Re: Anyone published mappings between DBpedia and subject vocabularies like IPTC, DDC, LCSH ?

Dear Johannes,

A couple of months ago you could have found an easy (but yet partial) answer to this by looking at this:
http://semantic.ckan.net/group/?group=http://ckan.net/group/lld
That's a graphic rendition on the Library Linked Data CKAN resource our LLD incubator group has started (http://ckan.net/group/lld)
(Un)fortunately now the graph is a bit messier than it was then ;-)

But by dragging things around you may see something. And the underlying data is still available through CKAN, in the links:dbpedia attributes (see for example at http://ckan.net/package/agrovoc-skos)
In principle all these datasets are published as Linked Data, so there should be a dump and/or a SPARQL endpoint available for them.

Good luck,

Antoine
