Altova SemanticWorks 2012 is the ground-breaking
visual RDF/OWL editor for the Semantic Web from the
creators of XMLSpy. Graphically design and edit RDF
instance documents, RDF Schema (RDFS) vocabularies,
and OWL ontologies then output the format of your
choice. SemanticWorks streamlines the job with full
syntax and semantics checking. Additionally, context-
sensitive entry helpers present you with a list of
permitted choices based on the RDF or OWL dialect you
are using, so you're sure to create valid documents
every time. Supported dialects include RDF, RDF
Schema, OWL Lite, OWL DL, and OWL Full. Tabs for
classes, properties, instances, allDifferent, and
ontologies let you focus in on pertinent parts of your
designs. A handy Details entry helper window allows
you to create new instances of RDFS or OWL classes and
assign their properties quickly and easily. As you're
designing, you can switch from the graphical RDF or
OWL view to the text view to see how your document is
being created in either RDF/XML or N-triples format,
and you can export your file from RDF/XML to N-triples
