If I wasn;t clear enough about this example: An ontology aware system
doesn't care at all about these two forms, they are identical as far as
it is concerned -- even if we don't explicitly label the <object> as a
<Person> the system knows that we are dealing with a <Person> because
only people have <SSNs>
This is where ontologies allow you to be *more flexible* in how data is
exchanged -- as long as the system has the knowledge to figure it out
it will..
