A Multi-level Approach for Model-based User Interface Development

Multi-level modeling is considered to provide advancements over the traditional modeling approaches. It is applicable, among others, to scenarios where more than two classification levels are required and a rigid dichotomy between classes and objects needs to be relaxed. As the Model-Based User Interface Development (MBUID) inherently encompasses more than two classification levels, there are challenges which cannot be accounted for with the traditional approaches (e.g., the propagation of changes or the extensibility of modeling languages). Therefore, it seems promising to apply multi-level modeling for overcoming these challenges. In this paper, we show the applicability of the multi-level modeling language FMMLx and the language execution engine XModeler for the MBUID-field. As a proof of concept, a corresponding prototype based on FMMLx and XModeler is presented which illustrates the benefits of multi-level modeling.
