TUTORIAL 1: Object-Oriented Multimedia Technology
Instructor: Max Muehlhaeuser
University of Karlsruhe, Germany
Level: Beginning
Time: Monday, 4 July, 9.00-17.30
WHO SHOULD ATTEND:
The tutorial is intended for researchers and practitioners who
want to gain an overview about multimedia technology -
multimedia/hypermedia software development and distribution in
particular - with a special focus on object-oriented approaches.
ABSTRACT:
The tutorial will provide both a "broad" introduction into
multimedia technology and a more "in-depth" coverage of "object-
oriented" multimedia technology. The attendant will be able to
familiarize with current standards and methods as well as open
issues with respect to both stand-alone and distributed multimedia.
She/He will get an understanding of ways to extend object-oriented
concepts for the support of multimedia. Particular attention will be
paid to issues like distribution, cooperation, OO multimedia
services, hypermedia integration, and emerging OO multimedia
standards and frameworks. Part 1, the "broad" introduction, will
comprise chapters like: "overview and reference architectures",
"interaction and compression", "storage, documents & archives",
"Network and OS support", "synchronization, platforms & services".
Part 2, the OO related part, addresses areas like "multimedia object
models", "OO multimedia programming", "OO and hypermedia",
"distributed multimedia objects", and "towards media-integrated OO
frameworks".
Max Muehlhaeuser received both his Diploma and his Doctorate in
puter Science) from the University of Karlsruhe,
West Germany.
He set up and managed a campus-based research center for Digital
Equipment and worked as a Professor for Computer Science at the

TUTORIAL 2: Testing Object-Oriented Software
Instructor: John D. McGregor
Clemson University and Software Architects, USA
Level: Advanced
Time: Monday, 4 July, 9.00-17.30
WHO SHOULD ATTEND:
The tutorial assumes experience using object technology to
develop software and a typical developer's knowledge about
software testing.
ABSTRACT:
This tutorial has two major goals:
(1) to present techniques for building classes that are testable;
(2) to present a process and techniques for a comprehensive testing
process within a software development project.
The tutorial presents class design guidelines about building "hooks"
that support the testing process, a set of algorithms for
generating test cases, and a case study of a small, but complete,
software system. The case study will relate the various analysis,
design, and implementation work products to the development of test
harnesses, and the management of test cases. The techniques
presented are intended to minimize the number of test cases that
must be built for adequate coverage, to minimize the number of those
test cases that must be executed at any time, and to accommodate
varying test coverage requirements in a consistent manner.
John D. McGregor is an Associate Professor of Computer
Science at Clemson University and a principal partner in Software
Architects, a software design consulting firm, specializing in
object-oriented design techniques. he has made
presentations and presented tutorials on object-oriented

Level: Beginning
Time: Monday, 4 July, 9.00-12.30
WHO SHOULD ATTEND:
Professionals and Researchers with a background
in Object Technology and of classical database technology.
IT managers who wish to evaluate an ODMS.
Knowledge of an object oriented programming language and
conventional database is preferred.
ABSTRACT:
The tutorial is divided in two parts. Part one will offer an
in-depth description of the relevant features of an ODMS (e.g.
query languages, schema evolution, language bindings. versioning,
architecture). The focus is on the database features rather than
the OO features in general. Each feature will be illustrated by
means of examples. Part two will present a framework for classifying
and evaluating the various ODBMS products.
It will also cover standardization activities such as the ODMG-93
specification and its relationships with OMG-standards (i.e. CORBA).
An overview of the market for ODBMSs will also be offered.

TUTORIAL 4: Object Management Systems (OMS)
Instructors: Aleks Gollu, UC Berkeley/Meta-X, USA
Akash Deshpande, UC Berkeley/Amravan, USA
Level: Intermediate
Time: Monday, 4 July, 9.00-17.30
WHO SHOULD ATTEND:
Basic understanding of object oriented methodology and database
concepts and some experience with large scale software application
delivery is helpful.
Project managers and development and research engineers can attend.
ABSTRACT:
Most Large Scale Software Applications use a logical representation
to simulate and control the behavior of a physical system. The range
of these applications is vast: Data Network Management (DNM), Power
Distribution Management, Intelligent Vehicle Highway Systems (IVHS),
and increasingly even Management Information Systems. Such
applications benefit immensely from the Object Mangement System(OMS)
approach. The OMS approach consists of 1) the OMS software platform
and 2) the OMS implementation process. OMS software platform
provides a unifying framework for semantic data modeling, client-
server architectures, concurrent user support, data distribution,
persistent storage, and performance optimization. The OMS
implementation process defines the stages of a project life-cycle
including the key players involved and the time and resource
requirements. We present case studies of completed DNM and IVHS
projects that employed OMS. We discuss the OMS approach using
today's software technologies and identify areas for future
enhancements of the OMS platform based on emerging technologies.
Aleks Gollu and Akash Deshpande each have 10 years of experience in
Large Scale Software Development and Database Management Systems
ranging from system development to project management. They have
worked on such large projects as Concert - British Telecom's
trademark Integrated Network Management System (NMS), Accumaster
Integrator - AT&T's trademark NMS, Megastream - Bell Canada's
flagship NMS, and PATH UC Berkeley and Caltrans' Intelligent Vehicle
Highway System (IVHS).

