This Data Encoding Specification (DES) defines the XML elements and attributes; associated structures and relationships; mandatory and cardinality requirements; and permissible values for representing NTK metadata associated with an information resource or part of an information resource using XML. NTK.XML can be incorporated into other Data Encoding Specifications.
NTK metadata facilitates automated systems making a “need-to-know” (NTK) access determination about an information resource. These metadata are used to represent the system-specific properties assigned to an information resource that will be used, in conjunction with information about the user, and possibly other information, to determine the user’s access to the data. A single information resource may include multiple occurrences of these metadata in order to specify NTK information according to multiple, different access systems.
Compliance with this specification is measured against all aspects of the technical and documentary artifacts contained within the specification release package.
This specification is maintained by the IC Chief Information Officer via the Data Coordination Activity (DCA) and Common Metadata Standards Tiger Team (CMSTT).
