-Policy Management
-=================
+************
+Policy Types
+************
Policies are based on types. The set of available policy types is determined by the set of policy types supported by
Near |nbh| RT |nbsp| RICs. At startup, the Policy Agent queries all Near |nbh| RT |nbsp| RICs for their supported types
to date. Policy types cannot be created, updated or deleted using this interface since this must be done via the
Near |nbh| RT |nbsp| RICs.
-Policies can be queried, created, updated, and deleted. A policy is always created in a specific
-Near |nbh| RT |nbsp| RIC.
-
-When a policy is created, the Policy Agent stores information about it in its internal repository. At regular intervals,
-it then checks with all Near |nbh| RT |nbsp| RICs that this repository is synchronized. If, for some reason, there is an
-inconsistency, the Policy Agent will start a synchronization job and try to reflect the status of the
-Near |nbh| RT |nbsp| RIC. If this fails, the Policy Agent will delete all policies for the specific
-Near |nbh| RT |nbsp| RIC in the internal repository and set its state to *UNKNOWN*. This means that no interaction with
-the Near |nbh| RT |nbsp| RIC is possible until the Policy Agent has been able to contact it again and re-synchronize its
-state in the repository.
