I do not believe there is any point to having a copyleft license for media which isn't strong. Does anyone here disagree?
At the risk of being stoned... yeah. I just don't consider an article that uses a photograph of mine as illustration to be a a derivative of my work. I don't want an article, blog or book author to have to license their whole text under CC-BY-SA just because they use my image. HOWEVER, I do want them to be obliged to make explicit the license of my work, that is offer it to others under the same conditions. My work, not theirs. That is how I think "weak copyleft" differs from CC-BY or PD.
Actually, this *is* how CC BY works. The requirements of CC BY include both attribution of authorship (including a linkback) and notification of the license.
After rereading the CC-BY legal code it does appear you (and others who made this point) are correct, and I was quite mistaken about the strength of the CC-BY license. http://creativecommons.org/licenses/by/3.0/legalcode "You may Distribute or Publicly Perform the Work only under the terms of this License."
Indeed it seems CC-BY is already the "weak copyleft" I was thinking CC-BY-SA is... CC-BY is much stronger than I realised. I thought CC-BY just meant "include a byline with my name".
I am probably not the only one who had this impression, because the Wikimedia Commons summary as it stands is deeply misleading. http://commons.wikimedia.org/wiki/Template:Cc-by-3.0
How embarrassing.
So, is this understanding correct: using CC-BY, a reuser could create a derivative work that was not freely licensed, but provide info that the source image was CC-BY (and provide link), and that would be acceptable? Is that true?
Well... now I think shoring up CC-BY-SA to be a strong copyleft is a good idea, since Greg is correct...if we can correct the misperceptions of people like me then I don't see why this idea wouldn't receive widespread support.
cheers, Brianna
