Basic DCAT supports the indication of dataset semantics through

• dcat:keyword - which has a literal value
• dcat:theme - which uses a skos:Concept from a controlled vocabulary
• dct:subject - intended to be used with a link to a value in a controlled vocabulary

The semantics of these properties are quite weak. Specializations or additional predicates might be used to support more explicit semantic descriptions of datasets, to support cross-domain research data discovery and initial assessment.
