| **Copyleft** refers to licenses that allow derivative works but require them to use the same license as the original work. For example, if you write some software and release it under the GNU General Public License (a widely-used copyleft license), and then someone else modifies that software and distributes their modified version, the modified version must be licensed under the GNU GPL too — including any new code written specifically to go into the modified version. Both the original and the new work are Open Source; the copyleft license simply ensures that property is perpetuated to all downstream derivatives. (There is at least one copyleft license, the Affero GPL, that even requires you to offer the [[dido:public:ra:xapend:xapend.a_glossary:s:sourcecode|source code]], under the AGPL, to anyone to whom you make the software's functionality available as a network service — however, most copyleft licenses activate their share-and-share-alike [[dido:public:ra:xapend:xapend.a_glossary:r:requirement|requirement]] on distribution of a copy of the software itself. You should read the license to understand its requirements for source code distribution.) | **Copyleft** refers to licenses that allow derivative works but require them to use the same license as the original work.
