The VKC:Deployment and Run Time View shown in the architectural infrastructure diagram ( (Deployment and Run Time <<import>> Contract and Design <<import>> Semantic) comprises implementable specifications (which represent the key semantics); a configuration of enabling systems and contracts; and a run time view of systems interacting with each other to fulfill their contracts. Artifacts from this view are used in the ECCF to assess compliance. Each implementation of a service is expected to state its level of conformance with the implementation-independent specification of that service as expressed as RM/ODP enterprise/information/computation artifacts, such as Enterprise Metamodel - ITU-T Rec. X. 906 | ISO/IEC 19793 Use of UML for ODP system specifications. The closer the asserted level of conformance the higher the degree of semantic interoperability should be. Implementation viewpoint artifacts and functionalities are critical to empirically verifying that the expected level of interoperability has been achieved.

The diagram shows that Enabled behavior occurs between Establishing behavior and Terminating behavior, over the Period of liaison and the Period during which context exists. A contract may be instantiated multiple times with different liaisons.
