Abstract: This paper introduces weave and existing model transformation techniques. According to the advantages and disadvantages of these te chniques, a new model transformation technique is presented based on Query/Views/Transformation (QVT) standard. Based on the above technique and the powerful function of model transformation in the language of Kermeta, a model transformation to ol of fourlayer structure was designed based on mapping by layering the core of QVT, implements the transformation from Ecore metamodel to Kmt metamodel.

Key words: model driven architecture, weave, transformation, layer
