Abstract

Ubiquitous web applications (UWA) are required to be customizable, meaning that their services need to be adaptable towards the context in which they are used, indicated by, e.g., user, location, time, and device. Considering UWA’s from a software engineering point of view, a systematic development on basis of models is crucial. Current web modeling languages, however, often disregard the crosscutting nature of customization potentially affecting all parts of a web application, i.e., its content, hypertext and presentation levels, and often tangle customization functionality and other, non-ubiquitous core services of a web application. This leads to inefficient development processes, high maintenance overheads and a low potential for reuse. To cope with this, we regard customization as a crosscutting concern in the sense of the aspect-oriented paradigm. As a proof of concept, we extend the prominent web modeling language WebML on basis of our reference architecture for aspect-oriented modeling. This allows for customization mechanisms to influence all parts of a web application, maintaining at the same time a clear separation between the core services and customization functionality, and – as a spin-off – demonstrates how to bridge existing (domain-specific) modeling languages with aspectoriented concepts