TUTORIAL 5: Distributed Computing using Objects
Instructor: Eric Jul
University of Copenhagen, Denmark
Level: Intermediate
Time: Monday, 4 July, 9.00-12.30
WHO SHOULD ATTEND:
The tutorial assumes basic knowledge of object-oriented concepts.
Nted computing is required, however,
experience with one or more OO programming languages would be
helpful.
ABSTRACT:
As computer networks become faster and cheaper, it becomes more
and more desirable to use distributed computing.
Object-oriented programming seems to mesh exceptionally well with
the paradigms of distributed programming because of object
encapsulation and the clean interface presented by an object.
The aim of this tutorial is to motivate and demonstrate
the use of objects for distributed computing.
The tutorial will cover the basic ideas and paradigms of
distributed computing including
* communication, RPC
* remote referencing
* parallel processes
* distributed, globally shared objects
* distributed synchronization
* reliability/failure handling
* replicated objects
* persistent objects
* wide area vs. local area networks
* load sharing/load balancing
* examples of distributed programs
* what to look for in a distributed OO language
* overview of available distributed object systems
* short overview of major implementation issues
All major points will be illustrated by examples written
in the distributed, object-oriented language, Emerald;
however, you need no previous knowledge of Emerald.
This tutorial will provide you with a general overview of how and
why to use distribution and objects.
Eric Jul is an Associate Professor at DIKU, the Dept. of Computer
Science, University of Copenhagen where he is the leader of the
DistLab group which is doing research in distributed, heterogeneous
computing.
He is a co-designer and implementor of the Emerald distributed
object-oriented programming language developed at the University of
Washington. His interests include distributed, OO languages,
operating systems support for such languages including distributed
storage management (distributed shared memory and garbage
collection) and object-oriented design and analysis. He has run a
number workshops related to distributed computing at previous
ECOOP/OOPSLA conferences.
TUTORIAL 6: The ANSA Architecture for Distributed Computing
Instructor: Hugh Tonks
Architecture Projects Management Ltd., UK
Level: Intermediate
Time: Monday, 4 July, 14.00-17.30
WHO SHOULD ATTEND:
This is a beginner's guide to distributed systems concepts, but is
also suitable for intermediate or advanced level people in any
computing discipline. It is intended for system integrators,
strategists, designers, programmers, or anyone technical
with an interest in distributed computing, object-based
technology or client/server systems.
ABSTRACT:
The ANSA architecture has been designed primarily to help solve the
twin problem sets of heterogeneous systems and distributed
computing; in particular, it deals with issues of achieving
interoperability between future systems and existing systems. In
doing so, it draws on ideas from a wide range of computing
disciplines, including object orientation, to provide generic
techniques and principles which can be used effectively in the
design and construction of distributed systems.
This tutorial will cover the fundamental principles of ANSA, showing
how they can be applied to real systems development, and how ANSA
relates to other distributed computing initiatives. Specific topics
will include the nature of architecture, the use of client/server
and objects as the basis for building large systems, the application
of tool-based solutions, some concrete examples of how ANSA
principles and concepts can be realised in code, and how the
programmer's view of a distributed system might look in the future.
Objects will be discussed in some detail, not necessarily as a
solution in themselves, but as crucial components of any ANSA-based
approach to systems design and implementation. This tutorial will be
fairly intensive, as it is essential to cover a number of
interrelated concepts in a short time in order to put over the
complete ANSA picture accurately.
Hugh Tonks has been with the ANSA programme for over five years,
both as a member of the research team working on persistence, and
latterly as business manager. Prior to ANSA, after graduating in
Computer Science from Cambridge, he worked for GEC Marconi Research
and Torch Computers, as a consultant to the thoroughbred racehorse
industry, and for the US Department of Customs in Saudi Arabia,
specialising in database applications.
TUTORIAL 7: Models and Paradigms of Interaction
Instructor: Peter Wegner
Brown University, USA
Level: Intermediate
Time: Tuesday, 5 July, 9.00-12.30
WHO SHOULD ATTEND:
Persons interested in the conceptual foundations of object-oriented
programming and in the notion of interaction as a first-class form
of computation.
ABSTRACT:
Our goal is to develop a conceptual framework for object-oriented
programming in terms of models of interaction and component-based
software technology. We will develop a model of component
interaction, showing that models of object-oriented software
engineering such as Rumbaugh's object model and Jacobson's use-case
model are models of interaction rather than computation. Life-cycle
models, open systems, and scalability will be expressed in terms of
models of interaction. Processes, application program interfaces,
frameworks, multidatabases, GUIs, robots, and virtual reality will
be uniformly described as paradigms of interaction. We will show
that object-oriented models of interaction have inherently greater
expressive power than algorithmic models of computation because
they determine a "marriage contract" for interactive services over
time that cannot be expressed by a pattern of time-independent
"sales contracts". This result provides a technical explanation for
the fact that models for programming in the large are based on
software components rather than functional or logic programming
languages. Lecture notes will include a 35-page paper on ``Models
and Paradigms of Interaction'' appearing in the proceedings of last
year's ECOOP workshop on distributed object-oriented programming
(Springer-Verlag Lecture Notes in Computer Science, 1994).
Peter Wegner, a Professor of Computer Science at Brown University,
was educated at London and Cambridge, and taught at Cornell, Penn
State, and the London School of Economics before coming to Brown.
His research interests include programming languages and software
engineering. He has authored or edited a dozen books including the
first book on Ada in 1980, and has edited books on research
directions in software engineering and object-oriented programming.
He has contributed to object-oriented programming in the areas of
type theory, concurrency, and language design issues. He is
interested in component-based software technology and models of
interaction as an integrating framework for object-oriented and
multiparadigm programming.
TUTORIAL 8: Adaptive C++ Software
Instructors: Karl Lieberherr, Cristina Videira Lopes, Walter Huersch
Northeastern University, USA
Level: Intermediate
Time: Tuesday, 5 July, 14.00-17.30
WHO SHOULD ATTEND:
Intermediate level C++ programming. The tutorial is aimed at
software professionals wanting to write C++ programs faster and in a
more reusable form.
ABSTRACT:
As object-oriented projects grow above a few dozen classes, they
tend to hit the small methods productivity wall - the point at which
a large number of small methods exist in the software. The many
small methods make maintenance of the software difficult, especially
when the structure of the objects evolves. This tutorial defines the
problem and presents a practical solution based on adaptive
software. Adaptive software is a high-level description of object-
oriented software and allows to significantly improve the ease of
maintenance of object-oriented software.
Karl J. Lieberherr is a Professor in the College of Computer Science
at Northeastern University in Boston and Director of the Center for
Software Sciences. His current research interests are in object-
orienteeering. His research group is developing the
Demeter System, consisting of the Method and the Tools, to
facilitate software development by introducing novel high-level
abstractions. The most important contribution of the Demeter System
is the concept of adaptive software which generalizes object-
oriented software and which amplifies its advantages while
eliminating some of its disadvantages. He is working on a book on
the Adaptive Software which is published by PWS Publishing Company
together with the Demeter Tools. Karl Lieberherr has given tutorials
before at OOPSLA '91, '92, ECOOP '92, Electro '92, The MIT Summer
School since 1992, National Technological University and at several
companies.

