Permissive Free Software Licences
A 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 restrictions 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. the most popular free-software license is the permissive MIT license. Comparison table Example The following is the full text of the simple GNU All-permissive License: Definitions The Open Source Initiative defines a permissive software license as a "non-copyleft license that guarantees the freedoms to use, modify and redistribute". GitHub's ''choosealicense'' website describes the permissive MIT license as " ettingpeople do anything they want with your code as long as they provide attribution back to you and don't hold you liable."

Free-software License
A free-software license is a notice that grants the recipient of a piece of software extensive rights to modify and software distribution, redistribute that software. These actions are usually prohibited by copyright law, but the rights-holder (usually the author) of a piece of software can remove these restrictions by accompanying the software with a software license which grants the recipient these rights. Software using such a license is free software (or free and open-source software) as conferred by the copyright holder. Free-software licenses are applied to software in source code and also binary object code, object-code form, as the copyright law recognizes both forms. Comparison Free-software licenses provide risk mitigation against different legal threats or behaviors that are seen as potentially harmful by developers: History Pre-1980s In the early times of software, sharing of software and source code was common in certain communities, for instance academ ...

Copyright
A 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. A copyright is subject to limitations based on public interest considerations, such as the fair use doctrine in the United States and fair dealings doctrine in the United Kingdom. Some jurisdictions require "fixing" copyrighted works in a tangible form. It is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders. These rights normally include reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution. Copyrights can be granted by ...

MIT License
The MIT License is a permissive software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts very few restrictions on reuse and therefore has high license compatibility. Unlike copyleft software licenses, the MIT License also permits reuse within proprietary software, provided that all copies of the software or its substantial portions include a copy of the terms of the MIT License and also a copyright notice. In 2015, the MIT License was the most popular software license on GitHub, and was still the most popular in 2025. Notable projects that use the MIT License include the X Window System, Ruby on Rails, Node.js, Lua (programming language), Lua, jQuery, .NET, Angular (web framework), Angular, and React (JavaScript library), React. License terms The MIT License has the identifier MIT in the SPDX License List. It is also known as the "#Ambiguity and variants, Expat License". It has the following terms: Co ...

CC BY-NC
A Creative Commons NonCommercial license (CC NC, CC BY-NC or NC license) is a Creative Commons license which a copyright holder can apply to their media to give public permission for anyone to reuse that media only for noncommercial activities. Creative Commons is an organization which develops a variety of public copyright licenses, and the "noncommercial" licenses are a subset of these. Unlike the CC0, CC BY, and CC BY-SA licenses, the CC BY-NC license is considered non-free. A challenge with using these licenses is determining what noncommercial use is. Defining "Noncommercial" In September 2009 Creative Commons published a report titled, "Defining 'Noncommercial'". The report featured survey data, analysis, and expert opinions on what "noncommercial" means, how it applied to contemporary media, and how people who share media interpret the term. The report found that in some aspects there was public agreement on the meaning of "noncommercial", but for other aspects, there i ...

Free Art License
The Free Art License (FAL) () 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. History The license was written in July 2000, with contributions from the mailing list [email protected] and, in particular, with French lawyers Mélanie Clément-Fontaine and David Geraud, and French artists Isabelle Vodjdani and Antoine Moreau. It followed meetings held by Copyleft Attitude Antoine Moreau, with the artists gathered around the magazine ''Allotopie'': Francis Deck, Antonio Gallego, Roberto Martinez, and Emma Gall. They took place at "Accès Local" in January 2000 and "Public" in March 2000, two places of contemporary art in Paris. In 2005, Moreau wrote a memoir edited by Liliane Terrier entitled in (Copyleft applied to artistic creation. The Copyleft Attitude collective and the Free Art License). In 2007, version 1.3 of the Free Art License was a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

CC BY-SA
A Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted "work". A CC license is used when an author wants to give other people the right to share, use, and build upon a work that the author has created. CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of a given work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work. There are several types of Creative Commons licenses. Each license differs by several combinations that condition the terms of distribution. They were initially released on December 16, 2002, by Creative Commons, a U.S. non-profit corporation founded in 2001. There have also been five versions of the suite of licenses, numbered 1.0 through 4.0. Released in November ...

Proprietary Software
Proprietary software is computer software, software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms. Proprietary software is a subset of non-free software, a term defined in contrast to free and open-source software; non-commercial licenses such as CC BY-NC are not deemed proprietary, but are non-free. Proprietary software may either be closed-source software or source-available software. Types Origin Until the late 1960s, computers—especially large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than Sales, sold. Service and all software available ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aladdin Free Public License
The Aladdin Free Public License, abbreviated AFPL, is a license written by L. Peter Deutsch for his Ghostscript PostScript language interpreter. History The license was derived from the GNU General Public License, but differs on two key points: * The source code must be included with any software distribution. * The software may not be sold, including any fees involved with distribution. Deutsch chose to include a commercial restriction in the AFPL based on his observation of people including Ghostscript in commercial products without full license compliance. Recent versions of Ghostscript are not licensed under the AFPL. Despite the name, the Free Software Foundation does not consider the AFPL a free software license, neither the OSI consider it an open-source license Open-source licenses are software licenses that allow content to be used, modified, and shared. They facilitate free and open-source software (FOSS) development. Intellectual property (IP) laws restrict t ...
