Precise specifications are needed for verifying and certifying the correct behavior of critical systems. However, traditional proofreading and test based verification techniques are usually not exhaustive and as systems become more complex, their coverage is less and less adequate. Use of models allows early verification, validation and automated building of "correct by construction" systems. Our work targets formal specification and verification of model transformations. In a previous paper we tackled the problem of writing formal speci- fications for model transformations independently to the implementation technique. In this paper we investigate the implementation phase of these specifications as model transforma- tions using traditional MDE techniques and the difficulties encountered while generating the verification materials