TUTORIAL 9: Object-Oriented Reuse - From Management to Coding
(The REBOOT Approach)
Instructors: Frank Buschmann, Hans Guenter Tempel
Siemens AG, Corporate Research and Development, Germany
Level: Intermediate
Time: Tuesday, 5 July, 9.00-17.30
WHO SHOULD ATTEND:
Managers of software development organizations using object-oriented
technology and of object-oriented projects. Software developers
having a sound knowledge of object-oriented technology. Anyone
interested in reuse using object-oriented techniques.
ABSTRACT:
Reuse is regarded as one of the most promising approaches to master
the challenges of software development. However, although this goal
sounds desirable it is not easy to achieve. This tutorial presents a
sound foundation for object-oriented reuse to succeed as well as to
promote organized reuse. A managerial part is covering
organizational and managerial issues related to software reuse, such
as organizational structures, project management, and library
management. A technical part presents concrete methods, techniques,
and guidelines supporting software development for and with reuse as
well as re-engineering for reuse. The tutorial is based on the
ESPRIT-III project REBOOT (REuse Based on Object-Oriented
Techniques) where the presented approach was developed and
successfully applied for various industrial applications. The
overall goal of the tutorial can be broken down into several
subgoals:
* Providing a sound and complete understanding of the reuse
problem space.
* Providing a guide for how to introduce and continuously measure
and improve the reuse capability of an organization.
* Facilitating the mastery of the techniques needed to organize
and develop for and with reuse.
A real world example is used throughout the tutorial in order to
illustrate and explain the various organizational, managerial,
methodological and technical issues related to software reuse.
Frank Buschmann is Software Engineer at SIEMENS AG, Corporate
Research and Development (Munich, Germany). His work focuses on
object-oriented technology, software reuse and software
architecture. He is a member of the ANSI C++ standards committee and
member of the ESPRIT-III project REBOOT. Results of his work were
presented by him at several conferences on object-oriented
technology.

