Hello,
I'm getting an exception on the call to registerAllSPINModules
(stack trace below). Stepping through the code, it's happeining on
the following spin:Function defined in the spl ontology (spl.spin.owl):
http://spinrdf.org/spl#hasValue
I'm not quite sure how to debug this one. I believe I have the latest
downloads of the spin libs and models. Any ideas?
