Dear all,

I'd like to announce the release an *experimental* service [1] that provides the RAMEAU subject headings as open linked data.
Rameau [2] is the main subject vocabulary used at the French national library (BnF) and many other French institutions. This site, a result of the TELplus project, and a collaboration between the Vrije Universiteit Amsterdam and BnF, aims at encouraging experimentation with Rameau on the web of data.

RAMEAU Concepts are described here according to the SKOS model [3] to represent knowledge organization systems in RDF. Each concept comes with labelling information but also semantic relations to other concepts and various kind of notes. Concepts have URIs of the form http://stitch.cs.vu.nl/vocabularies/rameau/ark:/12148/cb11932889r.

RDF/HTML content negociation:
This service follows the Best Practice Recipes for Publishing RDF Vocabularies [4]. Depending a web agent's preference, it can serve RDF/XML or HTML descriptions of concepts--note that the HTML pages contain RDFa markup.

Semantic alignment to LCSH:
Many concepts served here are semantically connected to the Library of Congress Subject Headings linked data (soon to be) available at http://id.loc.gov. This is done using 60,000 manual mappings provided by the MACS project [5]. Thanks to them, you will be able to "follow your nose" between one vocabulary and the other.

The RAMEAU version served here contains 157,280 concepts, of which 96,825 correspond to common nouns and 51,646 to geographic names.

Comments are highly welcome, either by personal mail, or via the LOD and SWD mailing lists. This is an experimental prototype, and any feedback--even positive!--could be useful to implement a more robust version of it in the future!

For more information, please visit [1] or contact aisaac at few.vu.nl. 

Thanks a lot for your attention,