are in re-engineering, reverse engineering, and software reuse. He
is a member of the ESPRIT-III project REBOOT and he is leading the
re-engineering activities of this project.
TUTORIAL 10: How to Develop Frameworks
Instructor: Ralph E. Johnson
University of Illinois at Urbana-Champaign, USA
Level: Advanced
Time: Tuesday, 5 July, 9.00-12.30
WHO SHOULD ATTEND:
A year or two experience developing object-oriented software.
ABSTRACT:
This tutorial will describe a process for developing frameworks.
The process is driven by examples, which are used both to design
a new framework and to document it when it is finished. A framework
is developed by generalizing and abstracting from examples. The
tutorial will show how standard design transformations are used to
generalize existing systems, making them more reusable and abstract.
It will discuss how to choose examples, how to manage the iteration
that seems to be an inevitable part of framework development, and
the importance of common design patterns that arise as a framework
is being developed (see Tutorial 11 on design patterns).Developing a
framework is expensive, but it is valuable. This tutorial will help
you to estimate the costs involved in developing a framework. It
will frankly discuss problems in paying for framework development,
though unfortunately it does not offer any easy solutions.
For the past 8 years, Prof. Johnson has been studying object-
oriented technology and how it changes the way software is
developed. He has been involved in the development of an object-
oriented operating system (Choices), compiler (Typed Smalltalk),
graphics editor framework (HotDraw), music synthesis system (Kyma),
and is currently working on a framework for accounting. He is on
the faculty of the Department of Computer Science at the University
of Illinois at Urbana-Champaign and has helped organize several
OOPSLA's, including OOPSLA'93 as program chair.
TUTORIAL 11: Design Patterns: Elements of Reusable Object-Oriented
Software
Instructor: Richard Helm, DMR Group, Inc.,Canada
John Vlissides, IBM T. J. Watson Research Center, USA
Level: Advanced
Time: Tuesday, 5 July, 14.00-17.30
WHO SHOULD ATTEND:
Attendees should understand basic object-oriented concepts, like
polymorphism and type versus interface inheritance, and should have
had some experience designing object-oriented systems.
ABSTRACT:
Designing object-oriented software is hard, and designing reusable
object-oriented software is even harder. Experience shows that many
object-oriented systems exhibit recurring structures or "design
patterns" of communicating and collaborating objects that promote
extensibility, flexibility, and reusability. This course describes
a set of fundamental design patterns and, through a design scenario,
demonstrates how to build reusable object-oriented software with
them. Participants will acquire experience in using design patterns
to solve real problems. This experience will enhance participants'
design abilities by teaching them how to apply design patterns to
their own object-oriented systems. The course covers the roles
design patterns play in the object-oriented development process: how
they provide a common vocabulary, reduce system complexity, and how
they act as reusable architectural elements that contribute to an
overall system architecture.
Richard Helm is a Senior Technology Consultant with DMR Group,
an international information technology consulting firm.
There he is actively applying design patterns to the design of
commercial systems. He has numerous international publications
and is a past OOPSLA program committee member. He has a Ph.D. in
Computer Science from the University of Melbourne, Australia.
John Vlissides is a researcher at the IBM T.J. Watson Research
Center. His research interests include object-oriented design tools
and techniques, application frameworks and builders, and program
visualization. Before IBM, he was at the Computer Systems Laboratory
at Stanford University. There he co-developed InterViews, a popular
object-oriented system for developing graphical applications. He
has a Ph.D. in electrical engineering from Stanford University.
mal Methods for Object-Oriented Software
Engineering Methodologies.
Instructor: Mahesh Dodani
University of Iowa, USA
Level: Advanced
Time: Tuesday, 5 July, 9.00-12.30
WHO SHOULD ATTEND:
This tutorial is appropriate for software engineers with some
experience using object-oriented methodologies. A basic knowledge of
logic is assumed.
ABSTRACT
This tutorial views object-oriented software engineering
methodologies as comprising two components: a set of methods to
build the object, dynamic, and functional models of software; and a
process that governs the use of the methods for software
development. The aim of the tutorial is to present the state-of-the-
art in semantically rich object-oriented methodologies. Such
methodologies employ formal methods for the object, dynamic and
functional models of software. These formal methods allow clear,
concise, and unambiguous specifications, and facilitate verification
of correctness, completeness, and consistency. The precise semantics
allow properties of the software to be validated, and consistency
across the models to be established. Realistic case studies are used
to facilitate a deeper understanding of using the methods. A "use-
case" driven process is used to establish consistency across the
models.
Mahesh Dodani is an Assistant Professor of Computer Science at the
University of Iowa where he directs several groups conducting
object- oriented (OO) research. He has been involved in building
many OO systems ranging from interface builders to database design
tools. He has experience with the popular OO software engineering
methodologies (including Booch, OMT, FUSION, and Coad/Yourden), and
semantically rich methods (including COLD, Larch, OBJ3, StateCharts,
and Z). He is the major proponent of instituting a M.S. subtrack
that provides practical and realistic OO software engineering
education and training. He has consulted with several industrial
organizations on OO technologies, and is a regular presenter of
tutorials.
TUTORIAL 13: Objects and Constraint Programming
Instructors: Alan Borning, Gus Lopez
University of Washington, Seattle, Washington, USA
Level: Advanced
Time: Tuesday, 5 July, 14.00-17.30
WHO SHOULD ATTEND:
Knowledge of object-oriented programming, including both general
concepts and knowledge of a specific object-oriented language is
required. Knowing a logic programming language such as Prolog would
be helpful but not essential. We won't assume prior background in
constraint-based systems.
ABSTRACT:
A constraint is a relation that should be satisfied, for example,
that a line remain horizontal, that a resistor in an electrical
circuit simulation obey Ohm's Law, or that the height of a bar in a
bar chart be proportional to some number in an application program.
Constraints have been used in a variety of languages and systems,
particularly in user interface toolkits, in planning and scheduling,
and in simulation. Constraint hierarchies, which consist of both
required and preferential constraints, add additional power to
constraint systems. The tutorial will provide attendees with a
background in the theory of constraints; constraint-based
programming languages, in particular constraint imperative
programming, and constraints and object-oriented languages;
constraint satisfaction algorithms, and using constraints in
applications such as user interfaces. A particular area of emphasis
will be constraints and objects, and in particular the
Kaleidoscope'93 language, an experimental object-oriented constraint
imperative programming language.
Alan Borning is currently a Professor in the Department of Computer
Science and Engineering at the University of Washington, Seattle,
USA. He received a B.A. degree in mathematics from Reed College, and
a M.Sc. and Ph.D. degree from Stanford University. While at
Stanford, he did his dissertation research with Alan Kay and the
Learning Research Group at Xerox Palo Alto Research Center, where he
worked on constraint-based simulation environments. He has been at
the University of Washington since 1980. His current research
primarily concerns constraint-based languages and systems,
particularly as tools for building user interfaces and interactive
graphical simulations. Other research interests include object-
oriented languages and human-computer interaction.
Gus Lopez is a Ph.D. student in the Department of Computer Science
and Engineering at the University of Washington, doing dissertation
research on the design and implementation of constraint imperative
languages. He has a B.S. degree from MIT and an M.S. from Brown
University, both in Computer Science. Prior to coming to UW he also
worked as systems engineer at ATT Bell Laboratories.

