Re: issue-202: asserting the dataset's metadata conforms to certain standards

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> .
