Free-culture movement

From Wikipedia, the free encyclopedia

The free-culture movement is a social movement that promotes the freedom to distribute and modify creative works in the form of free content[1][2] or open content[3][4][5] by using the Internet and other forms of media.

The movement objects to over-restrictive copyright laws. Many members of the movement argue that such laws hinder creativity.[6] They call this system "permission culture."[7]

Creative Commons is an organization started by Lawrence Lessig which provides licenses that permit sharing and remixing under various conditions, and also offers an online search of various Creative Commons-licensed works.

The free-culture movement, with its ethos of free exchange of ideas, is aligned with the free and open-source-software movement.

Today, the term stands for many other movements, including open access (OA), the remix culture, the hacker culture, the access to knowledge movement, the Open Source Learning, the copyleft movement and the public domain movement.[citation needed]

History

Precursors

In the late 1960s, Stewart Brand founded the Whole Earth Catalog and argued that technology could be liberating rather than oppressing.[8] He coined the slogan Information wants to be free in 1984[9] against limiting access to information by governmental control, preventing a public domain of information.[10]

Background of the formation of the free-culture movement

In 1998, the United States Congress passed the Sonny Bono Copyright Term Extension Act which President Clinton signed into law. The legislation extended copyright protections for twenty additional years, resulting in a total guaranteed copyright term of seventy years after a creator's death. The bill was heavily lobbied by music and film corporations like Disney, and dubbed as the Mickey Mouse Protection Act. Lawrence Lessig claims copyright is an obstacle to cultural production, knowledge sharing and technological innovation, and that private interests – as opposed to public good – determine law.[11] He travelled the country in 1998, giving as many as a hundred speeches a year at college campuses, and sparked the movement. It led to the foundation of the first chapter of the Students for Free Culture at Swarthmore College.

In 1999, Lessig challenged the Bono Act, taking the case to the US Supreme Court. Despite his firm belief in victory, citing the Constitution's plain language about "limited" copyright terms, Lessig only gained two dissenting votes: from Justices Stephen Breyer and John Paul Stevens.

Foundation of the Creative Commons

In 2001, Lessig initiated Creative Commons, an alternative "some rights reserved" licensing system to the default "all rights reserved" copyright system. Lessig focuses on a fair balance between the interest of the public to use and participate into released creative works and the need of protection for a creator's work, which still enables a "read-write" remix culture.[6]

The term “free culture” was originally used since 2003 during the World Summit on Information Society[12] to present the first free license for artistic creation at large, initiated by the Copyleft attitude team in France since 2001 (named free art license). It was then developed in Lawrence Lessig's book Free Culture in 2004.[13]

In August 2003 the Open Content Project, a 1998 Creative Commons precursor by David A. Wiley, announced the Creative Commons as successor project and Wiley joined as director.[14][15]

"Free Cultural Works" Definition

In 2005/2006 within the free-culture movement, Creative Commons has been criticized by Erik Möller[16] and Benjamin Mako Hill for lacking minimum standards for freedom.[17] Following this, the Definition of Free Cultural Works were created as collaborative work of many, including Erik Möller, Lawrence Lessig, Benjamin Mako Hill and Richard Stallman.[18] In February 2008, several Creative Commons licenses were "approved for free cultural works", namely the CC BY and CC BY-SA (later also the CC0).[19] Creative commons licenses with restrictions on commercial use or derivative works were not approved.

In October 2014 the Open Knowledge Foundation described their definition of "open", for open content and open knowledge, as synonymous to the definition of "free" in the "Definition of Free Cultural Works", noting that both are rooted in the Open Source Definition and Free Software Definition.[20] Therefore, the same three creative commons licenses are recommended for open content and free content, CC BY, CC BY-SA, and CC0.[21][22][23] The Open Knowledge foundation defined additionally three specialized licenses for data and databases, previously unavailable, the Open Data Commons Public Domain Dedication and Licence (PDDL), the Open Data Commons Attribution License (ODC-BY) and the Open Data Commons Open Database License (ODbL).

Organizations


The organization commonly associated with free culture is Creative Commons (CC), founded by Lawrence Lessig. CC promotes sharing creative works and diffusing ideas to produce cultural vibrance, scientific progress and business innovation.

Student organization FreeCulture.org, inspired by Lessig and founded 2003. The Building blocks are a symbol for reuse and remixing of creative works, used also as symbol of the Remix culture.

QuestionCopyright.org is another organization whose stated mission is "to highlight the economic, artistic, and social harm caused by distribution monopolies, and to demonstrate how freedom-based distribution is better for artists and audiences."[24] QuestionCopyright may be best known for its association with artist Nina Paley, whose multi-award-winning feature length animation Sita Sings The Blues has been held up as an extraordinarily successful[25] example of free distribution under the aegis of the "Sita Distribution Project".[26] The web site of the organization has a number of resources, publications, and other references related to various copyright, patent, and trademark issues.

The student organization Students for Free Culture is sometimes confusingly called "the Free Culture Movement," but that is not its official name. The organization is a subset of the greater movement. The first chapter was founded in 1998 at Swarthmore College, and by 2008, the organization had twenty-six chapters.[27]

The free-culture movement takes the ideals of the free and open source software movement and extends them from the field of software to all cultural and creative works. Early in Creative Commons' life, Richard Stallman (the founder of the Free Software Foundation and the free software movement) supported the organization. He withdrew his support due to the introduction of several licenses including a developing nations and the sampling licenses[28] and later restored some support when Creative Commons retired those licenses.

