Altova SemanticWorks - Version 2012 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
