NCMP has an inconsistency between the JSON supplied/received and what exists in the database. This is producing issues such as those related to CM Handle querying.

Breaks

Convention Impacts	Overall CPS Convention impact	Consistency between yang model and JSON	Cost
1	Change OpenApi to kebab-casing	No - This would involve changing what is in red above. So changes to cmhandle registration and JSON responses.	Java stays in camelCasing and changes the

json

JSON to kebab-casing. No breaking to Java to convention. JSON does not have convention. Inconsistency between our own APIs https://google.github.io/styleguide/jsoncstyleguide.xml?showone=Property_Name_Format#Property_Name_Format.

Would expect all endpoints to use kebab-casing: dataspace-name, schema-set.
Is what we do have now

Solved

Some endpoints effected

Version management needed

2

Change dmi-registry to camelCasing

No - Would involve internal changes. Only changes to CM Handle API.

IEEE Guidelines state yang identifiers should be in kebab casing https://1.ieee802.org/yang-guidelines/

Would expect all endpoints to use camel-casing: dataspaceName, schemaSet.

Foreseen Impacts

Change OpenApi to kebab-casing

We would change components.yaml to kebab-casing

components.yaml example

      properties:
        cmHandleState:

This would change generated Java class:

    return this;

      public CmHandleCompositeState cmHandleState(String cmHandleState) {

           return this;

Would involve new Liquibase changeset and updating dmi-registry everywhere.
