Study

• During registration of a cmHandle the optional parameter dataProducerIdentifier can be specified
• Can be registered with no dataProducerIdentifier and be updated later (once)
• No validation on the entered string

How:

• Modify docs/openapi/components.yaml#RestInputCmHandle to include dataProducerIdentifier
• Modify org/onap/cps/ncmp/api/models/NcmpServiceCmHandle.java to include dataProducerIdentifier
• Modify cps-ncmp-service/src/main/java/org/onap/cps/ncmp/api/impl/yangmodels/YangModelCmHandle.java to include dataProducerIdentifier
• Logic in cps-ncmp-service/src/main/java/org/onap/cps/ncmp/api/impl/NetworkCmProxyDataServicePropertyHandler.java to support updating dataProducerIdentifier and logging errors
• Modify DMI Registry Model to include dataProducerIdentifier

A/C:

1. The DB view will show the  dataProducerIdentifier  
2. get CM Handle (Rest endpoint) wil include the dataProducerIdentifier
3. Swagger UI Documentation contains explanation about dataProducerIdentifier  
4. Update attempt of non-blank dataProducerIdentifier will be ignored but visible as warning in logs (other properties might be updated)
5. Demo above
