[protege-owl] aggregating over group members

Hi James,

you could use John, Jane and Susy as nominals and then declare the  
class Family to be equivalent to {John,Jane,Susy}. If you also say  
that all three family members like Macaroni and then ask for  
subclasses of "likesFood value Macaroni", you will get "Family" as  

However, reasoning with nominals is usually hard, so it might be worth  
looking into other ways of representing this closing of your knowledge.
