Happy Birthaday GPL v3

GNUInteresting article over at information week here discussing the 1st anniversary of the GPL v3 (GNU General Public License Version 3). Now although a discussion about Open Source licenses is a bit like naval gazing or in TWIT speak ‘inside baseball’, as with most legal issues what may not be very important today can become essential when things change (like ownership, control, intent etc.).


One of the software projects under the new GPL v3 is SugarCRM which is probably the most high profile commercial open source projects and as such comes in for plenty of praise and plenty of criticism. With the release of version 5 SugarCRM moved from the Sugar Public License (SPL) to GPL V3 (so they were never a user of GPL v2).

I thought it would be interesting have a look at the most well known Open Source Business Enterprise software projects (OK ‘most well known’ being a completely arbitrary list although I did look at the Sourceforge most active projects in the last 7 days ) to see what open source licenses they use. At this point please let me make it clear that I have no legal training and that the information below has been found on the web in various places, although I have tried to take most from the projects own website. Even if the list is 100% correct today it will no doubt become out of date very quickly. So, if the license that a piece of software is using is important to you, which I think it should be, I would confirm with the project directly. If you are thinking of using a piece of software in a ‘mission critical’ or even a mildly important area I would recommend taking professional legal advise from a person with software license knowledge. Anyway, upon researching I found the following (I have also put links to some of the articles I found at the bottom):

GNU Lesser General Public License v.3 (LGPL) from version 3 onwards



Many companies also offer an alternative commercial licenses including MySQL and Alfresco. Some Project previousley having licences with attribution clauses have moved to GPL V3. Although the GPL V3 is not worded as stronlgy as any attribution clause mentioned here although it does mention ‘The GPL requires all copies to carry an appropriate copyright notice’ this is expeted to be enforced as badgeware but inly time will tell.

Permitted Attribution License or ‘badgeware’ as it is sometimes called requires anyone using the code in a distributed form to show ‘for of attribution’ such as a logo or a badge on the user screens to show the source of the code. The applicable section from the Openbravo license is shown below. In the situation with SugarCRM and Vtiger, as
this clause was not in the license before there was no legal requirement for them to show any such badge and due to this SugarCRM changed their license to include this to stop this happening again.
