Pellet is not part of the Apache Jena distribution - it's developed, licensed and distributed separately. So you need check with the Pellet folks for the definitive answer. My understanding [1] is that Pellet is dual licensed AGPL/Commercial so the key question you have to decide is whether yo

Jena reasoner questions

2015-12-08 Thread Chris Snyder
I have a few reasoner questions. 1) I’m using the latest version of Jena 3.0.0 is it true that the only way to use SWRL rules is with an external reasoner? My concern is how I would use Protege which can handle adding SWRL rules and then processing the ontology with Jena. 2) I tried to integr

Hi Chris, Maybe I'm not an expert to answer you properly, but I've being working with this kind of scenario (Ontologies, SWRL, jena, owlapi) lately and here is what I can share: 1) Yes. As far as I know, Jena doesn't have native support for SWRL. 2) The most recent versions of pellet I've seen i
