Dear WG, Apologies for jumping in your discussion. but since your use case is about GeoDCAT-AP, I thought it was relevant to mention that DCAT-AP (and therefore also GeoDCAT-AP) supports the possibility of specifying the metadata standard / application profile), using exactly the solution proposed by Antoine - i.e.: my:CatalogRecord a dcat:CatalogRecord ; foaf:primaryTopic my:Dataset ; dct:conformsTo <metadata standard / application profile> .
