Preface The CAiSE conference has been a leading conference for the information systems engineering community for more than two decades, emphasizing different themes in each year. The special theme of CAiSE 2010 is "Evolving information systems", and it is devoted to the continuous evolution process of information systems and the methodologies and technologies supporting this process. The leading position of the CAiSE conference causes a fierce competition among papers, accompanied by a low acceptance rate. This poses an obstacle that hinders the acceptance of papers devoted to innovative research projects, whose results are interesting to the community, but not yet final and mature enough to be acceptable to the conference. As it is beneficial to the CAiSE community to be exposed to these ideas and to discuss and communicate about them even at this phase, the CAiSE Forum was created CAiSE Forum is a special event within the CAiSE conference. The Forum is intended to serve as an interactive platform for presenting and discussing new ideas related to information systems engineering. As such, it aims at the presentation of fresh ideas, new concepts, as well as demonstration of new and innovative systems, tools and applications. The Forum taking place at CAiSE 2010 is the eighth Forum event. Over the years different formats have been used for this event, seeking to increase the interactive nature and to better facilitate communication and exchange of ideas among its participants. The 24 high quality papers accepted for presentation in CAiSE Forum 2010 can roughly be categorized into two kinds of papers. One includes papers reporting innovative research projects, which were selected based on the novelty of the ideas they present. The second kind is papers devoted to innovative tools and prototypes that implement the results of research efforts. These tools and prototypes are presented as demos in the Forum event.