The free music movement, a subset of the free-culture movement, started out just as the Web rose in popularity with the Free Music Philosophy[29] by Ram Samudrala in early 1994. It was also based on the idea of free software by Richard Stallman and coincided with nascent open art and open information movements (referred to here as collectively as the "free-culture movement"). The Free Music Philosophy used a three pronged approach to voluntarily encourage the spread of unrestricted copying, based on the fact that copies of recordings and compositions could be made and distributed with complete accuracy and ease via the Internet. The subsequent free music movement was reported on by diverse media outlets including Billboard,[30] Forbes,[31] Levi's Original Music Magazine,[32] The Free Radical,[33] Wired[34][35] and The New York Times.[36] Along with the explosion of the Web driven by open source software and Linux, the rise of P2P and lossy compression, and despite the efforts of the music industry, free music became largely a reality in the early 21st century.[37] Organizations such as the Electronic Frontier Foundation and Creative Commons with free information champions like Lawrence Lessig were devising numerous licenses that offered different flavors of copyright and copyleft. The question was no longer why and how music should be free, but rather how creativity would flourish while musicians developed models to generate revenue in the Internet era.[38][39][40]

Reception

Skepticism from the FSF

Initially, Free Software Foundation founder Richard Stallman did not see the importance of free works beyond software.[41] For instance for manuals and books Stallman stated in the 1990s:
As a general rule, I don't believe that it is essential for people to have permission to modify all sorts of articles and books. The issues for writings are not necessarily the same as those for software. For example, I don't think you or I are obliged to give permission to modify articles like this one, which describe our actions and our views.
Similarly, in 1999 Stallman said that he sees "no social imperative for free hardware designs like the imperative for free software".[42] Other authors, such as Joshua Pearce, have argued that there is an ethical imperative for open-source hardware, specifically with respect to open-source-appropriate technology for sustainable development.[43]

Later, Stallman changed his position slightly and advocated for free sharing of information in 2009.[44] But, in 2011 Stallman commented on the Megaupload founder's arrest, "I think all works meant for practical uses must be free, but that does not apply to music, since music is meant for appreciation, not for practical use."[45] In a follow up Stallman differentiated three classes: Works of practical use should be free, Works representing points of view should be shareable but not changeable and works of art or entertainment should be copyrighted (but only for 10 years).[46] In an essay in 2012 Stallman argued that video games as software should be free but not their artwork.[47] In 2015 Stallman advocated for free hardware designs.[48]

Copyright proponents

Vocal criticism against the free-culture movement comes from copyright proponents.

Prominent technologist and musician Jaron Lanier discusses this perspective of Free Culture in his 2010 book You Are Not a Gadget. Lanier's concerns include the depersonalization of crowd-sourced anonymous media (such as Wikipedia) and the economic dignity of middle-class creative artists.

Andrew Keen, a critic of Web 2.0, criticizes some of the Free Culture ideas in his book, Cult of the Amateur, describing Lessig as an "intellectual property communist."[49]

The decline of news media industry's market share is blamed on free culture but scholars like Clay Shirky claim that the market itself, not free culture, is what's killing the journalism industry.[13]

Free software movement

From Wikipedia, the free encyclopedia

Richard Stallman circa 2002, founder of the GNU Project and the free software movement.

The free software movement (FSM) or free / open source software movement (FOSSM) or free / libre open source software (FLOSS) is a social movement[1] with the goal of obtaining and guaranteeing certain freedoms for software users, namely the freedom to run the software, to study and change the software, and to redistribute copies with or without changes. Although drawing on traditions and philosophies among members of the 1970s hacker culture and academia, Richard Stallman formally founded the movement in 1983 by launching the GNU Project.[2] Stallman later established the Free Software Foundation in 1985 to support the movement.

Philosophy

The philosophy of the movement is that the use of computers should not lead to people being prevented from cooperating with each other. In practice, this means rejecting "proprietary software", which imposes such restrictions, and promoting free software,[3] with the ultimate goal of liberating everyone in cyberspace[4] – that is, every computer user. Stallman notes that this action will promote rather than hinder the progression of technology, since "it means that much wasteful duplication of system programming effort will be avoided. This effort can go instead into advancing the state of the art".[5]

Members of the free software movement believe that all users of software should have the freedoms listed in The Free Software Definition. Many of them hold that it is immoral to prohibit or prevent people from exercising these freedoms and that these freedoms are required to create a decent society where software users can help each other, and to have control over their computers.[6]

Some free software users and programmers do not believe that proprietary software is strictly immoral, citing an increased profitability in the business models available for proprietary software or technical features and convenience as their reasons.[7]

"While social change may occur as an unintended by-product of technological change, advocates of new technologies often have promoted them as instruments of positive social change." This quote by San Jose State professor Joel West explains much of the philosophy, or the reason that the free source movement is alive. If it is assumed that social change is not only affected, but in some points of view, directed by the advancement of technology, is it ethical to hold these technologies from certain people? If not to make a direct change, this movement is in place to raise awareness about the effects that take place because of the physical things around us. A computer, for instance, allows us so many more freedoms than we have without a computer, but should these technological mediums be implied freedoms, or selective privileges? The debate over the morality of both sides to the free software movement is a difficult topic to compromise respective opposition.[8]

The Free Software Foundation also believes all software needs free documentation, in particular because conscientious programmers should be able to update manuals to reflect modification that they made to the software, but deems the freedom to modify less important for other types of written works.[9] Within the free software movement, the FLOSS Manuals foundation specialises on the goal of providing such documentation. Members of the free software movement advocate that works which serve a practical purpose should also be free.[10]

Writing and spreading free software

The core work of the free software movement focused on software development. The free software movement also rejects proprietary software, refusing to install software that does not give them the freedoms of free software. According to Stallman, "The only thing in the software field that is worse than an unauthorised copy of a proprietary program, is an authorised copy of the proprietary program because this does the same harm to its whole community of users, and in addition, usually the developer, the perpetrator of this evil, profits from it."[11]

Building awareness

Some supporters of the free software movement take up public speaking, or host a stall at software-related conferences to raise awareness of software freedom. This is seen as important since people who receive free software, but who are not aware that it is free software, will later accept a non-free replacement or will add software that is not free software.[12]

Ethical equality

Margaret S. Elliot, a researcher in the Institute for Software at the University of California Irvine, not only outlines many benefits that could come from a free software movement, she claims that it is inherently necessary to give every person equal opportunity to utilize the Internet, assuming that the computer is globally accessible. Since the world has become more based in the framework of technology and its advancement, creating a selective internet that allows only some to surf the web freely is nonsensical according to Elliot. If there is a desire to live in a more coexistent world that is benefited by communication and global assistance, then globally free software should be a position to strive for, according to many scholars who promote awareness about the free software movement. The ideas sparked by the GNU associates are an attempt to promote a "cooperative environment" that understands the benefits of having a local community and a global community.[13]

Legislation

A lot of lobbying work has been done against software patents and expansions of copyright law. Other lobbying focusses directly on use of free software by government agencies and government-funded projects.

