Good Overview The OWL-S Editor is a Tab Widget plugin for Protégé. Users who are familiar with Protégé, especially using the OWL Plugin, should have no problem using the OWL-S plugin. Our tab provides an excellent overview of the main instances of an OWL-S service, providing editing modes for its four main classes--Service, Profile, Process and Grounding. The relations between the different parts of an OWL-S service are shown in an intuitive way in the GUI, and can also be shown as a graph.

Import/Export The OWL plugin normally generates one single OWL file from the Protégé knowledge base, but OWL-S services are typically divided into four files--one for each of the Service, Profile, Process and Grounding instances. There is also the need to edit domain ontologies connected to the OWL-S service. We are working with the Protégé developers at SMI to solve this.

Input/Output/Precondition/Result Manager OWL-S services have inputs, outputs, preconditions and results, and these are typically referenced in several places throughout the service description. Our IOPR Manager makes it easy to handle the sometimes complicated relations between these instances, and to create, edit and delete new inputs, outputs, preconditions and results. The IOPR Manager also performs some consistency checks. For example, having an input in the profile, which does not appear in the corresponding process, is usually an error, and will give a warning.
