This file stores a specialisation hierarchy of concepts used in KADS-I methodology. This ontology specialises our top-level ontology of concept types and relations types. If you have a Javascript-enabled Netscape browser, you might be able to use this hierarchy browser (which unfortunately pushes Javascript to its limits of window handling and portability) to visualize and navigate the ontology in textual form below.

You may save this file on your local disk ("File - Save As" command on Netscape) and
then modify this ontology for your needs.
