3. DoDAF 2 Goals Support DoD’s core processes:
Capabilities Integration and Development (JCIDS)
Planning, Programming, Budgeting, and Execution (PPBE)
Acquisition System (DAS)
Systems Engineering (SE)
Operations Planning
Capabilities Portfolio Management (CPM)
Establish guidance for architecture content as a function of purpose – “fit for purpose”
Increase utility and effectiveness of architectures via a rigorous data model – the DoDAF Meta Model (DM2) -- so the architectures can be integrated, analyzed, and evaluated to mathematical precision.

4. DoDAF Meta Model (DM2) Purposes
The constrained vocabulary for description and discourse about DoDAF models (formerly “products”) and their usage in the 6 core processes
Specification for federated EA data exchange between:
architecture development and analysis tools
architecture databases
other authoritative data sources
Support discovery and understandability of EA data:
Discovery of EA data using DM2 categories of information
Understandability of EA data using DM2’s precise semantics augmented with linguistic traceability (aliases)

5. What is the DM2 The DM2 has three levels, .
A conceptual level or Conceptual Data Model (CDM) defines the high-level data constructs from which Architectural Descriptions are created in non-technical terms, so that executives and managers at all levels can understand the data basis of Architectural Description.
A Logical Data Model (LDM) adds technical information, such as attributes to the CDM and, when necessary, clarifies relationships into an unambiguous usage definition.
A Physical Exchange Specification (PES) consists of the LDM with general data types specified and implementation attributes (e.g., source, date) added, and then generated as a set of XSD’s, one schema per DoDAF-described Model.
The DM2 has several levels, each of which is important to a particular viewer of Departmental processes.

6. What is the DM2
The DM2 consists of the following data items:

7. Where is the DM2
DM2 Collaboration Site. working copy of the DM2 is maintained on a TWG collaboration site, along with all reference and research materials and the current action item tracker.
DKO DoD CIO EA&S Site
DoD Meta Data Registry (MDR) ARCH namespace. ARCH namespace has CDM (eap and xmi), LDM (eap, xmi, and xls), and PES (xsd’s). Can be accessed via DoD EA COI.
