The Board of Trustees of the Wikimedia Foundation
invites the Wikimedia
community to vote on this proposal to license Wikimedia material so it
is available under the Creative Commons Attribution-ShareAlike license
(CC-BY-SA), while retaining dual licensing with the GNU Free
Documentation License. The Board has evaluated possible licensing
options for Wikimedia material, and believes that this proposal is the
best available path towards achieving our collective goal to collect,
develop and disseminate educational material, and make it available to
people everywhere, free of charge, in perpetuity.
To elaborate a little further, speaking now in a personal capacity.
Exploring the fine details of copyleft licensing gets into complex
issues, some of which we've debated on this list. The complexity means
many subtly different positions are possible, and we could probably
debate endlessly without reaching ideal solutions to those subtle
differences. That's part of why (as mentioned) individual board and
staff members, like everyone else, are free and encouraged to express
their own views about these matters.
By comparison, though, the vote we will have is more simple and
straightforward. It's not an effort to create a platonically perfect
license in the ideal world, which is likely impossible, rather it's
asking whether the relicensing allowed by the GFDL 1.3 is progress in a
practical sense. I think that's what we mean in agreeing that this is
the "best available" course at this time.
