This paper propose the approach for integrating SPEM modeling tools with the Query/View/Transformation (QVT) tools using Eclipse Modeling Framework (EMF). The aim of tool integration is to support the adoption of Model Driven Architecture within the organizations, which currently use “traditional” software development approaches. The software development process lifecycle of organization is supposed to be expressed with the help of OMG SPEM language. The approach presented in the paper is based on the model-level integration using EMF based interfaces, which will help to link the MOF based Ecore models with the QVT transformation tools. The outcomes of the work are: (i) the design of EMF based tool integration, (ii) solution prototype for Eclipse environment (iii) QVT Relations transformation rules. Model transformations are performed using mediniQVT tool, which is able to operate with the models expressed as Ecore metamodels and provides debugging features and transformation rules tracing. The QVT Relations transformations are applied to the source model, which corresponds to the “traditional” software development lifecycle. The outcome of such unidirectional transformation is the new software development process, which corresponds to the model-driven software development process. The generated target model is SPEM compliant, and can be imported into the external tool supporting SPEM models in Ecore.
