I've got other ways to do this, but it is nagging at me that I can't
figure out how to express this in sparq.
I've got a graph with many reified statements.
So, consider this where clause fragment, selects all the statements
that make up all the reifications. What I want is to end up with:
?sub ?pred ?obj ?count-of-this-triple
in the select list.
GRAPH <urn:jug:global> {
?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
<http://www.w3.org/1999/02/22-rdf-syntax-ns#Statement> .
?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#object> ?sub .
?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#predicate> ?pred .
?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#object> ?obj .
}
