Diploma thesis

GenGMF is a project created as part of my diploma thesis. The german paper is – of course – available for download. The abstract follows below:

„base“ is a model-driven software development environment for internal use by „b+m Informatik GmbH Berlin“. For editing models in „base“ a tree-based editor has been used in the past, which builds on the Eclipse Modelling Framework (EMF). A tree representation in particular is difficult to manage for the dataflow model, because conceptionally the model represents a graph in the mathematical sense of the word. The objective of this thesis was essentially optimizing the developmental process in „base“. To this end, a graphic editor for dataflow models was developed on the basis of the Graphical Modelling Framework (GMF). The meta-model, on which the dataflow models are based, contains 20 element types, which can be placed directly in the editor’s drawing area. The complexity of the models used in GMF increases over proportionally though with the number of element types and is consequently difficult to administrate. This was the reason for developing „GenGMF“ instead of implementing a graphic editor with GMF itself. „GenGMF“ is a Domain Specific Language with an appropriate generic model-to-model transformation for the automatic construction of GMF models. The dataflow editor was modeled using this new development for the construction of graphic editors. Using „GenGMF“ for development of the dataflow editor allowed construction of a „GenGMF“ model requiring 72% less model elements than generated GMF models. In addition, it did not have to be manually adjusted. The result is ease of use for presentation in the graphic dataflow editor.

The GenGMF relevant parts are chapter 6 and 7.
