RE: OWL Web Ontology Language

Hi Peter,

What do you understand when someone tells you that Ford produces Mustangs?
They produce also other models, they may or may not outsource all or part
(most "US" products come from China), but one thing is certain: Ford
produces Mustangs, one way or the other.

Forgive me my ignorance: what do you mean with 'partial'? I scanned through
the W3C Recommendations but could not find it.

The code you show may not be correct, but I accept that you know more of OWL
than I do. The rdf:range of someValuesFrom is rdfs:Class, and Ford is an
Individual. How do you match that?

Regards,

Hans

Well, again, just what do you mean here?  Does Ford manufacture the class of
Mustangs?  Does Ford manufacture some Mustangs?  Does Ford manufacture all
Mustangs?  Does Ford necessarily manufacture all Mustangs?

What you probably want to say is something like

Class(Manufacturer partial)
Individual(Ford type(Manufacturer))

ObjectProperty(manufactured-by Functional)

Class(Car partial)

Class(Mustang partial Car restriction(manufactured-by someValuesFrom(Ford)))
