Open MDA Using Transformational Patterns

No generally accepted understanding on the characteristics of MDA transformation mechanisms exists. Various approaches to support such transformations have been proposed. In this paper, we discuss general requirements for MDA transformation mechanisms. We claim that, above all else, transformation mechanisms should be open, i.e. clear, transparent and user-guided. We propose a new concept, a transformational pattern, as a basis of an MDA transformation mechanism. We exploit existing tool support for this concept and show a small example of how it can be applied. Finally, we analyse the ability of the proposed technique to fill the requirements.
