Namespace URI

The namespace URI for DCAT is http://www.w3.org/ns/dcat#.

Alternative serialisations

The vocabulary is published both in human- and machine-readable forms. A GET request made to the canonical namespace URI will cause HTTP Content Negotiation to occur, which means that the most appropriate variant will be served according to your request. However, if you explicitly wish to retrieve a particular serialisation, you can also do so using the following URLs:

dcat.html
HTML (this document)
dcat.ttl
RDF (Turtle)
dcat.rdf
RDF/XML
dcat.jsonld
RDF (JSON-LD)

In addition, the RDF for externally defined terms where DCAT has provided additional documentation or usage notes can be found at dcat-external.ttl and alternatively dcat-external.rdf (XML/RDF) or dcat-external.jsonld (JSON-LD)

Older Versions of Ontology files

The ontology for the 2014 version of DCAT can be seen in Turtle or RDF/XML. Version 2 aims to be backwardly compatible with this earlier version.
