Hi Dave, Thanks. I've created a small ontology and set of rules which are fired (I print the results and I saw that is making the inference correctly). I checked if derivation is switched on (I've executed setDerivationLogging to true)) and the files continue empty..!!
This is the full code that I'm using: OWLInferenceManager: http://pastebin.com/trQVtv1s Consult: http://pastebin.com/nCnT0nBa Main: http://pastebin.com/UduJ2nXY The ontology: http://pastebin.com/1QkrknMr The rules: http://pastebin.com/JPT3UZSi And the output (that confirms that rules are fired, but no derivation is logged): http://pastebin.com/HA06pYmX Thanks for your help!
