  1. DoD Metadata Registry Presentation to Federal Data Architecture Subcommittee Dr Glenda Hayes MITRE/DISA PEO-GES 9 Oct 2008

  2. Agenda • Net-Centricity • DoD Net-Centric Data Strategy • What is Metadata? • Structural and Semantic Metadata • Discovery Metadata • DoD Metadata Registry and Clearinghouse (DoD MDR)

  3. Net-Centric Tenets DoD Net-Centric Data Strategy Information Assurance Strategy Core Enterprise Services (NCES) Global Connectivity (Transformational Communications) Recipe for Agility

  4. DoD Net-Centric Data Strategy The DoD Net-Centric Data Strategy, issued by the DoD CIO May 9, 2003, is the plan to make the Department’s information resources: Is an information resource discoverable by most users? Visible Is it available on the network, and are tools readily available to use it? Accessible Can it be intelligibly used? Are the semantics well documented? Understandable Are the source, security level and access controls of the data available to users? Trusted Can it be combined or compared with other information? Can it be mediated? Interoperable Is the data what users need? Are robust user feedback mechanisms in place to improve it? Responsive CC/S/As must institutionalize processes to accomplish these goals 4

  5. Quiz: Which of these is Metadata?           • An XML Schema? A WSDL? • A database structure? • A picklist? • An index card in the library? • MS-Office product’s properties? • Email classification and release conditions? • Notes on the back of a photo? • iPod playlist? • Date and reviewer for a taxonomy? • Product ratings & comments on Amazon?

  7. Mission Provide tools, techniques, and performance standards to enable the DoD Data Strategy Support DISA DoD Data Strategy compliance effort Products & Services Chair DoD Metadata Working Group Provide NCES Metadata Services support Oversee operation of the DoD Metadata Registry Develop and promote Data Strategy Enablers for Communities of Interest (COIs) Provide Data Strategy input to NCES Acquisition Milestone Documents Support NCES Product Branch, Testing & Evaluation, Operations, Sustainment, and NetOps activities Support DISA CIO in extending the Enterprise Information Environment (EIE) technical procedures and standards for DISA internal systems PEO – GES Data Services Office Additional questions, please use the Comments and Feedback link at

  8. “I need a tank” What does it mean? Make Data Understandable One reason Government Agencies and Military Services have trouble operating jointly is that they speak different languages. Registering and using taxonomies improves precision search and recall Register Terms, Definitions, & Relationships

  18. DoD Metadata Registry (MDR) Purpose Provide an on-line repository which enables developers to reuse, understand, integrate with, and share existing data assets (metadata) Targeting web services, databases, and vocabularies Mandated for the publishing of semantic and structural metadata DOD Directive 8320.2 Provides a portal for developer access and web services for machine-to-machine access Key Facts Over 8,000 users and 180,000 assets registered Over 900 Programs of Record supported Serving the DoD, DHS, IC, NASA and NATO Hosted on NIPR, SIPR, and JWICS (in progress) User driven via DoD Metadata Working Group and Feedback links Implements the ebXML standard for Metadata Registries (in DISR) User Name/Password or Single Sign-On through DKO Governance structure provided by Joint Enterprise Services ERB Primary Benefits Enables reuse and governance of data assets Foundation for other services; e.g. mediation Allows the COI data assets to exist after the COI disbands Primary Audience DoD Capability Developers, COIs

  19. DoD MDR History DoD XML Registration Memo MDR Implements ebXML RIM & RS DoD Metadata Registry MDR on SIPR COE XML Registry v6.1 v7.0 v5.0 v2.1 v4.1 v3.1 v1.0 2000 2002 2004 2006 2008 IC Info Sharing Data Standards Coordination Activity (DSCA )

  20. MDR Users • Developers • Re-use and subscribe to registered data components, and/or register new ones they have created • Community of Interest (COI) Metadata Governors • Configuration Manage (CM) registered component (e.g., posting new metadata versions, version change notification etc.) • Acquisition Policy Makers • Use Metadata Registry metrics for acquisition oversight (e.g., reflecting program participation, specific data component re-use etc.) • Applications • Interface with registered components via Metadata Registry Web Service (ebXML) to exploit reference tables, transformations, and XML schemas at Run Time

  21. MDR Size and Scope • Instances on 2 security enclaves • Unclassified and Secret • Users – 10,186 • Information Resources • Submission Package – 1,263 • Schemas (e.g., DTD, XSD, etc) – 4,814 • Translations (i.e., XSL, XSLT) – 180 • Services (i.e., WSDL) – 555 • XML samples – 251 • Taxonomies (i.e., OWL) – 178 • Reference Data Sets – 5,709 • Amplifying Documents (e.g., DOC, ER1, etc) – 5,268 • 900 Programs of Record, 700 Organizations Unclassified MDR Inventory as of 8 Oct 2008

  22. Making Data Visible, Accessible, and Understandable through Metadata Federated Search Interface NCES Enterprise Catalog Defense Online warfighter 3 Register discovery metadata IAW DDMS in Federated Search-enabled Catalog Audience: warfighter, intelligence, business user Audience: developer, application program NCES Service Registry 2 Register service metadata & endpoints Uses registered resources developer Web Interface (HCI) 1 DoD Metadata Registry Construct & Submit Package to MDR.

  42. Differentiating Types of Metadata Structural & Semantic Metadata “Rules governing a chunk” - Name, description, data constraints, and relationships of tags used in information resources to delimit one chunk of data from another chunk Artifacts where structural metadata is described: XML schemas, RDBMS structures, taxonomies Register in DoD Metadata Registry, use submission pkg Resource Metadata “Advertisement” - Terms to aid in the recall and retrieval of artifacts Artifacts that we collect resource metadata on: PPT, DOC, GIF, JPG, MPG, RDBMS Register in “Data Catalog”, use DoD Discovery Metadata Specification (DDMS)
