The First Joint Conference of GI and SI will have a major track dedicated
to Oberon. There will be an Oberon tutorial, four talks,
and a plenary discussion. Members of ETH's Oberon team will be present for
personal discussions. Coffee and Gipfeli will be served during the breaks.


The conference language will be German, but the proceedings (to be
published by Springer-Verlag) will contain English versions of the papers.

All this will happen on Monday, September 18th, 1995.

Here are the abstracts of the talks:

The Smart Document or How to Integrate Global Services

Juerg Gutknecht
Institut fuer Computersysteme
ETH Zurich, CH-8092 Zurich
gutknecht@inf.ethz.ch


Driven by a foreseeable significant increase of global services (cable and
wireless) in the near future, client/server environments will
progressively replace systems that operate a single computer or
workstation in isolation. Modern operating systems will not merely be
expected to access but to integrate global services as smoothly as
possible, because it is unreasonable to require users to learn a different
interface for every single service that they want to use. Services should
be presented uniformly and called implicitly, i.e. service-specific
technical details should be handled by the system unconspicuously and
behind the scenes.

We believe that the document-oriented approach is best suited to this
purpose. We present and demonstrate a versatile document-oriented
interface for Oberon that - currently - integrates local documents, visual
objects, symbolic computation servers, Web and Teletext.

Integrating Oberon Resources into the World-Wide Web

Ralph Sommerer
Institut fuer Computersysteme
ETH Zurich, CH-8092 Zurich
sommerer@inf.ethz.ch


The World-Wide Web (WWW) is currently one of the most popular network
information systems on the Internet. The range of items that may be
accessed within the WWW includes hypertext documents, images, sound
patterns and video sequences. To identify these items, their location and
the method to acquire them, a generic naming scheme is provided. Besides
the identification of these items it allows to specify and parametrize
activities that construct items "on-the-fly". Hence, aspects of
interaction may be introduced to the information system.

In our paper we discuss this interactive potential power of the WWW,
especially how to obtain this power from the Oberon operating system. Our
attention is directed to aspects of information provision, i.e. we explore
the suitability of the Oberon system for a WWW information server. The
objective is the integration of interactive Oberon applications and
services in the global WWW document space. Hence, we allow remotely to
invoke Oberon activities which produce textual or graphical data from any
location in the world. The integration is based on a simple server
framework that allows to attach Oberon services to the WWW with minimal
implementation effort.

A Comparison of C++, FORTRAN 90 and Oberon-2 for Scientific Programming

Bernd Moesli
ARITHMETICA
CH-8307 Effretikon, Switzerland
moesli@arithmetica.ch


In the past decade, the programming languages C++, FORTRAN 90 and Oberon-2
all evolved from their ancestors. This invites to reflect upon the
suitability of these modern programming languages for scientific and
engineering computing. In the first part, we compare their primary
language features, as needed by scientists and engineers. In the second
part, we list some useful features missing in Oberon-2. The report
concludes by a personal assessment of the three languages with respect to
the numerical context. The reader's experience in scientific programming
in C or FORTRAN would be advantageous.

Oberon Dialogs: A User Interface for End Users

Markus Knasmueller
Institute for Computer Science (Systemsoftware)
Johannes Kepler Universitaet, Altenbergerstrasse 69, A-4040 Linz
knasmueller@ssw.uni-linz.ac.at


This paper describes the Dialogs package which allows a user to create and
use dialog viewers with buttons, check boxes, text fields and other user
interface elements. Dialogs fit smoothly into the Oberon system. Existing
tools can be equipped with a graphical user interface without
modifications. The object-oriented nature of Dialogs allows adding new
user interface items and new commands even by third party programmers and
end users.
