Altova SemanticWorks 2007 is the ground-breaking visual RDF/OWL editor from the creators of XMLSpy. Visually design Semantic Web instance documents, vocabularies, and ontologies then output them in either RDF/XML or N-triples formats. SemanticWorks streamlines the job with tabs for classes, properties, instances, etc., context-sensitive entry helpers, and automatic format checking. It is the sensible way to put the Semantic Web to work for you.
