Notes:

  1. DMI plug-in: Ongoing discussions between Vishal team and Priyank team re. DMI-plugin

Current CPS version is v3.2.1. Priyank has made changes which will be available in v3.2.6 snapshot.

DMI plug-in codebase changes to allow AVC message to be populated for CM VES.

DMI plug-in code was committed on March 31 https://gerrit.onap.org/r/c/cps/ncmp-dmi-plugin/+/133948

Ongoing discussion about changes needed.


2. RAN-Sim: Changes for CM VES message generation.

CM VES event generated whenever there is a config change in CU and DU.
Code modified to align VES message to updated format (e.g, path and href attributes)


3. Vishal/Murali are following up with Dan Timoney re. https://gerrit.onap.org/r/c/ccsdk/sli/+/132541 for carryover code merge in CCSDK.


4. Priyank showed a demo of CPS APIs and how it applies to:
Recording available here: 20230404_son_call_cps_api_demo.mp4

Link for CPS Core API Swagger (local deployment)

http://localhost:8883/swagger-ui/index.html?configUrl=%2Fv3%2Fapi-docs%2Fswagger-config&urls.primaryName=cps-core#/

Plan is for NCMP to use these CPS APIs. But functions needed are not ready.

For SON use case London release, we need to use these CPS API for:

a. Initialization of CPS Core DB with yang model file and json file - this step is done manually for London release for SON use case, and can be done via DMI/NCMP if create MOI events are supported

b. Update (persist) config change in CPS Core DB based on CM VES msg - this is supposed to be done by NCMP in response to DMI-AVC message but not in place. For SON use case demo, this may be done manually.



SON use case can use the following as examples: 

son5g-dataspace ↔ dataspace
son-5g-usecase-model <->schema-set-name .. has the yang model
son5g-anchor ↔ cmHandle 

Use cpsData APIs

 - create node - node represents network root with atleast one Near-RT-RIC - using the json file as payload,

- get node to read all data for node

-PATCH to make update to only one attribute of MOI

-PUT to replace all attributes for an MOI
