In ANDSF, reference data is considered information that is needed to operate the policy engine, but not used for evaluating policies. For example, in the Reference Data tab in Cisco Policy Builder, are the forms used to define systems, clusters, and instances, and to set times and dates used for tariff switching. The policy engine needs to refer to this data only to process policies correctly. However, the data does not define the policy itself.
Policy Builder provides core plug-ins for customizing and optimizing your installation.
Configurations set at the system level are system-wide except as noted in the bullet items below.

Configurations set at the instance level apply to the instance only and override the same value set at the cluster or system level.

When you create a system from the example, the following configuration stubs appear at the cluster and instance level.
