The folks at Creative Commons have posted a draft statement of intent regarding the CC-BY-SA license:

http://wiki.creativecommons.org/Draft_Attribution-ShareAlike_Intent

I've just read through it, and I'm really, really happy. Through this statement, CC has taken a first stab at defining in detail their intentions as stewards of the license. This is key to building trust with the Wikimedia community and other stakeholders in the free culture movement.

The statement of intent clarifies a number of key points, including a commitment to keep the license in compliance with the Definition of Free Cultural Works, and a strong promise to only broaden, but not narrow the definition of what constitutes an adaptation under the terms of the license.

We are continuing our conversations about that particular aspect, and my personal hope is that we will figure out a way to clearly state through the license that adaptations such as a picture embedded into a newspaper article trigger the share-alike clause, i.e. the newspaper article would be CC-BY-SA licensed. (Or, as I would argue, in those particular cases, any other DFCW compliant license.)

You can post comments regarding the draft on the wiki talk page, or on the cc-licenses mailing list: http://lists.ibiblio.org/mailman/listinfo/cc-licenses

This is a really important development, and I hope that everyone who cares about the future of free culture licenses will get involved in these conversations. :-)

My congratulations go to Creative Commons for taking this initiative.