The Venezuelan government implemented a free software law in January 2006. Decree No. 3,390 mandated all government agencies to migrate to free software over a two-year period.[14]

Congressmen Edgar David Villanueva and Jacques Rodrich Ackerman have been instrumental in introducing free software in Peru, with bill 1609 on "Free Software in Public Administration".[15] The incident invited the attention of Microsoft Inc, Peru, whose general manager wrote a letter to Villanueva. His response received worldwide attention and is seen as a classic piece of argumentation favouring use of free software in governments.[16]

In the United States, there have been efforts to pass legislation at the state level encouraging use of free software by state government agencies.[17]

Subgroups and schisms

Like many social movements, the free software movement has ongoing internal conflict between the many FOSS organizations (FSF, OSI, Debian, Mozilla Foundation, Apache Foundation etc.) and their personalities. For instance there is disagreement about the amount of compromises and pragmatism needed versus the need for strict adherence to values.[18]

Open source

Although commercial free software was not uncommon at the time (see Cygnus Solutions for example), in 1998 after an announcement that Netscape would liberate their popular Web browser, a strategy session was held to develop a stronger business case for free software which would focus on technology rather than politics.[19] After this, Eric Raymond and Bruce Perens founded the Open Source Initiative (OSI) to promote the term "open source software" as an alternative term for free software. OSI wanted to address the perceived shortcomings in ambiguous "free software" term,[20][21][22] and some members of OSI in addition didn't follow the free software movement's focus on non-free software as a social and ethical problem; but instead focused on the advantages of open source as superior model for software development.[23] The latter became the view of people like Eric Raymond and Linus Torvalds, while Bruce Perens argues that open source was simply meant to popularize free software under a new brand, and even called for a return to the basic ethical principles.[24]
Some free software advocates use the term free and open source software (FOSS) as an inclusive compromise, drawing on both philosophies to bring both free software advocates and open-source software advocates together to work on projects with more cohesion. Some users believe that a compromise term encompassing both aspects is ideal, to promote both the user's freedom with the software and also to promote the perceived superiority of an open-source-development model. This eclectic view is reinforced by the fact that the overwhelming majority of OSI-approved licenses and self-avowed open-source programs are also compatible with the free software formalisms and vice versa.[10]

While some people prefer to link the two ideas of "open-source software" and "free software" together, they offer two separate ideas and values. This ambiguity began in 1998 when people started to use the term "open-source software" rather than "free software". People in the community of free software used these separate terms as a way to differentiate what they did. Richard Stallman has called open source "a non-movement", because it "does not campaign for anything".[25] Open source addresses software being open as a practical question as opposed to an ethical dilemma. In other words, it focuses more on the development. The open-source movement ultimately determines that non-free software is not the solution of best interest but nonetheless a solution.[26][10]

On the other hand, the free software movement views free software as a moral imperative: that proprietary software should be rejected for selfish and social reasons, and that only free software should be developed and taught to cope with the task of making computing technology beneficial to humanity. It is argued that whatever economical or technical merits free software may have, those are byproducts stemming from the rights that free software developers and users must enjoy. An example of this would be the unlikelihood of free software being designed to mistreat or spy on users.[27] At the same time, the benefits purveyed by the open-source movement have been challenged both from inside and outside the free software movement. It is unclear whether free and open-source software actually leads to more performant and less vulnerable code, with researchers Robert Glass and Benjamin Mako Hill providing statistical insight that this is usually not the case.[28][29]

Regarding the meaning and misunderstandings of the word free, those who work within the free software camp have searched for less ambiguous terms and analogies like "free beer vs free speech" in efforts to convey the intended semantics, so that there is no confusion concerning the profitability of free software. The loan adjective libre has gained some traction in the English-speaking free software movement as unequivocally conveying the state of being in freedom that free software refers to. This is not considered schismatic; libre is seen as an alternative explanatory device. In fact, free software has always been unambiguously referred to as "libre software" (in translation) in languages where the word libre or a cognate is native. In India, where free software has gained a lot of ground,[30] the unambiguous term swatantra and its variants are widely used instead of "free".[31][32]

The free software movement rebuts that while "free" may be prone to confuse novices because of the duplicity of meanings, at least one of the meanings is completely accurate, and that it is hard to get it wrong once the difference has been learned. It is also ironically noted that "open source" isn't exempt of poor semantics either, as a misunderstanding arise whereby people think source code disclosure is enough to meet the open-source criteria, when in fact it is not.[10]

The switch from the free software movement to the open-source movement has had negative effects on the progression of community, according to Christopher Kelty who dedicates a scholarly chapter to the free software movements in "Theorizing Media and Practice". The open-source movement denies that selectivity and the privatization of software is unethical. Although the open-source movement is working towards the same social benefits as the free software movement, Kelty claims that by disregarding this fundamental belief of the free software advocates, one is destroying the overall argument. If it can be claimed that it is ethical to limit the internet and other technology to only users who have the means to use this software, then there is no argument against the way things are at the moment; there is no need to complain if all morality is in effect.[33]

Although the movements have separate values and goals, people in both the open-source community and free software community collaborate when it comes to practical projects.[34] By 2005, Richard Glass considered the differences to be a "serious fracture" but "vitally important to those on both sides of the fracture" and "of little importance to anyone else studying the movement from a software engineering perspective" since they have had "little effect on the field".[35]

Stallman and Torvalds

The two most prominent people associated with the movement, Richard Stallman and Linus Torvalds, may be seen as representatives of the value based versus apolitical philosophies, as well as the GNU versus Linux coding styles. In the GNU/Linux naming controversy the FSF argues for the term GNU/Linux because GNU was a longstanding project to develop a free operating system, of which they assert the kernel was the last missing piece.[36]

Criticism and controversy

Should principles be compromised?

Eric Raymond criticises the speed at which the free software movement is progressing, suggesting that temporary compromises should be made for long-term gains. Raymond argues that this could raise awareness of the software and thus increase the free software movement's influence on relevant standards and legislation.[37]

Richard Stallman, on the other hand, sees the current level of compromise as a greater cause for worry.[18][38][39]

How will programmers get paid?

