Vous vous rappelez de l'initiative lcsh.info? Planet RDF signale la LoC a repris officiellement le principe.

"This is great news. This means that all items in the LoC subject heading have now a stable, dereferancable URI; the URI refers to a (SKOS) concept and is linked to broader and narrower terms. The implementation follows the LOD principles; the URI can be dereferenced in an HTML browser providing an RDFa annotated HTML page. To take an example, the subject heading for “Semantic Web” has the URI: http://id.loc.gov/authorities/sh2002000569#concept; dereferencing it leads to an XHTML+RDFa page. The RDF content can be accessed describing the concept in SKOS, providing a link to, eg, the concept of World Wide Web. This vocabulary gives a stable target to characterize the subject of various entities using, eg, the Dublin Core “subject” term. The site provides a search page and the whole dataset can also be downloaded in RDF/XML or n triples."
