The   Dataset Exchange Working Group   published   Data Catalog Vocabulary (DCAT) - Version 3   as a W3C Recommendation. DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use.  DCAT enables a publisher to describe datasets and data services in a catalog using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs. This can increase the discoverability of datasets and data services. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process.

  Today the   Dataset Exchange Working Group   published   Data Catalog Vocabulary (DCAT) - Version 3   as a W3C Proposed Recommendation. DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use.  DCAT enables a publisher to describe datasets and data services in a catalog using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs. This can increase the discoverability of datasets and data services. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process.

  The   Dataset Exchange Working Group   invites implementations of the   Data Catalog Vocabulary (DCAT) - Version 3   Candidate Recommendation Snapshot. DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines a major revision of the DCAT 2 vocabulary ([ VOCAB-DCAT-2 ]) in response to use cases, requirements and community experience which could not be considered during the previous vocabulary development. This revision extends the DCAT standard in line with community practice while supporting diverse approaches to data description and dataset exchange. Comments are welcome via the  GitHub issues  by  15 February 2024 .

19 November 2019 The  Dataset Exchange Working Group  has published a Proposed Recommendation of  Data Catalog Vocabulary (DCAT) – Version 2 . DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. DCAT enables a publisher to describe datasets and data services in a catalog using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs. This can increase the discoverability of datasets and data services. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process. Comments are welcome through  7 January 2020.

3 October 2019 The  Dataset Exchange Working Group  has published a Candidate Recommendation of  Data Catalog Vocabulary (DCAT) – Version 2 . DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. DCAT enables a publisher to describe datasets and data services in a catalog using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs. This can increase the discoverability of datasets and data services. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process.

9 May 2018 The  Dataset Exchange Working Group  has published a First Public Working Draft of  Data Catalog Vocabulary (DCAT) – revised edition . DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. By using DCAT to describe datasets in data catalogs, publishers are using a standard model and vocabulary that facilitates the consumption and aggregation of metadata from multiple catalogs, and in doing so can increase the discoverability of datasets. It also makes it possible to have a decentralized approach to publishing data catalogs and makes federated search for datasets across catalogs in multiple sites possible using the same query mechanism and structure. Aggregated DCAT metadata can serve as a manifest file as part of the digital preservation process.
