Hi,
I have a problem with a SPARQL, I try to find a valid query for SPARQL 1.0
through Virtuoso 06.01.3127 for doing a query like this :
INSERT { GRAPH <http://my/graph> { ?s <http://my/ontology/indegree>
count(?x) }} where {
GRAPH <http://my/graph> {
?x ?p ?s .
?s a <http://my/ontology/Person>
}
}
Most precisely I try to add a triple which represents the number of triples
which have for object a same subject for each person. For example for this
graph :
<http://Person/1> <http://my/ontology/knows> <http://Person/2> .
<http://Person/3> <http://my/ontology/isBossOf> <http://Person/2> .
<http://Person/4> <http://my/ontology/isFatherOf> <http://Person/2> .
The result must be the triple : <http://Person/2> <
http://my/ontology/indegree> "3" .
Anyone knows how to do this easily just with a query ?
Thanks in advance.
Julien.
