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