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 26 CMR Metadata Collection (18 NASA and 8 Other) 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)

UMM-Collection Required Concepts in NASA Metadata Collections
The UMM-Collection profile identifies 15 concepts which are required for inclusion in CMR metadata collections. Table 1 shows the overall percent completeness of required UMM-Collection concepts in the 18 NASA metadata collections considered in this evaluation.

Specific Metadata Improvement Guidance
Of the 15 required concepts, 9 concepts are 100% complete in all CMR NASA collections, 5 concepts are > 90% complete in all CMR NASA collections, and 1 concept is > then 70% complete in all CMR NASA collections. Table 3 below provides detailed metadata improvement guidance for the 6 required concepts < 100% complete. The concept links connects to a Google Sheets filtered display that shows the CMR collections and records that are missing the concept. The filtered display column header is bold, and the first two columns in the table show which collection and records are the missing concept.

Specific Metadata Improvement Guidance
Of the 15 required concepts, 12 concepts are 100% complete in all CMR Other collections, 1 concepts is > 90% complete in all CMR Other collections, 1 concept is 60% complete in all CMR NASA collections, 1 concept is > 20% complete in all CMR Other collections. Table 4 below provides detailed metadata improvement guidance for the 3 required concepts < 100% complete. The concept links connects to a Google Sheets filtered display that shows the collections and records that are missing the concept. The column header for the concept is bold, and the first two columns in the table show which collection and records are the missing concept.
