Dave Reynolds will be able to say more, but my understanding is that inferred triples are _not_ added to the model in the sense in which we might use Model::add to add a Statement. They are simply presented by the implementation as the model is scanned, "injected" by the inference machinery, so to speak.
As for your use case, perhaps you could use a rule to do this? Again, I don't know a lot about this end of Jena, but perhaps you could write a custom built-in function for the rules system [1] . ajs6f [1] https://jena.apache.org/documentation/inference/index.html#builtins > On Jan 7, 2019, at 10:32 AM, Nouwt, B.
