  2. Registry Context • Database of “words” • Registry is perhaps the wrong word? • Management of semantics that are declared on the web • Dictionary? Encyclopedia? • User Interface on the Database • Implemented using EOR Toolkit • Registry is independent of EOR • Open Standards • Prototype system

  3. EOR Toolkit • EOR Extensible Open Rdf Toolkit • Stock Open Source Toolbox • Sergey Melnik’s Stanford RDF API (SirPAC) • EOR Glue, Query API, rendering, etc. • MySQL, Apache, Jakarta • Toolkit provides • DB Management, Infuse, Aggregate, Query, Manage and Display RDF/XML data • Facilitate rapid development of RDF Applications

  4. EOR Toolkit (Cont.) • Generic Model • Java • Servlet as session control • JavaBeans as presentation logic • JSP to provide dynamic nature of requested documents • Dublin Core Open Source Licence

  5. Registry Application • Infuse and manage semantics defined by the DCMI activities • DCES, DCQ, DCED, DCType, Agents, Marc Relators for DC, etc. • RDF as a common means of declaring these semantics • Functions • Discover and navigate semantics and understand various relationships to other semantics • Annotate semantics • “DC- Usage endorses dc:title”, etc.

  6. Registry Demonstration • http://wip.dublincore.org

  7. Future Plans • Better annotation support • “Show me all… endorsed by…” • Open Issues: Who can say what about these semantics? • Different interfaces • Machine to human • Application Profiles

  8. Conclusion • DCMI Registry Working Group • DCMI Open Registry Prototype • http://wip.dublincore.org • EOR Toolkit • http://eor.dublincore.org