Stallman said that this is where people get the misconception of "free": there is no wrong in programmers' requesting payment for a proposed project. Restricting and controlling the user's decisions on use is the actual violation of freedom. Stallman defends that in some cases, monetary incentive is not necessary for motivation since the pleasure in expressing creativity is a reward in itself.[5] On the other hand, Stallman admits that is not easy to raise money for FOSS software projects.[40]

"Viral" licensing

The free software movement champions copyleft licensing schema (often pejoratively called "viral licenses"). In its strongest form, copyleft mandates that any works derived from copyleft-licensed software must also carry a copyleft license, so the license spreads from work to work like a computer virus might spread from machine to machine. These licensing terms can only be enforced through asserting copyrights.[41] Critics of copyleft licensing challenge the idea that restricting modifications is in line with the free software movement's emphasis on various "freedoms," especially when alternatives like MIT, BSD, and Apache licenses are more permissive.[42][43] Proponents enjoy the assurance that copylefted work cannot usually be incorporated into non-free software projects.[44] They emphasize that copyleft licenses may not attach for all uses and that in any case, developers can simply choose not to use copyleft-licensed software.[45][46]

License proliferation and compatibility

FOSS license proliferation is a serious concern in the FOSS domain due to increased complexity of license compatibility considerations which limits and complicates source code reuse between FOSS projects.[47] The OSI and the FSF maintain own lists of dozens of existing and acceptable FOSS licenses.[48] There is an agreement among most that the creation of new licenses should be minimized at all cost and these created should be made compatible with the major existing FOSS licenses. Therefore, there was a strong controversy around the update of the GPlv2 to the GPLv3 in 2007,[49][50] as the updated license is not compatible with the previous version.[51][52][53] Several projects (mostly of the open source faction[50] like the Linux kernel[54][55]) decided to not adopt the GPLv3 while the GNU projects adopted the GPLv3.

Open-source model

From Wikipedia, the free encyclopedia

The open-source model is a decentralized software-development model that encourages open collaboration.[1][2] A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology,[3] and open-source drug discovery.[4][5]

Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint.[6][7] Before the phrase open source became widely adopted, developers and producers used a variety of other terms. Open source gained hold with the rise of the Internet.[8] The open-source software movement arose to clarify copyright, licensing, domain, and consumer issues.

Generally, open source refers to a computer program in which the source code is available to the general public for use or modification from its original design. Open-source code is meant to be a collaborative effort, where programmers improve upon the source code and share the changes within the community. Code is released under the terms of a software license. Depending on the license terms, others may then download, modify, and publish their version (fork) back to the community.

Many large formal institutions have sprung up to support the development of the open-source movement, including the Apache Software Foundation, which supports community projects such as the open-source framework Apache Hadoop and the open-source HTTP server Apache HTTP.

History

The sharing of technical information predates the Internet and the personal computer considerably. For instance, in the early years of automobile development a group of capital monopolists owned the rights to a 2-cycle gasoline-engine patent originally filed by George B. Selden.[9] By controlling this patent, they were able to monopolize the industry and force car manufacturers to adhere to their demands, or risk a lawsuit.

In 1911, independent automaker Henry Ford won a challenge to the Selden patent. The result was that the Selden patent became virtually worthless and a new association (which would eventually become the Motor Vehicle Manufacturers Association) was formed.[9] The new association instituted a cross-licensing agreement among all US automotive manufacturers: although each company would develop technology and file patents, these patents were shared openly and without the exchange of money among all the manufacturers.[9] By the time the US entered World War II, 92 Ford patents and 515 patents from other companies were being shared among these manufacturers, without any exchange of money (or lawsuits).[9]

Early instances of the free sharing of source code include IBM's source releases of its operating systems and other programs in the 1950s and 1960s, and the SHARE user group that formed to facilitate the exchange of software.[10][11] Beginning in the 1960s, ARPANET researchers used an open "Request for Comments" (RFC) process to encourage feedback in early telecommunication network protocols. This led to the birth of the early Internet in 1969.

The sharing of source code on the Internet began when the Internet was relatively primitive, with software distributed via UUCP, Usenet, IRC, and Gopher. BSD, for example, was first widely distributed by posts to comp.os.linux on the Usenet, which is also where its development was discussed. Linux followed in this model.

Open source as a term

The term "open source" was first proposed by a group of people in the free software movement who were critical of the political agenda and moral philosophy implied in the term "free software" and sought to reframe the discourse to reflect a more commercially minded position.[12] In addition, the ambiguity of the term "free software" was seen as discouraging business adoption.[13][14] The group included Christine Peterson, Todd Anderson, Larry Augustin, Jon Hall, Sam Ockman, Michael Tiemann and Eric S. Raymond. Peterson suggested "open source" at a meeting[15] held at Palo Alto, California, in reaction to Netscape's announcement in January 1998 of a source code release for Navigator. Linus Torvalds gave his support the following day, and Phil Hughes backed the term in Linux Journal. Richard Stallman, the founder of the free software movement, initially seemed to adopt the term, but later changed his mind.[15][16] Netscape released its source code under the Netscape Public License and later under the Mozilla Public License.[17]

Raymond was especially active in the effort to popularize the new term. He made the first public call to the free software community to adopt it in February 1998.[18] Shortly after, he founded The Open Source Initiative in collaboration with Bruce Perens.[15]

The term gained further visibility through an event organized in April 1998 by technology publisher Tim O'Reilly. Originally titled the "Freeware Summit" and later known as the "Open Source Summit",[19] the event was attended by the leaders of many of the most important free and open-source projects, including Linus Torvalds, Larry Wall, Brian Behlendorf, Eric Allman, Guido van Rossum, Michael Tiemann, Paul Vixie, Jamie Zawinski, and Eric Raymond. At that meeting, alternatives to the term "free software" were discussed. Tiemann argued for "sourceware" as a new term, while Raymond argued for "open source". The assembled developers took a vote, and the winner was announced at a press conference the same evening.[19]

"Open source" has never managed to entirely supersede the older term "free software", giving rise to the combined term free and open-source software (FOSS).

Economics

Some economists agree that open-source is an information good[20] or "knowledge good" with original work involving a significant amount of time, money, and effort. The cost of reproducing the work is low enough that additional users may be added at zero or near zero cost – this is referred to as the marginal cost of a product. Copyright creates a monopoly so the price charged to consumers can be significantly higher than the marginal cost of production. This allows the author to recoup the cost of making the original work. Copyright thus creates access costs for consumers who value the work more than the marginal cost but less than the initial production cost. Access costs also pose problems for authors who wish to create a derivative work—such as a copy of a software program modified to fix a bug or add a feature, or a remix of a song—but are unable or unwilling to pay the copyright holder for the right to do so.

