Hi Grant,
in addition to what Ben mentioned, you can still get the required
results using the following query:
PREFIX dbpedia-owl: <http://dbpedia.org/ontology/>
PREFIX dbpprop: <http://dbpedia.org/property/>
PREFIX drugbank:
<http://wifo5-04.informatik.uni-mannheim.de/drugbank/resource/drugbank/>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
SELECT * WHERE{
{
SELECT * WHERE {
SERVICE
<http://wifo5-04.informatik.uni-mannheim.de/drugbank/sparql>
{?modifiedDrug rdfs:label "Lepirudin";
drugbank:affectedOrganism ?affectedOrganism}
}
}.
{
SELECT IRI(REPLACE(STR(?drug),
"http://www4.wiwiss.fu-berlin.de";,
"http://wifo5-04.informatik.uni-mannheim.de";)) AS ?modifiedDrug WHERE {
SERVICE <http://dbpedia.org/sparql>
{?a rdfs:label "Lepirudin"@en; owl:sameAs ?drug;
dbpprop:routesOfAdministration ?routes.}
}
}
}
Hope it helps.

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.
Regards,
Ben
