Thanks, Kevin. This was obviously one heck of a project! Very impressive.

I looked at an entry in 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:

> 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).

> 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.
