  5. Metadata Registry Extensions • Register (and manage) any semantics that are useful for managing data. • E.g., this may include registering not only permissible values (concepts), definitions, but may extend to registration of the full concept systems in which the permissible values are found. • E.g., may want to register keywords, thesauri, taxonomies, ontologies, axiomatized ontologies…. • Support traditional data management and data administration • Lay Foundation for semantic computing: Semantics Service Oriented Architecture, Semantic Grids, Semantics based workflows, Semantic Web ….

  6. XMDR Project Results • Design for next generation metadata registries, expressed as a standard—ISO/IEC 11179 family of standards • XMDR Prototype, open source software • Semantic content in prototype • Demonstrations for healthcare and the environment • Ecoinformatics test bed • Demonstration using water data and concept systems

  7. XMDR: Register Any Concept System orKnowledge Organization System (KOS) • Keywords • Glossaries • Gazetteers • Thesauri • Taxonomies • Ontologies • Axiomatized Ontologies

  12. Inference Disease is-a is-a Infectious Disease Chronic Disease is-a is-a is-a is-a Heart disease Diabetes Polio Smallpox Signifies inferred is-a relationship

  13. ISO/IEC 11179 Metadata Registries+ XMDR • Register and manage semantics that are or can be harmonized and vetted by some Community of Interest (COI) • Provide Semantic Services • E.g., the semantics can be referenced by RDF statements (subjects, predicates, objects) • The semantics can be used for Semantic Web and Semantic Computing • A “vocabulary” that is grounded for some COI

  15. XMDR Project Collaboration • Collaborative, interagency effort • EPA, USGS, NCI, Mayo Clinic, DOD, LBNL …& others • Draws on and contributes to interagency/International Cooperation on Ecoinformatics • Interacts with many organizations around the world through ISO/IEC standards committees

  16. Where does this fit with Ecoterm? • Ecoterm organizations as sources of content • Ecoterm organizations as collaborators/testers • Ecoterm organizations as potential users of Open Source software • Potential collaboration on R&D projects e.g., under European Commission Framework Program 7 WWW.XMDR.ORG
