Wikipedia to change licenses

Last November, version 1.3 of the GNU Free Documentation License gave Wikipedia a special permission to switch to the Creative Commons attribution-sharealike license license. The Wikimedia Foundation has now announced the result of the community's vote on the license change; over 75% (of over 17,000 voters) voted in favor. So it's now official: Wikimedia's sites will switch away from the FDL on June 15.

It's keeping GFDL

The new licence situation offers both GFDL and CC-by-sa. GFDL isn't being abandoned (with an exception for cases where existing cc-by-sa content is imported into Wikipedia, in those cases those sections will be cc-by-sa-only). IIRC.

GFDL is being abandoned in the sense that existing GFDL-only content is no longer allowed to be imported, whereas existing cc-by-sa-only content is allowed.

Yes, but that effect will be almost imperceptible. People almost never injected GFDL content into Wikipedia anyway. The case of >99.9% of contributions is original work, so the old situation was GFDL, and the new is GFDL+CC-by-sa (with a cornercase for allowing cc-by-sa-only content). I would have announed "CC-by-sa added as distribution option" rather than announcing that GFDL is being abandoned.

Well, you can count me as one of the people who have transferred GFDL content into Wikipedia. I am involved in PlanetMath, which is a collaboratively developed mathematics encyclopedia licensed under the GFDL. This move by Wikipedia basically requires us to switch to CC-by-sa as well if we want to maintain two-way compatibility. (It's worth mentioning that there are other compelling reasons besides Wikipedia compatibility to switch to CC-by-sa.)

cc-by-sa does indeed solve real problems. To avoid breaking other compatibility, it would be best to move to the same licence setup as Wikipedia - dual-GFDL+CC-by-sa, rather than just cc-by-sa.

That'll also have the practical advantage of keeping Wikipedia's licence situation clear because cc-by-sa-only stuff, wherever it exists in articles, will have to be somehow marked up as such.
