  2. Agenda • Overview of current Version 4.1 • Why version 5 • New Features • Standard Support • NCES / Core Service • Notional components • Future Gallery Map

  3. DoD Metadata Registry Portal http://metadata.dod.mil • “One Stop” Publish & Subscribe for: • Build Time Metadata Registration • Pulling Re-usable Data Components • Information Community Management • Now Vending: • Database Segments • Reference Sets • Transformations • XML • Data/Metadata Tools • Taxonomies • More Products soon (e.g., symbology, translations) • Over 3,500 registered users Web-based! Purpose: visibility and re-use, not standardization through mandate!

  4. DoD XML Gallery http://metadata.dod.mil/xmlreg/user - Global Net Access - Pub-Sub Registry - Business Rules - Organizations - Over 80,000 registered components - 86 Namespaces IOC: 19 May 1999 - Current Version = 4.1

  5. Architecture of v4.1Current Version • Home page uses Weblogic Portal • Remaining pages are written in ColdFusion • DB is Oracle • Web server is Netscape Enterprise Developers, Architects, etc. GIG-ES Portal CORE Services GIG-ES Portal Metadata Registry Portal Translations Schemas Transformation Services Web Services REST WS-I XML Gallery Taxonomy Gallery Mediation Engine(s) Reference Data Sets Gallery Database Segments Gallery Data Elements Gallery 3rd Party Portlets BEA Weblogic Server & ColdFusion Oracle DB

  6. 20,000 Foot View DB Segments Assertions XML Schema Taxonomy Data Elements Reference Data Sets Data Models DoD Metadata Registry and Clearinghouse Metrics: User & System Access Re-use Downloads Viewing Search & Discovery HTTP Access Change Notifications Web Service Access Categorization Users Systems

  7. Why version 5.0 • Consolidate COTS products • BEA Portal Platform • Oracle 9i (10g?) • Portals give end user more options • BEA is better suited for run-time services • Core data model for all types of artifact metadata • Increased reliability and uptime via clustering • Part of the NCES Discovery core service • Support other services such as mediation

  8. New Features • Taxonomy gallery • OWL encoded format • Provides capability to tie any information resource to a node in a taxonomy • HTTP access to most artifacts in a W3C compliant manner • Branding • Improved Security • Auditing • Multiple authorization routes • Granular access rights • Federation capability • Portal – end user customization • Additional Web services • Search for all Information Resources • Retrieval for all information Resources

  9. Standards Support • ebXML API compliance • Will have a standard profile for semantic interoperability • JAXR (registry API) • WSRP (Portals) • WS-I (web services)

  10. ebXML compliance ebXML – Registry Services ebXML – Registry Information Model Notional Components MDR Portal XML Portlets Taxonomy Portlets Data Elements Portlets Inter-operate with other NCES portals via WSRP RDS Portlets DB Portlets BEA Auditing and Security Services SIPR and JWICS security accreditation NCES Security - BAH SDK Implement NCES security services (Interchangeable layer) Web Service JAXR API Standard support Leverage Open-Source Oracle RAC Increase reliability and performance MDR v5.0 DB
