The W3C Dataset Exchange Working Group has published Data Catalog Vocabulary (DCAT) – Version 2 as a W3C Recommendation. DCAT defines an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. The specification defines the schema and provides examples for its use. Version 2 extends the original DCAT standard in line with community practice while supporting diverse approaches to data description and dataset exchange.
