Open source promotes universal access via anopen-sourceorfree licenseto a product's design or blueprint, and universal redistribution of that design or blueprint.[8][9]Before the phraseopen sourcebecame widely adopted, developers and producers used a variety of other terms, such asfree software,shareware,andpublic domain software.Open sourcegained hold with the rise of theInternet.[10]Theopen-source software movementarose to clarifycopyright,licensing,domain,and consumer issues.
Generally, open source refers to a computer program in which thesource codeis available to the general public for use or modification from its original design. Code is released under the terms of asoftware 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 theApache Software Foundation,which supports community projects such as the open-source frameworkApache Hadoopand the open-sourceHTTPserverApache HTTP.
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 capitalmonopolistsowned the rights to a2-cyclegasoline-engine patent originally filed byGeorge B. Selden.[11]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 automakerHenry Fordwon a challenge tothe Selden patent.The result was that the Selden patent became virtually worthless and a new association (which would eventually become theMotor Vehicle Manufacturers Association) was formed.[11]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.[11]By the time the US enteredWorld War II,92 Ford patents and 515 patents from other companies were being shared among these manufacturers, without any exchange of money (or lawsuits).[11]
Early instances of the free sharing of source code includeIBM's source releases of itsoperating systemsand other programs in the 1950s and 1960s, and theSHAREuser group that formed to facilitate the exchange of software.[12][13]Beginning in the 1960s,ARPANETresearchers 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 viaUUCP,Usenet,IRC,andGopher.BSD,for example, was first widely distributed by posts to comp.os.linux on the Usenet, which is also where its development was discussed.Linuxfollowed in this model.
Open source as a term emerged in the late 1990s by a group of people in thefree software movementwho 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.[14]In addition, the ambiguity of the term "free software" was seen as discouraging business adoption.[15][16]However, the ambiguity of the word "free" exists primarily in English as it can refer to cost. The group includedChristine Peterson,Todd Anderson,Larry Augustin,Jon Hall,Sam Ockman,Michael TiemannandEric S. Raymond.Peterson suggested "open source" at a meeting[17]held atPalo Alto, California,in reaction toNetscape's announcement in January 1998 of a source code release forNavigator.Linus Torvaldsgave his support the following day, and Phil Hughes backed the term inLinux Journal.Richard Stallman,the founder of the free software foundation (FSF) in 1985, quickly decided against endorsing the term.[17][18]The FSF's goal was to promote the development and use of free software, which they defined as software that grants users the freedom to run, study, share, and modify the code. This concept is similar to open source but places a greater emphasis on the ethical and political aspects of software freedom. Netscape released its source code under theNetscape Public Licenseand later under theMozilla Public License.[19]
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.[20]Shortly after, he founded TheOpen Source Initiativein collaboration withBruce Perens.[17]
The term gained further visibility through an event organized in April 1998 by technology publisherTim O'Reilly.Originally titled the "Freeware Summit" and later known as the "Open Source Summit",[21]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.[21]

Some economists agree that open-source is aninformation good[23]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 themarginal costof a product.Copyrightcreates a monopoly so that 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 aderivative work—such as a copy of a software program modified to fix a bug or add a feature, or aremixof 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 asCreative Commonshost websites where individuals can file for alternative "licenses", or levels of restriction, for their works.[24]
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 thepharmaceutical 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.[25]
There is evidence that open-source development creates enormous value.[26]For example, in the context ofopen-source hardwaredesign, digital designs are shared for free and anyone with access to digital manufacturing technologies (e.g.RepRap3D printers) can replicate the product for the cost of materials.[27]The original sharer may receive feedback and potentially improvements on the original design from thepeer productioncommunity.
Many open-source projects have a high economic value. According to the Battery Open Source Software Index (BOSS), the ten economically most important open-source projects are:[28][29]
The rank given is based on the activity regarding projects in online discussions, on GitHub, on search activity in search engines and on the influence on the labour market.
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.
Patron – For example,open-accesspublishing 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 US government are automatically released into thepublic domain.[citation needed]
Freemium– Give away a limited version for free and charge for a premium version (potentially using adual license).
Give away the product and charge something related – charge for support of open-sourceenterprise software,give away music but charge for concert admission.[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 riderscan also benefit without undermining the creation process.
