-------------------------------------------------------------------

I have tried this easy test:

Menu.owl: there is an individual "margherita" rdf:type Pizza
Food.owl: there are the classes Food and Pizza
recipe.txt: if(x rdf:type Pizza) -> (x rdf:type Food)

Result:
- reasoners/owl2/classify (Hermit): produces the inference that "margherita" is 
rdf:type Pizza and also Food. 
- reasoners/owl/classify (Jena): otherwise, dosn't prodoce the inference that 
"margherita" rdf:type Food
