Development of Creative Commons licenses

["teun spaans" <teun.spaans AT gmail.com>]

Hi Erik,

At commons.wikimedia.org several forms of derivates are in frequent use:
* removing watermarks
* combined pictures where individual images are PD, CC-BY-SA or GFDL

Perhaps I misunderstand your proposal, but your proposed change seems to limit possibilities of the license under which many people published their images at both flickr and commons. That does not seem reasonable to me.

Also, please keep in mind that the derivatives at commons.wikimedia.org are not just combinations. These are a minority among the derivatives. Other frequent derivatives are the partly colouring of maps to highlight a town or provence, and the removal of watermarks.

kind greetings,
teun

As I've said, I'd be strongly in favor of changing the SA license to
require the combination of works in a strong semantic relationship to
trigger a secondary SA clause, where each component would have to be
licensed under a license which meets the criteria defined at

http://freedomdefined.org/Definition

but not necessarily the exact same license. This would allow us, at
Wikimedia, to combine pictures under CC-BY-SA with GFDL articles
without hesitation, but at the same time give photographers and
artists reasonable protection when they use the copyleft clause.

If there are no clear legal reasons not to do it, then it should be in
CC-BY-SA. I'll push the process of creating a new license if
necessary, but I don't think it should be. The current implementation
simply doesn't make an awful lot of sense for types of works where
derivatives are very rarely direct derivatives, and more frequently
semantic combinations. I don't see why this should be any more or less
legally problematic than, say, the NC restriction.

Copyleft should _mean_ copyleft, regardless of the type of work that
is being copylefted. The situation where music in a movie triggers
share-alike, and a picture in an article does not, is morally
unacceptable.
