  1. Merging Metadata Standards: FGDC CSDGM and ISO 19115 and 19139 Sharon Shin Federal Geographic Data Committee Metadata Coordinator sharon_shin@fgdc.gov

  2. Consensus Standards Organizations • ISO provides general purpose standards and specifications as guidance to implementation • American National Standards Institute • INCITS L-1: ANSI’s geospatial standards body • FGDC- US Geospatial Metadata Standards body- Established standards with concensus from fed, Tribal, state, and local govts, academic

  3. Why Standards? • Interoperability- Allows communication between peers • Minimizes data integration time … costs • Permits data operations under known conditions

  4. FGDC Metadata Content • Identification • Data Quality • Spatial Representation • Spatial reference system • Entities/Attributes • Distribution • Metadata Reference • Temporal information

  5. ISO Metadata • ISO 19115 • UML abstract model • ANSI adoption 12/24/2003 • Based on content from various national metadata standards including FGDC

  6. 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

  7. ISO advantages over CSDGMCode Lists • Citation Role Code (Responsible Party a repeatable field) • Resource Provider • Custodian • Owner • Distributor • Originator • Point of Contact • Principal Investigator • Processor • Publisher • Author

  8. MD_Metadata heirarchyLevel MD_ScopeCode MD_ScopeCode 001 attribute 002 attributeType 005 dataset 006 series 007 nonGeographicDataset 009 feature 010 featureType 013 service 014 model Metadata Hierarchies

  9. FGDC’s US Profile Activities • US National Metadata Profile • Convened metadata experts • FGDC CSDGM • Biological Data Profile • Shoreline Metadata Extension • Maked recommendations for extensions additions to ISO 19139. • US Profile development follows ISO 19139 adoption time line, coincident development.

  10. Document Review • ISO 19115 Metadata Standard (UML) • FGDC-ISO 19115 Crosswalk • http://www.fgdc.gov/CrossWalk/ISO-FGDC- METADATA-CROSSWALK-V4.xls • ISO 19108 Temporal Schema • ISO 19109 Rules for Schema • ISO 19110 Feature Catalog • ISO 19139 Metadata Implementation Standard (XML)

  11. ISO 19139 • ISO 19139 • XML model • Implementation Standard (ISO 19115) • http://metadata.dgiwg.org/index.ht • Community review- Spring/summer 2004 • Technical Specification designation Winter 2004-2005 • September 8, collection of 19139 comments • Public Review comments submission to IS0, through ANSI-L1 by September 30, 2004 • Register at metadata.dgiwg.org • Download ISO 19139, 19115 • “Winter 2004-2005” ISO adoption.

  12. FGDC-US Profile Activities • “No Matches” in FGDC-ISO crosswalk • Extend existing content • Deprecate 1 FGDC element • Distance and Bearing • Biological Content • Taxonomy covered by ISO 19139 • Extend content • General Taxonomic Description • Shoreline extension review status: in process

  13. TimePeriod Beginning/Ending Dates Ex_Extent (Temporal Schema ISO 19108) TMPosition (data value) Begin: TM_Position End: TM_Position No Match Example hhh

  14. Absissa and Ordinate Resolution MD_Dimension MD_VectorSpatial Representation Extend with VectorResolution with MD_Dimension, Max Occurance = 2 Value Extension Example

  15. What’s Next:Crosswalk- Conversion Tool • Content aligned with ISO 19139 • Stand alone application • Free, download from fgdc.gov

  16. What’s Next:Metadata Profile • Follow FGDC Standards Coordinator guidance for US National Profile review. • Through collaboration with Canadian metadata develop content agreeable to both countries - arrive at North American Metadata Profile. • Participation with Mexico’s metadata agencies under negotiation. If aggreement reached, US, Canada, Mexico North American Profile

  17. What’s Next:FGDC Metadata Training Materials • Develop FGDC CSDGM Version 3 workbook • Develop base training materials and post to fgdc.gov • Provide implementation assistance / training.
