源代码锻造 (http://owlapi.sourceforge.net/( 中的 OWL API 具有所有基本功能，下面是一个使用 OWL API 库解析 OWL 本体的示例

import static org.semanticweb.owlapi.search.Searcher.annotations;

public class OwlParser {
    private final OWLOntology ontology;
    private OWLDataFactory df;
    public OwlParser(OWLOntology ontology, OWLDataFactory df) {
        this.ontology = ontology;
        this.df = df;
    }
    public void parseOntology()
            throws OWLOntologyCreationException {
        for (OWLClass cls : ontology.getClassesInSignature()) {
            String id = cls.getIRI().toString();
            String label = get(cls, RDFS_LABEL.toString()).get(0);
            System.out.println(label + " [" + id + "]");
        }
    }
    private List<String> get(OWLClass clazz, String property) {
        List<String> ret = new ArrayList<>();
        final OWLAnnotationProperty owlProperty = df
                .getOWLAnnotationProperty(IRI.create(property));
        for (OWLOntology o : ontology.getImportsClosure()) {
            for (OWLAnnotation annotation : annotations(
                    o.getAnnotationAssertionAxioms(clazz.getIRI()), owlProperty)) {
                if (annotation.getValue() instanceof OWLLiteral) {
                    OWLLiteral val = (OWLLiteral) annotation.getValue();
                    ret.add(val.getLiteral());
                }
            }
        }
        return ret;
    }
    public static void main(String[] args) throws OWLException,
            InstantiationException, IllegalAccessException,
            ClassNotFoundException {
        String x = "http://ontology.neuinfo.org/NIF/Dysfunction/NIF-Dysfunction.owl";
        IRI documentIRI = IRI.create(x);
        OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
        OWLOntology ontology = manager
                .loadOntologyFromOntologyDocument(documentIRI);
        OwlParser parser = new OwlParser(ontology, manager.getOWLDataFactory());
        parser.parseOntology();
    }