former will illustrate the ODP Reference Model, the new
ISO-ITU-TS standard for Open Distributed Processing. The basic
concepts of the general framework for ODP will be dealt with,
including the object-based model and the concept of viewpoints. The
latter part of the tutorial will focus on the current and the
potential future impact of Distributed Object Models, Architectures
and Technologies on the Telecommunication world. This part of the
tutorial will survey the telecommunication standards and
European/worldwide initiatives (RACE Projects, TINA-Consortium)
where object orientation and ODP Reference Model are playing a major
role.

TUTORIAL 15: Visualization of Object-Oriented Systems
Instructors: Chris Laffra, Wim de Pauw
IBM T.J. Watson Research Center, USA
Level: Intermediate
Time: Tuesday, 5 July, 14.00-17.30
WHO SHOULD ATTEND:
Object-oriented (OO) professionals who want to learn about state-of-
the-art techniques and paradigms for visualizing object structures
in executing, complex OO systems to enhance their understanding,
profiling, and debugging.
ABSTRACT:
The course shows how visualization can dramatically increase the
understanding of the behavior of an OO program. Most visualizations
focus on showing "static" structures of OO programs (e.g., class
hierarchies). We will demonstrate how dynamic visualizations of a
C++ or Smalltalk program execution can enhance its understanding and
provide exciting insights by applying cognitive associations.
Visualizations can range from high-level behavior views to more
microscopic views, showing object activity. Performance problems,
misconc that cannot be found that easily before, are
now found, just by watching the visualizations. It will be shown how
visualizations can be used to highlight high level communication
patterns; first emphasizing how classes inter-relate. Then, how
individual instances of these classes communicate. These
communications are shown using different kinds of statistical
instruments and record-and-playback tools. Furthermore, it is shown
how customized visualizations can be generated using specialized,
declarative script languages. All presentations will be done in
parallel with running live demonstrations. Each item that is
introduced will be immediately followed by a short example of how it
works in reality. This enables participants to fully understand and
appreciate the use of visual techniques for understanding and
debugging OO programs.
Wim De Pauw and Chris Laffra are both affiliated with the IBM T.J.
Watson Research Center. Wim is currently working on the Object
Visualizer project, an environment for the visualization of object-
oriented programs. He was speaker at the OOPSLA'93 conference with
the paper "Visualizing the behavior of Object-Oriented Systems", and
will speak at ECOOP'94 with the paper "Modeling Object-Oriented
Program Execution". Chris has developed HotWire, a visual debugger
for C++ and Smalltalk, which he demonstrated at OOPSLA'93, where he
also co-organized a workshop and panel on the subject. HotWire has
also been presented at the 1994 USENIX Technical C++ Conference.

* WORKSHOP DESCRIPTION *
************************
Workshop 1: Patterns
Organizers: Frank Buschmann, Siemens AG
Wolfgang Pree, University of Linz
Time: Monday, July 4, 9.00-17.30
Patterns recently emerged in the OO community as a vehicle to
describe "good" OO-design avoiding the necessity to reveal
implementation details. Patterns identify, name, and abstract a
common structural or behavioural principle by describing its
different parts, their collaboration and responsibilities. A number
of questions has been raised in connection with patterns:
* What are patterns?
* What is their exact purpose?
* How to categorize them?
* What is the appropriate notation for patterns?
* What are their implications to methodology?
This workshop tries to explore some of these issues by presentations
and discussions on:
* Definition and Categorization of patterns
* Phases and activities of software development related to the
use of patterns
* The methodological aspects of using patterns
* A catalogue of patterns
Anyone interested in the workshop is encouraged to submit a position
paper on the subject. For detailed information on the workshop as
well as for guidelines for submissions please contact:

Workshop 2: 4th Workshop for Doctoral Students in Object-Oriented
Systems
Organizers: Arjan Loeffen, University of Utrecht,
Mira Mezini and Thilo Kielmann, University of Siegen
Time: Monday, July 4, 9.00-17.30
This one-day workshop intends to advance the personal and
professional development of about 35 PhD-level students working in
the field of object-oriented systems. The workshop will be an
opportunity for PhD students to meet, to discuss their research, and
to further develop their working skills. The workshop will be
divided into three major parts: mutual introduction, technical
program, and non-technical program. The aim of the technical program
is to exchange ideas on topics selected in advance by the
participants. The non-technical program will be concerned with
conducting and organizing research in our rapidly evolving field.
The discussion of these topics will be supported by a talk of an
experienced researcher in the field (to be named).

