Data types a hash of a salt, and _msgSender(). is deterministic and thus requires hash collision protection. a hash of and name of the item. a hash of and name of the term.

The end-user facing explanation of what an item or term corresponds to is handled by the ServiceProviderData protobuf. The URI to find this protobuf is located in the ServiceProviderRegistry under the service provider. Definition of the descriptors is outside of scope for Videre, and is the job of the industry implementation.
