[Pellet-users] Fwd: Property chain with reasoning

[Jaroslaw Slawinski]

Hello!

I have a problem with the pair Protege4 and Pellet (with OWL 1.1).
I have created a small owl file in Protege 4. I have used OWL 1.1 feature -
the property chain.
Now if I load the file to Pellet (1.5.2 version) I got "Unsupported axiom:
Ignoring triple with unknown property from OWL namespace:" warning. I also
tried to change manually owl:propertyChain to owl2:propertyChain - but the
reasoner does not reason the chain property.

I know that the issue was on the list (
http://lists.owldl.com/pipermail/pellet-users/2008-May/002659.html) but
maybe some solution could be given (changing namespaces by hand? - if it
could be a solution: how?) or a suggestion when Pellet will be able to
understand the owl2 namespace?

BTW: how does Protege 4 do it that reasoning with Pellet is correct? Maybe I
need use newer libraries (Jena/OWLAPI)?

Best regards,

Jarek
