[Pellet-users] Namespaces for SWRL

[Matt Williams]

Dear All,

I'm having problems with the swrl namespace.

I've looked at the pellet RulesExample file, which I can compile & run 
fine, but looking at the ontology that it uses, I can't see where all 
the different NS (dl-safe & swrl) get declared.

Then when I try & add a rule to my ontology, I get complaints about "the 
prefix swrl for the element swrl:Imp is not bound".

I've tried declaring swrl as a NS using 
xmlns:swrl="http://www.w3.org/2003/11/swrl"/ or importing a variety of 
potential swrl ontologies (from Christine Golbriech's Family ontology) 
noe of which helps.

Could someone point out what I should be doing?

There was reference to this in a earlier post (2004, I think) but it 
wasn't really ever tied up (or at least I didn't understand it).

Thanks a lot,

Matt
