Some RDF vocabs do go down this route, with 'hasAge', 'hasName',
'hasHomepage' instead of 'age', 'name', 'homepage'. While
backwards-named properties like 'subClassOf' complicate the picture,
I prefer to have simple property names. I think an analogy with OO
class/property models is appropriate here (it isn't always, with RDF).
In Java, a Person class might have 'age', 'name', 'homepage' as fields 
or bean properties. Similarly in other objects. The fact that the 
property is attached to some object is enough to suggest the implicit 
'has'. Unfortunately, 'has-subClassOf' doesn't quite work, raising 
intuitions that the thing referenced is a sub-, rather than super- 
class of the subject resource. 

If we can minimise the deployment of 'isXYZof' properties, we can
hopefully get away without having to prefix everything else with
'has'. Perhaps... :)
