When applying transformation technologies in an enterprise, there will be a need for supporting compositions of different kinds of transformations to support a development process. An example is a chain of transformations that supports a process of going from requirements to use cases, from use cases to a PIM architecture model, further to a platform specific model and finally implementation code. Some transformation steps may also involve human intervention, e.g. in arefinement of the PSM model, or a detailing of the use case model. This work in progress paper investigates how the atomic transformation viewpoint can be enhanced with support for transformation compositions, to support model driven enterprise process needs. This is done by introducing a modelling framework for composed transformations, based on a hierarchy of transformation types, some of which represent simple atomic transformations, others that represent complex transformations.
