How to load an ontology from a Prot¨¦g¨¦ OWL Database using the API?     Method 1    The simplest way to load an OWL Database project is to load programmatically the project (pprj file), which already contains all database connection information: Project prj = Project.loadProjectFromFile("/home/pizza_db.pprj",errors); OWLModel owlModel = (OWLModel) prj.getKnowledgeBase(); ... Method 2 The second method should be used if there is no project file (.pprj) associated with the OWL Database ontology.   OWLDatabaseKnowledgeBaseFactory factory = new OWLDatabaseKnowledgeBaseFactory();          Project prj = Project.createNewProject(factory, errors); OWLDatabaseKnowledgeBaseFactory.setSources(prj.getSources(), "com.mysql.jdbc.Driver", "jdbc:mysql://localhost:3306/protege", "pizza", "user", "password"); prj.createDomainKnowledgeBase(factory, errors, true); OWLModel owlModel = (OWLModel) prj.getKnowledgeBase();
