Open source
Open source describes practices in production and development that promote access to the end product's sources. Some consider it as a
philosophy, and others consider it as a
pragmatic methodology. Before
open source became widely adopted, developers and producers used a variety of phrases to describe the concept; the term
open source gained popularity with the rise of the
Internet and its enabling of diverse production models, communication paths, and interactive communities.
[The complexity of such communication relates to Brooks' law, and it is also described by Eric S. Raymond, "Brooks predicts that as your number of programmers N rises, work performed scales as N but complexity and vulnerability to bugs rises as N-squared. N-squared tracks the number of communications paths (and potential code interfaces) between developers' code bases." -- "The Revenge of the Hackers". 2000.] Subsequently,
open source software became the most prominent face of open source.
The open source model can allow for the concurrent use of different agendas and approaches in production, in contrast with more centralized models of development such as those typically used in commercial software companies.
[Raymond, Eric S. The Cathedral and the Bazaar. ed 3.0. 2000.]Those involved with
journalism and
open source intelligence used the earliest known practices of open source that focused on accessibility rather than modification of sources. Software developers used to commonly release their code under
public domain until they wanted to control how such freely accessible sources are modified and distributed. Developers, like the
Free Software Foundation, began to license their work, but they still kept it as
free software.
The "open source" label came out of a strategy session
[History of the OSI. Open Source Initiative. 2006.] held at
Palo Alto in reaction to
Netscape's January
1998 announcement of a source code release for
Navigator. The group of individuals at the session included
Christine Peterson who suggested "open source" and also included
Todd Anderson,
Larry Augustin,
Jon Hall,
Sam Ockman, and
Eric S. Raymond. They used the opportunity before the release of Navigator's source code to clarify a potential confusion caused by the
ambiguity of the word free in
English, so that the perception of
free software is not anti-commercial. Netscape listened and released their code as open source under the name of
Mozilla.
The term was given a big boost at 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"
[Open Source Summit Linux Gazette. 1998.], the event brought together 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 of
Netscape, and
Eric Raymond. At that meeting, the confusion caused by the name "free software" was brought up. 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 that evening.
This milestone may be commonly seen as the birth of the
open source movement. However, earlier researchers with access to the
Advanced Research Projects Agency Network (ARPANET) used a process called
Request for Comments, which is similar to
open standards, to develop telecommunication network protocols. Characterized by contemporary open source work, this collaborative process led to the birth of the
Internet in 1969.
The
Open Source Initiative formed in February 1998 by
Eric S. Raymond and
Bruce Perens. With at about 20 years of evidence from case histories of closed development versus open development already provided by the Internet, the OSI continued to present the 'open source' case to commercial businesses. They sought to bring a higher profile to the practical benefits of freely available source code, and they wanted to bring major software businesses and other high-tech industries into open source. Bruce Perens adapted
Debian's Free Software Guidelines to make the
Open Source Definition.
[Perens, Bruce. Open Sources: Voices from the Open Source Revolution. O'Reilly Media. 1999.]Critics have said that the term "open source" fosters an ambiguity of a different kind, in that it confuses the mere availability of the source with the freedom to use, modify, and redistribute it. Developers have used the term Free/Open-Source Software (
FOSS), or Free/Libre/Open-Source Software (
FLOSS), consequently, to describe open-source software that is freely available and free of charge.
Software is not the only field affected by open source; many fields of study and social and political views have been affected by the growth of the concept of open source. Advocates in one field will often support the expansion of open source in other fields, including
Linus Torvalds who is quoted as saying, "the future is open source everything."
The open source movement has been the inspiration for increased
transparency and liberty in other fields, including the release of
biotechnology research by
CAMBIA,
Wikipedia, and other projects. The open-source concept has also been applied to media other than computer programs, e.g., by
Creative Commons. It also constitutes an example of user innovation (see for example the book
Democratizing Innovation). Often, open source is an expression where it simply means that a system is available to all who wish to work on it.
Agriculture

Beverages**
OpenCola â€" An idea inspired by the
open source movement. Soft drink giants like Coke and Pepsi hold their formulas as closely guarded secrets. Now volunteers have posted
the recipe for a similar
cola drink on the
Internet. The taste is said to be comparable to that of the standard beverages.
**
Beer â€" A beer recipe called
Vores Øl. Following its release, an article in
Wired magazine commented that "as open source spreads beyond software to online encyclopedias like
Wikipedia and biological research, it was only a matter of time before somebody created an open-source beer".
[Cohn, David. "Free Beer for Geeks". Wired News. 18 July 2005.] The beer was created by students at the IT-University in
Copenhagen together with
Superflex, a Copenhagen-based artist collective, to illustrate how open source concepts might be applied outside the digital world. The concept expands upon a statement found in the Free Software Definition: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech' not as in 'free beer.'"
