Abstract
The Model-Driven Development (MDD) paradigm is currently being taken interest in the field of Software Engineering (SE). It allows simplification and automation of the development process by defining models and transformations of those models. Model-Based User Interface Development (MBUID) is a variant of the MDD paradigm in the domain of UI development. It aims to reduce the efforts needed to develop UIs. It has had a significant research by the SE community leading to the definition of the Cameleon Reference Framework (CRF) as a unifying framework which structures the UI development process. In the last few years, several research works have been conducted with the aim of proposing a Cameleon-compliant UI development process. This situation leads to a series of important shortcomings; among them we quote in particular the lack of consensus (standard) about the information the different models have to contain and how to transform these models. With the aim of solving this issue of giving a uniformed UI development process, this paper presents an initiative towards uniformed task model and its transformation to an abstract user interface.
