Design and implementation of component-based adaptive Web presentations

Engineering adaptive Web applications implies the development of content that can be automatically adjusted to varying client devices and user preferences. To meet this requirement, the AMACONT project recently introduced a component-based XML document format. Configurable document components encapsulating adaptive behavior and layout are used on different abstraction levels in order to support flexible reuse for effective Web page generation. This paper focuses on the process of designing and implementing such component-based adaptive Web presentations. Based on the model-driven specification framework from the Hera project, different phases of adaptation design are identified and their realization using AMACONT components is explained. Finally, a pipeline-based document generator for dynamically publishing component structures to different Web output formats is described.
