A few years ago, we made the five-year effort to relicense the Mozilla codebase under the current tri-license so that our code could be used in more contexts and circumstances, without losing copyleft. This has been very successful, enabling projects like Songbird and Miro to happen which otherwise couldn’t due to licensing incompatibilities.
We’d now plan to do another similar, if smaller, thing. The Mozilla project, and the world, has been moving towards Creative Commons licences for non-code content. This is the licence used by the Mozilla Developer Centre and by www.mozilla.org. However, anomalously, wiki.mozilla.org is currently under the GNU FDL (Free Documentation Licence). This is for no other reason than it was the MediaWiki default at the time we set it up, and we inadvertently neglected to change it.
The GNU Project have generously added a relicensing clause to the most recent version of the FDL, 1.3, to allow FDL wikis to relicense under Creative Commons CC-BY-SA. wiki.mozilla.org is eligible to use this exception. We plan to use it to make our wiki content solely CC-BY-SA, and so interoperable with MDC, www.mozilla.org and the vast body of other Creative Commons-licensed content around the world. We believe that this is consistent with contributors’ expectations based on their experience with other Mozilla sites, and it will simplify moving wiki.mozilla.org content to other such sites and remixing it with content on those sites.
We want to be sure that people are OK with this, so if you have an objection, please post it in the newsgroup thread in the mozilla.legal group.
