I have the following code
data = TDBFactory.createDataset( dir.getAbsolutePath() );
data.begin( ReadWrite.WRITE);
// read 2 files into the model (approx 3.5K triples)
Model dataM = loadDir( ctxt, "/WEB-INF/resources/rdf/documents");
// read http://www.w3.org/2009/08/skos-reference/skos.rdf
Model schemaM = loadDir( ctxt, "/WEB-INF/resources/rdf/schemas" );
Reasoner reasoner = ReasonerRegistry.getOWLMiniReasoner();
reasoner = reasoner.bindSchema(schemaM);
infModel = ModelFactory.createInfModel(reasoner, dataM);
data.commit();
// DEBUGGING CODE
String realPath = ctxt.getRealPath("/WEB-INF/resources/");
File f2 = new File(realPath, "data.rdf");
// OOM occures here
infModel.write(new FileOutputStream(f2));
So my questions are:
1) Should in inferencing be done within a write transaction and if so how
does one assure that all inferencing will be done within a write
transaction? In this case I would expect that all inferencing would be
done in the infModel.write() call but in the general case I may not be
making that call.
2) Shoudn't the inferencing be writing to the TDB datastore? If so why is
there an OOM error?
Many thanks,
Claude
