However, the Wikimedia community is committed to principles of free information similar to the principles that have been articulated for software by the <a href="https://en.wikipedia.org/wiki/Free_software" class="extiw" title="w:Free software">free software</a> and <a href="https://en.wikipedia.org/wiki/Open_source" class="extiw" title="w:Open source">open source</a> movements, allowing anyone to re-use the information for any purpose. This is accomplished through <a href="https://en.wikipedia.org/wiki/License" class="extiw" title="w:License">licenses</a> which grant freedoms that people would not have under traditional copyright.</dd> <dd>The license chosen for Wikipedia is the <a rel="nofollow" class="external text" href="http://www.gnu.org/copyleft/fdl.html">GNU Free Documentation License</a> (GFDL) developed and maintained by the <a rel="nofollow" class="external text" href="http://www.fsf.org/">Free Software Foundation</a>. Underscoring the deep connection between Wikipedia and the free software community, this license was originally developed for freely licensed software documentation. However, as Wikipedia and the other projects have grown and continued to expand rapidly, it has become increasingly apparent that Wikimedia is no longer as suited to this license as it may once have been. Therefore, to make Wikipedia content easier to use and legally compatible with existing free content projects, the Wikimedia Foundation intends to submit a proposal to the Wikimedia community to make all content currently distributed by the Wikimedia Foundation under the GFDL available under the <a rel="nofollow" class="external text" href="http://creativecommons.org/licenses/by-sa/3.0/">CC-BY-SA 3.0</a> license, where CC-BY-SA will exclude GFDL whenever third party content only licensed under the CC-BY-SA license is imported; this, as well as why the CC-BY-SA is proposed to be more fitting, is explained in detail below.</dd> <dd>The GFDL has been recently updated in a fashion to make this re-licensing possible without direct petitioning of each copyright holder who contributed to a collaborative work (see below). The decision on whether to update the licensing terms is nevertheless intended to be democratically made through a global, community-wide vote, where a simple majority of qualified users will constitute sufficient support to make this switch. The vote has begun by early April, and will end on May 3rd.</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Why_move?" data-mw-thread-id="h-Why_move?"><span id="Why_move.3F"></span><span data-mw-comment-start="" id="h-Why_move?"></span>Why move?<span data-mw-comment-end="h-Why_move?"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Licensing_update/Questions_and_Answers&action=edit&section=2" title="Edit section: Why move?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>Why is the Wikimedia Foundation interested in moving from the GNU Free Documentation License (GFDL) to the Creative Commons Attribution Share-Alike license (CC-BY-SA)?</dt> <dd>To begin with a quote by Jimmy Wales: <dl><dd>"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."</dd></dl></dd> <dd>The GFDL was originally formulated to address a specific set of problems, including the possibility that some companies might use non-free documentation as a way of encumbering otherwise free software. The design decisions that went into development of a documentation license don't always address the problems that come up with massive multi-user collaboration projects like Wikipedia, and they may in fact create new problems that make free content less easy to use.</dd> <dd>This is a large part of the reason why Creative Commons has designed a specific generic <a href="https://en.wikipedia.org/wiki/Copyleft" class="extiw" title="w:Copyleft">copyleft</a> license for works which are not software, the CC-BY-SA license. The Creative Commons licenses have seen rapid adoption on the web, with more than 130 million works estimated to be licensed under one of them <i>(see <a rel="nofollow" class="external text" href="http://wiki.creativecommons.org/Metrics">Creative Commons Metrics</a> for statistics)</i>. Unfortunately, works under CC-BY-SA and GFDL cannot directly be combined, creating an unnecessary but highly problematic compatibility barrier within the free culture movement.</dd> <dd>The Free Software Foundation (which maintains the GFDL), Creative Commons (which maintains the CC-BY-SA license), and the Wikimedia Foundation (which operates Wikipedia among other free-culture projects) have been working together to develop a pathway to "migrate" or "re-license" Wikipedia content (and the content of similar wikis) to the CC-BY-SA license that combines the free-culture values of the GFDL with greater practical usability in the context of collaborative works.</dd> <dd>A review of <a href="/wiki/Licensing_update/License_comparison" title="Licensing update/License comparison">our comparison of the two licenses</a> might also be helpful in answering this question.</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Why_is_GFDL_a_problem?" data-mw-thread-id="h-Why_is_GFDL_a_problem?"><span id="Why_is_GFDL_a_problem.3F"></span><span data-mw-comment-start="" id="h-Why_is_GFDL_a_problem?"