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 ….

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

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 ServicesE.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

XMDR Project Collaboration

Collaborative, interagency effort EPA, USGS, NCI, Mayo Clinic, DOD, LBNL

…& othersDraws on and contributes to

interagency/International Cooperation on Ecoinformatics

Interacts with many organizations around the world through ISO/IEC standards committees

Where does this fit with Ecoterm?

Ecoterm organizations as sources of contentEcoterm organizations as

collaborators/testersEcoterm organizations as potential users of

Open Source software Potential collaboration on R&D projects
