Ground-breaking visual RDF/OWL editor



Using this application would be the sensible way to put the Semantic Web to work for you. Altova SemanticWorks 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 makes the job easy with tabs for instances, properties, classes, etc., context-sensitive entry helpers, and automatic format checking.Today, the W3C is looking towards the next evolution in Web technologies: the Semantic Web. In the Semantic Web data itself becomes part of the Web and is able to be processed independently of application, platform, or domain.Where the current Web is a collection of documents, the Semantic Web is more like a huge database, in which data on Web pages as well as in databases and legacy systems can be searched, processed, and acted on by machines in meaningful ways. The Semantic Web relies on structured sets of metadata and inference rules that allow it to “understand” the relationship between different data resources. The technologies that form the basis of the Semantic Web by adding these metadata and inference rules are RDF (Resource Description Framework) and OWL (Web Ontology Language). Here are some key features of "Altova SemanticWorks":

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 GUI 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 document's classes, properties, instances (aka individuals), all-different items, and ontologies can be viewed in separate tabs (screenshot below). These tabs provide an overview of each of these categories. A subsidiary pane displays related information (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 pane.
· Clicking the Detail View button (see Main Window) of an ontology item in the Overview, changes the view to a detailed view of that item's relationships (see screenshot).
· In Detail View, relationships are indicated by a range of intuitive icons which are inserted into the ontology via a context menu.
· Relationships in Detail View can be expanded and collapsed at multiple levels to provide easily customizable views of ontologies or specific parts of ontologies.
· Prefixes of URIrefs used in an ontology can be conveniently set in a special table accessed via the GUI.
· The display of blank nodes (anonymous classes) can be toggled on and off.
· Text View enables direct text editing of the ontology document.

Checking documents:
· An RDF, RDF Schema, OWL Lite, OWL DL, or OWL Full document can be checked for syntax according to the rules of the relevant specification/s. Additionally, OWL Lite and OWL DL documents can be checked for correct semantics (according to the rules of OWL Lite and OWL DL, respectively). Errors are listed in the Errors Window, and each error has one or more links to the incorrect item/s in the current view (Text View or RDF/OWL View) of that document.

Other major features:
· Imports can be reloaded at the click of a button whenever required.
· Ontologies can be saved as .rdf, .rdfs, or .owl files and can be exported in their RDF/XML and N-Triples formats.
· Multiple ontologies can be edited concurrently in multiple windows.
· A large range of customization options enables the application interface to be flexibly customized. Options range from GUI font selection to choosing document encoding.
· The graphical Detail View of ontology items can be printed as well as saved as an image.
