[Pellet-users] Pattern data range restriction does not appear to work on xsd:string

[Arthur Peters]

I am playing with pattern restrictions and I found that they do not work on
string property. When I ask the reasoner to do anything with such a
restriction I get the following warning logged:

WARN [main] (PelletVisitor.java:851) - Unrecognized base datatype string

I have attached a small program that shows this behavior.

A little investigation shows that in
PelletVisitor.visit(OWLDataRangeRestriction
node) nothing useful happens unless "baseDatatype instanceof XSDAtomicType"
and the class that is used for strings (XSDString) does not implement that
interface. This seems a bit odd to me.

Thanks for all of your work on pellet. It's a great library.
