Permissive software licenseA permissive software license, sometimes also called BSD-like or BSD-style license, is a free-software license which instead of copyleft protections, carries only minimal requirements on how the software can be used, modified, and redistributed, usually including a warranty disclaimer. Examples include the GNU All-permissive License, MIT License, BSD licenses, Apple Public Source License and Apache license.
Mozilla Public LicenseThe Mozilla Public License (MPL) is a free and open-sourceweak copyleft license for most Mozilla Foundationsoftware such as Firefox and Thunderbird.

Software licenseA software license is a legal instrument governing the use or redistribution of software. Since the 1970s, software copyright has been recognized in the United States. Despite the copyright being recognized, most companies prefer to sell licenses rather than copies of the software because it enables them to enforce stricter terms on redistribution.
Richard StallmanAmerican activist and programmer (born 1953)Richard Matthew Stallman ( ; born March 16, 1953), also known by his initials rms, is an American free software movement activist and programmer. He campaigns for software to be distributed in such a manner that its users have the freedom to use, study, distribute, and modify that software. Software which ensures these freedoms is termed free software.
Derivative workIn copyright law, a derivative work is an expressive creation that includes major copyrightable elements of a first, previously created original work (the underlying work). The derivative work becomes a second, separate work independent from the first. The transformation, modification or adaptation of the work must be substantial and bear its author's personality sufficiently to be original and thus protected by copyright.
Free Art LicenseThe Free Art License (FAL) (French: Licence Art Libre, LAL) is a copyleft license that grants the right to freely copy, distribute, and transform creative works except for computer hardware and software, including for commercial use.
GNU General Public LicenseThe GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses. The GPL is a copyleft license, which means that it guarantees end users the freedom to run, study, share, or modify the software, but if you distribute a derivative work or modification, you must provide the source code to those recipients under the same or equivalent license terms — there is no requirement to publish anything to the public at large.
CopyrightLegal concept regulating rights of a creative workA copyright is a type of intellectual property that gives its owner the exclusive legal right to copy, distribute, adapt, display, and perform a creative work, usually for a limited time. The creative work may be in a literary, artistic, educational, or musical form. Copyright is intended to protect the original expression of an idea in the form of a creative work, but not the idea itself.
PatentleftPatentleft is the practice of licensing patents (especially biological patents) for royalty-free use, on the condition that adopters license related improvements they develop under the same terms. Copyleft-style licensors seek "continuous growth of a universally accessible technology commons" from which they, and others, will benefit.
LicenseA license (American English) or licence (Commonwealth English) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit). A license is granted by a party (licensor) to another party (licensee) as an element of an agreement between those parties. In the case of a license issued by a government, the license is obtained by applying for it.
Source codeIn computing, source code, or simply code or source, is human readableplain text that can eventually result in controlling the behavior of a computer. In order to control a computer, it must be processed by a computer program – either executed directly via an interpreter or translated into a more computer-consumable form such as via a compiler.
ArtArt is a diverse range of cultural activity centered around works utilizing creative or imaginative talents, which are expected to evoke a worthwhile experience, generally through an expression of emotional power, conceptual ideas, technical proficiency, or beauty. There is no generally agreed definition of what constitutes art, and its interpretation has varied greatly throughout history and across cultures.
SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.
