The GNU General Public License , better known by its English name GNU General Public License or just its initials in English GNU GPL is a license created by the Free Software Foundation in 1989 (the first version), and is aimed primarily at protect free distribution, modification and use of software . Its purpose is to declare that the software covered by this license is free software and protect ownership attempts to restrict these freedoms to users. There are several licenses
"sisters" of the GPL, as license GNU Free Documentation (GFDL), the Open Audio License for musical works, etc., and other less restrictive, as mgpl , or LGPL (Lesser General License publish it before publish it General License Library), which enable dynamic binding of free applications to non-free applications.
The GPL, as a document that gives certain rights to the user, takes the form of a contract, which usually is called a license agreement or license agreement. [ 1 ] [ 2 ] In Anglo-Saxon countries there is a doctrinal distinction between licenses and contracts, but this does not happen in civil law countries or continental. As a contract, the GPL must meet the legal requirements of contract formation in each jurisdiction.
The license has been recognized by courts in Germany , particularly in the case of a sentence in a Munich court , [ 3 ] positively indicating their validity in civil law jurisdictions.
Most free licenses such as MIT License and GPL is compatible with the GPL (see complete list of external links.) This means you can combine code licensed under GPL with code that is under a compatible license without any problem because the resulting code must satisfy the conditions of both licenses. However, others described as free licenses are not compatible with the GPL, which makes the reuse of code; therefore it encourages free software developers to license their code under GPL or GPL-compatible licenses, and can take advantage of the benefits that entails.
There is a proliferation of free licenses that add some condition to another compatible with the GPL license (which they are based), making it difficult to determine whether the new license is compatible or not with the GPL. This necessitates the use of experts, which was what initially was intended to avoid, so do not recommend this practice. (Source: Wikipedia )
