On the maintenance of UI-integrated mashup applications

This paper describes the maintenance of long-lived mashup applications that are integrated at the user interface (UI) layer. It presents techniques that help mashup developers to maintain applications by identifying when and how the original applications´ UIs change. It describes a novel mashup editing environment that can be used to create, share, and edit mashups. This paper also presents an experiment that demonstrates our approach´s ability to track UI changes as an application evolves and a demonstration of the effort expanded by developers to maintain mashups as the applications used by the mashups evolve.
