Relationship between Indexes and Catalogs

Regarding the relationship between indexes and catalogs, we think that:

• Catalogs are referencing assets which are at the dataset levels (like [https](https://api.tems-stg.startinblox.com/objects/trial8/) for instance)
• Assets in the catalog are supposed to be protected by a contract, when a certain level of indexes can be public
• Indexes are referencing unitary resources existing in the datasets published as assets in the catalogs
• Indexes references unitary resources, which should themselves have a backlink to the datasets they are associated with

And there could still be missing pieces, but that is part of the job to identify this missing piece and solve it.
