![]() This section describes the status of thisĭocument at the time of its publication. The suggested prefix for the DCAT namespace is dcat Status of This Document 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. ![]() This document is also available in these non-normative formats:ĭCAT 3 supersedes DCAT 2, but it does not make it obsolete. ![]() Open with subject line … message topic … ( archives) Errata: Errata exists.
