue to increase exponentially, the problem arises of what to do with records that were created using old and now obsolete hardware and software.

Conclusions
RQ "The Testbed will be conducting research to discover if there is an inviolable way to associate metadata with records and to assess the limitations such an approach may incur.

Report of the Ad Hoc Committee for Development of a Standardized Tool for Encoding Finding Aids
This report focuses on the development of tools for the description and intellectual control of archives and the discovery of relevant resources by users. Other archival functions, such as appraisal, acquisition, preservation, and physical control, are beyond the scope for this project. The system developed as a result of this report should be useable on stand-alone computers in small institutions, by multiple users in larger organisations, and by local, regional, national, and international networks. The development of such a system should take into account the strategies, experiences, and results of other initiatives such as the European Union Archival Network (EUAN), the Linking and Exploring Authority Files (LEAF) initiative, the European Visual Archives (EVA) project, and the Canadian Archival Information Network (CAIN). This report is divided into five sections. A description of the conceptual structure of an archival information system, described as six layers of services and protocols, follows this introduction. Section three details the functional requirements for the software tool and is followed by a discussion of the relationship of these requirements to existing archival software application. The report concludes with a series of recommendations that provide a strategy for the successful development, deployment, and maintenance of an Open Source Archival Resource Information System (OSARIS). There are two appendices: a data model and a comparison of the functional requirements statements to several existing archival systems.

Critical Arguements
CA The Ad Hoc Committee agrees that it would be highly desirable to develop a modular, open source software tool that could be used by archives worldwide to manage the intellectual control of their holdings through the recording of standardized descriptive data. Individual archives could combine their data with that of other institutions in regional, national or international networks. Researchers could access this data either via a stand-alone computerized system or over the Internet. The model for this software would be the successful UNESCO-sponsored free library program, ISIS, which has been in widespread use around the developing world for many years. The software, with appropriate supporting documentation, would be freely available via an ICA or UNESCO web site or on CD-ROM. Unlike ISIS, however, the source code and not just the software should be freely available.
Conclusions
RQ "1. That the ICA endorses the functional requirements presented in this document as the basis for moving the initiative forward. 2. That the functional desiderata and technical specifications for the software applications, such as user requirements, business rules, and detailed data models, should be developed further by a team of experts from both ICA/CDS and ICA/ITC as the next stage of this project. 3. That following the finalization of the technical specifications for OSARIS, the requirements should be compared to existing systems and a decision made to adopt or adapt existing software or to build new applications. At that point in time, it will then be possible to estimate project costs. 4. That a solution that incorporates the functional requirements result in the development of several modular software applications. 5. That the implementation of the system should follow a modular strategy. 6. That the development of software applications must include a thorough investigation and assessment of existing solutions beginning with those identified in section four and Appendix B of this document. 7. That the ICA develop a strategy for communicating the progress of this project to members of the international archival community on a regular basis. This would include the distribution of progress reports in multiple languages. The communication strategy must include a two-way exchange of ideas. The project will benefit strongly from the ongoing comments, suggestions, and input of the members of the international archival community. 8. That a test-bed be developed to allow the testing of software solutions in a realistic archival environment. 9. That the system specifications, its documentation, and the source codes for the applications be freely available. 10. That training courses for new users, ongoing education, and webbased support groups be established. 11. That promotion of the software be carried out through the existing regional infrastructure of ICA and through UNESCO. 12. That an infrastructure for ongoing maintenance, distribution, and technical support be developed. This should include a web site to download software and supporting documentation. The ICA should also establish and maintain a mechanism for end-users to recommend changes and enhancements to the software. 13. That the ICA establishes and maintains an official mechanism for regular review of the software by an advisory committee that includes technical and archival experts. "
