Announcement:  New Vocabulary Data Added to 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. **

Contact Us about ID:
As always, your feedback is important and welcomed. Though we are interested in 
all forms of constructive commentary on all topics related to ID, we're 
particularly interested in how the data available from ID.LOC.GOV is used. Your 
contributions directly inform service enhancements.

The addition of Names has resulted in considerable changes to the ID.LOC.GOV backend.  
Although we have endeavored to bring the service up with all pieces in place, please be 
patient as we work out any remaining "kinks".

You can send comments or report any problems to us via the ID feedback form or 
ID listserv (see the web site).

Background:
The Authorities and Vocabularies web service was first made available in May 
2009 and offered the Library of Congress Subject Headings (LCSH), the Library's 
initial entry into the Linked Data environment. In part by assigning each 
vocabulary and each data value within it a unique resource identifier (URI), 
the service provides a means for machines to semantically access, use, and 
harvest authority and vocabulary data that adheres to W3C recommendations, such 
as Simple Knowledge Organization System (SKOS), and the more detailed 
vocabulary MADS/RDF. In this way, the Authorities and Vocabularies web service 
also makes government data publicly and freely available in the spirit of the 
Open Government directive. Although the primary goal of the service is to 
enable machine access to Library of Congress data, a web interface serves human 
users searching and browsing the vocabularies.  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

The above code lists also contain links with appropriate LCSH and LC/NAF 
headings.  Additional vocabularies will be added in the future, including 
additional PREMIS controlled vocabularies.
