Hello everyone,
maybe for most of you this is a trivial question, but i'm loosing a
lot of time trying to solve it by my self :)
My task is to find avery connected resource to a given resource, i
have this query:
SELECT ?resource WHERE { <given resource URI> ?link ?resource. }
this way i get the value of every singe property, both other resources
and literal/numbers etc.
I'd like to filter all the non-resource results. By now i thought of 2
solutions:
1. Making a union of a lot of there queries substituting ?link with a
specific predicate, but this would be an enormous query;
2. using FILTER (?link = predicate1 || ?link = predicate2 || ...) and
so on, but the problem is the same, i have to list every single
predicate that is useful to me.
Is there a way to automatically filter between resources and literal/
number values?
Thankyou,
Piero Molino
