Hi Alan,
I saw that with Jean help (thank you Jean!) you already solved the
problem related to the above exception.
The idea behind Rio was to move to a light rdf parser as Jena was havyly
underused (Rio is about 150K against about 3Mb of Jena, this sounds
good with web start). In fact, RDQL and other features are not used in
welkin at all. That because welkin is going probably to be a
visualization tool only, while facetting will be performed by other
applications like Longwell.
