  1. The Dublin Core Metadata Initiative Makx Dekkers, Managing Director, Dublin Core Metadata Initiative mail@makxdekkers.com

  2. DCMI Overview • Virtual organisation – not incorporated • Hosted by OCLC (Dublin Ohio, USA): personnel, Web site, travel • Other funding through projects and grants • Work is mostly done by volunteers around the world

  3. Mission statement • Develop metadata standards for cross-domain discovery • Define frameworks for interoperability of metadata sets • Facilitate community- or disciplinary-specific metadata sets consistent with 1 and 2

  4. Activities • Standards development and maintenance • Support for development of tools, services and infrastructure • Educational outreach • Community liaison

  5. Dublin Core Metadata • Flat model of 15 base elements • Title, Creator, Contributor, Publisher, Subject, Description, Identifier, Date, Language, Type, Format, Coverage, Source, Relation, Rights • Additional detail through qualifiers • Element refinements, e.g. Date.Created, Relation.IsPartOf • Encoding schemes, e.g. URI, W3CDTF, LCSH, IMT, TGN • Extensions • e.g. Audience element (Education, Libraries and Government), Audience.Mediator qualifier

  6. DCMI Namespaces • Dublin Core 1.1 • http://purl.org/dc/elements/1.1/ • New elements, qualifiers • http://purl.org/dc/terms/ • Controlled vocabularies • http://purl.org/dc/dcmitype/ • http://purl.org/dc/<vocab>/

  7. Governance • DCMI Directorate: • Executive Director: Stuart Weibel, USA • Managing Director: Makx Dekkers, Luxembourg • DCMI Board of Trustees: policy oversight • DCMI Advisory Board: technical experts • DCMI Usage Board: responsible for Metadata Term Semantics

  8. Board of Trustees • Denise BEDFORD, Worldbank • Joseph BUSCH, Interwoven Inc., USA • Michael CRANDALL, Bill & Melinda Gates Foundation • Lorcan DEMPSEY, OCLC, USA • Juha HAKALA, University of Helsinki, Finland • Nathalie LEROY, United Nations • Neil MCLEAN, IMS Australia • Nigel OXBROW, TFPL Ltd., UK • Shigeo SUGIMOTO, ULIS, Japan

  9. Participation • Community of 1 500 practitioners from 1 000 organisations in 50 countries • 17 active working and interest groups • Some 75 active participants (chairs, authors/editors, reviewers) • Domains: (digital) libraries, education, government, business

  10. Some recent news • Z39.85 (DC 1.1): US Standard 2001 • Several e-government programmes adopt DC (AU, CA, DK, FI, IE, NZ, UK), more to follow • EU activity MIReG develops DC-based EU Government Metadata Framework (planned for Summer 2002)

  11. Implementations • Open Archives Initiative • Internal knowledge management in international corporations • Information management in NGOs • Many Digital Libraries projects in US, EU, Austalia, Japan and South-East Asia • Open Source and commercial tools

  12. Main subjects • Expressing Dublin Core metadata in (X)HTML, XML, RDF/XML, etc. • Domain-specific extensions and usage (Application Profiles) • The DCMI Registry (dictionary) • Citations, Agents, Collections • Support for development of tools

  13. Main challenges • Sustainable organisation • Link to Knowledge Management and Technology industry • Official standardisation (ISO fast-track process being planned) • Cross-standard interoperability (OAI, W3C, IEEE/LOM underway, others?)

  14. Co-operation • Cross-standard interoperability • IEEE/Learning Object Metadata: common principles • EU Metadata Interoperability Forum • Standards Registry Committee • Registry activities • W3C RDF Registry demonstrator with IEEE/LOM, AGLS, FAO, others

  15. DC-2002 Florence, Italy • Metadata for e-Communities: Supporting Diversity and Convergence • 13-17 October 2002 • Tutorials, Conference, Workshop • Call for papers closes 15 June 2002 • Preliminary programme July 2002

  16. DC-2002 Florence • Topics • Domain specific metadata usage: education, cultural heritage, e-Government • Search engines and metadata • Knowledge management • Commerce and intranets • Indexing, metadata and ontologies • Tools for metadata interoperability

  17. Outlook • Further develop specifications, best practice and guidance materials • Extend and sustain global network of implementors • Co-operate with other metadata standardisation activities • Contribute to Semantic Web and Knowledge Technologies
