A system with an Adaptive Object-Model (AOM) has an explicit object model that it interprets at run-time. If you change the object model, the system changes its behavior. For example, a lot of workflow systems have an Adaptive Object-Model. Objects have states and respond to events by changing state. The Adaptive Object-Model defines the objects, their states, the events, and the conditions under which an object changes state.
There
are various techniques that share common features with AOM's. Especially, those
that try also to capture business rules and build domain specific languages,
namely – Grammar-oriented Object Design (applied in the three major areas of
configurable workflow, tier-to-tier mapping and object graph traversal) or –
Meta-CASE tools and environments approaches, à la MetaEdit+ or à la MétaGen (applied
in various fields of information system modeling: telecom, finance, medicine,
etc.). There are other techniques which also describe ways to build systems
that change behavior at runtime, namely – Reflection at the language level
(mostly applied to programming language design). What is actually common to
those various techniques is that they are leading to, or are driven by,
metamodeling principles and implementation using OO languages.
This
workshop will focus on identifying, cataloging and comparing these techniques
one towards another. We will also try to establish the conditions of use of
these techniques, look at where they meet or overlap, and hopefully set some
cross-fertilization ideas of benefit for each technique.
Adaptive
Object-Models and other techniques such as Grammar-oriented Object Design,
meta-CASE environment approaches or Reflection at the language level, address
at least one of the two following problems:
-
Capturing
[business] rules for user modeling and/or building [Domain] Specific Languages;
-
Building
systems that need to change requirements and reflect those requirements as
quickly as possible, i.e. runtime or dynamic adaptability;
What
is generally common to these techniques is that they actually implement or use
metamodeling principles through OO languages capabilities.
This
workshop will focus on identifying, cataloging and comparing these techniques
one towards another, and other similar ones that share common goals. We will
also try to establish the conditions of use of these techniques, look at where
they meet or overlap, and hopefully set some cross-fertilization ideas of
benefit for each technique.
Workshop
position papers should be 3-10 pages in length and should address one or more
of the following:
-
Examples
of the different techniques
-
Concrete
development reports with lessons learned from them
-
Prerequisites
or needs for each technique
-
Pros
and Cons of the different techniques
-
Comparison
of the different techniques showing overlapping and non-overlapping areas

Nicolas Revault
PhD
from University of Paris 6 (Université
Pierre et Marie Curie), Nicolas Revault is an assistant professor since
1998 at University of Cergy-Pontoise (near Paris). He's attached at the Théma
lab (an associated unit of CNRS) and he's teaching at both departments of
economics & management and computer science of the university. He's also an
affiliated member of the CS lab of university of Paris 6 (LIP6), where he's
working in collaboration with the members of its OASIS team (http://www-poleia.lip6.fr/OASIS/eng_index.html).
From
1991 to 1995, at Lip6 (formerly Laforia lab), he has been the project leader
for the development the first version of the MétaGen tool, a meta-CASE
environment written in Smalltalk (http://www-poleia.lip6.fr/~revault/mg/publications.html).
From a rapid prototyping environment with metamodeling facilities he had been
working on in 1991, he has established the distinction between User
Metamodeling and Implementor Metamodeling promoted by the MétaGen approach. He
has illustrated it through various examples, especially using OO frameworks
through metamodeling (see his PhD thesis). Since then, after three positions of
assistant professor at university of Paris 13, at university of Paris 12 and at
École des Mines de Nantes, he has
been working on various other projects on metamodeling and on model
transformation. He is currently working on adapting these projects to the
recently appeared metamodeling standards (OMG's MOF); he is actually
considering the way of "putting the MOF to work" with existing
[meta-]CASE tools.
He
has been using OO languages and techniques since 1988 (C++, Smalltalk, Java),
and teaching them since 1991, especially with the Smalltalk language (the
various dialects) and more recently… Java.
Joseph W. Yoder
Joseph W. Yoder has worked on the architecture, design, and implementation of various software projects dating back to 1985. These projects have incorporated many technologies and range from stand-alone to client-server applications, multi-tiered, databases, object-oriented, frameworks, human-computer interaction, collaborative environments, and domain-specific visual-languages. Joe has primarily worked with objects since the early 90’s.
Over
the last few years, he has taught Object-Oriented concepts including Patterns
and Smalltalk to Caterpillar and the Illinois Department of Public Health
(IDPH) analysts and developers, and has mentored many developers on the
development applications being deployed across the state of Illinois such as
the Newborn Screening application, the Refugee System, and the Food Drug and
Dairy application. His work with these systems was spawned from his involvement
in the development of an Enterprise Class Library to assist with the ongoing
development of needed IDPH applications. This Enterprise Class Library is a
collection of frameworks and resuable components used for more quickly building
applications at IDPH.
Joe's
recent research has focused on the building adaptable systems; systems that can
quickly adapt to meet the changing requirements of businesses without a huge
programming efforts. Joe is the author of over two-dozen published patterns and
has been working with patterns for a long time, writing his first pattern paper
in 1995, and chaired the PLoP'97 conference on software patterns (http://jerry.cs.uiuc.edu/~plop). Joe is
also one of the original members of the Ralph Johnson's Software Architect
Group at the University of Illinois and collaborated with five of the original
members to form The Refactory, Inc. (http://www.refactory.com).
Joe
enjoys building elegant and successful systems, helping people succeed, and
learning new things. He wants to continue to provide analysis, design, and
mentoring and to write papers that reflect these experiences.

