    As per the document TMF620B_Product_Catalog_API_Conformance_Profile_v4.1.0, for TMF620 conformance, only resources to be supported via TMF620 are
    Product Offering, POP and Product Specification.
    Also if we see POST operation, only mandatory attribute is Name. There are 1 or 2 conditional mandatory fields but basically just Name is mandatory. So for conformance, is support of only Name field be sufficient for all the 3 resources? Because for Get I see a big table with many mandatory fields.

    Hi Shubham
    It's a great discussion point, thanks for raising.
    For each API, the API designers are tasked with deciding what are the minimum sensible and feasible criteria for passing conformance.
    No-one will realistically claim that this minimum conformance will enable you to run a telco business.
    For this API, I take responsibility, and my explanation is as follows:
    • For entities, a product catalog is feasible even without the Catalog and Category entities - but I cannot survive without offerings and their building blocks - specs and prices. Also import and export are not absolutely essential.
    • For attributes, it is extremely difficult to determine which should be mandatory. I can in principle have product specs with no characteristics, for example. And not all POPs have actual price amounts - usage charges for example will not have price amounts.
    Thanks for your concern, I hope this clarifies things.