Being organized as effectively a "consumers' cooperative", open source eliminates some of the access costs of consumers and creators of derivative works by reducing the restrictions of copyright. Basic economic theory predicts that lower costs would lead to higher consumption and also more frequent creation of derivative works. Organizations such as Creative Commons host websites where individuals can file for alternative "licenses", or levels of restriction, for their works.[21] These self-made protections free the general society of the costs of policing copyright infringement.

Others argue that since consumers do not pay for their copies, creators are unable to recoup the initial cost of production and thus have little economic incentive to create in the first place. By this argument, consumers would lose out because some of the goods they would otherwise purchase would not be available. In practice, content producers can choose whether to adopt a proprietary license and charge for copies, or an open license. Some goods which require large amounts of professional research and development, such as the pharmaceutical industry (which depends largely on patents, not copyright for intellectual property protection) are almost exclusively proprietary, although increasingly sophisticated technologies are being developed on open-source principles.[22]

There is evidence that open-source development creates enormous value.[23] For example, in the context of open-source hardware design, digital designs are shared for free and anyone with access to digital manufacturing technologies (e.g. RepRap 3D printers) can replicate the product for the cost of materials.[24] The original sharer may receive feedback and potentially improvements on the original design from the peer production community.

Licensing alternatives

Alternative arrangements have also been shown to result in good creation outside of the proprietary license model. Examples include:[citation needed]


  • Wikipedia is an example of a global application of the open source model.
    Creation for its own sake – For example, Wikipedia editors add content for recreation. Artists have a drive to create. Both communities benefit from free starting material.
  • Voluntary after-the-fact donations – used by shareware, street performers, and public broadcasting in the United States.[citation needed]
  • Patron – For example, open access publishing relies on institutional and government funding of research faculty, who also have a professional incentive to publish for reputation and career advancement. Works of the U.S. federal government are automatically released into the public domain.[citation needed]
  • Freemium – Give away a limited version for free and charge for a premium version (potentially using a dual license).
  • Give away the product and charge something related – Charge for support of open-source enterprise software, give away music but charge for concert admission.[citation needed]
  • Give away work in order to gain market share – Used by artists, in corporate software to spoil a dominant competitor (for example in the browser wars and the Android operating system).[citation needed]
  • For own use – Businesses or individual software developers often create software to solve a problem, bearing the full cost of initial creation. They will then open source the solution, and benefit from the improvements others make for their own needs. Communalizing the maintenance burden distributes the cost across more users; free riders can also benefit without undermining the creation process.

Open-source applications


Open-source model application domains

Social and political views have been affected by the growth of the concept of open source. Advocates in one field often support the expansion of open source in other fields. But Eric Raymond and other founders of the open-source movement have sometimes publicly argued against speculation about applications outside software, saying that strong arguments for software openness should not be weakened by overreaching into areas where the story may be less compelling. The broader impact of the open-source movement, and the extent of its role in the development of new information sharing procedures, remain to be seen.

The open-source movement has inspired increased transparency and liberty in biotechnology research, for example by open therapeutics and CAMBIA[25] Even the research methodologies themselves can benefit from the application of open-source principles.[26] It has also given rise to the rapidly-expanding open-source hardware movement.

Computer software


Blender is an open-source 3D graphics editor.

Android, the most popular mobile operating system (as of Nov 2012)[27]
Open-source software is software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees.[28] Open-source code can evolve through community cooperation. These communities are composed of individual programmers as well as large companies. Some of the individual programmers who start an open-source project may end up establishing companies offering products or services incorporating open-source programs.[citation needed] Examples of open-source software products are:[29]

Electronics



Open-source hardware is hardware whose initial specification, usually in a software format, are published and made available to the public, enabling anyone to copy, modify and redistribute the hardware and source code without paying royalties or fees. Open-source hardware evolves through community cooperation. These communities are composed of individual hardware/software developers, hobbyists, as well as very large companies. Examples of open-source hardware initiatives are:
  • Openmoko: a family of open-source mobile phones, including the hardware specification and the operating system.
  • OpenRISC: an open-source microprocessor family, with architecture specification licensed under GNU GPL and implementation under LGPL.
  • Sun Microsystems's OpenSPARC T1 Multicore processor. Sun has released it under GPL.[30]
  • Arduino, a microcontroller platform for hobbyists, artists and designers.[31]
  • GizmoSphere, an open-source development platform for the embedded design community; the site includes code downloads and hardware schematics along with free user guides, spec sheets and other documentation.[32]
  • Simputer, an open hardware handheld computer, designed in India for use in environments where computing devices such as personal computers are deemed inappropriate.[33]
  • LEON: A family of open-source microprocessors distributed in a library with peripheral IP cores, open SPARC V8 specification, implementation available under GNU GPL.
  • Tinkerforge: A system of open-source stackable microcontroller building blocks. Allows control of motors and read out sensors with the programming languages C, C++, C#, Object Pascal, Java, PHP, Python and Ruby over a USB or Wifi connection on Windows, Linux and Mac OS X. All of the hardware is licensed under CERN OHL (CERN Open Hardware License).
  • Open Compute Project: designs for computer data center including power supply, Intel motherboard, AMD motherboard, chassis, racks, battery cabinet, and aspects of electrical and mechanical design.[34]
  • Lasersaur, an open-source laser cutter.[35]

Food and beverages



Barack Obama and Dakota Meyer drinking White House Honey Ale in 2011. The recipe is available for free.
Some publishers of open-access journals have argued that data from food science and gastronomy studies should be freely available to aid reproducibility.[36] A number of people have published creative commons licensed recipe books.[37]
  • Open-source colas – cola soft drinks, similar to Coca-Cola and Pepsi, whose recipe is open source and developed by volunteers. The taste is said to be comparable to that of the standard beverages. Most corporations producing beverages hold their formulas as closely guarded secrets.[38]
  • Free Beer (originally Vores Øl) – is an open-source beer created by students at the IT-University in Copenhagen together with Superflex, an artist collective, to illustrate how open-source concepts might be applied outside the digital world.[39][40][41]
  • In 2002, the beer company Brewtopia in Australia started an open-source brewery and invited the general population to be involved in the development and ownership of the brewery, and to vote on the development of every aspect of its beer, Blowfly, and its road to market. In return for their feedback and input, individuals received shares in the company, which is now publicly traded on a stock exchange in Australia. The company has always adhered to its open-source roots and is the only beer company in the world that allows the public to design, customise and develop its own beers online.[42]

Digital content


  • Open-content projects organized by the Wikimedia Foundation – Sites such as Wikipedia and Wiktionary have embraced the open-content Creative Commons content licenses. These licenses were designed to adhere to principles similar to various open-source software development licenses. Many of these licenses ensure that content remains free for re-use, that source documents are made readily available to interested parties, and that changes to content are accepted easily back into the system. Important sites embracing open-source-like ideals are Project Gutenberg[43] and Wikisource, both of which post many books on which the copyright has expired and are thus in the public domain, ensuring that anyone has free, unlimited access to that content.

