  9. WMO approach to metadata • Build on existing standards • WMO • GRIB and BUFR definitions • ISO • 191xx series • Geographic metadata (19115)  • XML representation (19139)  • Open Geospatial Consortium • Catalog service ? Meeting Name

  10. WMO Core Profile • Core metadata: • subset of full standard • most appropriate elements for field • some extensions to cover specific needs Meeting Name

  11. Profile - topics Metadata record Description of the metadata record for the dataset Data Description of the dataset itself WMO Core Profile Usage Restrictions on how the data can be used Quality Quality assurance information Meeting Name

  12. Profile – Metadata Identifier for metadata Date metadata created Language & character set of metadata Metadata standard used Co-ordinate systems used in metadata Metadata record Data Description of the dataset itself WMO Core Profile Usage Restrictions on how the data can be used Quality Quality assurance information Meeting Name