Blockchain based licensing. Developers register their contributions on a blockchain and when usage licenses are generated the revenue is shared through the blockchain.[30]
The open-source model is a decentralizedsoftware developmentmodel that encouragesopen collaboration,[3][31]meaning "any system of innovation or production that relies on goal-oriented yet loosely coordinated participants who interact to create a product (or service) of economic value, which they make available to contributors and noncontributors alike."[3]A main principle ofopen-source software developmentispeer 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 inopen-source appropriate technology,[5]and open-source drug discovery.[6][7]
The open-source model for software development inspired the use of the term to refer to other forms of open collaboration, such as inInternet forums,[8]mailing lists[32]andonline communities.[33]Open collaboration is also thought to be the operating principle underlining a gamut of diverse ventures, includingTEDxand Wikipedia.[34]
Riehle et al. define open collaboration as collaboration based on three principles ofegalitarianism,meritocracy,andself-organization.[35]Levine and Prietula define open collaboration as "any system of innovation or production that relies on goal-oriented yet loosely coordinated participants who interact to create a product (or service) of economic value, which they make available to contributors and noncontributors alike."[3]This definition captures multiple instances, all joined by similar principles. For example, all of the elements – goods of economic value, open access to contribute and consume, interaction and exchange, purposeful yet loosely coordinated work – are present in an open-source software project, in Wikipedia, or in a user forum or community. They can also be present in a commercial website that is based onuser-generated content.In all of these instances of open collaboration, anyone can contribute and anyone can freely partake in the fruits of sharing, which are produced by interacting participants who are loosely coordinated.
An annual conference dedicated to the research and practice of open collaboration is the International Symposium on Wikis and Open Collaboration (OpenSym, formerly WikiSym).[36]As per its website, the group defines open collaboration as "collaboration that is egalitarian (everyone can join, no principled or artificial barriers to participation exist), meritocratic (decisions and status are merit-based rather than imposed) and self-organizing (processes adapt to people rather than people adapt to pre-defined processes)."[37]
Open source promotes universal access via anopen-sourceorfree licenseto a product's design or blueprint, and universal redistribution of that design or blueprint.[8][9]Before the phraseopen sourcebecame widely adopted, developers and producers used a variety of other terms.Open sourcegained hold in part due to the rise of the Internet.[38]Theopen-source software movementarose to clarifycopyright,licensing,domain,and consumer issues.
An open-source license is a type oflicensefor computer software and other products that allows thesource code,blueprint or design to be used, modified or shared (with or without modification) under defined terms and conditions.[39][40]This allows end users and commercial companies to review and modify the source code, blueprint or design for their own customization, curiosity or troubleshooting needs. Open-source licensed software is mostly availablefreeof charge, though this does not necessarily have to be the case. Licenses which only permit non-commercial redistribution or modification of the source code for personal use only are generally not considered as open-source licenses. However, open-source licenses may have some restrictions, particularly regarding the expression of respect to the origin of software, such as a requirement to preserve the name of the authors and a copyright statement within the code, or a requirement to redistribute the licensed software only under the same license (as in acopyleftlicense). One popular set ofopen-source softwarelicenses are those approved by the Open Source Initiative (OSI) based on theirOpen Source Definition(OSD).
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. ButEric Raymondand other founders of theopen-source movementhave 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.
Open-source softwareis software which 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.[43]
LibreOfficeand theGNU Image Manipulation Programare examples of open source software. As they do with proprietary software, users must accept the terms of a license when they use open source software—but the legal terms of open source licenses differ dramatically from those of proprietary licenses.
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:[44]
Linux(that much of world's server parks are running)
TheGoogle Summer of Code,often abbreviated to GSoC, is an international annual program in which Google awards stipends to contributors who successfully complete a free and open-source software coding project during the summer. GSoC is a large scale project with 202 participating organizations in 2021.[45]There are similar smaller scale projects such as the Talawa Project[46]run by thePalisadoes Foundation(a non profit based in California, originally to promote the use of information technology in Jamaica, but now also supporting underprivileged communities in the US)[47]
Open-source hardwareis hardware which initial specification, usually in a software format, is 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 theoperating system.
Arduino,a microcontroller platform for hobbyists, artists and designers.[49]
Simputer,an open hardwarehandheld computer,designed in India for use in environments where computing devices such as personal computers are deemed inappropriate.[50]
LEON:A family of open-source microprocessors distributed in a library with peripheralIP cores,openSPARCV8 specification, implementation available underGNU 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 underCERN 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.[51]
Open-source colas– cola soft drinks, similar toCoca-ColaandPepsi,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 keep their formulas secret and unknown to the general public.[54]
Free Beer(originallyVores Øl) – is an open-source beer created by students at theIT-Universityin Copenhagen together withSuperflex,an artist collective, to illustrate how open-source concepts might be applied outside the digital world.[55][56][57]
Open-content projects organized by the Wikimedia Foundation – Sites such as Wikipedia and Wiktionary have embraced the open-contentCreative Commonscontent 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 areProject Gutenberg[58]andWikisource,both of which post many books on which the copyright has expired and are thus in thepublic domain,ensuring that anyone has free, unlimited access to that content.
