GKB-Editor User Manual

Version 2.1



Invoking the GKB-Editor

This section assumes you have already installed the GKB-Editor at your site, and have successfully loaded the code into a lisp image containing one of the supported frame systems. For a high level description of the GKB-Editor and its capabilities, see the GKB-Editor home page. For installation information, see the Installation Instructions.

To start up the GKB-Editor, type (user:run-gkb-editor) to the lisp listener. A large window will appear containing a copyright notice and divided vertically into five parts:

If, when you start, a KB has already been selected (either because you used the GKB-Editor to select it last time, or because you opened it using the GFP), you may begin browsing the KB immediately. Otherwise, you must open and select a KB before you can begin browsing or editing. If no KB is currently open, you will see the message Create or Open a KB in the status line where you would normally see the name and package of the KB.

The first time you open a KB, you must use the Open or New command, which will pop up a dialogue, prompting you for a filename and other information about the KB. This information is saved persistently, so the next time you wish to open the same KB, you need only select its name from the list of KBs provided when you invoke the Open command. For more information, see the section on Opening a KB.

Types of Viewers

The GKB-Editor features four types of viewers, the class hierarchy viewer, the frame relationships viewer, the spreadsheet viewer, and the frame-editing viewer. The original application window that appears when you first start up the GKB-Editor is the class hierarchy viewer. From this window, you can pop up either of the other three viewers. However, many of the application and knowledge base operations are accessible only from this original application window, so you must eventually return to it. Descriptions and examples of each of the available viewers are given in the appropriate sections. We recommend you read the section on the class hierarchy viewer first, before reading about the other three viewers.