[Stallman, Richard M. The Free Software Definition. Free Software Foundation. 2005.]** But before that In 2002 a beer company in
Australia,
Brewtopia, started an open source brewery which invited the general population to be involved in the development and ownership of the brewery, but asking them to vote on the development of every aspect of their beer, Blowfly, and its road to market. In return for their feedback and input, they received shares in the company, which is not publicly traded on one of the
Stock Exchanges 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 their own beers online.
Content
*
Open-content projects organized by the Wikimedia Foundation â€" Sites such as
Wikipedia and
Wiktionary have embraced the open-content
GFDL and
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. Some have noted that the Wikipedia editorial process is similar to the
bazaar-style development process described in
Eric Raymond's essay,
The Cathedral and the Bazaar. Another site embracing open source-like ideals is
Project Gutenberg: it posts many books on which the copyright has expired and are thus in the
Public Domain which ensures that anyone can use that content for any purpose whatsoever.
* 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. Possibly the only example of free, bazaar-model open source business information is
Core Practice.
*
Yellowikis is a very successful example company listings. Anyone can access or add to it for free. Unfortunately it is so successful that it has attracted a legal challenge.
Health
*
Medicine Pharmaceuticals â€" There have been several proposals for open-source
pharmaceutical development, such as the article
Finding Cures for Tropical Diseases: Is Open Source an Answer?, which led to the establishment of the
Tropical Disease Initiative. There are also a number of not-for-profit "virtual pharmas" such as the
Institute for One World Health and the
Drugs for Neglected Diseases Initiative.
Technology
*
Computer software**
Open source software â€" 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. Open source code evolves through community cooperation. These communities are composed of individual programmers as well as very large companies. Some examples of open source initiatives are
Linux,
Eclipse,
Apache,
Tomcat web server,
Moodle,
Mozilla,
Mediawiki (the software that runs Wikipedia), and various other projects hosted on
SourceForge and elsewhere.
*
Computer hardware**
Open source hardware â€" 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. An example of Open Source Hardware initiatives are:
Sun Microsystem's
OpenSPARC T1 Multicore processor. Sun states in their Press release: "The source code will be released under an Open Source Initiative (OSI)-approved open source license."
*
Open design â€" which involves applying open source methodologies to the design of artifacts and systems in the physical world. Very nascent but has huge potential.
*
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).
Open source as applied to culture defines a culture in which
fixations are made generally available. Participants in such an
open source culture are able to modify those products, if needed, and redistribute them back into the community or other organizations.
Government
*
Open source government â€"
primarily refers to use of open source software and technologies in traditional government organizations and government operations such as voting.
*
Open source politics â€" is a term used to describe a political process that uses Internet technologies such as blogs and email to provide for a rapid feedback mechanism between political organizations and their supporters. There is also an alternative conception of the term 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 â€" is similar to open source politics, but it applies more to the democratic process and promotes the freedom of information.
Media
*
Open source journalism â€" referred to the standard journalistic techniques of news gathering and fact checking, and reflected a similar term that was in use from 1992 in military intelligence circles,
open source intelligence. It is now commonly used to describe forms of innovative publishing of
online journalism, rather than the sourcing of news stories by a professional journalist.
*
OpenDocument â€" 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 in to 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.
*
Creative Commons â€" A
non-profit organization devoted to expand the range of
creative work available for others legally to build upon and share.
*
Open source movie production - 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"
[http://www.elephantsdream.org/], created entirely using open source technology.
*
Open source documentary - A documentary film whose production process involves the open contributions of archival material, footage, and other filmic elements, both in unedited and edited form. 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, "The American Revolution" is currently in production.
*
Open Source Filmmaking - Open Source Filmmaking refers to a form of filmmaking that takes a method of idea formation from open source software, but in this case the 'source' for a film maker is raw unedited footage rather than programming code. It can also refer to a method of filmmaking where the process of creation is 'open' i.e. a disparate group of contributors, at different times contribute to the final piece.
*
Open-IPTV -
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
*
Open Source Curriculum - Open Source Curriculum refers to instructional resources whose digital source can be freely used, distributed and modified, typically by classroom educators. The open source curriculum development process invites the feedback and participation in a community of educational practitioners working to create a course or unit of study. Such development communities can form ad-hoc, within the same subject area or around a common student need, and allow for a variety of editing and workflow structures.
OpenEducator, a non-profit organization launched in 2006 using the open source
Drupal CMS, aims to support an open source curriculum development community for K-12 educators.
Innovation communities
* Open Source concepts and structures can be used to organize communities. At
Bootstrap Austin, an open source community, entrepreneurs provide negotiated products/services at no cost to the group. The entrepreneur benefits by gaining reputation in the community, experience and an improved product. The community is at once a customer and Evangelist for the product/service. The entrepreneur monetizes their product or service outside the Bootstrap community.
Arts and recreation
