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]
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]
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]
The id.loc.gov site initially used a fairly lightweight Python program to serve linked data. [5]
Sanford Berman is a librarian. He is known for radicalism, promoting alternative viewpoints in librarianship, and acting as a proactive information conduit to other librarians around the world. His vehicles of influence include public speaking, voluminous correspondence, and unsolicited "care packages" delivered via the U.S. Postal Service. Will Manley, columnist for the American Library Association (ALA) publication, American Libraries, has praised Berman: "He makes you proud to be a librarian."

RDF Schema (Resource Description Framework Schema, variously abbreviated as RDFS, RDF(S), RDF-S, or RDF/S) is a set of classes with certain properties using the RDF extensible knowledge representation data model, providing basic elements for the description of ontologies. It uses various forms of RDF vocabularies, intended to structure RDF resources. RDF and RDFS can be saved in a triplestore, then one can extract some knowledge from them using a query language, like SPARQL.
The Library of Congress Subject Headings (LCSH) comprise a thesaurus of subject headings, maintained by the United States Library of Congress, for use in bibliographic records. LC Subject Headings are an integral part of bibliographic control, which is the function by which libraries collect, organize, and disseminate documents. It was first published in 1898, a year after the publication of Library of Congress Classification (1897). The last print edition was published in 2016. Access to the continuously revised vocabulary is now available via subscription and free services.
A finding aid, in the context of archival science and archival research, is an organization tool, a document containing detailed, indexed, and processed metadata and other information about a specific collection of records within an archive. Finding aids often consist of a documentary inventory and description of the materials, their source, and their structure. The finding aid for a fonds is usually compiled by the collection's entity of origin, provenance, or by an archivist during archival processing, and may be considered the archival science equivalent of a library catalog or a museum collection catalog. The finding aid serves the purpose of locating specific information within the collection. The finding aid can also help the archival repository manage their materials and resources.
Simple Knowledge Organization System (SKOS) is a W3C recommendation designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary. SKOS is part of the Semantic Web family of standards built upon RDF and RDFS, and its main objective is to enable easy publication and use of such vocabularies as linked data.
In information retrieval, an index term is a term that captures the essence of the topic of a document. Index terms make up a controlled vocabulary for use in bibliographic records. They are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. They are used as keywords to retrieve documents in an information system, for instance, a catalog or a search engine. A popular form of keywords on the web are tags, which are directly visible and can be assigned by non-experts. Index terms can consist of a word, phrase, or alphanumerical term. They are created by analyzing the document either manually with subject indexing or automatically with automatic indexing or more sophisticated methods of keyword extraction. Index terms can either come from a controlled vocabulary or be freely assigned.

Metadata Authority Description Schema (MADS) is an XML schema developed by the United States Library of Congress' Network Development and Standards Office that provides an authority element set to complement the Metadata Object Description Schema (MODS).
Polythematic Structured Subject Heading System is a bilingual Czech–English controlled vocabulary of subject headings developed and maintained by the National Technical Library in Prague. It was designed for describing and searching information resources according to their subject. PSH contains more than 13,900 terms, which cover the main fields of human knowledge.
The Schlagwortnormdatei or SWD is a controlled vocabulary index term system used primarily for subject indexing in library catalogs. The SWD is managed by the German National Library (DNB) in cooperation with various library networks. The inclusion of keywords in the SWD is defined by Regeln für die Schlagwortkatalogisierung (RSWK). Similar authority systems in other languages include the Library of Congress Subject Headings (LCSH) and the Répertoire d’autorité-matière encyclopédique et alphabétique unifié (RAMEAU). Since April 2012 the SWD is part of the Gemeinsame Normdatei (GND).
JSON-LD is a method of encoding linked data using JSON. One goal for JSON-LD was to require as little effort as possible from developers to transform their existing JSON to JSON-LD. JSON-LD allows data to be serialized in a way that is similar to traditional JSON. It was initially developed by the JSON for Linking Data Community Group before being transferred to the RDF Working Group for review, improvement, and standardization, and is currently maintained by the JSON-LD Working Group. JSON-LD is a World Wide Web Consortium Recommendation.
The Gemeinsame Normdatei or GND is an international authority file for the organisation of personal names, subject headings and corporate bodies from catalogues. It is used mainly for documentation in libraries and increasingly also by archives and museums. The GND is managed by the German National Library in cooperation with various regional library networks in German-speaking Europe and other partners. The GND falls under the Creative Commons Zero (CC0) licence.
Shriniwas Ganesh Sardesai (1907–1996) was an Indian nationalist from Maharashtra and one of the communist leaders in India. He is author of the book Progress and conservatism in ancient India.

BIBFRAME is a data model for bibliographic description. BIBFRAME was designed to replace the MARC standards, and to use linked data principles to make bibliographic data more useful both within and outside the library community.
Faceted Application of Subject Terminology (FAST) is a general use controlled vocabulary based on the Library of Congress Subject Headings (LCSH). FAST is developed as a part of WorldCat by OCLC, Inc., with the goal of making subject cataloging less costly and easier to implement in online contexts. FAST headings separate topical data from non-topical data, such as information about a document's form, chronological coverage, or geographical coverage.
The Nuovo soggettario is a subject indexing system managed and implemented by the National Central Library of Florence, that in Italy has the institutional task to curate and develop the subject indexing tools, as national book archive and as bibliographic production agency of the Italian National Bibliography. It can be used in libraries, archives, media libraries, documentation centers and other institutes of the cultural heritage to index resources of various nature on various supports
The National Agricultural Library Thesaurus (NALT) Concept Space is a controlled vocabulary of terms related to agricultural, biological, physical and social sciences. NALT is used by the National Agricultural Library (NAL) to annotate peer reviewed journal articles for NAL’s bibliographic citation database, AGRICOLA, PubAg, and Ag Data Commons. The Food Safety Research Information Office (FSRIO) and Agriculture Network Information Center (AgNIC) also use the NALT as the indexing vocabulary for their information systems. In addition, the NALT is used as an aid for locating information at the Agricultural Research Service (ARS) and the Economic Research Service (ERS) web sites and databases.
