[open-bibliography] New BNB sample data available

Thu Feb 3 20:07:05 UTC 2011

It would be nice if the constructed heading could have references to the component LCSH concepts. 

It seems unfortunate that skos:OrderedCollection and skos:Concept are disjoint. If they weren't, then the component concepts could be listed in a skos:memberList. Barring that, I could imagine a new SKOS property like this to expression the coordination:

skos:coordinates a owl:ObjectProperty ;
	rdfs:domain skos:Concept ;
	rdfs:range skos:OrderedCollection .
