Message:

After some experiments with dynamical roles which allow lecturers to edit the score attribute of course tickets through the UI, I decided to discard the idea completely. It's not feasible and very dangerous to enable lecturers to edit course tickets directly: There are too many course tickets, too many lecturers and to many restrictions. The solution will be that lecturers export the course tickets of their courses, fill the score column and re-upload the csv file. This is still not easy to implement because we can't allow lecturers to access the data center directly. Further discussions are necessary ...