></span>Why is GFDL a problem?<span data-mw-comment-end="h-Why_is_GFDL_a_problem?"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Licensing_update/Questions_and_Answers&action=edit&section=3" title="Edit section: Why is GFDL a problem?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>In which way has the GFDL, which seems to me to have worked just fine, been a problem for Wikipedia or its communities of editors and users?</dt> <dd>Community member David Gerard has provided a nice summary of the issues for us, so in the spirit of reusing useful content, we're adapting his summary: <dl><dd>The GFDL was written as a license for software manuals on paper with one or a few authors. It's not at all suited to wiki content with possibly hundreds of editors. Wikipedia's predecessor, Nupedia, eventually adopted it at the time because the CC-BY-SA license didn't exist yet.</dd> <dd>The GFDL is very difficult to follow in practice, at least in contexts like massive multiuser collaborative projects like Wikipedia.</dd> <dd>Trying to obey can be onerous. Per the letter of the license, every significant (greater than fair use) quotation from a GFDL work needs a copy of the license (three or so pages of print) attached. GFDL content is almost impossible to reuse in audio or video content for this reason.</dd> <dd>Although easy to follow on the web (link to a local copy of the GFDL) or in a book (reproduce the three-page license), it's almost impossible to reuse in shorter pieces.</dd> <dd>The 'how to comply' pages on various Wikipedias are more what individual editors think is a good idea, not necessarily what the letter of the license says – as has been complained of by reusers accused of violation for not following this month's interpretation.</dd> <dd>Even cutting and pasting text between two Wikipedia articles is technically a violation unless the full author list for that piece of text is attached. This is not workable on a wiki.</dd> <dd>CC-BY-SA is becoming the usual license for free content intended to stay free ('copyleft'). That's a whole world of text, images, movies and so on that Wikimedia stuff can't be mixed with. (A software analogy is using a copyleft license that's not GPL-compatible – it makes your work an isolated island for no particular gain.)</dd></dl></dd> <dd>It is also worth pointing out that a literal interpretation of the attribution requirement of the GFDL requires complete duplication of the "history" section of the article with every derivative work (not just the author names – the entire section). For an article with thousands of revisions, this is obviously highly onerous, but even with just a smaller number of revisions, it is a significant amount of text.</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="The_history" data-mw-thread-id="h-The_history"><span data-mw-comment-start="" id="h-The_history"></span>The history<span data-mw-comment-end="h-The_history"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Licensing_update/Questions_and_Answers&action=edit&section=4" title="Edit section: The history"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>What is the history of the negotiations to allow this migration to happen?</dt> <dd>This migration path has been the subject of discussions among the FSF, Creative Commons, and the Wikimedia Foundation for several years. These have been friendly discussions, and the participants have all shared the goal of ensuring that "relicensed" or "migrated" content is strongly free, and consistent with strong "copyleft" principles. To some extent the discussions have centered on a widely acknowledged fact – that Wikipedia is one of the largest pools of free information, but because of licensing issues it can't always be easily reused, remixed, and combined with other stuff available under the somewhat different but similarly intentioned CC-BY-SA license (which is widely used elsewhere on the Net). In fact, several other Wikimedia Foundation projects also use CC-BY-SA, so one of the goals here is to bring Wikipedia licensing into greater harmony with that of other Wikimedia Foundation project content.</dd> <dd>On December 1, 2007, the Wikimedia Foundation Board of Trustees made the important <a href="https://foundation.wikimedia.org/wiki/Resolution:License_update" class="extiw" title="wmf:Resolution:License update">decision</a> to officially request the implementation of a migration path to CC-BY-SA in the GFDL 1.3 license. This decision also included a commitment to "community discussion and voting" before any change would be implemented on Wikimedia Foundation websites.</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="November_1_2008_date" data-mw-thread-id="h-November_1_2008_date"><span data-mw-comment-start="" id="h-November_1_2008_date"></span>November 1 2008 date<span data-mw-comment-end="h-November_1_2008_date"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Licensing_update/Questions_and_Answers&action=edit&section=5" title="Edit section: November 1 2008 date"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>I notice the date for eligibility of relicensable content is November 1, 2008 – that date has already come and gone.

