[open-bibliography] New BNB sample data available

Fri Feb 4 11:15:31 UTC 2011

Antoine, Jeff,

Yes, we're hoping to use LCSH in MADS/RDF when LC publishes it.

Alternatively we were wondering whether FAST (Faceted Application of Subject Terminology)[1] might help. There was a project update [2] presented at ALA and it was announced that FAST will be made available as linked data in the spring of 2011.

Cheers

Corine

Hi Jeff,

As this coordination issue is complex indeed, this was not handled in SKOS. Instead it relies on specific extensions to be designed--this is MADS/RDF [1] is made for, in fact!
