In particular, current DCAT deployments that do not overlap with the DCAT 2 new features (e.g., data services, time and space properties qualified relations, packaging) don't need to change anything to remain in conformance with DCAT 2.ĭCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. DCAT 2 relaxes constraints and adds new classes and properties, but these changes do not break the definition of previous terms.Īny new implementation is expected to adopt DCAT 2, while the existing implementations do not need to upgrade to it, unless they want to use the new features. DCAT 2 maintains the DCAT namespace as its terms preserve backward compatibility with DCAT. Trademark and permissive document license rulesĭCAT 2 supersedes DCAT, but it does not make it obsolete.
