Building authoring applications is a tedious and complex task that requires a high programming effort. Document technologies, especially XML based ones, can help in reducing such an effort by providing common bases for manipulating documents. Still, the overall task consists mainly of writing the application's source code. Model Driven Engineering (MDE) focuses on generating the source code from an exhaustive model of the application. In this paper, we illustrate that MDE technologies can be used to automate the development of authoring application components, but fail in generating the code of graphical components. We present our framework, called Malai, that aims to solve this issue.
