Most CIM objects are stored in the Implementation namespace. If you know the URL and the Implementation namespace in advance, you can enumerate objects directly by connecting to that namespace.

The Interop namespace contains a few CIM objects, particularly instances of

CIM_RegisteredProfile

. One of these instances exists for each CIM profile that is fully implemented on the managed server.

CIM_RegisteredProfile

acts as a repository of information that can be used to identify and access objects in the Implementation namespace. For each registered CIM profile, the CIM server has an association that you can follow to move from the Interop namespace to the Implementation namespace.

Some profiles in the VMware implementation are only partially implemented. The implementation does not include all the mandatory properties and methods for those profiles. The Interop namespace does not contain instances of

CIM_RegisteredProfile

for profiles that are only partially implemented. To access unregistered profiles, you must know the Implementation namespace.