Open ICEcatis an open catalog for the IT, CE and Lighting sectors with product data-sheets based onOpen Content Licenseagreement. The digital content are distributed in XML and URL formats.
SketchUp's3D Warehouseis an open-source design community centered around the use of proprietary software that's distributed free of charge.
Pharmaceuticals – There have been several proposals for open-source pharmaceutical development,[60][61]which led to the establishment of the Tropical Disease Initiative[62]and the Open Source Drug Discovery for Malaria Consortium.[7]
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 the2011 E. coli O104:H4 outbreak.[63]
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.
Research – TheScience Commonswas created as an alternative to the expensive legal costs of sharing and reusing scientific works in journals etc.[64]
Research –The Open Solar Outdoors Test Field(OSOTF)[65]is a grid-connectedphotovoltaictest 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.[65]
Engineering –Hyperloop,a form of high-speed transport proposed by entrepreneurElon 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".[66]
Construction –WikiHouseis an open-source project for designing and building houses.[67][68]
Energy research – TheOpen Energy Modelling Initiativepromotes open-source models and open data in energy research and policy advice.
VIA OpenBookis 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.[69]
Open-source appropriate technology(OSAT) refers to technologies that are designed in the same fashion asfree and open-source software.[70]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 theRepRapto manufacture appropriate technology.[71]
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).[72]Other examples includeKhan Academyandwikiversity.At the university level, the use ofopen-source-appropriate technologyclassroom projects has been shown to be successful in forging the connection between science/engineering and social benefit:[73]This approach has the potential to use university students' access to resources and testing equipment in furthering the development ofappropriate technology.Similarly OSAT has been used as a tool for improvingservice learning.[74][75]
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.ITILis close to open source. It uses theCathedral 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 a3D Printer.[76]Calling itselfDefense Distributed,the group wants to facilitate "a working plastic gun that could be downloaded and reproduced by anybody with a 3D printer".[77]
Agrecol, a German NGO has developed an open-source licence for seeds operating withcopyleftand 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.[78]
Free and open-source software(FOSS) orfree/libre and open-source software(FLOSS) is openly shared source code that is licensed without any restrictions on usage, modification, or distribution.[citation needed]Confusion persists about this definition because the "free", also known as "libre", refers to the freedom of the product, not the price, expense, cost, or charge. For example, "being free to speak" is not the same as "free beer".[18]
Conversely, Richard Stallman argues the "obvious meaning" of term "open source" is that the source code is public/accessible for inspection, without necessarily any other rights granted, although the proponents of the term say the conditions in theOpen Source Definitionmust be fulfilled.[79]
Generally, open source refers to a computer program in which thesource codeis available to the general public for use for any (including commercial) purpose, 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 asoftware license.Depending on the license terms, others may then download, modify, and publish their version (fork) back to the community.

Open-source intelligence,an intelligence gathering discipline based on information collected from open sources (not to be confused with open-source artificial intelligence such asMycroft (software)).
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 oftencopyrighted,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 theDigital Millennium Copyright Act(DMCA), placed on attempts to circumvent anti-piracy technologies.[80]
Although artistic appropriation is often permitted underfair-usedoctrines, 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.[81]
The idea of an "open-source" culture runs parallel to "Free Culture",but is substantively different.Free cultureis a term derived from thefree 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"[clarification needed]) and ends.
Sites such asccMixteroffer up free web space for anyone willing to license their work under aCreative Commonslicense. The resulting cultural product is then available to download free (generally accessible) to anyone with an Internet connection.[82]Older, analog technologies such as the telephone or television have limitations on the kind of interaction users can have.
Through various technologies such aspeer-to-peernetworks andblogs,cultural producers can take advantage of vastsocial networksto distribute their products. As opposed to traditional media distribution, redistributing digital media on the Internet can be virtually costless. Technologies such asBitTorrentandGnutellatake advantage of various characteristics of the Internet protocol (TCP/IP) in an attempt to totally decentralize file distribution.
Open politics(sometimes known asOpen-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 termOpen-source politicswhich relates to the development of public policy under a set of rules and processes similar to the open-source software movement.
Open-source governanceis similar to open-source politics, but it applies more to the democratic process and promotes the freedom of information.
TheSouth Korean governmentwants to increase its use of free and open-source software, 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.[83]
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 theAoIRResearch Guidelines as an example of open-source ethics.[84]
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.[85]
Open-source journalismformerly referred to the standard journalistic techniques of news gathering and fact checking, reflectingopen-source intelligence,a similar term used in military intelligence circles. Now,open-source journalismcommonly refers to forms of innovative publishing ofonline 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 asuser created contentand listed alongside more traditional open-source projects such asOpenSolarisandLinux.
