"object property hasComplexity (its values are 1,2,3,4,5)"
-> why do you say it's an object property if the values are numerical?
Moreover, you compare two different queries and then say one works in
Protege, the other not. That is a totally useless statement. It should
be clear that you should compare the SAME queries
It remains open what kind of RDF term the complexity values
are...literals or resources
