The Policy Framework participant receives messages through participant-intermediary common code, and handles them by invoking REST APIs towards policy-framework.
-For example, When a AutomationCompositionUpdate message is received by policy participant, it contains full ToscaServiceTemplate describing all components participating in an automation composition. When the automation composition element state changed from UNINITIALIZED to PASSIVE, the Policy-participant triggers the creation of policy-types and policies in Policy-Framework.
+For example, When a PARTICIPANT_UPDATE message is received by policy participant prompted by a PRIME, it contains the Automation Composition Element Definitions from the Tosca Service Template that was commissioned. An Automation Composition Instance can then be created from the commissioned definitions. When the automation composition instance element state changed from UNDEPLOYED to DEPLOYED, the Policy-participant receives a AUTOMATION_COMPOSITION_DEPLOY message, which triggers the creation of policy-types and policies in Policy-Framework.
-When the state changes from PASSIVE to UNINITIALIZED, Policy-Participant deletes the policies, policy-types by invoking REST APIs towards the policy-framework.
