4. The Purpose of DoDAF: 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)

5. What is the DM2
Architectural descriptions are models of aspect(s) of the enterprise
Common model types are described in DoDAF: AV-1 through DIV-3
Other models are called “fit-for-purpose”
The DM2 is a model of those models, hence “meta”
The DM2 has several levels, each of which is important to a particular viewer of Departmental processes.

6. DoDAF Meta Model (DM2) Purposes
Establish the constrained vocabulary for description and discourse about DoDAF models (formerly “products”) and their usage in the 6 core processes
Specify a way 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)
Increase the utility and effectiveness of architectural descriptions via a mathematical data model so they can be:
Integrated and cross-walked
Analyzed, evaluated, and assessed quantitatively
The overall goals of the DM2 are to, 1) provide a basis for semantic precision in architectural descriptions to support heterogeneous architectural description integration and analysis in support of core process decision making, and 2) provide semantics foris information sharing across the DoD Enterprise Architecture (EA) Community of Interest (COI).

7. The DM2 Has Three Levels
A conceptual level or Conceptual Data Model (CDM) defines concepts and relationships between them
business language of the enterprise
normative across the six core processes
A logical level or Logical Data Model (LDM) formalizes the relationships in the CDM mathematically
A physical level or Physical Exchange Specification (PES)
adds required NCDS metadata for security and pedigree to the LDM
is generated from the LDM 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.

8. The DM2 has Model, Definition, and Description Pieces

9. 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.
