This page will capture the design of the Policy PEP Registration API and the resulting thePolicy Update Notifications on Dmaap notifications of policy updates. This work is related to the functional requirements from Control Loop subcommittee: Policy Update Notifications.

|---|---|---|---|---|---|---|---|---|

Option 1 - Don't implement the API at all
Use a well-known Dmaap topic for policy updates that any application can listen to. Look for the TOSCA Policy Type the component is interested in.
Option 2 - Implement the API to register a Dmaap topic for a specific Policy Type
ONAP components register a dmaap topic for Policy PAP to send simple notifications for a Policy Type that is either newly deployed, updated with a new version, or undeployed.

- policy-id was initial approach
- matchable filters was introduced later
- per team meeting:
- For Policy Update - need to add complexity of multiple PDP groups. How does the client know which group?
- Agree to just get the first cut done and address this later. Perhaps in G Release.
