OWL2 RL + Apache Jena

In the context of realizing ontology reasoning on resource-constrained platforms [1], I created an OWL2 RL ruleset in SPARQL Construct format. Note that, to support all n-ary rules, the ruleset includes a set of auxiliary rules that, as a side-effect, generate intermediary (meaningless) inferences. If support for these n-ary rules is not required, these rules could be removed (last 9 rules).

You can find this ruleset here, and the accompanying axioms here.

To illustrate how to use Apache Jena and the OWL2 RL ruleset for ontology-based reasoning, I created a simple Java Maven project on GitHub. This could be an efficient alternative for those having performance issues with Jena’s built-in ontology reasoning support; seeing how OWL2 RL is an OWL2 profile that trades expressivity for performance.

(Note that I used my conversion web service to convert the OWL2 RL ruleset into the Apache Jena rule format.)

Check it out and let me know what you think!

Note that another post discusses how OWL2 RL can be utilized for ontology reasoning on the Android platform.
