I have a question concerning results of SPARQL queries.
My code: pastebin.com/71Bwn3mc
When I run this query, I get three results: [6, 12], [6, a.Pizza], [a.has_topping, a.cheese1]
I know that this number 6 is some representation of a "is_a" property which probably has different namespace, and I'm guessing 12 is for "owl:Thing".
If I remember correctly, before the new update instead of these integers were None values.
My question is : how could I avoid these results or at least make them readable?
