Share-alike
Share-alike (🄎) is a copyright licensing term, originally used by the Creative Commons project, to describe works or licenses that require copies or adaptations of the work to be released under the same or similar license as the original. Copyleft licenses are free content or free software licenses with a share-alike condition. Two currently-supported Creative Commons licenses have the ShareAlike condition: Creative Commons Attribution-ShareAlike (a copyleft, free content license) and Creative Commons Attribution-NonCommercial-ShareAlike (a proprietary license). The term has also been used outside copyright law to refer to a similar plan for patent licensing. Copyleft Copyleft or libre share-alike licenses are the largest subcategory of share-alike licenses. They include both free content licenses like Creative Commons Attribution-ShareAlike and free software licenses like the GNU General Public License. These licenses have been described pejoratively as viral license ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copyleft
Copyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, ''freedoms'' refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, scientific discoveries and even certain patents. Copyleft software licenses are considered ''protective'' or ''reciprocal'' in contrast with permissive free software licenses, and require that information necessary for reproducing and modifying the work must be made available to recipients of the software program, which are often distributed as binary executables. This information is most commonly in the form of source code files, which usually contain a copy of the license terms and acknowledge the autho ...

Public Copyright Licenses
A public license or public copyright licenses is a license by which a copyright holder as licensor can grant additional copyright permissions to any and all persons in the general public as licensees. By applying a public license to a work, provided that the licensees obey the terms and conditions of the license, copyright holders give permission for others to copy or change their work in ways that would otherwise infringe copyright law. Some public licenses, such as the GNU GPL and the CC BY-SA, are also considered free or open copyright licenses. However, other public licenses like the CC BY-NC are not open licenses, because they contain restrictions on commercial or other types of use. Public copyright licenses do not limit their licensees. In other words, any person can take advantage of the license. The former Creative Commons (CC) ''Developing Nations License'' was not a public copyright license, because it limited licensees to those in developing nations. Current Creat ...

Wikimedia Foundation
The Wikimedia Foundation, Inc., or Wikimedia for short and abbreviated as WMF, is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California and registered as a charitable foundation under local laws. Best known as the hosting platform for Wikipedia, a crowdsourced online encyclopedia, it also hosts other related projects and MediaWiki, a wiki software. The Wikimedia Foundation was established in 2003 in St. Petersburg, Florida, by Jimmy Wales as a nonprofit way to fund Wikipedia, Wiktionary, and other crowdsourced wiki projects that had until then been hosted by Bomis, Wales's for-profit company. The Foundation finances itself mainly through millions of small donations from Wikipedia readers, collected through email campaigns and annual fundraising banners placed on Wikipedia and its sister projects. These are complemented by grants from philanthropic organizations and tech companies, and starting in 2022, by services income from Wikimedi ...

Attribution (copyright)
Attribution, in copyright law, is acknowledgment as credit to the copyright holder or author of a work. If a work is under copyright, there is a long tradition of the author requiring attribution while directly quoting portions of work created by that author. An author may formally require attribution required via a license, legally preventing others from claiming to have written the work and allowing a copyright holder to retain reputational benefits from having written it. In cases when the copyright holder is the author themselves, this behavior is often moralized as a sign of decency and respect to acknowledge the creator by giving them credit for the work. This said, a work in the public domain, which is any not covered by copyright, has no such attribution requirement in most parts of the world. This is the distinguishing factor between plagiarism, which is not a crime, but an unethical act, and copyright infringement, which may be a cause of legal action from the author. ...

Free Culture Movement
The free-culture movement is a social movement that promotes the freedom to distribute and modify the creative works of others in the form of free content or open content without compensation to, or the consent of, the work's original creators, by using the Internet and other forms of media. The movement objects to what it considers over-restrictive copyright laws. Many members of the movement argue that such laws hinder creativity. They call this system "permission culture". The free-culture movement, with its ethos of free exchange of ideas, is aligned with the free and open-source-software movement, as well as other movements and philosophies such as open access (OA), the remix culture, the hacker culture, the access to knowledge movement, the copyleft movement and the public domain movement. History Precursors In the late 1960s, Stewart Brand founded the ''Whole Earth Catalog'' and argued that technology could be liberating rather than oppressing.. He coined th ...

Wikipedia Community
The Wikipedia community, collectively known colloquially as Wikipedians, is an informal community that volunteers to create and maintain Wikipedia, an online encyclopedia. Since August 2012, the word "Wikipedian" has been an '' Oxford Dictionary'' entry. Wikipedians may consider themselves part of the Wikimedia movement, a global network of volunteer contributors to Wikipedia and other related projects hosted by the Wikimedia Foundation. Demographics In April 2008, writer and lecturer Clay Shirky and computer scientist Martin Wattenberg estimated the total time spent creating Wikipedia at roughly 100 million hours. In November 2011, there were approximately 31.7 million registered user accounts across all language editions of which around 270,000 were "active" (made at least one edit every month). A study published in 2010 found that the contributor base to Wikipedia "was barely 13% women; the average age of a contributor was in the mid-20s". A 2011 study by researc ...

License Compatibility
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. Proprietary licenses are generally program-specific and incompatible; authors must negotiate to combine code. Copyleft licenses are commonly deliberately incompatible with proprietary licenses, in order to prevent copyleft software from being re-licensed under a proprietary license, turning it into proprietary software. Many copyleft licenses explicitly allow relicensing under some other copyleft licenses. Permissive licenses are (with minor exceptions) compatible with everything, including proprietary licenses; there is thus no guarantee that all derived works will remain under a permissive license. ...

Microsoft Limited Reciprocal License
The Shared Source Initiative (SSI) is a Source-available software, source-available Software license, software licensing scheme launched by Microsoft in May 2001. The program includes a spectrum of technologies and licenses, and most of its source code offerings are available for download after eligibility criteria are met. Overview Microsoft's Shared Source Initiative allows individuals and organizations to access Microsoft's source code for reference (e.g. when developing complementary systems), for review and auditing from a security perspective (mostly wanted by some large corporations and governments), and for development (academic institutions, OEMs, individual developers). As part of the framework, Microsoft released 5 licenses for general use. Two of them, Microsoft Public License and Microsoft Reciprocal License, have been approved by the Open Source Initiative as open source licenses and are regarded by the Free Software Foundation as free software licenses.

Permissive Software License
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. 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."
