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. 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

Jurg Gutknecht
Institut fur 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 fur 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.
