The final comment period for the CC 4.0 license suite
The Creative Commons has announced the
posting of the third and final draft of the 4.0 license suite and the
beginning of the last comment period. "
In this third discussion period, we will be returning our attention to ShareAlike compatibility, the centerpiece of our interoperability agenda. We will take a harder look at the mechanism necessary to permit one-way compatibility out from BY-SA to other similarly spirited licenses like GPLv3, and whether one-way compatibility is, in fact, desired."
