Hi Danielo, I'm not a Lawyer, so the following text represent my understanding / opinion and may be wrong.
------- Some Info ------- TiddlyWiki uses the 3 clause BSD license [1]. It is a very permissive license. So you can do almost everything if the 3 clauses are met. Since the license text is hardcoded into TW, you basically don't need a separate tiddler with the license. .. But a link that mentions it from your license will help. MIT license [2] is even more permissive. - With BSD you *must include *the copyright notice. - With MIT you *shall *include the copyright notice. So you can include any MIT licensed SW into TW and declare your Software is BSD licensed, because that's allowed. ... but you can not change BSD to MIT, if you use 3rd party BSD software. .... If you are the copyright holder (you wrote the SW) you can do whatever you want :) CC - Creative Commons [3] is a set of licenses and tools [4] to create them. CC can be used for software and prose text. With CC you can create very permissive licenses eg: CC-BY [5] and you can create very restrictive license eg: CC-BY-NC-SA [6] Creative Commons licenses are easy to build. CC .. Creative Commons BY .. Attribution — You must give appropriate credit <http://creativecommons.org/licenses/by-nc-sa/4.0/#> NC .. NonCommercial — You may not use the material for commercial purposes <http://creativecommons.org/licenses/by-nc-sa/4.0/#>. SA .. ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license <http://creativecommons.org/licenses/by-nc-sa/4.0/#> as the original. ---------- Your question: Can I create a tool based on TiddlyWiki with a Creative Commons licence? Yes. You can create a tool based on TiddlyWiki, as long as you keep the BSD license for TW itself. Plugins may have there own licenses eg: BSD, MIT, CC-BY ... shown in the control panel Your own content can be CC-...... whatever you like. So you can create a prominent link to a License Tiddler with contains the info about the used licenses. eg: - TiddlyWiki uses a BSD license <https://github.com/Jermolene/TiddlyWiki5/blob/master/licenses/copyright.md> - Plugin licenses can be seen at the $:/ControlPanel - If not stated otherwise the content of this TW is available under the Creative Commons Attribution-ShareAlike License <http://en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_Attribution-ShareAlike_3.0_Unported_License> ; The above is just an example. ----------------- Wikipedia uses CC-BY-SA ------------------- With TW it is possible that every tiddler can have its own license. .. This isn't very convenient, .. but it's possible. hope that helps have fun! mario [1] http://en.wikipedia.org/wiki/BSD_licenses [2] http://en.wikipedia.org/wiki/MIT_License [3] http://creativecommons.org/ [4] http://creativecommons.org/choose/ [5] http://creativecommons.org/licenses/by/4.0/ [6] http://creativecommons.org/licenses/by-nc-sa/4.0/ [7] BSD template: http://opensource.org/licenses/BSD-3-Clause -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
