This will make it easier for contributors to use wikipedia content in their metoCube Open Models.
“When I started Wikipedia, Creative Commons did not exist. The Free Documentation License was the first license that demonstrated well how the principles of the free software movement could be applied to other kinds of works. However, it is designed for a specific category of works: software documentation. The CC-BY-SA license is a more generic license that meets the needs of Wikipedia today, and I’m very grateful that the FSF has allowed this change to happen. Switching to CC-BY-SA will also allow content from our projects to be freely mixed with CC-BY-SA content. It’s a critically necessary change for the future of Wikimedia.”
