OWLAPI-Jena Integration

This repository contains an exemplary application integrating OWLAPI and Jena libraries. In particular the application:

1. loads an ontology passed as argument;
2. loads the ontology imported using owl:imports assertions;
3. infers all implicit assertions using HermiT reasoner;
4. transforms the inferred ontology into a Jena model;
5. evaluates a query (i.e. SELECT ?i ?c {?i a ?c}) on the Jena model and prints the results.

Installation and usage

You can install (i.e. mvn clean install) and run (i.e. mvn exec:java -Dexec.cleanupDaemonThreads=false -Dexec.mainClass="it.cnr.istc.stlab.App" -Dexec.args="[ONTOLOGY IRI]" ) the application using maven.

You can also use this tool to derive the inferred version of any ontology using HermiT reasoner. To do so:

1. Compile the project mvn clean install
2. Run the main in GetInferredOntology class mvn exec:java -Dexec.cleanupDaemonThreads=false -Dexec.mainClass="it.cnr.istc.stlab.GetInferredOntology" -Dexec.args="[ONTOLOGY IRI] /path/to/the/output/ontology.ttl" (the inferred ontology will be written in Turtle format).

Note: [ONTOLOGY IRI] can be either local paths (e.g. file:///path/to/the/input/ontology.owl) or URLs (e.g.http://www.ontologydesignpatterns.org/ont/dul/DUL.owl)
