Method Detail

getBaseModel

com.hp.hpl.jena.rdf.model.Model getBaseModel(com.hp.hpl.jena.ontology.OntModel ontModel)

Gets the base model of a given OntModel. The OntModel must be know to the registry. This method is preferred over OntModel.getBaseModel() which had a bug in Jena 3.1, and is furthermore inefficient as it creates a new model on each call.

Parameters:

ontModel -

Returns:

getInferenceModel

com.hp.hpl.jena.rdf.model.Model getInferenceModel(com.hp.hpl.jena.ontology.OntModel ontModel)

getOrLoadOntModel

com.hp.hpl.jena.ontology.OntModel getOrLoadOntModel(java.net.URI baseURI)
                                                    throws java.lang.Exception

Gets an existing OntModel with a given base URI. If the model does not exist yet, it will create it on demand.

Parameters:

baseURI - the base URI - must be registered in the workspace

Returns:

the existing or new OntModel

Throws:

java.lang.Exception - on load errors

getSystemModel

com.hp.hpl.jena.rdf.model.Model getSystemModel(com.hp.hpl.jena.ontology.OntModel ontModel)

listOntModels

java.util.Iterator<com.hp.hpl.jena.ontology.OntModel> listOntModels()

Lists all available OntModels (for all sessions).

Returns:

an Iterator of OntModels

listOntModels

java.util.Iterator<com.hp.hpl.jena.ontology.OntModel> listOntModels(com.hp.hpl.jena.graph.Graph graph)
