Hello, I'm at a bit of a loss on this one. For some reason I'm getting the below exception most (but not all) of the time. On one occasion I printed out the triple being added in the org.topbraid.spin.model.SPINFactory.createTriplePattern(Unknown Source) call:
getTriplePattern triple: null http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://www.boeing.com/IVHM/ModelManagement.owl#Project One thing that's confusing is I don't understand why pellet is being invoked at all here. It's just converting the jena Query to a SPIN Query, right? Any ideas what might cause pellet to come into play? Here's the code leading up to the exception, with the sparql variable being a String and the memModel being just a jena OWL_MEM OntModel: Query selectQuery = QueryFactory.create(sparql, Syntax.syntaxARQ); ARQ2SPIN a2s = new ARQ2SPIN(memModel); org.topbraid.spin.model.Query spinQuery = a2s.createQuery (selectQuery, null); org.mindswap.pellet.exceptions.InternalReasonerException: Invalid value to create a literal.
