Development of flexible process-centric web applications: An integrated model driven approach

In recent years, Model Driven Engineering (MDE) approaches have been proposed and used to develop and evolve WAs. However, the definition of appropriate MDE approaches for the development of flexible process-centric WAs is still limited. In particular, (flexible) workflow models have never been integrated with the models (e.g., presentation, information models) used in MDE approaches to develop this type of applications. In this paper, we propose an MDE approach for the development and the evolution of flexible process-centric WAs that integrates three MDE metamodels used to represent the main components of a WA with the metamodel of Declare. A case study, carried out to validate the feasibility, correctness and effectiveness of the proposed approach is presented and discussed.
