I just finished my studies and will soon start with my Ph.D. reseraches. During my diploma-thesis I developed an collaborative extension for GMF-editor to allow graphical shared-editing in GMF including conflict handling, authentification/authorisation, offline-mode etc. This thesis lead to the open source project Dawn
Although I digged deep into the code of GMF and did not work extensively with the diagram creation aspects of GMF I found it sometimes very uncomfortable to handle even a small number of figure descriptors. To improve this situation I decided to support the GenGMF project.
