No. DCAT deals with the initial problems of where dataset catalogs and datasets themselves are from and what they contain. Loosely speaking, it does for catalogs and datasets what Dublin Core did for publications: it provides a succinct vocabulary that providers can rely on for describing their datasets, and consumers can rely on for finding. DCAT has already been used as the basis for the schema.org "datasets" extension as a way to make discovery of datasets easier using popular search engines. Articulating the actual vocabularies used in published datasets is waaaay beyond the scope of DCAT, in part because DCAT is not restricted to datasets published as linked data. Some work including http://healthdata.tw.rpi.edu are looking at ways to communicate standard vocabularies used in published linked data... -- John S.
