Release Notes

Installation

• Linux and Solaris installation is now more reliable.
• JDK 1.3 is included in the "with VM" versions of all downloads.
• Mac OS X is now partially supported. The installation appears to work fine but the resulting application cannot be started by double-clicking. It must then be started from the unix command line. We hope that this problem will be addressed shortly by the company providing the installation software. When it is we will update the release.

User Interface

• You can now create annotations which are attached to a frame. You create an annotation by clicking on the yellow "C" button at the top of each form. Annotations are displayed as "yellow stickies" on the form. They can be used to capture design information or just to make notes about a frame for future reference.
• The customization of a form for a class is now inherited by the form for each subclass.
• You can now create and override your own facets on a slot. You do this by adding a template slot to a subclass of :STANDARD-SLOT.
• We have updated the RDF backend so that it supports all the new features. In addition, you can now save PAL constraints with this backend.
• There is a custom editor for entering PAL constraints. It provides assistance with PAL syntax and information on available predicates, functions, and their arguments.
• The system can now automatically record such things as author and creation/modification times for frames and slot values. This recording can be enabled for the instances of a class by attaching one or more of the slots :CREATOR, :CREATION-DATE, :MODIFIER, :MODIFICATION-DATE to the class.

Programmer Interface

• We changed the implementation of a number of widgets and components to make them easier to modify and extend
• We instrumented the knowledge base API to check the arguments for all methods before performing any action. This should make it easier to debug protege plugins. Method calls with invalid parameters now throw exceptions.
