External termsĭCAT incorporates terms from pre-existing vocabularies where stable terms with appropriate meanings could be found, such as foaf:homepage and dcterms:title. A summary of the changes from ] is provided in. This version of DCAT, DCAT 3, was developed by the Dataset Exchange Working Group, considering some of the more pressing use cases and requests among those left unaddressed in the previous standardization round. The original DCAT vocabulary was developed and hosted at the Digital Enterprise Research Institute (DERI), then refined by the eGov Interest Group, and finally standardized in 2014 ] by the Government Linked Data (GLD) Working Group.Ī second recommended revision of DCAT, DCAT 2 ], was developed by the Dataset Exchange Working Group in response to a new set of Use Cases and Requirements ] gathered from peoples' experience with the DCAT vocabulary from the time of the original version, and new applications that were not considered in the first version. Those believed to be a priority for a future release are in the milestone DCAT Future Priority Work.

Issues, requirements, and features that have been considered and discussed by the Data eXchange Working Group but have not been addressed due to lack of maturity or consensus are collected in GitHub. Implementation will be evidenced by showing use of the new properties/classes (or terms with equivalent meaning) in implementations of catalogs. The exit criteria for CR focused on v3 new features that replicate features that were included in application profiles of v2 as a way of remedying missing and necessary elements.

A full list of the significant changes (with links to the relevant GitHub issues) is described in.

This new version of the vocabulary updates and expands the original but preserves backward compatibility.

addition of a dcat:DatasetSeries class and properties for representing Dataset Series, see.

addition of properties for supporting versioning, e.g., dcat:version, dcat:previousVersion, dcat:hasCurrentVersion, see.

addition of spdx:checksum property and spdx:Checksum class to provide digest for DCAT distributions.

The main changes to the DCAT vocabulary have been: This revision extends the original DCAT standard in line with community practice while supporting diverse approaches to data description and dataset exchange. This document defines a major revision of the DCAT 2 vocabulary (]) in response to use cases, requirements and community experience which could not be considered during the previous vocabulary development. The suggested prefix for the DCAT namespace is dcat 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.Īggregated DCAT metadata can serve as a manifest file as part of the digital preservation process. This can increase the discoverability of datasets and data services. This document defines the schema and provides examples for its use.ĭCAT 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.

In particular, current DCAT 2 deployments that do not overlap with the DCAT 3 new features (e.g., versioning, dataset series and inverse properties) don't need to change anything to remain in conformance with DCAT 3.ĭCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web.

DCAT 3 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 3, while the existing implementations do not need to upgrade to it, unless they want to use the new features. DCAT 3 maintains the DCAT namespace as its terms preserve backward compatibility with DCAT 2. It extends DCAT 2 ] with terms and guidelines on inverse properties, versioning, and dataset series (see sections, and ), and by including terms for specifying the checksum of a distribution (see and ).ĭCAT 3 supersedes DCAT 2 ], but it does not make it obsolete. This document presents advancements in the discussion made on DCAT 3 within DXWG group. Data Catalog Vocabulary (DCAT) - Version 3
