I have an example about ontology with only class Person and a try to create a collection throw sqwrl:makeBag
Person(?p) ˚ sqwrl:makeBag(?bag, ?p) ˚ sqwrl:size(?size, ?bag) -> sqwrl:select(?size)
And I have 4 individuals with type Person but when I run the query result is 1. I don't know why please help me thanks so much
