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).

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.weiterlesen
