Even though I work in the OER space with WikiEducator on an almost daily basis I have to admit that I continue to struggle with some of the finer bits of CC licenses and the whole balance between the various “frees”.
I think the distinction made between “free beer vs free speech” made in the “Gratis versus libre” article from Wikipedia really helped me out quite a lot. I’m starting to think of it less like a black and white thing and more like a series of interconnected steps or like nesting dolls (or Venn diagram-like circles).
One of the problems I’ve come across in my work on wikieducator is how to deal with some of these nesting issues: we had a screen shot created by a contractor (so he’s the author right?), on the screen was Powerpoint (so the author is Microsoft?), in the Powerpoint was a CC-BY-SA licensed photo (hoo boy! – is this guy the author?).. we’ve not really gotten a clear answer on this and it feels like we never will. What we reckon is that it was created by the contractor, we have to mention MS, and mention we’re using it for education AND say who the photo is by…
For my personal stuff (this blog, for instance) I think I’d go with but I honestly am not totally sure that this is the best choice. For instance would this preclude someone quoting something I wrote here in a newspaper article?