Medicine

  • Pharmaceuticals – There have been several proposals for open-source pharmaceutical development,[45][46] which led to the establishment of the Tropical Disease Initiative[47] and the Open Source Drug Discovery for Malaria Consortium.[48]
  • Genomics – The term "open-source genomics" refers to the combination of rapid release of sequence data (especially raw reads) and crowdsourced analyses from bioinformaticians around the world that characterised the analysis of the 2011 E. coli O104:H4 outbreak.[49]
  • OpenEMR – OpenEMR is an ONC-ATB Ambulatory EHR 2011-2012 certified electronic health records and medical practice management application. It features fully integrated electronic health, records, practice management, scheduling, electronic billing, and is the base for many EHR programs. http://www.open-emr.org/

Science and engineering


  • Research – The Science Commons was created as an alternative to the expensive legal costs of sharing and reusing scientific works in journals etc.[50]
  • Research – The Open Source Science Project was created to increase the ability for students to participate in the research process by providing them access to microfunding – which, in turn, offers non-researchers the opportunity to directly invest, and follow, cutting-edge scientific research. All data and methodology is subsequently published in an openly accessible manner under a Creative Commons fair use license.
  • Research – The Open Solar Outdoors Test Field (OSOTF)[51] is a grid-connected photovoltaic test system, which continuously monitors the output of a number of photovoltaic modules and correlates their performance to a long list of highly accurate meteorological readings. The OSOTF is organized under open-source principles – All data and analysis is to be made freely available to the entire photovoltaic community and the general public.[51][52]
  • Engineering – Hyperloop, a form of high-speed transport proposed by entrepreneur Elon Musk, which he describes as "an elevated, reduced-pressure tube that contains pressurized capsules driven within the tube by a number of linear electric motors".[53]
  • Construction – WikiHouse is an open-source project for designing and building houses.[54][55]
  • Energy research - The Open Energy Modelling Initiative promotes open-source models and open data in energy research and policy advice.

Robotics

An open-source robot is a robot whose blueprints, schematics, or source code are released under an open-source model.

Transport

  • Open Trip Planner - this code base is growing rapidly, with adoption in Portland, New York, The Netherlands and Helsinki.
  • TravelSpirit – a greater level of 'super-architecture' ambition, to bring a range of open source projects together, in order to deliver 'Mobility as a Service'

Fashion

  • Eyewear – In June 2013, an open-source eyewear brand, Botho, has started trading under the UK based Open Optics Ltd company.[56]

Other


VIA OpenBook is an open-source hardware laptop reference design.
  • Open-source principles can be applied to technical areas such as digital communication protocols and data storage formats.
  • Open design – which involves applying open-source methodologies to the design of artifacts and systems in the physical world. It is very nascent but has huge potential.[57]
  • Open-source-appropriate technology (OSAT) refers to technologies that are designed in the same fashion as free and open-source software.[58] These technologies must be "appropriate technology" (AT) – meaning technology that is designed with special consideration to the environmental, ethical, cultural, social, political, and economic aspects of the community it is intended for. An example of this application is the use of open-source 3D printers like the RepRap to manufacture appropriate technology.[59]
  • Teaching – which involves applying the concepts of open source to instruction using a shared web space as a platform to improve upon learning, organizational, and management challenges. An example of an Open-source courseware is the Java Education & Development Initiative (JEDI).[60] Other examples include Khan Academy and wikiversity. At the university level, the use of open-source-appropriate technology classroom projects has been shown to be successful in forging the connection between science/engineering and social benefit:[61] This approach has the potential to use university students' access to resources and testing equipment in furthering the development of appropriate technology. Similarly OSAT has been used as a tool for improving service learning.[62][63]
  • There are few examples of business information (methodologies, advice, guidance, practices) using the open-source model, although this is another case where the potential is enormous. ITIL is close to open source. It uses the Cathedral model (no mechanism exists for user contribution) and the content must be bought for a fee that is small by business consulting standards (hundreds of British pounds). Various checklists are published by government, banks or accounting firms.
  • An open-source group emerged in 2012 that is attempting to design a firearm that may be downloaded from the internet and "printed" on a 3D Printer.[64] Calling itself Defense Distributed, the group wants to facilitate "a working plastic gun that could be downloaded and reproduced by anybody with a 3D printer".[65]
  • Agrecol, a German NGO has developed an open-source licence for seeds operating with copyleft and created OpenSourceSeeds as a respective service provider. Breeders that apply the license to their new invented material prevent it from the threat of privatisation and help to establish a commons-based breeding sector as an alternative to the commercial sector.[66]

Society and culture

The rise of open-source culture in the 20th century resulted from a growing tension between creative practices that involve require access to content that is often copyrighted, and restrictive intellectual property laws and policies governing access to copyrighted content. The two main ways in which intellectual property laws became more restrictive in the 20th century were extensions to the term of copyright (particularly in the United States) and penalties, such as those articulated in the Digital Millennium Copyright Act (DMCA), placed on attempts to circumvent anti-piracy technologies.[67]

Although artistic appropriation is often permitted under fair-use doctrines, the complexity and ambiguity of these doctrines creates an atmosphere of uncertainty among cultural practitioners. Also, the protective actions of copyright owners create what some call a "chilling effect" among cultural practitioners.[68]

The idea of an "open-source" culture runs parallel to "Free Culture," but is substantively different. Free culture is a term derived from the free software movement, and in contrast to that vision of culture, proponents of open-source culture (OSC) maintain that some intellectual property law needs to exist to protect cultural producers. Yet they propose a more nuanced position than corporations have traditionally sought. Instead of seeing intellectual property law as an expression of instrumental rules intended to uphold either natural rights or desirable outcomes, an argument for OSC takes into account diverse goods (as in "the Good life") and ends.

