Hello Jeni and Paul,

Thanks for your feedback regarding representing provenance in DCAT.

DCAT properties were based on a survey of existing government catalogs. At the time of the survey, catalogs didn't include provenance description.
I totally agree that including a provenance description is very valuable. However, in the favour of keeping DCAT minimal and focused, I suggest that 
instead of adding properties from PROV to the DCAT spec, a link to PROV-O ontology is added as currently implemented in the draft (Catalog record section):
https://dvcs.w3.org/hg/gld/raw-file/default/dcat/index.html#Class:_Catalog_record

I hope that is sufficient.
