Which open source license has no forking [closed]

Question

I remember reading about an open source license which did not grant permission to fork.

I don't remember its name and thought it might be easier to ask here than to go through the entire list of OSI's approved licenses. Anyone knows which license I might be talking about?

Answer 1

First thing which comes to my mind is CC-ND: http://creativecommons.org/licenses/by-nd/2.0/

Answer 2

I suspect that you're embarking on a doomed quest here, given that item 3 of the OSI definition of an open source license seems to explicitly prohibit a clause that would prevent forking.
