The MODELS series of conferences is the premier venue for the exchange of innovative technical ideas and experiences relating to model-driven approaches inthedevelopmentofsoftware-basedsystems.Followingthetraditionofprevious conferences, MODELS2009hostedseveralsatelliteeventsinDenver.Therewere ten workshops and two symposia. The selection of the workshops was performed by a Workshop Committee, which consisted of the following experts: - James M. Bieman, Colorado State University, USA (Chair) - Peter Clarke, Florida International University, USA - Holger Giese, University of Paderborn, Germany - Frank Weil, Hengsoft, USA The workshops and symposia were held during the ?rst three days of the conference. They provided a collaborative forum for groups of participants to exchange recent and preliminary results, conduct intensive discussions on a p- ticular topic, and to coordinate e?orts between representatives of a technical community. They discussions were lively and the attendance was high. The focus of the Educators'Symposium was on sharing experience related to teaching modeling techniques and on developing resources to support e?ective training of future practitioners of model-driven development. The DoctoralSymposiumprovideda forumin whichPhDstudents presented their work in progress. The symposium fostered the role of MODELS as a p- mier venue for research in model-driven engineering. The symposium provided the students with independent and constructive feedback about their already completed work, and more importantly, their planned research work.
