Hi! I need to store negated property paths using the SPIN API (), however, although ARQ parses the queries just fine I'm unable to use them to create SPIN queries. I'm using the latest version of the SPIN API (2.0.0). To exemplify:
# Using negated paths to mimic wildcard String qString = "PREFIX : <http://example#> SELECT ?target WHERE { :start (:|!:)* ?target }"; Query query = QueryFactory.create(qString); ARQ2SPIN arq2SPIN = new ARQ2SPIN(model); org.topbraid.spin.model.Query spinQuery = arq2SPIN.createQuery(query, null); This gives rise to the exeption: Exception in thread "main" java.lang.IllegalArgumentException: Unsupported Path element: !<http://example#> of type class org.apache.jena.sparql.path.P_NegPropSet at org.topbraid.spin.arq.ARQ2SPIN.createPath(ARQ2SPIN.java:798) at org.topbraid.spin.arq.ARQ2SPIN.createPath(ARQ2SPIN.java:769) at org.topbraid.spin.arq.ARQ2SPIN.createMod(ARQ2SPIN.java:804) at org.topbraid.spin.arq.ARQ2SPIN.createPath(ARQ2SPIN.java:741) at org.topbraid.spin.arq.ARQ2SPIN.access$200(ARQ2SPIN.java:130) at org.topbraid.spin.arq.ARQ2SPIN$1.visitElements(ARQ2SPIN.java:609) at org.topbraid.spin.arq.ARQ2SPIN$1.visit(ARQ2SPIN.java:552) at org.apache.jena.sparql.syntax.ElementPathBlock.visit(ElementPathBlock. java:89) at org.topbraid.spin.arq.AbstractElementVisitor.visit( AbstractElementVisitor.java:82) at org.topbraid.spin.arq.ARQ2SPIN$1.visit(ARQ2SPIN.java:498) at org.apache.jena.sparql.syntax.ElementGroup.visit(ElementGroup.java:120) at org.topbraid.spin.arq.ARQ2SPIN.createElementList(ARQ2SPIN.java:454) at org.topbraid.spin.arq.ARQ2SPIN.createQuery(ARQ2SPIN.java:905) Are negated property paths not supported in SPIN API at this point? I also looked at the vocabulary specification and couldn't find anything that indicated that it is supported.
