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 recommendation defines the schema and provides examples for its use.
[edit] 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 Dataset (collection of data, published or curated by a single agent or identifiable community) example from the recommendation (Turtle):
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:keyword "responsabilidad"@es, "transparencia"@es, "pagos"@es ;
dcterms:creator ex:finance-employee-001 ;
dcterms:issued "2011-12-05"^^xsd:date ;
dcterms:modified "2011-12-15"^^xsd:date ;
dcat:contactPoint <http://dcat.example.org/transparency-office/contact> ;
dcterms:temporal [ a dcterms:PeriodOfTime ;
dcat:startDate "2011-07-01"^^xsd:date ;
dcat:endDate "2011-09-30"^^xsd:date ;
];
dcat:temporalResolution "P1D"^^xsd:duration ;
dcterms:spatial <http://sws.geonames.org/6695072/> ;
dcat:spatialResolutionInMeters "30.0"^^xsd:decimal ;
dcterms:publisher ex:finance-ministry ;
dcterms:language <http://id.loc.gov/vocabulary/iso639-1/en> ;
dcterms:accrualPeriodicity <http://purl.org/linked-data/sdmx/2009/code#freq-W> ;
dcat:distribution ex:dataset-001-csv ;
.
A Distriubtion (an accessible form of a dataset such as a downloadable file) example from the recommendation (in Turtle):
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 ; dcat:mediaType <http://www.iana.org/assignments/media-types/text/csv> ; dcat:byteSize "5120"^^xsd:nonNegativeInteger ; .
