Platform Keyword Facet Search Refinement and GCMD Platform Keyword Changes

What’s Happening:

All changes will be published on March 16, 2022.

Changes to the CEOS IDN, SOOS, AMD Portals

  • Enhanced Platform Facet Search Refinement
    • A more finely-grained query refinement enables users to locate the desired Platform faster resulting in more precise search results.

Changes to the GCMD Keywords (KMS) Platform Keyword Hierarchy

  • Added New Top Level Keyword: "Basis"
  • Added 6 new Keywords at the "Basis" level: 
    • Air-based Platforms
    • Land-based Platform
    • Living Organism-based Platforms
    • Other
    • Space-based Platforms
    • Water-based Platforms
  • Renamed and Expanded the "Category" Level
  • Renamed "Series_Entity" Level to "Sub_Category"

    Note: Sub_Category keywords are only listed for Buoys, Fixed Platforms, Vessels, Uncrewed Vehicles. Please download the CSV file to view the full list of Platform Sub_Category Keywords)

    • Air-based Platforms

      • Balloons
      • Dropwindsondes
      • Jet
      • Propeller

      • Navigation Satellites
      • Solar/Space Observation Satellites
      • Space Stations/Crewed Spacecraft
    • Water-based Platforms

  • Modified some "Sub_Category" (formerly "Series_Entity") Keywords for constancy.
    • Old: DMSP(Defense Meteorological Satellite Program)
    • New: Defense Meteorological Satellite Program (DMSP)
    • Example
  • Draft of the new Platform Keywords (CSV)
  • KMS RESTful (KMS)
    • Modified KMS RESTful CSV Output for new column headers
      • Old:               Category | Series_Entity   | Short_Name   | Long_Name   | UUID

      • New: Basis | Category | Sub_Category | Short_Name   | Long_Name   | UUID
  • GCMD Keyword Viewer (GKV)
    • Supports the new Platform Hierarchy.

Action Needed:

  • No Action needed for portals.
  • Metadata curators creating new metadata must use the new "Category" values in the UMM-C/PlatformType "Type" field (if Cmr-Validate-Keywords=True)Cmr-Validate-Key
    • Support for new "Type" keywords is built in if you use MMT or dMMT to create a new collection.
    • Example: Platform Keyword with old value and with new value

      ECHO-10 -

      Old:

      <Platforms>
      <Platform>
      <ShortName>NASA DC-8</ShortName>
      <LongName>NASA Douglas DC-8</LongName>
      <Type>Aircraft</Type>
      <Instruments>
      <Instrument>
      <ShortName>Cameras</ShortName>
      </Instrument>
      </Instruments>
      </Platform>
      </Platforms>

      New:

      <Platforms>
      <Platform>
      <ShortName>NASA DC-8</ShortName>
      <LongName>NASA Douglas DC-8</LongName>
      <Type>Jet</Type>
      <Instruments>
      <Instrument>
      <ShortName>Cameras</ShortName>
      </Instrument>
      </Instruments>
      </Platform>
      </Platforms>

  • Metadata curators updating existing metadata where the "Category" values in the UMM-C/PlatformType "Type" field have changed can update their metadata over time as Progressive Update permits ingest of metadata with existing errors (for as long as new errors are not introduced).
