TheLC Linked Data Service is an initiative of theLibrary of Congress that publishesauthority data aslinked data.[1]It is commonly referred to by its URI: id.loc.gov.[2]
The first offering of the LC Linked Data Service was theLibrary of Congress Subject Headings (LCSH) dataset, which was released in April 2009.[3]
The Library of Congress offers users the opportunity to create their own datasets with library application profiles (APIs).Create your own datasets
The service presents data inMADS/RDF andSKOS where appropriate, but also uses its own ontology to describe classification resources and relationships more accurately.[2] All records are available individually viacontent negotiation asXHTML/RDFa,RDF/XML,N-Triples, andJSON.[4]
Each vocabulary is also available to download in its entirety. Id.loc.gov does not currently provide aSPARQL endpoint.[5][6]
All of LCSH are crosslinked withRAMEAU [d] (Répertoire d’autorité-matière encyclopédique et alphabétique unifié), an authority file from theBibliothèque nationale de France.[4]
The id.loc.gov site initially used a fairly lightweightPython program to serve linked data.[5]
