Hi,
I browsed through the free and open offering of the openvhb and stumbled upon a series of lectures on EU policy making [1]. It might be of interest to you.
From the teaser:
[...]. By attending this course, you will get an overview of the most important actors in European policy making and how they work together. Furthermore, the course will show you the basics of the European Migration and Asylum policy and what the Union has established so far. [...]
I have not signed up my self and don't need about software freedom at the openvhb.
Best, Christian