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, orfile transferrequired. 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 asLiveJournalorWordPress,use 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.
Messageboardsare 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 banningspammers.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 usephpBB,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.
OpenDocumentis anopendocument file formatfor 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 beinglocked intoa 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 theirlicensingterms to something less favorable.
Open-source movie productionis either an open call system in which a changing crew and cast collaborate in movie production, a system in which the result is made available for re-use by others or in which exclusively open-source products are used in the production. The 2006 movieElephants Dreamis said to be the "world's first open movie",[87]created entirely using open-source technology.
An open-source documentary film has a production process allowing the open contributions of archival materialfootage,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-profitWBCN and 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.[88][89][90][91]The film is being produced by Lichtenstein Creative Media and the non-profit Center for Independent Documentary. 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.[92]Open-source film-makingrefers 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-IPTVisIPTVthat 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.
Within the academic community, there is discussion about expanding what could be called the "intellectual commons" (analogous to theCreative Commons). Proponents of this view have hailed theConnexionsProject atRice University,OpenCourseWareproject atMIT,Eugene Thacker's article on "open-source DNA", the "Open Source Cultural Database",Salman Khan'sKhan Academyand Wikipedia as examples of applying open source outside the realm of computer software.
Open-source curriculaare 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. Due to the benefits of sharing software openly in scientific endeavours,[93]there is an increasing interest in making the outputs of research projects available under an open-source license. In the UK theJoint Information Systems Committee (JISC)has developed a policy on open-source software. JISC also funds a development service calledOSS Watchwhich 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 theTAACCCT 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".[94]
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 sociologistRobert K. Mertondescribed the four basic elements of the community—universalism (an international perspective), communalism (sharing information), objectivity (removing one's personal views from the scientific inquiry) and organized skepticism (requirements of proof and review) that describe the (idealised) scientific community.
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 beenopen 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). TheBudapest Open Access Initiativeis an international effort with the goal of making all research articles available free on the Internet.
TheNational Institutes of Healthhas 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.
Benjamin Franklinwas an early contributor eventually donating all his inventions including theFranklin stove,bifocals,and thelightning rodto 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.[95]Open innovationis also a new emerging concept which advocate putting R&D in a common pool. TheEclipseplatform is openly presenting itself as an Open innovation network.[96]
Copyright protection is used in the performing arts and even in athletic activities. Some groups have attempted to remove copyright from such practices.[97]
In 2012, Russian music composer, scientist andRussian Pirate PartymemberVictor Argonovpresented detailed raw files of his electronic opera "2032"[98]under free licenseCC BY-NC 3.0(later relicensed underCC BY-SA 4.0[99]). This opera was originally composed and published in 2007 by Russian labelMC Entertainmentas a commercial product, but then the author changed its status to free. In his blog[100]he said that he decided to open raw files (including wav, midi and other used formats) to the public to support worldwide pirate actions againstSOPAandPIPA.Several Internet resources called "2032" the first open-source musical opera in history.[101][102][103][104]

Notable events and applications that have been developed via theopen source community,and echo the ideologies of the open source movement,[105]include theOpen Education Consortium,Project Gutenberg,Synthethic Biology, and Wikipedia. The Open Education Consortium is an organization composed of various colleges that support open source and share some of their material online. This organization, headed byMassachusetts Institute of Technology,was established to aid in the exchange of open source educational materials. Wikipedia is a user-generatedonline encyclopediawith sister projects in academic areas, such asWikiversity—a community dedicated to the creation and exchange of learning materials.[106][failed verification]
Prior to the existence ofGoogle ScholarBeta, Project Gutenberg was the first supplier ofelectronic booksand the first free library project.[106][failed verification]Synthetic Biology is a new technology that 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. To industrialize open source science, there are some scientists who are trying to build their own brand of it.[107]
Theopen-access movementis 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.[108]Thefree-culture movementis 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.[109][citation needed]Creative Commonsis 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.[110]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.[111]
The Zeitgeist Movement(TZM) is an international social movement that advocates a transition into asustainable"resource-based economy" based oncollaborationin which monetary incentives are replaced by commons-based ones with everyonehaving accessto everything (from code to products) as in "open source everything".[112][113]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.[114]P2P Foundation is an "international organization focused on studying, researching, documenting and promotingpeer to peer practicesin a very broad sense. "Its objectives incorporate those of the open source movement, whose principles are integrated in a larger socio-economic model.[115]
