Here are the presentations given by Virgil Green
and Pam Schnebelen at the IUC97, EUC97, and IUC98 conferences. The production of both the
IUC97 and IUC98 CDs had "technical problems" which resulted in versions that
were not usable as intended. This should give you all you need. A copy of the Read Me file
is included below.

This presentation was prepared using Microsoft PowerPoint 97 and Lotus ScreenCam 97. The
Screencam 97 viewer is included. If you don't have PowerPoint 97, you can get the viewer
from the Microsoft PowerPoint
web site.
Before you view these presentations, you must run the ScreenCam viewer once to prepare it
for use on your system. After running it once, it can be invoked automatically by the
running presentation.
The group model provided was built with Obsydian 2.2a. It has since been upgraded to
Obsydian 3.0. You will need to extract your own local model to work with it. All Entities,
diagrams, and functions described in the presentation are included in the model.
