I'm inclined to agree that the PDFs in Poppler's test suite are "non-functional" for purposes of the FSDG. However, even for non-functional works, the FSDG requires that the license must allow copying and redistribution, both for commercial and non-commercial purposes. Here's the relevant text from the FSDG: Non-functional Data Data that isn't functional, that doesn't do a practical job, is more of an adornment to the system's software than a part of it. Thus, we don't insist on the free license criteria for non-functional data. It can be included in a free system distribution as long as its license gives you permission to copy and redistribute, both for commercial and non-commercial purposes. For example, [...] IANAL, but it seems fairly clear to me that the CC BY-NC-ND license does *not* permit copying and redistribution for commercial purposes. Specifically, section 4 paragraph 2 says: You may not exercise any of the rights granted to You in Section 3 above in any manner that is primarily intended for or directed toward commercial advantage or private monetary compensation. Note that section 3 is where permission to copy and redistribute is granted. Therefore, I think that in order to comply with the FSDG, we should use a snippet to remove any files covered by the CC BY-NC-ND license. What do you think? Thank you, Marius, for bringing this to our attention. Regards, Mark --=20 Disinformation flourishes because many people care deeply about injustice but very few check the facts. Ask me about .
