repository must be compatible with GPLv2 or later. That means all code that is on our servers, from images to CSS to JS to the PHP code, has to meet that requirement. This is an extra requirement than just the standard one of derivative code, but we strongly feel that proprietary content has no need to be in our repository. If your code needs to be split licensed, or you have to included proprietary code for any reason, we can’t host you on .org, but that has no bearing on how neat and cool your code might be.</p> <p>For a list of various licenses, and their compatibility with GPLv2 please read this: <a href="https://web.archive.org/web/20130425151300/http://www.gnu.org/licenses/license-list.html" rel="nofollow">http://www.gnu.org/licenses/license-list.html</a> – We know not all of you are lawyers, and thankfully that list makes it easy to check what licenses do and don’t mesh. If something doesn’t have a license, ask the author please, and don’t assume.</p> <p>The following code bases are popular (which is to say we see submissions with them pretty regularly), but at the time of this post, are not licensed GPL-compatible. None of this means you can’t or shouldn’t use this code on your sites or plugins, just that we can’t host it <em>here</em> if you do.</p> <ul> <li><a href="https://web.archive.org/web/20130425151300/http://www.adobe.com/products/air/runtime-distribution1.html">Adobe Air</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://www.fancyapps.com/fancybox/#license">FancyBox v2 or later</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://fancyzoom.com/">FancyZoom</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://fortawesome.github.com/Font-Awesome/">Font Awesome</a> (<strong>Edit</strong>: Version 3.0 of may or may not be compatible, it’s confusing)</li> <li><a href="https://web.archive.org/web/20130425151300/http://flv-player.net/players/maxi/license/">FLV Player</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://shop.highsoft.com/highcharts.html" rel="nofollow">Highcharts</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://highslide.com/">Highslide</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://www.codebasehero.com/2011/06/html-music-player/">HTML 5 Music Player (Code Base Hero)</a> (only pre version 1.0.1 – <a href="https://web.archive.org/web/20130425151300/http://www.codebasehero.com/2011/07/html5-music-player-updated/">you can use this version</a>)</li> <li><a href="https://web.archive.org/web/20130425151300/http://imageflow.finnrudolph.de/">Imageflow</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://isotope.metafizzy.co/docs/license.html">Isotope</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://jpgraph.net/download/">JpGraph</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://leandrovieira.com/projects/jquery/lightbox/" rel="nofollow">jquery Lightbox</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://lokeshdhakar.com/projects/lightbox2/">LightBox2</a></li> <li><a href="https://web.archive.org/web/20130425151300/http://www.magictoolbox.com/license/">MagicToolbox</a></li> </ul> <p>If there are plugins you find using these (or any non-GPL-Compatible) code bases in their plugin, please <strong>email plugins AT wordpress.org</strong> and we’ll get in touch with the developer.

I meant that I’m using plugins found on the .org directory that contain jQuery Lightbox scripts IN the trunk svn repo hosted on the .org site. Many of those (see related comments) are carrying along scripts that specifically cite licenses that are NOT GPLv2 compatible, like the jQuery Lightbox script you reference in the original post.</p> <p>Now that those client sites are deployed I’m not so interested in that SPECIFIC issue. However my media streaming system will require pieces that are not readily available in GPLv2 format. I guess, based on your response to Mike, that I’ll have to find a way to marginalize those pieces and keep them out of the repo.</p> <p>Is it OK to say “if you want to use feature X” you will need to download “Y”? In my case I’d need a creative way to get the FLV player installed for the client listener. Thinking out loud here… Maybe hooks + filters that look for a “ride along” plugin that simply extends the feature set with “FLV fallback for non-HTML5 browsers”.</p> <p>Sorry for all the posts. I’m working on a big project and was planning on using WordPress as a key piece for the backend & front-end UI elements. Fully understanding this is kind of important before development starts in earnest next month. </p> <ul> <li>Lance</li> </ul> </div> <ul class="children"> <li id="comment-25865" class="comment byuser comment-author-ipstenu bypostauthor even depth-4"> <img alt="" src="https://web.archive.org/web/20130425151300im_/http://0.gravatar.com/avatar/abfd4ff9c24957f1a9f0435e23de1f73?s=32&d=http%3A%2F%2F0.gravatar.com%2Favatar%2Fad516503a11cd5ca435acc9bb6523536%3Fs%3D32&r=G" class="avatar avatar-32 photo" height="32" width="32"/> <h4> <a href="https://web.archive.org/web/20130425151300/http://halfelf.org/" rel="external nofollow" class="url">Ipstenu (Mika Epstein)</a> <span class="meta"> <abbr title="2012-12-20T19:41:27Z">7:41 pm <em>on</em> December 20, 2012</abbr> <span class="actions"> <a class="thepermalink" href="https://web.archive.org/web/20130425151300/http://make.wordpress.org/plugins/2012/12/20/gpl-and-the-repository/#comment-25865" title="Permalink">Permalink</a> | <a rel="nofollow" class="comment-reply-link" href="https://web.archive.org/web/20130425151300/http://make.wordpress.org/plugins/2012/12/20/gpl-and-the-repository/#respond" title="Reply" onclick="return addComment.moveForm("commentcontent-25865", "25865", "respond", "113")">Reply</a> </span> </span> </h4> <div id="commentcontent-25865" class="commentcontent"><p>The answer is ‘maybe.’</p> <p>If the entire use of your plugin hinges on non GPL code, then probably not.
