LiteralOrONodeID	A class representing something that is either a literal or a node ID.
MaxCardinalityRestriction	A MaxCardinalityRestriction.
MinCardinalityRestriction	A MinCardinalityRestriction.
ObjectProperty	ObjectProperty is a sub type of the RDFProperty.
OBNodeID	An object representing an ontology node ID.
OClass	Each OClass (Ontology Class) represents a concept/class in ontology.

OInstance	OInstance (Ontology Instance) represents an instance in the ontology/knowledge base.
ONodeID	An ONodeID represents the id of either a blank node or a resource.
Ontology	Interface for ontology language resources.
OntologyBooleanQuery	This represents a boolean query of the triple store for the ontology.
OntologyModificationListener	Objects wishing to listen to various ontology events, must implement this interface (using implements java keyword) and the methods of this interface.
OntologyTripleStore	An OntologyTripleStore object can be used to directly manipulate the triples that represent an ontology, if the ontology implementation supports this.
OntologyTripleStoreListener	An OntologyTripleStoreListener is noticed whenever a triple is added to or removed from the ontology store.
OntologyTupleQuery	This represents a tuple query of the triple store for the ontology.
OResource	This is the top level interface for all ontology resources such as classes, instances and properties.
OURI	Interface for objects representing an URI.
OValue	A class representing something that is either a literal or a OResource.
RDFProperty	RDFProperty is the top level property.
Restriction	This interface defines a restriction in the ontology.
SomeValuesFromRestriction	A SomeValuesFromRestriction.
SymmetricProperty	Every SymmetricProperty is ObjectProperty.
TransitiveProperty	Interface for transitive properties.
Triple	A Triple represents an RDF Triple from the underlying triple store and consists of a subject, predicate and object.

Class Summary

DataType	This class provides a list of datatypes, supported by the ontology API.
Literal	The class Literal represents a literal value as defined in section 6.5 of http://www.w3.org/TR/rdf-concepts .
OConstants.OWL	All predefined URIs from the OWL1 namespace.
OConstants.RDF	All predefined URIs from the RDF name space.
OConstants.RDFS	All predefined URIs from the RDFS name space.
OConstants.XMLSchema
OntologyUtilities	Deprecated. the use of this class and all its methods should be avoided in the future.
OUtils
URI	Deprecated. Use OURI objects and the Ontology factory methods for creating them instead.
Utils

Enum Summary

OConstants.Closure	Closure constants.
OConstants.OntologyFormat	A list of serialization formats for ontologies.
OConstants.QueryLanguage

Exception Summary

GateOntologyException	Exception used to signal an gate ontology exception within Gate.
InvalidURIException	This exception is thrown when a URI is not valid.
InvalidValueException	This exception should be thrown when a property value is not compatible with the property. e.g. boolean value for the integer datatype, invalid instance for an object property.
