The Core Model provides the underlying, general assumptions of the managed environment--for example, that specific, requested data must be contained in a location and distributed to requesting applications or users. These assumptions are conveyed as a set of classes and associations that conceptually form the basis of the managed environment. The Core Model is meant to introduce uniformity across schemas intended to represent specific aspects of the managed environment.
For applications developers, the Core Model provides a set of classes, associations, and properties that can be used as a starting point to describe managed systems and determine how to extend the Common Model. The Core Model establishes a conceptual framework for modeling the rest of the managed environment.
The Core Model provides classes and associations to extend specific information about systems, applications, networks, devices, and other network features through the Common Model and extensions.
