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
