  3. Data Standards • Avoid a combinatorial explosion of data content, description, and metadata arrangements for information storage, access and interchange. Data standards and metadata registries can help.

  6. Metadata RegistriesSemantics Management Evolution • Database (schema) integration • System design • Data use - metadata • Warehouse support – schema and metadata • XML support (schema) • “Backed into” terminology support • Next: Semantics servers -- for semantics web and semantics based computing

  17. Purpose of XMDR • Extend Semantics Management Capabilities of ISO/IEC 11179 • Test & Demo Extended Capabilities in a Reference Implementation • Produce Design for Next Generation Operational 11179 Registries • Propose Revisions to 11179 Parts 2 & 3 (Ver. 3) • Adapt & Adopt Emerging (Semantic) Technologies • Help Resolve Registration & Interrelation Issues for Complex Metadata Standards Forging Semantics Based Computing

  18. Project Background • Collaborative, Interagency Effort • DOD, EPA, LBNL, USGS, NCI, Mayo Clinic…Others? • Draws on and Contributes to Interagency/International Cooperation on Ecoinformatics • Involves International, National, State, Local Government Agencies, other Organizations • Recognizes Great Potential of Semantics-based Computing, Management of Metadata • Improving Collection, Maintenance, Dissemination, Processing of Very Diverse Data Structures • Collaboration Arises from Need to Share Diverse Data Across Multiple Organizations • Project Duration Expected to be July 04 – Jun 05, + Many Players, Many Interests…Shared Context

  19. Concept Of Operations • Service Oriented Architecture • Enables Heterogeneous, Disparate Systems to Interoperate • Agreement in the Interface, Not the Implementation • Publish, Find, Bind • Standards Based Design • Lifecycle Application Support • Abstract Technology Commonalities • Open Standards, Technology Agnostic • Durable: Used for Current and Future Technologies • Semantic Web Service • Publish, Find, Bind…Automatically • Component of Semantic Web • Bootstrap Semantic Web?

  20. Major Tasks, Deliverables & Milestones

  21. Potential Standards/Technologies • DBMS • Object, XML, Relational, RDF/Graph, Logic, Text, Document, Multimedia • Knowledge Representation • Web Ontology Language (OWL) • Simple Common Logic (SCL) • Middleware/Messaging • Cocoon 2, Jini, CoABS, JMS, XMLBlaster, SOAP • XML [Semantic] Web Services • Axis, JWSDP • Agent Development • ABLE, JADE • Engines/Servers • OMS (IBM), Federator/OMS (OWI) • Jess
