Web Software Evolution by Aspect-oriented Adaptation Engineering

The evolving nature of the WWW necessitates to constantly adapt Web applications to new requirements, audiences, and client devices. However, as a given adaptation concern (e.g., device dependency) is typically deeply intertwined with different parts of the underlying application, it becomes difficult to adjust a Web-based system´s adaptive behavior to a new requirement. In this paper, we provide an aspect-oriented view on adaptation engineering within the AMACONT framework. By separating the specification of adaptation from the underlying application in the form of so-called adaptation aspects, we can thus easily add new or modify existing adaptation concerns on demand. We also present an extension of our graphical authoring tool AMACONTBuilder, allowing Web engineers to intuitively incorporate adaptation aspects into Web applications.
