The DM2 defines architectural data elements and enables the integration and federation of Architectural Descriptions. It establishes a basis for semantic (i.e., understanding) consistency within and across Architectural Descriptions. In this manner, the DM2 supports the exchange and reuse of architectural information among JCAs, Components, and Federal and Coalition partners, thus facilitating the understanding and implementation of interoperability of processes and systems. As the DM2 matures to meet the ongoing data requirements of process owners, decision makers, architects, and new technologies, it will to a resource that more completely supports the requirements for architectural data, published in a consistently understandable way, and will enable greater ease for discovering, sharing, and reusing architectural data across organizational boundaries.
To facilitate the use of information at the data layer, the DoDAF describes a set of models for visualizing data through graphic, tabular, or textual means. These views relate to stakeholder requirements for producing an Architectural Description.
DM2's Three Levels
Each of these is important to a particular viewer of Departmental processes.
The DM2 consists of the following data items:
The LDM and PES can be obtained from the DoD Meta Data Registry (MDR) ARCH namespace. The ARCH namespace serves the DoD EA Community of Interest (COI). The DoD MDR is the authoritative source for all DoD metadata. This DoDAF site contains CDM as well as LDM, PES, and ontology documentation.
