A subsystem provides for availability checking on all necessary/desired objects prior to creating and coupling the objects. In one embodiment, the subsystem is knowledgeable of the objects it supports and each of the objects' related objects. The subsystem uses this information to determine the objects that are supported by both itself and a remote subsystem. The subsystem then uses this information to determine, prior to creating an instance of an object, whether the object and all of its related objects are supported by both the subsystem and the remote subsystem.
