Reported by tomheath: The FU Berlin has published a version of DBLP that does HTTP303 redirects and Content Negotiation on the URIs of papers: http://www4.wiwiss.fu-berlin.de/dblp/
So for example, a paper may have the URI: http://www4.wiwiss.fu-berlin.de/dblp/resource/record/conf/aaai/StaabADEHMSSS00 on this site, which is the same publication as that described in the HTML page: http://www.bibsonomy.org/bibtex/1fe131db0ba88d5bba1220ba3912199c9
If Bibsonomy did HTTP303 redirects on URIs such as: http://www.bibsonomy.org/bibtex/1fe131db0ba88d5bba1220ba3912199c9 (as discussed in item 338) then we could say that:
I understand that Bibsonomy retains the mapping of Bibsonomy hash identifiers to DBLP identifiers, in which case making these mappings automatically should be trivial. If these owl:sameAs statements could be automatically included in the RDF descriptions of items on Bibsonomy, such as: http://www.bibsonomy.org/burst/bibtex/1fe131db0ba88d5bba1220ba3912199c9 that would be very very cool.
