GPLv3 improved compatibility with several free software licenses such as the Apache License, version 2.0, and the GNU Affero General Public License, which GPLv2 could not be combined with. [42] However, GPLv3 software could only be combined and share code with GPLv2 software if the GPLv2 license used had the optional "or later" clause and the ...
The following table compares various features of each license and is a general guide to the terms and conditions of each license, based on seven subjects or categories. Recent tools like the European Commissions' Joinup Licensing Assistant, [ 10 ] makes possible the licenses selection and comparison based on more than 40 subjects or categories ...
License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program.
A GNU license or GNU General Public License , is a series of widely-used free software licenses that guarantee end users the freedom to run, study, share, and modify the software. Version 1 was released 25 February 1989 by Richard Stallman and its last version (3) was published on 29 June 2007.
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components.
The Design Science License (DSL) is a strong copyleft license that applies to any work, not only software or documentation, but also literature, artworks, music, photography, and video. DSL was written by Michael Stutz after he took an interest in applying GNU-style copyleft to non-software works, which later came to be called libre works .
While version 2.1 of the LGPL was a standalone licence, the current LGPL version 3 is based on a reference to the GPL.. Compared to the GNU Classpath license above, the LGPL formulates more requirements to the linking exception: licensees must allow modification of the portions of the library they use and reverse engineering (of their software and the library) for debugging such modifications.
There are occasional edge cases where only one of the FSF or the OSI accept a license, but the popular free software licenses are open source, including the GPL. [72] Mitchell Baker drafted the Mozilla Public License while on Netscape's legal team. [73] Practical benefits to copyleft licenses have attracted commercial developers.
