Policy-Driven Routing Management Using CIM - Computer Network Security - page 261

BGPRouteMapsInRoutingPolicy defines the BGPRouteMaps that are used by a
particular RoutingRule object. BGPRoutingPolicy is a specialization of the
Dependency association, and defines the relationship between a BGPService and the
RoutingRule that control it. FilteredBGPAttributes is a specialization of the
Component aggregation, which is used to define the set of BGP Attributes that are
used by a particular RoutingAction .

3 Mapping CIM to XML

The CIM schema is independent of any implementation. However, for an information
model to be useful, it has to be mapped into some implementation. Thus, as Figure 2
shows, CIM can be mapped to (or represented as) several structured specifications.
According to our approach, the CIM schema can be mapped to structured
specifications such as XML, which can then be used to take advantage of XML
technology and related tools. Other specifications such as MOF/CIM (Managed
