This article provides a methodological approach that focuses on requirements engineering within the Model-Driven Development (MDD) context. Our approach is an OpenUP extension in which the requirements discipline is placed in the model-driven context. We believe that the integration of requirements engineering and MDD into one consistent process will provide practitioners with the benefits of both. This paper presents the definition of the proposed process, OpenUP/MDRE, including its activities, roles, and work products. We also provide an example of its use in a SOA-based software development project. The use of our approximation guides the activities of requirements engineering and promotes automation by means of model transformations.
