Since this specification is based both on DCAT-AP and CPSV-AP, there was an inconsistency in the first model: the output of the registry service. The model tries to establish the relationship between a Public Service (i.e, the Registry Service that manages the base registry) and the main output under this context: the Base Registry (described as a dcat:Catalog).

According to the CPSV-AP: a cpsv:PublicService  -> cpsv:produces -> cv:Output (Output must have title and identifier, but we have them already in the description of dcat:Catalogs).

Since that Output produced by the public service is a dcat:Catalog. Should we use both types? It seems this is compatible. In this case, a base registry (or a registry of registries) would be both a dcat:Catalog and a cv:Output. The required properties to describe them, both in DCAT-AP and CPSV-AP, are also compatible.

Opinions?
