1

VES Event is received via Strimzi/DMaap Kafka on DMI.

Yes. This is agreed.

2

Changes in CM data will result in CPS-Core sending a CPS Data AVC irrespective the origin of the change.

See #4 in the Bigger Picture below.
This could later be model controlled to be more granular.

Agreed.

1

CM VES Message format schema.

Who will own it ?

In order to process the message DMI plugin / NCMP should be aware of the schema of the incoming message it is going to be consume.

VES format primary reference is here: [INT-2180] Define CM VES message aligned with 3GPP/O-RAN O1 - ONAP JIRA

2

Topic from where we will receive the CM VES Message.

Existing channel or channel owned by NCMP/DMI

Vishal Varvate to provide the topic details.

Priyank Maheshwari ,please use below topic

unauthenticated.SEC_3GPP_PROVISIONING_OUTPUT

3

Mapping of the relevant information from the CM VES Message

CmHandle
Xpath
Operation that happened

Only fields that seem to suggest to have these info. are.

moiChanges.operation
moiChanges.value
moiChanges.path ??

Related work in ONAP suggests this possible alternative schema:

https://wiki.o-ran-sc.org/display/SIM/Network+Slicing+Use+Case#NetworkSlicingUseCase-ExampleVESPMstndDefined

So wanted to confirm if measurements.measurement-type-instance-reference is xpath?

The fields which are of importance are :

event.sourceId ( we can extract cmHandle details from the sourceId )

moiChanges.operation

moiChanges.path

Yang Resource : cps- ran-schema-model ( tree form : network to be used. ( trimmed down version just like cps-ran-schema-model _tree.txt ) existing ran-schema will be used.
We need to have a defined channel/topic where the VES messages are present , and NCMP should be able to listen , interpret/process and call the relevant CPS-Core APIs in order to publish the changes in the CPS DB.
