drugbank2pubcehm

Hi,

I'm playing with the following query but I get the empty result set.

PREFIX n3: <http://bio2rdf.org/drugbank_vocabulary:>
SELECT *
WHERE {
?s a n3:Drug;
n3:xref ?pubchem .
}
LIMIT 100

I use the http://virtuoso.openlifedata.org/sparql endpoint.

I kindly ask for help.

Best, Andrej

There are two predicates to link between drugbank and pubchem records;

http://bio2rdf.org/drugbank_vocabulary:x-pubchemcompound

http://bio2rdf.org/drugbank_vocabulary:x-pubchemsubstance

so

PREFIX n3: <http://bio2rdf.org/drugbank_vocabulary:>

SELECT *

WHERE {

  VALUES ?p {n3:x-pubchemcompound n3:x-pubchemsubstance}

  ?s a n3:Drug.

  ?s ?p ?o .

}

LIMIT 100
