Key features include the definition of codes in CSV or Genericode files, dynamic code lists via run-time binding, and multi-column code table support. Learn more...
The Conformance Targets Attribute Specification (CTAS) defines how NIEM XML documents indicate what kind of artifact they are through the use of a conformance targets attribute. Learn more...
The NIEM High-Level Version Architecture (HLVA) Specification identifies the processes, artifacts, and responsibilities required to produce new releases of the NIEM model. It also establishes a regular release cycle for predictable and manageable NIEM updates. Learn more...