As the Free Software Foundation indicates in its own <a rel="nofollow" class="external text" href="http://www.gnu.org/licenses/fdl-1.3-faq.html">FAQ</a>: "if a work was originally published somewhere other than a public wiki, you can only use it under CC-BY-SA 3.0 if it was added to a wiki before November 1, 2008. We do not want to grant people this permission for any and all works released under the GFDL. We also do not want people gaming the system by adding GFDLed materials to a wiki, and then using them under CC-BY-SA afterwards. Choosing a deadline that has already passed unambiguously prevents this."</dd> <dd>This does not affect our ability to migrate content originating in our wikis, only the ability to re-license content originating outside the Wikimedia Foundation wikis.</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="August_2009_date" data-mw-thread-id="h-August_2009_date"><span data-mw-comment-start="" id="h-August_2009_date"></span>August 2009 date<span data-mw-comment-end="h-August_2009_date"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Licensing_update/Questions_and_Answers&action=edit&section=6" title="Edit section: August 2009 date"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>Isn't the FSF granting this permission and then removing it down the line – in August 2009?

The goal of this negotiation has not been to make it forever easy to switch among free licenses but to address the fact that the basic license for Wikipedia (and many similar wikis) is a license that was not particularly well-suited for wiki collaboration because it was developed for a different set of purposes. As the FSF FAQ puts it: "[T]his permission is no longer available after August 1, 2009. We don't want this to become a general permission to switch between licenses: the community will be much better off if each wiki makes its own decision about which license it would rather use, and sticks with that. This deadline ensures that outcome, while still offering all wiki maintainers ample time to make their decision."</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Replacing_GFDL_with_CC-BY-SA?" data-mw-thread-id="h-Replacing_GFDL_with_CC-BY-SA?"><span id="Replacing_GFDL_with_CC-BY-SA.3F"></span><span data-mw-comment-start="" id="h-Replacing_GFDL_with_CC-BY-SA?"></span>Replacing GFDL with CC-BY-SA?<span data-mw-comment-end="h-Replacing_GFDL_with_CC-BY-SA?"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Licensing_update/Questions_and_Answers&action=edit&section=7" title="Edit section: Replacing GFDL with CC-BY-SA?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>So are you basically trying to replace the GFDL on Wikipedia with CC-BY-SA?</dt> <dd>No, we are proposing that all content currently available under GFDL will also be made available under the CC-BY-SA license, and that all future revisions must be dual licensed, with the exception of CC-BY-SA-only additions from external sources.

