Developer discussion for Creative Commons technology and tools

[Nathan Kinkade <nkinkade AT creativecommons.org>]

Hi Eduardo,

This is really more of a question for the cc-community list, as
cc-devel is more about software development related to CC.  I'm
cross-posting this to cc-community list.

Where did you get the idea that you could simply covert a CC BY PNG
image to JPEG format and release the work under a different and
compatible license?  As far as I understand the licenses, changing the
medium, or encoding of a digital file, is not enough to constitute a
derivative work, and therefore you would not be permitted to
re-license the work since it isn't actually a new, original work
(derivative).  As you note, you cannot simply take a CC-license work,
and arbitrarily apply some new license to it.

I have to admit that I'm confused about where you are confused.   In
what way do you believe the message of "copy and create derivatives"
is misleading?  Can you provide examples?  Creating a derivative work
implies copying it first; the two cannot be separated.

Best,

Nathan
