Flexible Graphical Editors for Extensible Modular Meta Models

Junker, Michael

Abstract: In model-driven software development, graphical editors can be used to create model instances more effciently and intuitively than with pure XML code. These graphical editors rely on models created on the basis of a meta-model. If such a meta-model is extended invasively not only its code has to be re-generated but also the graphical editor needs to be adapted. When developing multiple extensions, the meta-model as well as the corresponding graphical editor tend to get complex and error-prone. One way of coping with this complexity is to use modular meta-models and extending them noninvasively. However, having multiple meta-model fragments providing extended features is only half the job as equivalent graphical editors are needed as well. This master’s thesis therefore analyzes different types of extensions for meta-models as well as on graphical editor level. Next, a short analysis of extension mechanisms follows. These mechanisms are used for different realizations of extension types. Like the extension types, the mechanisms are also analyzed for both meta-models and for graphical editors. While the classiffcation of extensions resembles one part of this thesis’ concept, their mapping from meta-model level to graphical editor level marks the second part. This mapping is done in order to show possible impacts of a meta-model extension to its corresponding graphical editor. To validate this concept, the analyzed mappings are implemented exemplarily in two different frameworks. Furthermore, the two prototypes show the different possibilities each framework has to offer when it comes to their capabilities of extension. Therefore, this thesis can also be seen as guideline for extending a given graphical editor.
