To facilitate discovery of data assets, users and applications will provide metadata for all data posted to the shared data spaces, in accordance with the NATO Core Metadata Specification (NCMS) which is standardized through STANAG 5636. The NCMS provides a common set of structured attributes that support discovery and effective use of data assets using search tools. Information producers will determine the desired level of discovery for a data asset. The NCMS incorporates best practices in metadata development from DCMI, International Standards Organization, other military and civilian metadata standards. Security-related metadata will be provided for each data asset in accordance with STANAG 4774 to enable controlled access to assets where binding metadata to data is specified in STANAG 4778.
