The LC Linked Data Service is an initiative of the Library of Congress that publishes authority data as linked data.[1] It is commonly referred to by its URI: id.loc.gov.[2]

The first offering of the LC Linked Data Service was the Library of Congress Subject Headings (LCSH) dataset, which was released in April 2009.[3]

Datasets

Formats

The service presents data in MADS/RDF and SKOS where appropriate, but also uses its own ontology to describe classification resources and relationships more accurately.[2] All records are available individually via content negotiation as XHTML/RDFa, RDF/XML, N-Triples, and JSON.[4]

Each vocabulary is also available to download in its entirety. Id.loc.gov does not currently provide a SPARQL endpoint.[5][6]

Uses

All of LCSH are crosslinked with RAMEAU (d) (Répertoire d’autorité-matière encyclopédique et alphabétique unifié), an authority file from the Bibliothèque nationale de France.[4]

Technical aspects

The id.loc.gov site initially used a fairly lightweight Python program to serve linked data.[5]
