Model transformation is one of the key tasks in the model-driven software development currently gaining more grounds in the industry. The Object Management Group (OMG) is committed to this paradigm and standardizes a set of tasks in its Model Driven Architecture (MDA) framework. After releasing the Meta Object facility (MOF) standard for model management, the long awaited standard for model transformation, Query/View/Transformation (QVT) has now been released. This makes it theoretically possible to exchange specifications of model transformations between different MDA tools, a significant contribution to interoperability. This document describes QVT 2.0 in general and how it can be used in the scope of ikv's medini QVT engine.
