Introduction Product Features 9 3.1 Product features The main features of semanticWorks 2007 are listed below Editing RDF documents In SemanticWorks, RDF documents can be created and edited graphically in SemanticWorks's RDF/OWL View. An RDF resource is defined by graphically associating it with a predicate, and then associating the predicate with a resource object or literal value Resources are made available for selection in the GUl by referencing an ontology. A mechanism for declaring namespaces and prefixes enables URIrefs for RDF resources to be assigned flexibly and accurately. SemanticWorks also checks the syntax of RDF documents. Alternatively to editing RDF documents in the graphical RDF/OWL view, RDF documents can be edited directly in Text View, using either RDF/XML notation or N-Triples notation Editing ontologies SemanticWorks offers ontology editing capability in a graphical user interface and in a text interface The graphical RDF/OWL View enables you to easily create and edit RDF Schema and OWL ontologies by allowing you to insert items into a graphical representation of the ontology The ontology level can be changed at any time while editing, enabling you to change levels according to editing needs Syntax checks can be carried out for RDF Schema, OWL Lite, OWL DL, and OWL Full ontologies. Semantics checks can be carried out on OWL Lite and OWL DL documents. These checks can be made while you edit, thus enabling you to easily maintain the validity of the ontology as you build it The ontology documents classes, properties, instances(aka individuals), all-different provide an overview of each of these categories. a subsidiary pane displays relate u items, and ontologies can be viewed in separate tabs(screenshot below).

For example, selecting a class in the Classes Overview causes the instances and properties of that class to be displayed in the subsidiary C 2007 A/tova gmb Works 20© 2007 Altova GmbH Introduction Product Features 9 Altova SemanticWorks 2007 3.1 Product Features The main features of SemanticWorks 2007 are listed below.
