Surely 'Boolean ISA Integer' translates to 'all operations that can 
consume an integer can consume a boolean' which is clearly wrong, at 
least from my perspective. You might implement a boolean as an 
enumeration but it shouldn't look like that in the ontology. I would be 
very surprised (as a user) if I asked what I could do with a boolean 
operator and got multiplication as an answer...
