UML modeling languages and applications

The UML 2004 conference was held in Lisbon (Portugal) from October 11 through October 15, 2004. It was the seventh conference in a series of annual events that started in 1998. UML has rapidly become one of the leading venues to present and discuss the development of object-oriented modeling. In order to re? ect the changes in the ? eld, the UML conference series will be continued from 2005 onwards under the name MODELS (Model Driven En- neering, Languages and Systems).

This volume is a compilation of the contributions presented at these satellite events. Workshops at UML 2004 took place during the ? rst three days of the conference(fromOctober10to12). Followingthetraditionofprevious UML conferences, UML 2004workshopsprovidedacollaborativeforumforgroups of (typically 15 to 30) participants to exchange recent or preliminary results, to conduct intensive discussions on a particular topic, or to coordinate e? orts between representatives of a technical community. Ten workshops were held, covering a variety of hot topics, which have been covered in the workshop - ports contained in this volume. Each workshop lasted for a full day. A novelty with respect to previous UML conferences was the inclusion of a Doctoral Symposium, which was well received, to provide an explicit space for young - searchers developing their thesis on some aspect related to UML.
