                 In DCAT 1 [[?VOCAB-DCAT-20140116]] the domain of <code>dcat:theme</code> was <code>dcat:Dataset</code>, which limited use of this property in other contexts. The domain has been relaxed in DCAT 2.

+                DCAT 3 maintains the same expectation as DCAT 2 for the use of the property <code>dcat:theme</code>, . DCAT 3 defines <code>dcat:theme</code> as an OWL object property and  drops its range to  make the formalization of the property more consistent with the expected use. In particular, the change intends to prevent that each entity used as object of <code>dcat:theme</code> is automatically inferred as <code>skos:Concept</code>. See issue <a href="https://github.com/w3c/dxwg/issues/1364">#1364</a>.
