Policy API
DESCRIPTION
The Policy subsystem of ONAP maintains, distributes, and operates on the set of rules that underlie ONAP’s control, orchestration, and management functions. Policy provides a centralized environment for the creation and management of easily-updatable conditional rules. It enables users to validate policies and rules, identify and resolve overlaps and conflicts, and derive additional policies where needed. The following operations are supported by the policy API:
Create policies on the PAP
Update policies on the PAP
Delete policies on the PAP or PDP
Push policies from the PAP to the PDP
List policies on the PDP
Get config data of policies on the PDP
Create Dictionary Items
Update Dictionary Items
Retrieve Dictionary Items
Import Micro Services Models
Retrieve Metrics for policy counts from PDP and PAP

ADDITIONAL EXAMPLES
Deleting a Policy from PAP
// Deleting from PAP will remove the policy from the PolicyEntity & PolicyVersion tables (UI-Editor tab).
// This means that the policy is no longer be available in Policy System.
// PayLoad:

"policyComponent": "PAP", //component name
"deleteCondition": "ALL" //versions (ALL or CURRENT)
}
Deleting a Policy from PDP
// Deleting from PDP will delete the policy from the PDP Group. The policy is still available in Policy System.
// When the policy is needed again, the policy should be pushed to the PDP.
// PayLoad:
