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

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

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

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