Workshop 3: Frameworks for Graphics Editors
Organizers: Ralph Johnson, University of Illinois at
Urbana-Champaign
John Vlissides, IBM T.J. Watson Research Lab
Time: Monday, July 4, 9.00-17.30
Graphics editors are needed for CASE tools, for interfaces to
simulations, for CAD, and for nearly any application that presents
information using pictures. A framework for graphics editors makes
it possible to quickly develop a specialized graphics editor for a
particular application. There are now several different frameworks
for graphics editors. We will compare and contrast the frameworks we
have seen or built, develop a taxonomy for them, determine the main
design issues, and explore the variety of solutions that people have
invented for the various problems that we all encounter. The ideal
participant is responsible for developing a graphics editor
framework, though users of such frameworks are also welcome to
participate. Potential participants should submit a description of
their framework (preferably electronically) to:

Workshop 4: Logical Foundations of Object-Oriented Programming
Organizers: Jean-Marc Andreoli, Rank Xerox Research Center
Vijay Saraswat, Xerox Palo-Alto
Time: Monday, July 4, 9.00-17.30
This workshop aims to establish the state-of-the-art in the use of
logic for/in Object-Oriented Programming particularly in the light
of recent developments in computational use of logic (sub-structural
logics, constraints). The workshop will focus on the usefulness of
logic and constraints for modeling object systems and reasoning
about OO programs (e.g. type- and effect-inferencing techniques), on
integrating and enhancing traditional OOP concepts (e.g.
encapsulation, inheritance, overriding, message passing,
synchronization), and for understanding computational ideas that OOP
has traditionally had difficulty with (e.g. real-time, aggregation,
constraints). Contributions (e-mail submissions preferred) should be
concerned with foundational issues (e.g., use of sub-structural
logics), practice (e.g., real-time systems) and new insights aimed
at enhancing our basic understanding of OOP.

Workshop 5: Economic Impact of Object-Oriented and Reuse Based
Methodologies
Organizer: Giancarlo Succi, University of Genova
Time: Monday, July 4, 9.00-17.30
Object-Orientedness and Reusability have been emerging for the last
few years as two of the hottest research fields in software
engineering, furthermore each of them seems to imply the other.
Several research efforts are ongoing, standards are being defined
and the first commercial products are emerging. However there is a
current debate about the impact of these methodologies on
industries, software houses and research institutes, and about their
real economic advantages. The aim of this is to discuss in an
informal and sincere environment their researches, their experiences
and their plans in these fields. Positive and especially negative
experiences are particularly sought.

Workshop 6: Common Elements for Object-Oriented Programming Systems
Organizer: Kurt Geihs, University of Frankfurt
Time: Tuesday, July 5, 14.00-17.30
Although the object model is widely accepted in many areas of
computer science as a solid base for building information processing
systems, the actual research and development takes place in a rather
isolated fashion. There is little "inter-operability" between
disciplines. This workshop brings together researchers and
developers from different areas of computer science that work on
object systems. The aim of the workshop is to encourage and
facilitate the inter-disciplinary discussion of what is needed as a
common foundation. Attempts have been made to define such common
elements. We need to discuss whether those attempts are sufficient
and what kinds of new requirements are introduced by the rapid
technological progress.

Workshop 7: Use of Object-Oriented Technology for Network Design
and Management
Organizer: Michel Dao, France Telecom
Time: Tuesday, July 5, 9.00-17.30
Telecommunications networks are complex dynamic structures whose
design and management require advanced software development methods
and techniques, very likely to benefit from OO technology. The
purpose of this workshop is therefore to bring together people who
have carried out advanced OO applications in that domain, in order
to have a survey of the existing realisations or experiments, and
try to give an insight into future research. We welcome
contributions concerning any OO topics that are relevant to
networks, including (but not limited to) the following:
* object-based knowledge representation;
* OO recommendations for network management;
* OO analysis, specification and design;
* OO implementation of design algorithms;
* concurrent and/or distributed OO implementations;
* OO and distributed databases;
* OO interactive and graphical interfaces;
* OO simulation.
The workshop is also intended to be a challenge to evaluate the
advantages and disadvantages of OO technology for the areas of
network design and management, and more precisely its ability to
bridge the gap between different activities of a same domain (e.g.
for telecommunications networks: network modeling vs. algorithms
implementation, network design vs. network management, etc.).

