Elle seule savait ce qu'il y avait derrière la porte, mais elle ne pouvait pas parler, juste hurler d'effroi. Alors qu'elle avait tout juste trois ans, Mélanie a été enlevée, par son père, un psychologue passionné d'occultisme. Six ans plus tard, on retrouve la petite fille errant en état de choc dans les rues de Los Angeles. On découvre également son père, ou plutôt ce qu'il reste de son corps, mutilé, broyé. Mélanie, profondément traumatisée, ne sort de son mutisme que pour supplier que l'on referme une mystérieuse "porte sur l'hiver" et bientôt, en plein été californien, un vent glacial, inexplicable, balaie tout dans la maison. La porte sur l'hiver est entrouverte...

The fifth edition of the European Conference on Model-Driven Architecture Foundations and Applications (ECMDA-FA 2009) aimed to advance knowledge and promote the industrialization of Model-Driven Architecture (MDA) and Model-Driven Engineering (MDE). MDA, initiated by the Object Management Group, supports platform-generic systems development, while MDE encompasses a broader range of model-centric approaches. Both methodologies emphasize the use of models for specifying, designing, analyzing, synthesizing, deploying, and evolving complex software systems. The conference covered various MDA topics, including model transformations, modeling language issues, behavior and time modeling, traceability, scalability, model-based embedded systems engineering, and the application of model-driven development in IT and networking systems. ECMDA-FA 2009 fostered dialogue among key European and international researchers and practitioners, aiming to enhance industry efficiency and produce more reliable software grounded in cutting-edge research. This conference served as a vital forum for exchanging information, discussing recent findings, and debating future developments in MDA and MDE, uniquely bridging the gap between leading academic researchers and industry professionals to create synergies.

Models are crucial for the development, analysis, and evolution of large-scale, complex IT systems. They capture various views and elements of a system rigorously, enabling automated tools to manage them effectively. In a comprehensive model-driven engineering (MDE) process, model transformations are vital, as they define operations on models and facilitate the automated development of systems from these models. While model transformations are integral to model-driven approaches and several transformation languages and tools are nearing maturity, significant challenges remain. The research community and industry must deepen their understanding of model transformations, including the key concepts, operators, semantics, and structuring properties like modularity, composability, and parametrization. The impact of model transformations on organizations and development processes—especially in ultra-large scale systems or distributed enterprises—remains unclear. These challenges, along with issues related to the specification, design, implementation, analysis, and experimentation with model transformations, are the focus of ongoing discussions. The Second International Conference on Model Transformation took place in late June 2009 in Zurich, Switzerland.
