The WebTaskModel Approach to Web Process Modelling

摘要

Task modelling has been entering the development process of web applications. However, modelling web processes from a usage-centred perspective is still challenging due to the strong distinctions of traditional interactive systems and state-of-the-art web applications. This paper proposes the WebTaskModel approach, by which task model concepts are adapted for the purpose of modelling interactive web applications. The main difference to existing task models is the introduction and build-time usage of a generic task lifecycle. Hereby the descriptions of exceptions and error cases of task performance (caused by, e.g., the stateless protocol or Browser interactions) are on the one hand appended to the task while, on the other hand, being clearly separated.
