Introduction

• DoDAF Volume 2，
  1. defines DoD architectural viewpoints and models
  2. describes the DoDAF meta-model (DM2) as it is defined and specified in the DoD Meta Data Registry (MDR).
• The DoD requires architects to use DoDAF 2.0 for architecture descriptions because the DoDAF provides a standard format for exchanging architectural data.DoDAF concentrates on data ,architects must choose their methods and techniques to create, maintain, and present architectural data specified by the DoDAF meta-model.
• For convenience of architects and owners of architecture descriptions, we describe some conventional views into the DoDAF meta-model of architectural data.
• Owners of DoD core processes may determine the architectural data they require from architecture descriptions.Architects should review this guidance and comply with these requirements for specific models and views.

How this volume is organized

This volume contains information for architects and other technical professionals who develop, use, and maintain architecture.

• Section 1 the Introduction to this volume.
• Section 2 presents the DoDAF meta-model data groups; these data groups are the building blocks of architecture descriptions.
  • These data groups cover:
    • performers,
    • resource flows,
    • information and data,
    • rules,
    • capabilities,
    • services,
    • projects,
    • organizational structures,
    • measures,
    • locations,
    • pedigrees.
  • The discussions of each data group includes:
    • introductory information with an overview of the data group;
    • information about the types and relationships incorporated by the data group;
    • a DoDAF meta-model diagram that shows these types and relationships.
• Section 3 describes the viewpoints of the DoD architecture framework. Appropriate models are described for each of these viewpoints.
• Appendices to this volume provide extracts from the DoDAF Glossary.
  • Appendix B identifies and describes the core terms of the DoDAF model as these terms are used here.
  • Appendix C identifies and describes related terms, such as synonyms for core terms and names for patterns of DoDAF elements.
  • Appendix D discusses the sources that were consulted when constructing definitions for core DoDAF terms.
