The IWbemPropertyProvider interface is a callback interface implemented only by dynamic property providers. These providers must map their implementations to individual properties in a CIM class instance, usually by specifying qualifiers in a MOF file. CIMOM is the only client of this interface, and it calls the methods whenever the properties are required by a client application. At that time, the property provider looks up the corresponding property value from its own data sources, and returns it to CIMOM.
