Multiview Components for User-Aware Web Services

Component based software (CBS) intends to meet the need of reusability and productivity. Web service technology leads to systems interoperability. This work addresses the development of CBS using web services technology. Undeniably, web service may interact with several types of service clients. The central problem is, therefore, how to handle the multidimensional aspect of service clients' needs and requirements. To tackle this problem, we propose the concept of multiview component as a first class modelling entity that allows the capture of the various needs of service clients by separating their functional concerns. In this paper, we propose a model driven approach for the development of user-aware web services on the basis of the multiview component concept. So, we describe how multiview component based PIM are transformed into two PSMs for the purpose of the automatic generation of both the user-aware web services description and implementation. We specify transformations as a collection of transformation rules implemented using ATL as a model transformation language.
