Adaptability and adaptivity in the generation of web applications

This article proposes a generator for adaptive Web applications called GIWA. GIWA's objective is to facilitate the automatic execution of the design and the generation of Adaptable Web Applications (AWA). Characteristically, the effort in this work has to be pursued with special attention to both issues applied to AWA: adaptability and adaptivity. The architecture of GIWA is based on three levels: the semantic level, the conceptual level and the generation one. Using GIWA, designers specifies, at the semantic level the features of Web application. The conceptual level focuses on the creation of diagrams in WA-UML language; the extended UML by our new concepts and new design elements for adaptation. At the generation level, GIWA acquires all information about users' preferences and their access condition. Consequently, the generated pages are adaptable to all these information. An evaluation and a validation of GIWA are given in this article to prove our adaptation. [Article copies are available for purchase from InfoSci-on-Demand.com].© 2009, IGI Global.
