  1. Introduction to Geospatial Metadata – FGDC CSDGM National Coastal Data Development Center A division of the National Oceanographic Data Center Please email a list of participants at each location to ncddcmetadata@noaa.gov Also Email questions for the Q&A session to ncddcmetadata@noaa.gov

  2. Series Materials: ftp://ftp.ncddc.noaa.gov/pub/Metadata/Online_ISO_Training/Intro_to_CSDGM/ CSDGM Geospatial Metadata Standards: http://www.fgdc.gov/metadata/geospatial-metadata-standards#csdgm CSDGM Resources

  3. Tailoring Metadata for Your Needs Beyond the basics

  4. Use of Thesauri or Keywords CSDGM Profiles Biological Shoreline CSDGM Extensions Remote Sensing Local Extensions Different Standards Fine Tuning Your CSDGM

  5. Why Tailor? • Can use discipline specific thesauri • CSDGM profile or extension may better fit your dataset • Dataset specific guidelines • Organization or Community guidelines • Publishing or harvesting purposes

  6. What are Thesauri? Discipline specific vocabularies Describes data in a standardized manner Tools in which to manage the knowledge held within resources and the relationships between their entries Goal is to facilitate interoperability and enable data discovery

  7. ISO 19115 Topic Category • International standard for geographic metadata • Topic Categories are used as “Theme” Keywords in FGDC CSDGM

  8. Global Change Master Directory (GCMD) Dynamic lists that evolve to meet changing needs of Earth science community Organized in a hierarchy constructed of Topics, Terms, and Variables

  9. GCMD Keywords

  10. User defined and vetted Consistency between data items Remember….. Spreadsheet example Data Dictionaries

  11. What type of information does a Data Dictionary hold? Precise definition of data elements Domains Stored procedures and triggers General database structure Space allocations

  12. Profiles • Profiles extend the base standard by adding metadata elements to meet their specific community metadata requirements • Examples of profiles of CSDGM: • Biological Data Profile of the CSDGM • Metadata Profile for Shoreline Data

  13. Biological Profile • Objective is to increase the FGDC CSDGM utility for documenting biological resources data and information • Helps broaden the understanding and implementation of the FGDC metadata content standard within the biological resources community

  14. Biological Profile

  15. Shoreline Profile

  16. Extensions • Extensions are used when some data does not fit into a particular section • Example of extensions: • Remote Sensing Extensions include metadata describing the sensor, platform, the information need to determine the geographical location, and the method and process of deriving geospatial information from the raw telemetry

  17. Remote Sensing Extensions

  18. Remote Sensing Extensions

  19. Languages used to categorize, label, and organize data content Community driven (are often discipline specific) Examples include: XML SensorML EML Markup Languages

  20. Different Standards Ecological Metadata Language (EML) MARC21 – MARCXML Dublin Core – DCMI ISO 19115 and related ISO standards

  21. Mapping Standards • Other standards can often be “mapped” or “crosswalked” to compare to FGDC data • Examples • Marc21 • Dublin Core • ISO 19115 or 19915-2

  22. Transforming Metadata This is a part of the mapping for FGDC CSDGM to ISO 19115. Comments are Best Practices or Questions

  23. Transforming Metadata transform ISO 19115 CSDGM Result - an xml instance of an ISO 19115 record. Input - an xml version of a CSDGM record. XSLT Transformation csdgm2iso19115.xslt

  24. How will it affect our metadata?

  25. Know your dataset Know your needs Know your options Thesauri Extensions Profiles Review
