JenaOntologyImpl

public JenaOntologyImpl()

Method Detail

init

public Resource init()
              throws ResourceInstantiationException

Description copied from class: TaxonomyImpl

Initialises this resource, and returns it.

Specified by:

init in interface Resource

Overrides:

init in class TaxonomyImpl

Throws:

ResourceInstantiationException

getActions

public List getActions()

Description copied from interface: ActionsPublisher

Returns a list of Action objects. This method will be called everytime a menu for this resource needs to be built, thus allowing for dynamic updates to the list of actions. A null value in this list will cause a separator to be created.

Specified by:

getActions in interface ActionsPublisher

Returns:

a List of Actions.

load

public void load()
          throws ResourceInstantiationException

Loads the ontology from an external file.

Specified by:

load in interface Taxonomy

Overrides:

load in class TaxonomyImpl

Throws:

ResourceInstantiationException

load

public void load(URL inputURL,
                 int ontologyType)
          throws ResourceInstantiationException

Loads ontological data of a given type from a URL.

Parameters:

inputURL - the URL for the file to be read.

ontologyType - the type of ontology (one of OWL_LITE, OWL_DL, OWL_FULL, RDFS or DAML).

Throws:

ResourceInstantiationException

save

public void save(File outputFile,
                 int ontologyType)

Saves the ontology to a file.

Parameters:

outputFile - the file to write to.

ontologyType - the output format to write.

toJenaClassRec

protected void toJenaClassRec(OClass aGateClass,
                              com.hp.hpl.jena.ontology.OntModel jenaModel,
                              com.hp.hpl.jena.ontology.OntClass parentClass)

Converts a GATE class and all its subclasses (recursively) to Jena classes and adds them to the Jena model provided.

Parameters:

aClass - the GATE class to be converted.

jenaModel - the Jena model to be populated.

parentClass - the parent of the GATE class in the Jena model. If null then the created Jena class will be marked as a top class.

convertoToGateClasses

protected Set convertoToGateClasses(Iterator jenaIterator)

toGateClassRec

protected void toGateClassRec(com.hp.hpl.jena.ontology.OntClass jenaClass,
                              OClass parent)

Converts a Jena class and all its subclasses to GATE classes and adds them to this ontology.

Parameters:

aClass - the Class in Jena model

parent - the parent class for the class to be added in this ontology.

cleanup
