DDMS defines discovery metadata elements for resources posted to community and organizational shared spaces.
The elements in the DDMS are designed to be platform, language, and implementation-independent, and the specification is described with an XML Schema.
This is the first version to recast DDMS within the bounds of the Intelligence Community's Trusted Data Format specification.
DDMS 5.0 requires TDF V2 and associated IC specifications (ISM V10, NTK V8, VIRT V1).
The Core Layer is composed of five sets of element categories, each with a specific functional focus for describing a data asset: Major version releases contain changes which break backwards compatibility with earlier versions.
