Abstract
Electronic commerce (e-commerce) and mobile commerce (m-commerce) have dramatically boosted the demand for services which enable ubiquitous access. Ubiquity offers opportunities in terms of time aware, location aware, device aware, and personalised services. Development of ubiquitous Web applications, however, turns out to be rather complex and thus requires appropriate methodological support. Existing methods for modelling Web applications only partially match the requirements resulting from their ubiquitous nature.
This article aims at filling this gap by presenting a UML based framework for modelling ubiquitous Web applications, focussing on issues of adaptation modelling. It encompasses both, context modelling by providing a physical and a logical context model, and modelling the adaptation process per se. The latter is realised in terms of a rule model enabling monitoring of context changes and activation of corresponding adaptation operations. The separation of a Web application in a stable and context independent part on the one hand and a variable and context dependent part on the other hand supports reusability and locality of change.
