New Vocabulary Data Added to LC Authorities and Vocabularies Service

A logo of the Unites States Library of Congres...Image via WikipediaLC has announced that new vocabulary data has been added to the LC Authorities and Vocabularies Service.
The Library of Congress is pleased to make available additional vocabularies from its Authorities and Vocabularies web service (ID.LOC.GOV), which provides access to Library of Congress standards and vocabularies as Linked Data. The new dataset is:
  • Library of Congress Name Authority File (LC/NAF)
In addition, the service has been enhanced to provide separate access to the following datasets which have been a part of the LCSH dataset access:
  • Library of Congress Genre/Form Terms
  • Library of Congress Children's Headings
The LC/NAF data are published in RDF using the MADS/RDF and SKOS/RDF vocabularies, as are the other datasets. Individual concepts are accessible at the ID.LOC.GOV web service via a web browser interface or programmatically via content-negotiation. The vocabulary data are available for bulk download in MADS and SKOS RDF (the Name file and main LCSH file will be available by Friday, August 12).

Please explore it for yourself at http://id.loc.gov.

The new datasets join the term and code lists already available through the service:
  • Library of Congress Subject Headings (LCSH)
  • Thesaurus of Graphic Materials
  • MARC Code List for Relators
  • MARC Code List for Countries (which reference their equivalent ISO 3166 codes)
  • MARC Code List for Geographic Areas
  • MARC Code List for Languages (which have been cross referenced with ISO 639-1, 639-2, and 639-5, where appropriate)
  • PREMIS vocabularies for Cryptographic Hash Functions, Preservation Events, and Preservation Level Roles

Unshelved

Today's Unshelved has cataloging references.

In other comic news, Rachael Rising by Terry Moore is off to a great start. Very creepy.

Linking to LCSH and LCC

Linking to LCSH and LCC: Controlled Subject Headings and Classification Systems through the Web Barbara Tillett, Libby Dechman, and Loche McLean will be presented on August 16, 2011, at the World Library and Information Congress : 77th IFLA General Conference and Assembly in San Juan.
The Library of Congress is making its controlled vocabularies and classification system freely accessible on the Web. This presentation describes our services related to two of those controlled vocabularies and classification schemes: the Library of Congress Subject Headings and Library of Congress Classification. It also describes the work to link various language versions of LCSH together.

The initial structure for this service uses SKOS, Simple Knowledge Organization System, which “Provides a model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, folksonomies, and other similar types of controlled vocabulary.

Additionally we are exploring RDF XML as another structure to use for presenting this data. The service can be found at http://id.loc.gov and the LCSH/SKOS is at http://id.loc.gov/authorities.
Thanks to Gary Price for bringing this to my attention.
