Protege-OWL Architecture OWL GUI Plugins (SWRL Editors, ezOWL, OWL Extension APIs OWLViz, Wizards, etc.) (SWRL, OWL-S, etc.) OWL Plugin Protégé OWL GUI (Expression Editor, Protégé OWL API Conditions Widget, etc.) (Logical class definitions, restrictions, etc.) Jena API (Parsing, Reasoning) Protégé Core System Protégé GUI Protégé API (Tabs, Widgets, Menus) (Classes, properties, individuals, etc.) OWL File DB Storage Storage

Protege-OWL API (Model) RDFObject Frame (Protege) RDFSLiteral RDFResource RDFSClass RDFIndividual RDFProperty RDFSNamedClass OWLProperty OWLAnonymousClass ... OWLNamedClass OWLObjectProperty OWLDatatypeProperty

Protege-OWL API Example JenaOWLModel owlModel = ProtegeOWL.createJenaOWLModel(); RDFSNamedClass personClass = owlModel. createRDFSNamedClass ("Person"); RDFProperty ageProperty = owlModel. createRDFProperty ("age"); ageProperty. setRange (owlModel.getXSDint()); ageProperty. setDomain (personClass); RDFIndividual individual = personClass.createRDFIndividual("Holger"); individual. setPropertyValue (ageProperty, new Integer(34));

Java Code Generation RDFIndividual individual = personClass. createRDFIndividual ("Holger"); individual. setPropertyValue (ageProperty, new Integer(34)); Person individual = factory. createPerson ("Holger"); individual. setAge (34);
