M&S Services at the Crossroads of Service Oriented Architecture and the DoD Architectural Framework Bernard P. Zeigler, Ph.D., Arizona Center for Integrative Modeling and Simulation and Joint Interoperability Test Command Fort Huachuca, AZ

Influences on M&S COI Tasks M&S Body of Knowledge M&S Theory and Framework DoD Architectural Framework MetaData Mediation Services

DoD Architectural Framework (DoDAF) DoD mandate requires that the DoD Architectural Framework (DoDAF) be adopted to express high level system and operational requirements and architectures. DoDAF is the basis for the integrated architectures mandated in DOD Instruction and provides broad levels of specification related to operational, system, and technical views. Operational views capture the requirements of the architecture being evaluated System views provide its technical attributes

Implications for GIG/SOA and M&S COI The development of the Global Information Grid (GIG) and its service oriented architecture (SOA) –The concerns of the M&S COI must eventually be expressed within the appropriate DoDAF views. –The services offered by the M&S COI must be architected within the DoDAF operational views Obstacles: The DoDAF essential approach is that of systems orientation rather than service orientation The DoDAF expresses interest in development of executable architectures but does not explicitly elucidate M&S support

Conclusions Correlating DoDAF with SOA Life Cycle Development process and M&S is not straightforward DoDAF needs elaboration with service oriented views To support M&S needs –elaboration of downstream life cycle –integration of verification testing along cycle –integration of evaluation along cycle (connection with NR-KPP)
