The SV-4 Metamodel is similar to the process metamodel used for OV-5 and OV-6a. In this Metamodel, participants can be assigned by any of the items modeled in the SV-1 model. This assignment can be done at the general level (Application, Artifact, Resource Architecture) or at a more accurate level within the context of an architecture (Application Host, Physical Asset, Architecture Use).

Note: Since the organizational part defined in the OV-4 model is included in system models, both org-units (general level) and Human Assets (contextual level) can be assigned to participations.
