Thanks, Kevin. This was obviously one heck of a project! Very impressive.
I looked at an entry in id.loc.gov and in VIAF and couldn't
immediately see a connecting URI (browsing through the RDF/XML) -- is
there one, or are there plans to create those links between the two
vocabularies? Here are the records I was looking at:

Quoting "Ford, Kevin" <[email protected]>:
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.
