Elmo is Java library for Semantic Web applications. Elmo allows developers to create applications that work with RDF/OWL knowledgebases at the level of ontologies instead of working with RDF triples. Elmo's provides a static typed interface to RDF properties within an RDF store. For example, the following code accesses FOAF properties from the RDF/XML file "foaf.rdf" and prints them to standard out. ElmoModule module = new ElmoModule(); SesameManagerFactory factory = new SesameManagerFactory(module); SesameManager manager = factory.createElmoManager(); File file = new File("foaf.rdf"); manager.getConnection().add(file, "", RDFFormat.RDFXML); for (Person person : manager.findAll(Person.class)) { System.out.print("Name: "); System.out.print(person.getFoafNames()); } With Elmo's role based interface and component oriented design, software becomes more flexible and allows for novel opportunities for developing and modularizing domain driven designs. The domain model is simplified into independent concerns that are mixed together for multi-dimensional, inter-operating, or integrated applications.
