+1 for excluding the class domains in the URIs of multiple classes 
spanning properties, i.e., a name is a name is a name. A human user and 
also a machine will get the relation (specific meaning) of name via its 
context, i.e., the types of that resource, e.g., schemaorg:Person => a 
person's name etc.

PS: otherwise we would probably end up with something the like the 
Freebase vocabulary ;)
