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
- Library of Congress Subject Headings (LCSH)
- Library of Congress Name Authority File (LCNAF)
- Library of Congress Classification—because LC Classification uses a different MARC format than LC Authorities, mapping LC Classification to MADS/RDF was more difficult than mapping LCSH or LCNAF. [2]
- Library of Congress Thesaurus for Graphic Materials
- Various MARC codes
- Various preservation vocabularies
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 (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]
