Hi Grant, When I click the link <http://www4.wiwiss.fu-berlin.de/drugbank/resource/drugs/DB00001> I get redirected to <http://wifo5-03.informatik.uni-mannheim.de/drugbank/resource/drugs/DB00001> (3 instead of 4), so it looks like the "resource" URIs are not stable. There is no <wifo5-03...> owl:sameAs <wifo5-04...> either so the resources could be different. The redirect URI should be stable ("Cool URIs don't change.").
In the page that is returned, I see owl:sameAs to DBpedia drugs, but those URIs include "www." which I believe is incorrect. I agree that shared URIs increase the value of different descriptions, but the Drugbank could use some changes too :) Besides, DBpedia extracts information from Wikipedia (only, AFAIK), so changes should be made there. I hope I made my point that the Drugbank uses inconsistent URIs, so if you do change Wikipedia, there may be people not agreeing to your edits for this reason.
