'''DCAT''' (Data Catalogue vocabulary) is a W3C Recommendation described as being an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. The [https://www.w3.org/TR/vocab-dcat-3/ recommendation] defines the schema and provides examples for its use.

== Identification ==

RDF-based documents containing key elements of the vocabulary might be probabilistically identified as DCAT, or at least, as a dataset using DCAT vocabulary elements.

A <code>Dataset</code> (collection of data, published or curated by a single agent or identifiable community) example from the recommendation ([Turtle]):

<pre>
ex:dataset-001
a dcat:Dataset ;
dcterms:title "Imaginary dataset"@en ;
dcterms:title "Conjunto de datos imaginario"@es ;
dcat:keyword "accountability"@en, "transparency"@en, "payments"@en ;

dcat:distribution ex:dataset-001-csv ;
.
</pre>

A <code>Distriubtion</code> (an accessible form of a dataset such as a downloadable file) example from the recommendation (in [Turtle]):

<pre>
ex:dataset-001-csv
a dcat:Distribution ;
dcat:downloadURL <http://dcat.example.org/files/001.csv> ;
dcterms:title "CSV distribution of imaginary dataset 001"@en ;
dcterms:title "distribución en CSV del conjunto de datos imaginario 001"@es ;