Workshop 8: System Implementors' Workshop
Organizers: Peter Dickman, University of Glasgow
Eric Jul, University of Copenhagen
Time: Tuesday, July 5, 9.00-17.30
This workshop will bring together those who have previously built,
or are currently implementing, an object support system. This may be
an operating system designed to support objects, the run-time system
for an OO language, a distributed object-support layer or any
similar entity. The systems may be commercial or research platforms,
but should not be purely paper designs. The aim is to provide a
forum in which trade-offs and significant problems can be discussed
by those with practical experience in the area. Potential attendees
will be asked to submit (by 30/4/94) a two page position statement
presenting one issue, problem, or solution, which they wish to
discuss. Each session will address a single topic raised by the
participants and the bulk of the available time will be spent in
structured discussions. For further information (including a more

Worknd Languages for Coordination of Parallelism and
Distribution
Organizers: Paolo Ciancarini, University of Bologna
Oscar Nierstrasz, University of Geneva
Akinori Yonezawa, University of Tokyo
Time: Tuesday, July 5, 9.00-17.30
A new class of models, formalisms, and mechanisms for describing
concurrent and distributed computations has emerged in the past few
years. Some significant representatives in this new class are Gamma,
Linda, Swarm, Linear Objects, ACL, PoliS, and ActorSpaces. All these
models and languages share a few basic concepts: simple features for
describing data and a small number of mechanisms for coordinating
the work of agents in a distributed/parallel setting. Integrating
such features with those offered by concurrent OOP may lead to a
significant step ahead in the state-of-the-art of language support
for distribution and parallelism. The intent of this workshop is to
bring together people interested in coordination language design,
abstract models for coordination, and coordination mechanisms for
distributed operating systems, and who are engaged in or interested
in related research. Deadline for submission of papers: May 2.

Workshop 10: Artificial Intelligence for Object-Oriented Software
Engineering
Organizer: Hermann Kaindl, Siemens Austria
Dennis de Champeaux, Rational
Albert Shappert, Siemens AG
Time: Tuesday, July 5, 9.00-17.30
AI has contributed to OO. For example, frames for knowledge
representation have contributed to the object notion. Moreover,
software engineering has been an enduring interest in the AI
community. Therefore, the application of AI technology especially to
OO software engineering is very promising. This workshop shall
provide a forum to discuss open questions, to present work done, and
to establish future collaborations and mutual insemination of AI
techniques and OO software development. Its objective is to foster
impact from AI onto OO software engineering. Every useful
contribution to apply AI technology to object-oriented software
engineering is welcome.

* ECOOP'94 TECHNICAL PROGRAM *
********************************
The past ten years have seen object-oriented technology make a major
impact on the software industry; it is not going too far to say that
nowadays the notion of object-orientation is revolutionizing all
aspects of the software lifecycle. Success on the practical side has
gone in parallel with continuous scientific growth, so that the
field, far from having settled into quiescence, is still
characterized by a tumultuous vitality of novel directions and
developments. The technical programme of ECOOP'94 testifies this
well, with 25 papers, selected from 161 which were submitted,
covering as wide a range of topics as programming language issues,
databases, analysis, design and reuse, both in the form of research
contributions and of experience reports. Invited talks and panels
provide further insight into the state of the art of OO technology,
by pointing the way to future evolutions and by allowing cross-
fertilization of ideas with related disciplines.

ECOOP'94 Panels
--------------
At this year conference we will have two panel discussions.
The first (Distributed Object-Oriented Applications: Academic vs.
Industry Solutions) will try to contrast two approaches to
distributed Object-Oriented applications: the "academic" way of
using distributed OO languages, characterized by (more or less)
homogeneity, object mobility, and a single distributed workspace,
and the emerging "industrial" solution with much more coarse-grained
objects but (kind of) openness and heterogeneity.
The second panel (Open Implementation: are Black Boxes Dead?) will
debate on the proposition that black-box abstraction (implementation
hiding) itself is at the root of many of the complexity problems we
see in todays applications. It should (and is) being replaced by a
model in which systems allow clients principled control over their
implementation. It is claimed that OO would play a chief role in
achieving such 'disciplined openness' (e.g., the CLOS Metaobject
Protocol), but on the other hand there are claims that OO 'as is' is
still insufficient and refinements as well as enhancements are
required. The panel investigates whether 'Open Implementation' is
really the way of the future as well as how OO should interplay with
the paradigm.

