OWL Elements

Toolbox Icon	Description
Ontology	The OWL ontology Package, which holds all the OWL modeling elements. You can export the contents of this Package to produce the Ontology XML document.
Class	An extended UML Class that represents an OWL Class that describes an instantiatable entity with properties and semantic meaning.
Data Range	An extended UML Enumeration that defines a collection of values for an OWL Property.
Enumerated Class	An extended UML Class that defines an OWL Class extension defined by any one of the range of the allowed OWL Individuals.
Restriction	An extended UML Class that defines an OWL Class extension as restricted by the specified property and its allowable values.
Singleton	An extended UML Class, representing an OWL Class for a specific OWL Individual.

OWL Properties (Elements)

Toolbox Icon	Description
Annotation	An extended UML Class, representing an OWL Annotation Property definition.
Datatype Property	An extended UML Class, representing an OWL Datatype Property definition.
Object Property	An extended UML Class, representing a semantic OWL Property definition.
Ontology Property	An extended UML Part, representing a property defined on the OWL Ontology.
Individual	An extended UML Object, representing an instance of an OWL Class that defines an individual fact.
Value	An extended UML Part, holding a value defined in an OWL Property or OWL Individual.

OWL Relationships

Toolbox Icon	Description
Imports	An extended UML PackageImports, that enables an OWL ontology to reference another OWL Ontology.
Domain	An extended UML Association, that specifies the OWL Classes that apply the specified OWL Property (Annotation, Datatype or Object Property).
Range	An extended UML Association, that specifies the OWL Class with the value type applicable to the specified OWL Property (Annotation, Datatype or Object Property).
Inverse Of	An extended UML Association, between two opposing, but related OWL Property elements.
Sub Property Of	An extended UML Generalization between two OWL Property elements.
Subclass Of	An extended UML Generalization between two OWL Class elements.
Value	An extended UML Association, defining an OWL Property and value between OWL Classes.

OWL Semantics (Relationships)

Toolbox Icon	Description
All Different	An extended UML Dependency between different (that is, unique) OWL Individuals typed by the same OWL Class.
Backward Compatible With	An extended UML Dependency between an OWL Ontology and another that it is backward compatible with.
Complement Of	An extended UML Dependency between an OWL Class and its complement (or opposite).
Different From	An extended UML Dependency between two semantically different OWL Individuals typed by the same OWL Class.
Disjoint With	An extended UML Dependency between two OWL Classes that have no common individuals.
Equivalent Class	An extended UML Dependency between two equivalent OWL Classes.
Equivalent Property	An extended UML Dependency between two equivalent OWL Property elements.
Incompatible With	An extended UML Dependency between an OWL Ontology and another that it is incompatible with.
Intersection Of	An extended UML Dependency between an OWL Class and others it also specializes.
Ontology Property	An extended UML Dependency, representing a property defined on the OWL Ontology.
Prior Version	An extended UML Dependency between an OWL Ontology and its predecessor.
Same As	An extended UML Dependency between two semantically identical OWL Individuals typed by the same OWL Class.
Union Of	An extended UML Dependency between a general OWL Class and others that distinctly specialize it.
