Core Model
The Core Model captures notions that are applicable to all
areas of management. The core model is a set of classes,
associations, properties and methods that provide a basic vocabulary
for describing managed systems. The Core Model represents
a starting point for determining how to extend the Common
schema.
Common Models
The Common Models are information models that capture notions
that are common to particular management areas, but independent
of any particular technology or implementation. Examples of
common models include systems, applications, networks and
devices. The classes, associations, properties and methods
in the Common Models are intended to provide a view of the
area that is detailed enough to use as a basis for program
design and, in some cases, implementation.
Extension Schema
Extension schemas represent technology-specific extensions
of the common models. These schemas are specific to environments,
such as operating systems. It is expected that the Common
Models will evolve as a result of the promotion of objects
and properties defined in the Extension Schemas.
