Coupling MDA and Parlay to increase reuse in telecommunication application development

MDA (Model-Driven Architecture) has been coined by OMG (Object Management Group) as the next step in application integration. Being based on standards already embraced by a large segment of the software engineering industry, MDA promises fully automatic model transformation. MDA enables application developers to use formalisms such as UML to specify their applications in a totally platform-independent way. Later transformations to platform-dependent software are automated. Parlay, a middleware specification developed for the telecommunication domain, is on the other hand promising network independent development and deployment of telecommunication services and applications. In this position paper we report on our experience from a Eurescom project where we try to couple MDA and Parlay in order to increase reuse in the telecommunication domain. Telecommunication service development is hampered by long development cycles and low level of reuse. We describe how MDA approach can be applied to telecommunication domain through the use of Parlay. We believe this approach has substantial potential for reducing development costs for many telecommunication operators. In addition, developed models and applications can be deployed on a wide variety of platforms without
