Abstract:

To unify the architecture data modeling in the joint demonstration pattern, joint demonstration meta-model (JDM2) is proposed based on international defense enterprise architecture specification(IDEAS). Business object reference ontology(BORO), IDEAS and department of defense meta-model(DM2)are introduced, the causes that the DM2 do not apply to describe joint demonstration content and the merits of DM2’s three layers from the perspective of design mechanism are analyzed.The merits of DM2 are made up of conceptual data model(CDM), logical data model(LDM)and physical exchange schema(PES). Finally, the conceptual data model and the logical data model in JDM2 are presented based on joint demonstration space, ontology theory, ideas of DM2 design and IDEAS. The JDM2 has been proved feasible with an example.
