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.
