Hi https://wiki.sugarlabs.org/go/Sugar_Labs/FAQ#What_are_the_principles_that_guide_Sugar_Labs.3F says
What are the principles that guide Sugar Labs? Sugar Labs subscribes to principle that learning thrives within a culture of freedom of expression, hence it has a natural affinity with the free software movement (Please see Principles page in this wiki https://wiki.sugarlabs.org/go/Sugar_Labs#Principles for more details). The core Sugar platform has been developed under a GNU General Public License (GPL); individual activities may be under different licenses. That last sentence seems really weird to me, because as I understand the GPL, and I Am Not A Lawyer, then if Sugar is GPL, all Activities must be under GPL compatible libre software licenses. Eg https://github.com/walterbender/turtleart/blob/master/TurtleArtActivity.py#L35 is linking to sugar.activity, and so if https://github.com/sugarlabs/sugar-toolkit-gtk3/blob/master/src/sugar3/activity/activity.py was GPL, it would form a combined/derivative work. but in fact, while most of Sugar is GPLv2-or-later - https://github.com/sugarlabs/sugar/tree/master/docs has copies of GPLv2 and LGPLv2. https://github.com/sugarlabs/sugar/blob/master/COPYING is a copy of the GPLv2 https://github.com/sugarlabs/sugar-datastore/blob/master/COPYING is a copy of the GPLv2 (oddly without the preamble) https://github.com/sugarlabs/browse-activity/blob/master/COPYING is a copy of the GPLv2 These say GPLv2 or later in the top comment of the source code files, but the list of authors is not maintained: https://github.com/sugarlabs/sugar/blob/master/src/jarabe/main.py#L5-L7 https://github.com/sugarlabs/sugar-datastore/blob/master/src/carquinyol/datastore.py#L5-L7 https://github.com/sugarlabs/browse-activity/blob/master/browser.py#L7-L8 - I found that sugar-base and sugar-toolkit-gtk3 (and perhaps other 'core' parts) are LGPLv2.1-or-later: https://github.com/sugarlabs/sugar-base/blob/master/COPYING is a copy of the LGPLv2.1 https://github.com/sugarlabs/sugar-toolkit-gtk3/blob/master/COPYING is a copy of the LGPLv2.1 https://github.com/sugarlabs/sugar-base/blob/master/src/sugar/__init__.py#L5-L7 says LGPLv2.1-or-later https://github.com/sugarlabs/sugar-toolkit-gtk3/blob/master/src/sugar3/env.py#L6-L7 says LGPLv2.1-or-later So, I am curious :) Are there any proprietary Sugar activities? Have any parts of Sugar become GPLv3-or-later? The activities on ASLO have a variety of licenses, and it seems somewhat unmanaged. At random I picked http://activities.sugarlabs.org/en-US/sugar/addon/4548 and it has a copy of the LGPLv3, but the code headers says GPLv2-or-later. Is it ASLO policy to only host works licensed under GPLv2-or-later compatible licenses, or is another criteria used? -- Cheers Dave
