Note: This User's Guide describes how to use the Protege-Frames interface. If you wish to use the OWL extension to Protege, see the CO-ODE website for documentation and examples.

The Protege-Frames editor enables users to build and populate ontologies that are frame-based, using a knowledge model which is compatible with the Open Knowledge Base Connectivity protocol (OKBC). In this model, an ontology consists of:

• a set of classes, organized in a subsumption hierarchy to represent a domain's salient concepts

• a set of slots, associated to classes to describe their properties and relationships

• a set of instances of those classes - individual exemplars of the concepts that hold specific values for their properties

Features of Protege-Frames include:

• A wide set of user interface elements that can be customized to enable users to model knowledge and enter data in domain-friendly forms.

• A plug-in architecture that can be extended with custom-designed elements, such as:

  • graphical components (e.g., graphs and tables)

  • media (e.g., sound, images, and video)

  • various storage formats (e.g., RDF, XML, HTML, and database back-ends)

• additional support tools (e.g., for ontology management, ontology visualization, inference and reasoning, etc.)

• A Java-based Application Programming Interface (API) that makes it possible for plug-ins and other applications to access, use, and display ontologies created with Protege-Frames.
