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
That's not a *minimal* example!
It's quite hard to see what you are trying to do with model and
inferenceModel. The inferenceModel is created over the top of model and
yet you also add inferenceModel back into model at various stages. Very
circular and probably not what you mean.
You seem to set derivation logging on model, rather than inferenceModel
during createConsult and then set derivation logging on inferenceModel
only at the start of executeInference. At least for the first cycle this
will be after inference is complete and so there's no derivations left
to make and nothing will be logged for that iteration.
Can I suggest that you start with a simpler test case.
Just create a single InfModel over your rules.
No fiddling with the base model.
Set derivation logging on at creation time.
Then add a data sample and check that derivations are logged.
If you try that and it works then you know the Jena machinery works the
way you are using it and you can incrementally extend your code to do
what you want it to do. If if doesn't work then you have a test case we
can take a look at without having work out the rest of your code :)
Cheers,
Dave
