How do I load a Protege-OWL ontology from a Protege database using the API?
Method 1
The simplest way to load a Protege-OWL ontology from a Protege database is to programatically load the project file (.pprj), which already contains all of the necessary 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 Protege-OWL database ontology:
JenaKnowledgeBaseFactory.useStandalone = false; Collection errors = new ArrayList(); OwlDatabaseFromFileCreator creator = new OwlDatabaseFromFileCreator(false); creator.setDriver("com.mysql.jdbc.Driver"); creator.setURL("jdbc:mysql://localhost/protege"); creator.setUsername("protege"); creator.setPassword("mypass"); creator.create(errors); OWLModel owlModel = creator.getOWLModel();
