Core architecture data model

[2] The CADM is essentially a common database schema, defined within the US Department of Defense Architecture Framework DoDAF.

The use of the underlying CADM faithfully relates common objects across multiple views.

Conformance with the CADM ensures the use of common architecture data elements (or types).

This DoDAF version restructured the C4ISR Framework v2.0 to offer guidance, product descriptions, and supplementary information in two volumes and a desk book.

CADM can continue to be used in support of architectures created in previous versions of DoDAF.

It contains a set of “nouns,” “verbs,” and “adjectives” that, together with the “grammar,” allow one to create “sentences” about architecture artifacts that are consistent with the DoDAF.

Regardless of how one chooses to represent the architecture description, the underlying data (CADM) remains consistent, providing a common foundation to which analysis requirements are mapped.

[3] The counterpart to CADM within NASA is the NASA Exploration Information Ontology Model (NeXIOM), which is designed to capture and expressively describe the engineering and programmatic data that drives exploration program decisions.

NeXIOM is intended to be a repository that can be accessed by various simulation tools and models that need to exchange information and data.
