The UMM-Collection Profile consists of metadata concepts considered important for describing CMR data collections. The UMM-Collection Profile includes required, recommended and optional concepts. Required concepts must be included in UMM-compliant CMR metadata records.
The goal of this effort is to help NASA Data Centers provide full support for the UMM-Collection Profile through the evaluation and reporting of metadata completeness with respect to the UMM-Collection Profile. The following CMR Collection were considered in this evaluation.
- Alaska Satellite Facility (ASF)
- Crustal Dynamics Data Information System (CDDIS)
- Global Hydrology Resource Center (GHRC)
- Goddard Earth Sciences Data and Information Center (GES_DISC)
- Level 1 and Atmosphere Archive and Distribution System (LAADS)
- Land, Atmosphere Near real-time Capability for EOS (LANCEMODIS)
- Land, Atmosphere Near real-time Capability for EOS (LANCEAMSR2)
- Langley Research Center (LARC)
- Langley Research Center (LARC_ASDC) Atmospheric Science Data Center
- Land Process DAAC - EOS Core System (LPDAAC_ECS)
- National Snow and Ice Data Center Version 0 (NSIDCV0)
- National Snow and Ice Data Center EOS Core System (NSIDC_ECS)
- Ocean Biology Processing Group (OBPG)
- Oak Ridge National Laboratory (ORNL)
- Physical Oceanography DAAC (PODAAC)
- Socioeconomic Data and Applications Center (SEDAC)
- U.S. Geological Survey Earth Resources Observation Systems (USGS_EROS)
- Australian Antarctic Data Centre (AU_AADC)
- European Space Agency (ESA)
- European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT)
- ISRO
- JAXA
- LM_FIRMS
