This workshop reader, in a way, presents the width of the ongoing research activities in object-orientation. However, we feel one can classify these activities into three cate- ries: • Domain-speci?c: Several activities focus on a single application, e.g. telec- munication, or computer-science, e.g. real-time and mobility, domain. Research tries to address the domain-speci?c problems of object-oriented technology. • Design issues: Object-oriented design has been an issue for at least a decade, but one can identify an increasing focus on formal approaches and on the evo- tion and re-engineering of existing object-oriented software. • Beyond object-orientation: The object-oriented paradigm will, at some point, be replaced by a subsequent paradigm and several research efforts investigate alternative or extended approaches. Examples are extended language expr- siveness for, e.g. design patterns and frameworks, component-oriented p- gramming and aspect-oriented programming. 2 Contents The remainder of this book is a selection and re-iteration of the contributions to 12 workshops (of a total of 15) held during the ECOOP’97 conference. The workshops generally relate to one of the above categories.

This book constitutes the joint refereed post-conference proceedings of 12 workshops held in conjunction with the 11th European Conference on Object-Oriented Programming, ECOOP '97, in Jyvskyl, Finland, in June 1997. The volume presents close to 100 revised selected contributions, including surveys by the respective workshop organizers. The wealth of up-to-date information provided spans the whole spectrum of Object Technologies, from theoretical and foundational issues to applications in a variety of domains.

At the time of writing (mid-October 1998) we can look back at what has been a very successful ECOOP’98. Despite the time of the year – in the middle of what is traditionally regarded as a holiday period – ECOOP'98 was a record breaker in terms of number of participants. Over 700 persons found their way to the campus of the Brussels Free University to participate in a wide range of activities. This 3rd ECOOP workshop reader reports on many of these activities. It contains a careful selection of the input and a cautious summary of the outcome for the numerous discussions that happened during the workshops, demonstrations and posters. As such, this book serves as an excellent snapshot of the state of the art in the field of object oriented programming. About the diversity of the submissions A workshop reader is, by its very nature, quite diverse in the topics covered as well as in the form of its contributions. This reader is not an exception to this rule: as editors we have given the respective organizers much freedom in their choice of presentation because we feel form follows content. This explains the diversity in the types of reports as well as in their lay out.

This volume represents the seventh edition of the ECOOP Workshop Reader, a compendiumofworkshopreportsfromthe17thEuropeanConferenceonObject- Oriented Programming (ECOOP 2003), held in Darmstadt, Germany, during July 21–25, 2003. The workshops were held during the ?rst two days of the conference. They cover a wide range of interesting and innovative topics in object-oriented te- nology and o?ered the participants an opportunity for interaction and lively discussion. Twenty-one workshops were selected from a total of 24 submissions based on their scienti?c merit, the actuality of the topic, and their potential for a lively interaction. Unfortunately, one workshop had to be cancelled. Special thanks are due to the workshop organizers who recorded and s- marized the discussions. We would also like to thank all the participants for their presentations and lively contributions to the discussion: they made this volume possible. Last, but not least, we wish to express our appreciation to the members of the organizing committee who put in countless hours setting up and coordinating the workshops. We hope that this snapshot of current object-oriented technology will prove stimulating to you. October 2003 Frank Buschmann Alejandro Buchmann Mariano Cilia Organization ECOOP 2003 was organized by the Software Technology Group, Department of Computer Science, Darmstadt University of Technology under the auspices of AITO (Association Internationale pour les Technologies Objets) in cooperation with ACM SIGPLAN. The proceedings of the main conference were published as LNCS 2743.

This book contains the final reports of 19 workshops held during the 20th European Conference on Object-Oriented Programming, ECOOP 2006, held in Nantes, France in July 2006. The 19 reports cover the entire range of object technology and related topics, presenting a coherent and highly representative snapshot of the major trends in the field.
