DCAT

dcat is an RDF vocabulary for the exchange of data catalogs. Its primary purpose is the expression of government data catalogs, such as data.gov or data.gov.uk, in RDF.

The feasibility study puts four existing catalogs (data.gov, data.london.gov.uk, data.australia.gov.au and datasf.org) in RDF using dcat and provides a Linked Data interface and a SPARQL endpoint to access this data.
