Towards development of Web applications based on user interface services — a requirement analysis

In modern Web applications Web services are often used to encapsulate business logic to enable their reuse. By contrast User Interfaces are usually hand-crafted because standardized models for dynamic integration or reuse of UI components do not exist. We address this issue with an approach providing the dynamic and context-aware composition of User Interfaces based on exchangeable and customizable User Interface Services (UIS), which encapsulate UI parts. The central contribution of this paper is the discussion of the requirements for a runtime environment, which provides the novel approach of UI composition based on UIS.
