Hi Juan
My strategy is as following
Q1 : Which types are used?
SELECT DISTINCT ?type
WHERE {?x rdf:type ?type}
Q2 : Which predicates are used?
SELECT DISTINCT ?p
WHERE {?x ?p ?o}
Q3 : Which predicates are used by instances of the type :foo found in Q1
I'm interested in
SELECT DISTINCT ?p
WHERE {?x ?p :foo}
