  1. The Semantic Web A proposed practical strategy for the DCMI Makx Dekkers, Managing Director, Dublin Core Metadata Initiative mail@makxdekkers.com Dublin Core Workshop, Tokyo

  2. What is the Semantic Web? A vision of possibilities “The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” -- Tim Berners-Lee, James Hendler and OraLassila, The Semantic Web, Scientific American, May 2001 Dublin Core Workshop, Tokyo

  3. Semantic Web aspects • Machines talking to machines - semantics need to be declared • Federating domains - enabling complex tasks based on information from various sources • Wide scope - from home to global • Robust - imperfect understanding That sounds familiar - isn’t that what DCMI tries to achieve, too? Dublin Core Workshop, Tokyo

  4. Semantic Web Architecture Tim Berners-Lee http://www.w3.org/2000/Talks/1206-xml2k-tbl/Overview.html Schemes Metadata Dublin Core Workshop, Tokyo

  5. Semantic Web needs • Conventions about semantics • Conventions about infrastructure • The Web for connectivity • A whole lot of machinery to be developed • Integration of ‘legacy’ solutions at affordable cost Dublin Core Workshop, Tokyo

  6. Semantic Web problems • From vision to implementation: how can it be explained to decision makers? • Leadership: everyone is waiting for the Semantic Web Activity at W3C to tell us what it means in practice • Understanding: how can we begin to create common directions? Dublin Core Workshop, Tokyo

  7. Should we care? • Yes: • Our common, simple metadata language addresses the same vision • We don’t want to find solutions in isolation • We can benefit from industry take-up • But: • There is a risk that the Semantic Web will not fly, and our community cannot afford to fail Dublin Core Workshop, Tokyo

  8. How can we help? • Understanding • Continue to work with a cross-domain focus • Continue to build bridges to other communities • Implementation • Demonstrate practical implementation of some of the technologies • Guidance and best practice documentation • Contribute our experience to W3C Dublin Core Workshop, Tokyo

  9. Proposed DCMI strategy • Priority #1: to meet the practical needs of our community • Monitor Semantic Web developments and use what we can practically apply • Not necessarily push the boundaries; engage in reseach where it helps us • Promote the Dublin Core as the solution for the Semantic Web metadata layer Dublin Core Workshop, Tokyo

  10. Practical steps • Define the Dublin Core terms as an RDF schema (as one of the options) • Build the DCMI Registry on the basis of RDF • Maintain good relations with the Semantic Web activity at W3C • Promote the Dublin Core in the Semantic Web activity, not the other way round (i.e. we should not prescribe the use of RDF) Dublin Core Workshop, Tokyo
