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.
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.

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 in the table show the CMR collections and records missing that are missing the concept.

The UMM-Collection profile identifies 15 concepts which are required for inclusion in CMR metadata collections. Table 2 shows the overall percent completeness of required UMM-Collection concepts in the 8 Other metadata collections considered in this evaluation.

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 in the table show the CMR collections and records that are the concept.
