Hello, I have some comments about the dcat Vocabulary Reference document. I prefer discuss it here, before modifying the wiki. * Property 'Frequency' [1] needs to have a 'dct:Collection' as Domain. So, a Catalog must be a 'dct:Collection' as well. (I've modified this on the wiki). * Property 'Temporal Coverage' [2] could have literal values, typed as xsd:duration (based on the ISO 8601 standard)? Defined as 'PnYn MnDTnH nMnS'. * Property 'keyword/tag' [3] should not restrict its range to 'Literal'. Some tags might be added as a Resource. For instance, Faviki [4] uses semantic tags. Other example might use tags from a controlled vocabulary in SKOS. Best regards, Martin [1] http://www.w3.org/egov/wiki/Data_Catalog_Vocabulary/Vocabulary_Reference#Property:_frequency [2] http://www.w3.org/egov/wiki/Data_Catalog_Vocabulary/Vocabulary_Reference#Property:_temporal_coverage [3] http://www.w3.org/egov/wiki/Data_Catalog_Vocabulary/Vocabulary_Reference#Property:_keyword.2Ftag [4] http://www.w3.org/2001/sw/sweo/public/UseCases/Faviki/ -- Martín Álvarez Espinar http://www.fundacionctic.org
