In model-driven user interface development, several models are used to describe different aspects of user interface when level of detail varies. The relations between the models are established through model transformations. The Model Driven Engineering (MDE) approach has been proposed in software engineering domain in order to provide techniques and tools to deal with models in the automated way. In this paper, we will review existing user interface languages that gain wider acceptance, and discuss their applicability for model-driven user interface development.
