Such a requirement is a restriction on use, because it requires you to cite the software when you use it, even if the manner in which you are using it is incompatible with citation. For example, a newspaper article which doesn't use citations, etc. > Can works with a citation requirement go into main?

GPL v3 allows licensees to remove additional restrictions when the work is conveyed to them, and the requirement to cite is clearly an additional restriction which is not allowed under GPL3 ยง7. I would contact the openmps group, and explain to them that they should just make their citation requirement a suggestion. [Any scientific paper or work is going to cite them anyway, so there's no need to require it.] > [2] <http://sourceforge.net/p/openmps/code/HEAD/tree/trunk/gpl3-cite.txt> -- Don Armstrong http://www.donarmstrong.com Information wants to be free to kill again. -- Red Robot http://www.dieselsweeties.com/archive.php?s=1372 -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
