Hi all,

I have a problem with the following FED. I don't understand why this simple 
query from the bio2rdf::irefindex sparql endpoint works:

PREFIX bio2rdf-ifx: <http://bio2rdf.org/irefindex_vocabulary:>
SELECT  ?ppi ?protein_dgn ?protein_irx WHERE {
?ppi a bio2rdf-ifx:Pairwise-Interaction ;
        bio2rdf-ifx:interactor_a ?protein_dgn ;
        bio2rdf-ifx:interactor_b ?protein_irx .
} limit 20


HTTP SPARQL QUERY:
http://irefindex.bio2rdf.org/sparql?default-graph-uri=&query=PREFIX+bio2rdf-ifx%3A+%3Chttp%3A%2F%2Fbio2rdf.org%2Firefindex_vocabulary%3A%3E%0D%0ASELECT++%3Fppi+%3Fprotein_dgn+%3Fprotein_irx+WHERE+%7B%0D%0A%3Fppi+a+bio2rdf-ifx%3APairwise-Interaction+%3B%0D%0A+++++++bio2rdf-ifx%3Ainteractor_a+%3Fprotein_dgn+%3B%0D%0A+++++++bio2rdf-ifx%3Ainteractor_b+%3Fprotein_irx+.%0D%0A%7D+limit+20&format=text%2Fhtml&timeout=0&debug=on


And doing the same query from our isql shell works as well, but from our sparql 
endpoint (http://rdf.disgenet.org/sparql/) does not:

PREFIX bio2rdf-ifx: <http://bio2rdf.org/irefindex_vocabulary:>
SELECT  ?ppi ?protein_dgn ?protein_irx WHERE {
SERVICE <http://irefindex.bio2rdf.org/sparql> {
?ppi a bio2rdf-ifx:Pairwise-Interaction ;
        bio2rdf-ifx:interactor_a ?protein_dgn ;
        bio2rdf-ifx:interactor_b ?protein_irx .
}
} LIMIT 20

I've got data executing your SPARQL-FED query using our URIBurner instance [1]. What Virtuoso product are you using -- Open Source / Commercial and also what is its build version?

HTTP SPARQL QUERY:
http://rdf.disgenet.org/sparql/?default-graph-uri=&query=PREFIX+bio2rdf-ifx%3A+%3Chttp%3A%2F%2Fbio2rdf.org%2Firefindex_vocabulary%3A%3E%0D%0ASELECT++%3Fppi+%3Fprotein_dgn+%3Fprotein_irx+WHERE+%7B%0D%0ASERVICE+%3Chttp%3A%2F%2Firefindex.bio2rdf.org%2Fsparql%3E+%7B%0D%0A%3Fppi+a+bio2rdf-ifx%3APairwise-Interaction+%3B%0D%0A+++++++bio2rdf-ifx%3Ainteractor_a+%3Fprotein_dgn+%3B%0D%0A+++++++bio2rdf-ifx%3Ainteractor_b+%3Fprotein_irx+.%0D%0A%7D%0D%0A%7D+LIMIT+20&format=text%2Fhtml&timeout=0&debug=on


I am sure it is related to some configuration setting that we missed. Could you 
shed light on it?

Many thanks in advance!
Cheers,
Núria
