Hi Frank,

As the famous Pizza ontology states:

It is important to realise that in
OWL domains and ranges should not be viewed as constraints to be checked. They
are used as `axioms' in reasoning. For example if the property hasTopping has the
domain set as Pizza and we then applied the hasTopping property to IceCream
(individuals that are members of the class IceCream), this would generally not
result in an error. It would be used to infer that the class IceCream must be a
subclass of Pizza!

Hope this helps.

Subject: Property vs. restriction
Hi,
I try to model with OWL. My question is: 
Instead of using a restriction, do I get the same result by specifying a property with  specific domain and range?
What is assumed as “best practice” of modeling relationships between concepts?

Thanks for your help!
