The Demeter Seminar meets in the Fall quarter from 3-5 on Monday
afternoon in 206 Egan Center.

For more info: 
http://www.ccs.neu.edu/research/demeter/seminar/
seminar.txt contains information for the current quarter.

The seminar is suitable for students who have taken COM3360
or have taken Linda Seiter's class on OO design and have read or are reading
my book on Adaptive Programming.

The seminar is also suitable for advanced software developers in industry
or academia who have read some of our papers/book on Adaptive Programming.
(See http://www.ccs.neu.edu/research/demeter)
Depending on the interests of the industrial participants we will
add a specific technology transfer component to the seminar.

============================================================

There is no Demeter Seminar April 14 and 21.

A progress report on the Demeter Project is available from:

April 28:

Johan Ovlinger on TAO

Johan has added traversals as objects to Demeter/Java.
You can now compute traversal strategies under program control.
The benefit: more flexibility when you need it; the price:
less efficient program execution.

Updates on other projects. 

Planned talks May 5:

Karl Lieberherr on "What is an aspect"

While I was at Xerox PARC we had some interesting discussions 
of aspects. We would like to separate aspects from other software
structuring mechanisms and this turns out not to be easy.

Karl Lieberherr on "GenVoca"

The work of Don Batory on software composition is useful for
composing programs. We will discuss an application to Demeter/Java
to solve the repetition class implementation selection problem.

April 7, 1997

Geoff Hulten, Doug Orleans, Johan Ovlinger, Karl Lieberherr

Adaptive Programming in-the-large

We are making very good progress towards a module system for AP,
initiated by Geoff Hulten. We will fill in the rest of the seminar
on our progress.

Planned talks:

==================
Boaz Patt-Shamir: Traversal strategies and their compilation

Boaz will present the generalization of the compilation
algorithm which he presented earlier to forests instead of
linear lists.

===================
Lars Hansen on aspect-oriented exception handling
and around methods

Lars has added around methods to Demeter/Java as a first 
step to dealing with exceptions as an aspect.
===================

Binoy Samuel:
Software architectures
====================================

Kedar Patankar and Binoy Samuel:
AP Studio: A graphical user interface for AP

Kedar and Binoy develop a powerful GUI for AP.
============================================================
The Demeter Seminar has the following purposes:

1. To disseminate information about useful ideas for developing
   flexible software.

2. To discuss ongoing work related to the interests of 
   seminar participants. Currently, a project called:
   Simplifying Software Evolution through Adaptive Programming
   within a larger project called: Evolutionary Design
   of Complex Systems receives a lot of attention.  
   Currently five faculty members, Linda Seiter (Boston College),
   Karl Lieberherr, Jens Palsberg (Purdue University),
   Boaz Patt-Shamir and Mitchell Wand are affiliated with the
   project.

3. To create a nurturing environment for software engineering/
   programming language research. The 
   seminar helped to develop  ideas like
   the Law of Demeter, succinct traversal specs, and adaptive programming
   with context objects.

During some weeks we might not meet. Also watch the Programming Language
Seminar (Professors Wand and Clinger) and the Distributed Systems
Seminar (Professors Cooperman, Matta and Patt-Shamir) for topics
of interest to the Demeter seminar participants.
