me.RegardsAbdul

Subject: Re: OWL2 Support in Jena
Abdul,
You might be interested in this tool I wrote that converts OWL 2 ontologies to
Jena rules:
https://github.com/balhoff/owl-to-rules
<https://github.com/balhoff/owl-to-rules>
It’s limited to axioms in the OWL 2 RL profile
(https://www.w3.org/TR/2012/REC-owl2-profiles-20121211/#OWL_2_RL
<https://www.w3.org/TR/2012/REC-owl2-profiles-20121211/#OWL_2_RL>). Also, it is
meant to produce Abox inferences only. For example, if your ontology has <A>
rdfs:subClassOf <B>, and <B> rdfs:subClassOf <C>, the rules will not output <A>
rdfs:subClassOf <C>. However, any instances of <A> in your dataset will be
inferred to be instances of <C>.
It supports some useful things from OWL 2 such as property chains, and also
SWRL rules. But there are some unfinished parts; it doesn’t do anything with
data properties (I haven’t needed it so far). It also doesn’t yet support any
SWRL built-ins or OWL 2 keys.
It’s written in Scala but you can use it in Java programs.
Best regards,
Jim Balhoff