BEYOND OBJECTS
Luc Steels
VUB AI Lab.
Brussels, Belgium.
The paper reports on progress towards reusability and the
configuration of applications by (non-)programmers. The key idea is
to go beyond the level of code, even if it is object-oriented, and
introduce a still higher level of abstraction which balances three
perspectives: tasks, objects, and methods. We have developed a
formal descriptive framework for this level based on feature
structures, and have shown how code can be automatically generated.
We have also demonstrated already the feasibility of isolating
fragments (consisting of code + its formal description)which can
then be incorporated in new applications by cut and paste
operations. Some scenarios of application configuration and
reusability illustrate the paper. The role of reflection and meta-
level architectures will be emphasised.
Luc Steels studied Computer Science and Artificial Intelligence at
MIT and Languages and Philosophy at the University of Antwerp. He is
currently Professor of Computer Science and director of the
Artificial Intelligence Laboratory of the University of Brussels
(VUB). Steels has been active in natural language processing,
knowledge representation, object-oriented programming, knowledge
engineering, and robotics. His recent research focuses on the use of
notions of complexity (self-organisation, chaotic dynamics, emergent
functionality) for the design of autonomous robotic agents. Most
relevant for the object-oriented programming community is the work
with his team at the VUB on a framework for the reuse of information
and knowledge and the configuration of applications by non-
programmers. This research has lead to the KREST workbench which has
a growing user community throughout Europe.
PUTTING OBJECTS TO WORK:
HYPERMEDIA AS THE SUBJECT MATTER AND THE MEDIUM
FOR COMPUTER-SUPPORTED COOPERATIVE WORK
Norbert A. Streitz
Integrated Publication and Information Systems Institute (IPSI)
National Research Center for Computer Science (GMD)
Darmstadt, Germany
One can observe the following parallel developments: an increasing
merge of computer, network and telecommunication technology, new
needs and markets in the information and media industry, indications
of changes in the way people use information in their work and in
their home environments. A common factor is the digitalization of
information at the time it is processed or even better when it is
created. But the progress in networks and basic technology is not
paralleled to the same degree by advances in the development of
corresponding applications which - in the end - are necessary to
justify the immense investments, e.g. in information super highways.
One important class of applications is the area of supporting
synchronous and asynchronous cooperation of spatially distributed
people working with information objects which can be shared in
various ways. This results in tele-cooperation complemented by
audio/video communication channels providing telepresence. We
propose that "hypermedia" serve not only as the "subject matter" of
cooperation, e.g. planning, editing, and reviewing a hypermedia
document, but also a "medium" for coordination, communication, and
cooperation by using specific object types and exploiting their
properties. Hypermedia can be considered as "networked multimedia
documents" in the sense that they represent networks of information
objects (typed nodes and links with multimedia content) but also in
the sense that the information objects are geographically
distributed over a physical network in many locations. In order to
provide examples of how one can support telecooperation, we will
present the design and implementation of two group aware
applications which were developed using an object-oriented approach:
SEPIA - a cooperative hypermedia authoring environment for remote
collaboration, and DOLPHIN - an electronic meeting room support
system using an interactive electronic whiteboard being networked
with local notebook computers and remote desk top workstations.
Norbert A. Streitz is the Deputy Director of GMD-IPSI of the German
National Research Center for Computer Science. At IPSI, he is also
the manager of the research division "Cooperative Hypermedia
Systems". He is an associate editor of the ACM Transactions on
Information Systems (TOIS) and was the Vice Chair (Europe) of ACM
SIGLINK from 1991-1993. He has been a program committee chair and
member of national and international conferences in the areas of
hypermedia, computer-supported cooperative work, human-computer
interaction, systems design, knowledge representation. He is
lecturing in these areas at the Technical University of Darmstadt,
at tutorials connected to conferences and in seminars for industry.

* GENERAL INFORMATION *
***********************
Location
--------
ECOOP 94 main conference (together with exhibition and
demonstrations) will be held from July 6 to July 8 at "Palazzo
della Cultura e dei Congressi" (Piazza della Costituzione 5/C),
while workshops and tutorials from July 4 to July 5 at the Faculty
of Engineering of the University of Bologna (Viale Risorgimento 2).
Situated on the southern edge of the "Pianura Padana", on the lower
slopes of the Apennine foothills, Bologna, the chief town of Emilia-
Romagna, is a city of many faces: its numerous medieval towers, its
churches, its long arcaded streets lined by sumptuous 14C to 17C
palaces recall the former political and cultural importance of
this once independent city. Bologna is famous for its University,
the oldest in the western world, which already numbered 10000
students in the 13th Century. In addition to being an Italian
gastronomic centre, Bologna is an important industrial and
commercial town well-placed on both the national rail and road
networks. The city hosts numerous international fairs, shows and
exhibitions.
Climate
-------
During July the climate is hot. The temperature is between 25 and 30
centigrade degrees and the weather is generally sunny.
Travel to Bologna
-----------------
Bologna can be reached directly by plane from Barcelona, Brussels,
Frankfurt, London, Munich, Nice, Paris, Rome and Milan. Its airport
is 6 km north-west of the city centre, and can be easily reached
in 20 minutes by bus (about 1300 ITL) or in 10 minutes by taxi
(about 20000 ITL).
Bologna is the most important railway centre in Italy: the main
cities of Europe are directly connected with Bologna. If you arrive
by plane at Milan or Rome, the train schedule between these cities
and Bologna is very dense (about a train every hour). It takes
about 3.30h from Rome and 2h from Milan. The railway station is
very close to the center of the city, and can be reached in 10
minutes on foot or in few minutes by bus.
If you plan to arrive to Bologna by car, the city lies next to A-1
(Milan- Bologna), A-13 (Bologna-Padova) and A-22 (Modena-Brennero)
motorways.
Many car rental companies are present both at the airport and at the
railway station.
Transportation in Bologna
-------------------------
A shuttle bus will be arranged to transport the participants of the
conference to and from the major conference hotels.
Reception and Banquet
----------------------
A welcome party will take place on July 6, from 18.30 to 19.30 at
the Palazzina della Viola, in the heart of the old university

together. The party is open for all registered conference
delegates and accompanying persons.
The conference banquet will be held on July 7, 19.30 - 22.00, at the
Villa San Martino, a charming 18th Century building, where you will
