Hi Keshav
1. I'm not quite sure what you mean by multiple levels of service catalog. Service catalog is basically a container for exposing service specifications. So you can have multiple catalogs, each catalog exposing a different subset of your service specifications. All of this is part of TMF633 service catalog API. TMF638 is the service inventory, where, as you say, the details of instantiated services and characteristic values are managed.
2. I don't have visibility on the availability on specific v5 APIs - it would be nice to believe that another tranche could be announced around DTW in June 2024 but I don't know if there are such plans.
