This specificationis a component of version three (v3) of the Common Information Model(CIM) architecture. CIM v3 is a major revision of CIM. CIM v3 preserves the functionality of CIM v2, but it is not backwards compatible. The DMTF continuesto support the specifications that define CIM v2. However, new CIM v3 architectural features may not be added to CIM v2 specifications. This standard describes the Common Information Model (CIM) Meta model version 3, which is based on the Unified Modeling Language: Superstructure specification. CIM schemas represent object-oriented models that can be used to represent the resources of a managed system, including their attributes, behaviors,and relationships. The CIM Metamodelincludes expressions for common elements that must be clearly presented to management applications (for example, classes, properties, methods, and associations).