Sites such as ccMixter offer up free web space for anyone willing to license their work under a Creative Commons license. The resulting cultural product is then available to download free (generally accessible) to anyone with an Internet connection.[69] Older analog technologies such as the telephone or television have limitations on the kind of interaction users can have.

Through various technologies such as peer-to-peer networks and blogs, cultural producers can take advantage of vast social networks to distribute their products. As opposed to traditional media distribution, redistributing digital media on the Internet can be virtually costless. Technologies such as BitTorrent and Gnutella take advantage of various characteristics of the Internet protocol (TCP/IP) in an attempt to totally decentralize file distribution.

Government

  • Open politics (sometimes known as Open-source politics) is a political process that uses Internet technologies such as blogs, email and polling to provide for a rapid feedback mechanism between political organizations and their supporters. There is also an alternative conception of the term Open-source politics which relates to the development of public policy under a set of rules and processes similar to the open-source software movement.
  • Open-source governance is similar to open-source politics, but it applies more to the democratic process and promotes the freedom of information.
  • The South Korean government wants to increase its use of free and open-source software, in order to decrease its dependence on proprietary software solutions. It plans to make open standards a requirement, to allow the government to choose between multiple operating systems and web browsers. Korea's Ministry of Science, ICT & Future Planning is also preparing ten pilots on using open-source software distributions.[70]

Ethics

Open-source ethics is split into two strands:
  • Open-source ethics as an ethical school – Charles Ess and David Berry are researching whether ethics can learn anything from an open-source approach. Ess famously even defined the AoIR Research Guidelines as an example of open-source ethics.[71]
  • Open-source ethics as a professional body of rules – This is based principally on the computer ethics school, studying the questions of ethics and professionalism in the computer industry in general and software development in particular.[72]

Religion

Irish philosopher Richard Kearney has used the term "open-source Hinduism" to refer to the way historical figures such as Mohandas Gandhi and Swami Vivekananda worked upon this ancient tradition.[73]

Media

Open-source journalism formerly referred to the standard journalistic techniques of news gathering and fact checking, reflecting open-source intelligence a similar term used in military intelligence circles. Now, open-source journalism commonly refers to forms of innovative publishing of online journalism, rather than the sourcing of news stories by a professional journalist. In the 25 December 2006 issue of TIME magazine this is referred to as user created content and listed alongside more traditional open-source projects such as OpenSolaris and Linux.

Weblogs, or blogs, are another significant platform for open-source culture. Blogs consist of periodic, reverse chronologically ordered posts, using a technology that makes webpages easily updatable with no understanding of design, code, or file transfer required. While corporations, political campaigns and other formal institutions have begun using these tools to distribute information, many blogs are used by individuals for personal expression, political organizing, and socializing. Some, such as LiveJournal or WordPress, utilize open-source software that is open to the public and can be modified by users to fit their own tastes. Whether the code is open or not, this format represents a nimble tool for people to borrow and re-present culture; whereas traditional websites made the illegal reproduction of culture difficult to regulate, the mutability of blogs makes "open sourcing" even more uncontrollable since it allows a larger portion of the population to replicate material more quickly in the public sphere.

Messageboards are another platform for open-source culture. Messageboards (also known as discussion boards or forums), are places online where people with similar interests can congregate and post messages for the community to read and respond to. Messageboards sometimes have moderators who enforce community standards of etiquette such as banning users who are spammers. Other common board features are private messages (where users can send messages to one another) as well as chat (a way to have a real time conversation online) and image uploading. Some messageboards use phpBB, which is a free open-source package. Where blogs are more about individual expression and tend to revolve around their authors, messageboards are about creating a conversation amongst its users where information can be shared freely and quickly. Messageboards are a way to remove intermediaries from everyday life—for instance, instead of relying on commercials and other forms of advertising, one can ask other users for frank reviews of a product, movie or CD. By removing the cultural middlemen, messageboards help speed the flow of information and exchange of ideas.

OpenDocument is an open document file format for saving and exchanging editable office documents such as text documents (including memos, reports, and books), spreadsheets, charts, and presentations. Organizations and individuals that store their data in an open format such as OpenDocument avoid being locked into a single software vendor, leaving them free to switch software if their current vendor goes out of business, raises their prices, changes their software, or changes their licensing terms to something less favorable.

Open-source movie production is either an open call system in which a changing crew and cast collaborate in movie production, a system in which the end result is made available for re-use by others or in which exclusively open-source products are used in the production. The 2006 movie Elephants Dream is said to be the "world's first open movie",[74] created entirely using open-source technology.

An open-source documentary film has a production process allowing the open contributions of archival material footage, and other filmic elements, both in unedited and edited form, similar to crowdsourcing. By doing so, on-line contributors become part of the process of creating the film, helping to influence the editorial and visual material to be used in the documentary, as well as its thematic development. The first open-source documentary film is the non-profit "The American Revolution", which went into development in 2006, and will examine the role media played in the cultural, social and political changes from 1968 to 1974 through the story of radio station WBCN-FM in Boston.[75][76][77][78] The film is being produced by Lichtenstein Creative Media and the non-profit Filmmakers Collaborative. Open Source Cinema is a website to create Basement Tapes, a feature documentary about copyright in the digital age, co-produced by the National Film Board of Canada.[79] Open-source film-making refers to a form of film-making that takes a method of idea formation from open-source software, but in this case the 'source' for a filmmaker is raw unedited footage rather than programming code. It can also refer to a method of film-making where the process of creation is 'open' i.e. a disparate group of contributors, at different times contribute to the final piece.

Open-IPTV is IPTV that is not limited to one recording studio, production studio, or cast. Open-IPTV uses the Internet or other means to pool efforts and resources together to create an online community that all contributes to a show.

Education



Within the academic community, there is discussion about expanding what could be called the "intellectual commons" (analogous to the Creative Commons). Proponents of this view have hailed the Connexions Project at Rice University, OpenCourseWare project at MIT, Eugene Thacker's article on "open-source DNA", the "Open Source Cultural Database", Salman Khan's Khan Academy and Wikipedia as examples of applying open source outside the realm of computer software.

