There are two ways to generate a Jena model from a Protege-OWL model using the API:

__TOC__

== Get a snapshot of the current Protege-OWL model as a Jena OntModel ==

You can do this by calling the <code>getOntModel()</code> method from the [http://protege.stanford.edu/download/prerelease_javadoc_owl/edu/stanford/smi/protegex/owl/jena/OntModelProvider.html OntModelProvider] interface. This interface is implemented both by [http://protege.stanford.edu/download/release-javadoc-owl/edu/stanford/smi/protegex/owl/jena/JenaOWLModel.html JenaOWLModel] and [http://protege.stanford.edu/download/release-javadoc-owl/edu/stanford/smi/protegex/owl/database/OWLDatabaseModel.html OWLDatabaseModel]. This [http://protege.stanford.edu/plugins/owl/api/guide.html#Jena approach is described] in the Protege-OWL API Programmer's Guide.

Sample code:

<pre>JenaOWLModel owlModel = ProtegeOWL.createJenaOWLModel();

OWLClass protegeCls = owlModel.createOWLNamedClass("MyClass");
OWLDatatypeProperty protegeProp = owlModel.createOWLDatatypeProperty("prop");

protegeCls.setPropertyValue(protegeProp, "aaa");
//Protege: MyClass.prop = "aaa"

//get the Jena OntModel
Model jenaModel = owlModel.getOntModel();
String namespace = owlModel.getNamespaceManager().getDefaultNamespace();

Resource jenaCls = jenaModel.getResource(namespace + "MyClass");
Property jenaProp = jenaModel.getProperty(namespace + "prop");
//Protege: MyClass.prop = "aaa"
//Jena: MyClass.prop = "aaa" (same value because it is a snapshot)

//Protege: MyClass.prop --> "bbb"
protegeCls.setPropertyValue(protegeProp, "bbb");
//Protege: MyClass.prop = "bbb"
//Jena: MyClass.prop = "aaa" (not synchronized)

//Jena: MyClass.prop --> "ccc"
jenaCls.addProperty(jenaProp, "ccc");
//Protege: MyClass.prop = "bbb"
//Jena: MyClass.prop = "ccc" (not synchronized)</pre>

== Get a live and synchronized copy of the Protege-OWL model as a Jena Model ==

You can do this by calling the <code>getJenaModel()</code> method from the [http://protege.stanford.edu/download/release-javadoc-owl/edu/stanford/smi/protegex/owl/model/OWLModel.html OWLModel] interface. The synchronization of the two models is one-directional. If you make a change to the Protege-OWL model, the change is reflected in the Jena model, but not the other way around. If you try to change the Jena model by using the Jena API, you will get a runtime exception that the operation is not supported. This is [http://protege.stanford.edu/plugins/owl/jena-integration.html documented in more detail] on the Protege Web site.

Sample code:

<pre>JenaOWLModel owlModel = ProtegeOWL.createJenaOWLModel();

OWLClass protegeCls = owlModel.createOWLNamedClass("MyClass");
OWLDatatypeProperty protegeProp = owlModel.createOWLDatatypeProperty("prop");

protegeCls.setPropertyValue(protegeProp, "aaa");
//Protege: MyClass.prop = "aaa"

Model jenaModel = owlModel.getJenaModel();
String namespace = owlModel.getNamespaceManager().getDefaultNamespace();

Resource jenaCls = jenaModel.getResource(namespace + "MyClass");
Property jenaProp = jenaModel.getProperty(namespace + "prop");
//Protege: MyClass.prop = "aaa"
//Jena: MyClass.prop = "aaa"

//Protege: MyClass.prop --> "bbb"
protegeCls.setPropertyValue(protegeProp, "bbb");
//Protege: MyClass.prop = "bbb"
//Jena: MyClass.prop = "bbb" (same value because they are synchronized)

//Jena: MyClass.prop --> "ccc"
jenaCls.addProperty(jenaProp, "ccc");
//Exception -> java.lang.RuntimeException: Not supported yet</pre>
