Andy,
I'm having trouble getting rid of all my ^^ noise.
I run Jena schemagen against an Ontology that has no type annotations,
I don't see any in the output of schemagen, but calls to
entityRef = model.createIndividual(entityUri, oclass);
entityRef.addLiteral(Rex.hasEntityDetectionSource, source);
entityRef.addLiteral(Rex.hasNormalizedText, normalizedText);
entityRef.addLiteral(Rex.hasOriginalText, rawText);
end up adding the ^^ and the string data type.
I suppose I'm missing something stupid?