audiences in industry and academia.
Building a Completely Adaptable Reflective
System
F. Ortín Soler and J. M. Cueva Lovelle
Reflection is one of the main techniques used
to develop adaptable systems and, currently, different kinds of reflective
systems exist. Compile-time re-flection systems provide the ability to
customize their language but they are not adaptable at runtime. On the other
hand, runtime reflection systems define meta-object protocols to customize the
system semantics at runtime. However, these meta-object protocols restrict the
way a system may be adapted before its execu-tion, and they do not permit the
customization of its language.
Our system implements a non-restrictive
reflection mechanism over a virtual ma-chine, in which every feature may be
adapted at runtime. No meta-object protocol is used and, therefore, it is not
needed to specify previously what may be reflected. With our reflective system,
the programming language may be also customized at runtime.
Metamodel Composition in the Generic Modeling
Environment
A. Ledeczi, P. Volgyesi and G. Karsai
This paper introduces a CDSDE, the Generic
Modeling Environment (GME 2000), developed at the Institute for Software
Integrated Systems at Vanderbilt University. GME 2000 utilizes metamodeling to
define the domain modeling language along with model integrity constraints and
it automatically configures itself to support the new language. The
metamodeling capabilities of GME 2000, especially its support for metamodel
composition, are in the focus of this paper.

Model-Driven Architecture: Vision, Standards
And Emerging Technologies
J. D. Poole
This paper surveys the core OMG MDA standards
(i.e., UML, MOF, XMI and CWM) and discusses the current attempts at mapping
these standards to J2EE, as examples of
PIM-to-PSM translations that are currently under development. These
forthcoming APIs will provide the initial building blocks for a new generation
of systems based on the model-driven architecture concept. The progression of
these initial MDA realizations to AOMs is the next logical step in this
evolution.
The Architectural Style of Adaptive
Object-Models
J. Yoder, F. Balaguer and R. Johnson
Many object-oriented information systems share
an architectural style that emphasizes flexibility and dynamically
configurable. Business rules are stored in a database instead of in code. The
object model that the user cares about is part of the database, and the object
model of the code is just an interpreter of the users’ object model. We call
these systems “Adaptive Object-Models”, because the users’ object model is
interpreted at runtime and can be changed with immediate (but controlled)
effects on the system interpreting it.