Open-source curricula are instructional resources whose digital source can be freely used, distributed and modified.

Another strand to the academic community is in the area of research. Many funded research projects produce software as part of their work. There is an increasing interest in making the outputs of such projects available under an open-source license. In the UK the Joint Information Systems Committee (JISC) has developed a policy on open-source software. JISC also funds a development service called OSS Watch which acts as an advisory service for higher and further education institutions wishing to use, contribute to and develop open-source software.

On 30 March 2010, President Barack Obama signed the Health Care and Education Reconciliation Act, which included $2 billion over four years to fund the TAACCCT program, which is described as "the largest OER (open education resources) initiative in the world and uniquely focused on creating curricula in partnership with industry for credentials in vocational industry sectors like manufacturing, health, energy, transportation, and IT".[80]

Innovation communities

The principle of sharing pre-dates the open-source movement; for example, the free sharing of information has been institutionalized in the scientific enterprise since at least the 19th century. Open-source principles have always been part of the scientific community. The sociologist Robert K. Merton described the four basic elements of the community—universal ism (an international perspective), communal ism (sharing information), disinterestedness (removing one's personal views from the scientific inquiry) and organized skepticism (requirements of proof and review) that accurately describe the scientific community today.

These principles are, in part, complemented by US law's focus on protecting expression and method but not the ideas themselves. There is also a tradition of publishing research results to the scientific community instead of keeping all such knowledge proprietary. One of the recent initiatives in scientific publishing has been open access—the idea that research should be published in such a way that it is free and available to the public. There are currently many open access journals where the information is available free online, however most journals do charge a fee (either to users or libraries for access). The Budapest Open Access Initiative is an international effort with the goal of making all research articles available free on the Internet.

The National Institutes of Health has recently proposed a policy on "Enhanced Public Access to NIH Research Information". This policy would provide a free, searchable resource of NIH-funded results to the public and with other international repositories six months after its initial publication. The NIH's move is an important one because there is significant amount of public funding in scientific research. Many of the questions have yet to be answered—the balancing of profit vs. public access, and ensuring that desirable standards and incentives do not diminish with a shift to open access.

Farmavita.Net is a community of pharmaceuticals executives that has recently proposed a new business model of open-source pharmaceuticals.[81] The project is targeted to development and sharing of know-how for manufacture of essential and life-saving medicines. It is mainly dedicated to the countries with less developed economies where local pharmaceutical research and development resources are insufficient for national needs. It will be limited to generic (off-patent) medicines with established use. By definition, a medicinal product has a "well-established use" if is used for at least 15 years, with recognized efficacy and an acceptable level of safety. In that event, the expensive clinical test and trial results could be replaced by appropriate scientific literature.

Benjamin Franklin was an early contributor eventually donating all his inventions including the Franklin stove, bifocals, and the lightning rod to the public domain.

New NGO communities are starting to use the open-source technology as a tool. One example is the Open Source Youth Network started in 2007 in Lisboa by ISCA members.[82]

Open innovation is also a new emerging concept which advocate putting R&D in a common pool. The Eclipse platform is openly presenting itself as an Open innovation network.[83]

Arts and recreation

Copyright protection is used in the performing arts and even in athletic activities. Some groups have attempted to remove copyright from such practices.[84]

In 2012, Russian music composer, scientist and Russian Pirate Party member Victor Argonov presented detailed raw files of his electronic opera "2032"[85] under free license CC-BY-NC 3.0. This opera was originally composed and published in 2007 by Russian label MC Entertainment as a commercial product, but then the author changed its status to free. In his blog [2] he said that he decided to open raw files (including wav, midi and other used formats) to the public in order to support worldwide pirate actions against SOPA and PIPA. Several Internet resources,[86][87][88] called "2032" the first open-source musical opera in history.

Other related movements

The following are events and applications that have been developed via the open source community, and echo the ideologies of the open source movement.[89]

Open Education Consortium — an organization composed of various colleges that support open source and share some of their material online. This organization, headed by Massachusetts Institute of Technology, was established to aid in the exchange of open source educational materials.

Wikipedia — user-generated online encyclopedia with sister projects in academic areas, such as Wikiversity — a community dedicated to the creation and exchange of learning materials[90][not in citation given]

Project Gutenberg — prior to the existence of Google Scholar Beta, this was the first supplier of electronic books and the very first free library project[90][not in citation given]

Synthetic Biology- This new technology is potentially important because it promises to enable cheap, lifesaving new drugs as well as helping to yield biofuels that may help to solve our energy problem. Although synthetic biology has not yet come out of its "lab" stage, it has potential to become industrialized in the near future. In order to industrialize open source science, there are some scientists who are trying to build their own brand of it.[91]

Ideologically-related movements

The open-access movement is a movement that is similar in ideology to the open source movement. Members of this movement maintain that academic material should be readily available to provide help with “future research, assist in teaching and aid in academic purposes.” The Open access movement aims to eliminate subscription fees and licensing restrictions of academic materials[92]

The free-culture movement is a movement that seeks to achieve a culture that engages in collective freedom via freedom of expression, free public access to knowledge and information, full demonstration of creativity and innovation in various arenas and promotion of citizen liberties.[93][citation needed]

Creative Commons is an organization that “develops, supports, and stewards legal and technical infrastructure that maximizes digital creativity, sharing, and innovation.” It encourages the use of protected properties online for research, education, and creative purposes in pursuit of a universal access. Creative Commons provides an infrastructure through a set of copyright licenses and tools that creates a better balance within the realm of “all rights reserved” properties.[94] The Creative Commons license offers a slightly more lenient alternative to “all rights reserved” copyrights for those who do not wish to exclude the use of their material.[95]

The Zeitgeist Movement is an international social movement that advocates a transition into a sustainable "resource-based economy" based on collaboration in which monetary incentives are replaced by commons-based ones with everyone having access to everything (from code to products) as in "open source everything".[96][97] While its activism and events are typically focused on media and education, TZM is a major supporter of open source projects worldwide since they allow for uninhibited advancement of science and technology, independent of constraints posed by institutions of patenting and capitalist investment.[98]

P2P Foundation is an “international organization focused on studying, researching, documenting and promoting peer to peer practices in a very broad sense”. Its objectives incorporate those of the open source movement, whose principles are integrated in a larger socio-economic model.[99]
