Altova’s SemanticWorks is a visual Semantic Web editor that features a graphical RDF and RDFS editor and a graphical OWL editor, supports OWL Lite, OWL Full, and OWL DL dialects. SemanticWorks provide syntax and format checking options and the evaluation of ontology semantics with direct links to errors. It can generate code in RDF/XML and N-Triples, and convert RDF/XML to N-Triples and vice versa. The RDF and OWL diagrams can also be printed. New class instances can be defined using intelligent shortcuts.
