Hello all, I am trying to use the SPIN API version 1.2.0 (developing in Eclipse) to execute functions I created in TopBraid Composer Maestro edition, version 3.5. I am using Ubuntu 11.10.
When I use the SPINInferences.run() method, I get warnings such as the following: "URI <http://topbraid.org/sparqlmotionfunctions#buildURI> has no registered function factory" Oddly, I also get these warnings for rules/functions I have created and defined *within* my SPIN RDF file. Here is the Java code where I create a Jena model and load my SPIN RDF file: OntModel mySPINModel = ModelFactory.createOntologyModel( OntModelSpec.OWL_MEM ); mySPINModel.read("http://localhost/tmp/myrules.spin.rdf";); I had read about a similar problem here :http://www.mail-archive.com/[email protected]/msg01770.html, and I am importing the SPARQL Motion functions. I have tried this in two different ways: (1) By including the relevant imports in the SPIN RDF file: <owl:Ontology rdf:about=""> <owl:imports rdf:resource="http://spinrdf.org/spin"/> <owl:imports rdf:resource="http://spinrdf.org/spl"/> <owl:imports rdf:resource="http://topbraid.org/functions-smf"/> <owl:imports rdf:resource="http://topbraid.org/functions-afn"/> <owl:imports rdf:resource="http://topbraid.org/functions-fn"/> </owl:Ontology> (2) By reading them directly into the Jena model: mySPINModel.read("http://spinrdf.org/spin";); mySPINModel.read("http://spinrdf.org/spl";); mySPINModel.read("http://topbraid.org/functions-smf";); mySPINModel.read("http://topbraid.org/functions-afn";); mySPINModel.read("http://topbraid.org/functions-fn";); Neither approach fixes the problem, and as a result SPINInferences.run() doesn't infer any new triples (unlike when I execute my rules within TopBraid Composer 3.5.0). Where am I going wrong? Any help with this issue would be much appreciated, Alison -- You received this message because you are subscribed to the Google Group "TopBraid Suite Users", the topics of which include TopBraid Composer, TopBraid Live, TopBraid Ensemble, SPARQLMotion and SPIN.
