The Modeling in Software Engineering (MiSE) workshop series provides a forum for discussing the challenges associated with modeling software and with incorporating modeling practices into the software development process. The main goal of the series is to further promote cross-fertilization between the modeling communities (e.g., MODELS) and software-engineering communities.In particular, the workshop provides a medium to exchange innovative technical ideas and experiences related to modeling. The 2009 MiSE workshop provided a venue for presentation and discussion of eleven papers in the five areas of model evolution, domain specific languages, verification and validation, model transformation and state-of-the-art modeling usage in software development. These papers represent a 44% acceptance rate to the workshop. Three posters were also accepted. This report summarizes the discussions and conclusions of the workshop.
