Class OWLXMLWriter

java.lang.Object
org.semanticweb.owlapi.owlxml.renderer.OWLXMLWriter
public class OWLXMLWriter extends Object
Writes OWL/XML. In an OWL/XML documents written by this writer, the base is always the ontology URI, and the default namespace is always the OWL namespace (http://www.w3.org/2002/07/owl#). Unlike RDF/XML, entity URIs aren't abbreviated using the XML namespace mechanism, instead they are encoded using 'prefix' elements.
