I'm not the official authority on this topic (that would be Mike Daconta), but I will take a confident and informed shot at it anyway as Mike likes me to do (you've already stated much of this in your response below): Vocabularies/models such as GJXDM and the NIEM (which are merging to become NIEM 1.0, as you know) can be associated with all 3 of the FEA DRM's primary standardization areas: - Data Description: Each element/attribute/data type could be mapped to entity/attribute-based representations, such as logical data models; - Data Exchange: These vocabularies define on-the-wire messages, and can therefore be mapped to Exchange Packages; - Data Context: The entities that comprise the Exchange Packages can be categorized according to taxonomies, which may be FEA reference models, or other taxonomies that are agency-specific, community of interest (COI)-specific, or cross-COI. These associations can aid in multiple areas, the most pertinent one here being harmonization (mapping 2 or more vocabularies with each other through the common reference model). That is one of the multiple values of the DRM.
