  1. Metadata Standards:FGDC and ISO Sharon Shin Federal Geographic Data Committee Metadata Coordinator

  2. Why Standards? • Allows communication between peers • Minimizes data integration time … costs • Permits applications to operate under known conditions

  3. Standards Organizations • International Organization of Standarization (ISO-TC 211) • National Standards Organizations • American National Standards Institute • National Institute of Standards and Technology • FGDC- Established standards with concensus from fed, Tribal, state, and local govts, academia

  4. Roles of Consensus Standards Organizations • ISO provides general purpose standards and specifications as guidance to implementation • National/Community groups define common practices, content, and interaction within and outside the group

  5. Why Metadata Allows agencies to: • Organize and maintain an organization's data investment • Share data set information through data catalogs and clearinghouses • Provide access for download or display and analysis through web services

  6. Why Metadata • Allows users to • discover, • evaluate, • access geodata resources

  7. And… ISO Metadata • ISO 19115 • UML/ abstract model • ANSI adoption 12/24/2003 • ISO 19139 • XML model • Implementation Standard (ISO 19115) • http://metadata.dgiwg.org/index.ht • Community review- Spring/summer 2004 • Technical Specification designation November/December 2004

  8. ISO advantages over CSDGM • Controlled vocabularies- Code Lists • Multi-lingual • Granularity • Feature level metadata

  9. FGDCContent Standard for Digital Geospatial Metadata Metadata content: • identification: Developer, purpose, • quality: processes, methods, accuracy • geography and spatial and temporal schema • spatial reference,and • distribution of digital geographic data.

  10. Dataset Title Reference Date Responsible Party Geographic location Bounding box OR Geographic indentifier Language Characterset Topic Category Scale Abstract Format Name Version Extent Vertical Temporal Representation Type Reference System Lineage On-line Resource Core ISO Metadata Metadata Reference Elements

  11. Participate in ISO 19139 public review. Enter ISO theme keyword into new and existing metadata ENTER WEB ADDRESS HERE ISO 19139 ImplementationWhat to do now

  12. Crosswalk- Conversion Tool Includes ISO and FGDC DTD • http://www.fgdc.gov/CrossWalk/ISO-FGDC- • METADATA-CROSSWALK-V4.xls

  13. What’s Next • US National Metadata Profile • Thematic leads for each FGDC profile/extension • Each team recruits expert support team • Makes recommendations for additions to ISO 19139. • US Profile development follows ISO 19139 adoption time line, coincident development.

  14. FGDC ISO 19139 Implementation Proposed Training Support • Develop FGDC CSDGM Version 3 workbook • Develop base training materials and post to fgdc.gov • Provide implementation assistance / training.
