Hello Experts,

We have a requirement to expose product char metadata on a TMF620 product offering price resource for the consumers of the API to perform charging domain function. As we do not have such metadata available on the standard spec we are exploring below options :

1) Uplift spec with TMF630 recommended Schema Based enhancements for Chars.

2) Uplift the API spec with bespoke enhancements to reduce the number of steps for the consumers.

To explain it further , in the example below the expectation is to provide metadata flag on each char to identify if the char is rate determining or not.   

"prodSpecCharValueUse": [
        {
          "name": "Char Name",
          "productSpecCharacteristicValue": [
            {
              "value": "Char Value"
            }

  "isChargable": "true",
          ]
   I would like to request guidance from the community on enhancement approach for such requirements. We also anticipate more such requirements in future from the consumers of the Catalog API for additional metadata.

Thanks in advance .