How are you going to administer it?</dt> <dd>It simply means that content will be available under both the GFDL and CC-BY-SA licenses simultaneously, unless some CC-BY-SA-only materials are imported and incorporated into that piece of content. In other words, reusers will be able to choose whether to reuse Wikipedia content under the GFDL license or the CC-BY-SA license (with a few exceptions). We have worked with FSF and others to try to implement dual-licensing in a way that requires relatively little administrative overhead (or editor or user overhead). The outline of this arrangement were spelled out in e-mail by Richard Stallman, who was mindful of the need to make the problems of dual-licensing manageable: <ul><li>ALL contributors agree to the following: <dl><dd>Wikipedia can release their newly written text under both GFDL and CC-BY-SA in parallel. However, if they imported any external material that's available under CC-BY-SA and not under GFDL, Wikipedia is bound by that.</dd></dl></li> <li>All old revisions are released under GFDL and CC-BY-SA.</li> <li>All new revisions are released with this license statement: <dl><dd>This page is released under CC-BY-SA. Depending on its editing history, it MAY also be available under the GFDL; see [link] for how to determine that.</dd></dl></li></ul></dd></dl> <dl><dt>Isn't dual-licensing a complicated solution to this situation?</dt> <dd>We believe Richard has done well at outlining an appropriate implementation for dual-licensing – we believe that this dual-licensing compromise should ideally allow both dual-licensing proponents and dual-licensing opponents to support the switch. We recognize that this compromise won't fully please everyone, but hope neither the pro-dual-licensing side nor its opponents will dig their feet in. Part of the reason to keep GFDL integrated in the way we are proposing here is precisely that the GFDL has been of unquestionable value for Wikipedia over the years. We recognize that FSF is going forward in its own efforts to revise and evolve the GFDL. If you help us move forward with this compromise, we can revisit the dual-licensing situation in a year or two together with the FSF and see if it still is needed.</dd> <dd>It will be the obligation of re-users to validate whether an article includes CC-BY-SA-only changes – dual licensing should not be a burden on editors. This is also not intended to be bidirectional, so merging in GFDL-only text will not be possible.</dd></dl> <dl><dt>What about merging in GFDL-only content?</dt> <dd>While merging GFDL-only text into WikiMedia projects will ultimately no longer be possible, we propose to continue to permit GFDL 1.2-only media uploads for the foreseeable future, to address concerns regarding strong and weak copyleft, until such concerns are fully resolved to the satisfaction of community members. <i>(For a discussion of "strong copyleft" versus "weak copyleft," see generally the Wikipedia <a href="https://en.wikipedia.org/wiki/en:Copyleft" class="extiw" title="w:en:Copyleft">entry on "Copyleft"</a>.)</i></dd></dl> <dl><dt>How will re-users determine whether or not an article is available under GFDL?</dt> <dd>The CC-BY-SA license requires attribution, so when third party content is imported under "CC-BY-SA-only", it will have to be noted who the author is and that it was released under CC-BY-SA, as part of the normal, existing procedures through which projects make note of such histories (we recommend the article footer or the version history). Re-users will have to consult this information to determine whether CC-BY-SA-only content has been imported.

At the same time, the Creative Commons free licenses had not been developed (or at least not in their current form). So GFDL at the time was the best option available.

Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns." The use of the GFDL by Wikipedia has given rise to "new problems or concerns", which were addressed by giving a migration path to a license "similar in spirit" which is, however, simpler to use in the context in which we are currently using the GFDL. While the specific wording of CC-BY-SA is different from that of the GFDL, the freedoms it guarantees and preserves are identical, and thanks to the <a rel="nofollow" class="external text" href="http://wiki.creativecommons.org/CC_Attribution-ShareAlike_Intent">Statement of Intent</a> by Creative Commons, are guaranteed to be protected in the long term.

Our own terms of use (e.g. <a href="https://en.wikipedia.org/wiki/en:Wikipedia:Copyrights#Example_notice" class="extiw" title="w:en:Wikipedia:Copyrights">English Wikipedia example notice</a>) have generally allowed people to give credit by referencing the article or history page, but those terms did not meet the requirements of the GFDL to the letter. The History page reachable from a Wikipedia article could be interpreted as not being a "section" or a "named subunit" as required by the license (it can also be on a different server than the page's one); similarly, there's not a Title page.</dd> <dd>Given our own existing site terms as well as the actual ways in which credit is given in Wikipedia to a contributor, we believe a consistent approach to attribution in Wikipedia is to state a requirement to attribute articles by linking to them. CC-BY-SA allows for this attribution model, as it permits the author to require attribution-by-name or attribution-by-URL. That this approach is consistent with the language and intent of CC-BY-SA has been validated by Creative Commons General Counsel. An <a href="https://foundation.wikimedia.org/wiki/File:Attribution_Survey_Results.pdf" class="extiw" title="wmf:File:Attribution Survey Results.pdf">exploratory survey</a> conducted in the English and German Wikipedia also suggests that this model is the preferred attribution model by the Wikipedia community and represents the best reconciliation of our desire to credit authors, and our mission to facilitate the free exchange of knowledge.</dd> <dd>The "History" section of GFDL documents exists for purposes of change tracking.
