NOTE1: I was happy to contribute this piece to Inside Higher Ed and would be used to assigning to them the copyright in situations like this ... but I never had any discussion — and certainly not a written agreement — about the issue with them before the article appeared. Afterwards, I have asked them and they haven't answered specifically the issue about copyright ownership. Since copyright law is one of my side areas of interest, I have to say that in my inexpert opinion, the copyright would probably default to me: the only thing going against that would possibly be the works for hire doctrine, but I wasn't really hired to contribute my part to the article.... Anyway, if IHE wants to assert copyright ownership, I would be happy to talk to them about it!

NOTE2: Despite extensive research, it remains unclear to me who owns the copyright on MAFTIA deliverables — perhaps it is some branch of the EU? — and the MAFTIA web site does not clearly answer this question. In cases where this could be a concern, I suggest contacting one of the senior (former) MAFTIA organizers or perhaps the EU Information Society and Media Directorate-General (see this web site).
