Data Catalog Vocabulary (DCAT) is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web.
Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.
[1] The original DCAT vocabulary was developed at DERI, as an idea from Vassilios Peristeras and his master student Fadi Maali together also with Richard Cyganiak.
[2] A 2022 report reviews DCAT‑AP compliance on national data portals.
[5][6] An open-source licensed porting of the version DCAT-AP 2.0.1 compatible with NGSI-LD API standard is available in the DCAT-AP subject at Smart Data Models program.
