Open source is defined as source code that is freely available to the public, allowing it to be modified and redistributed by individuals and companies under specific conditions. Products relying on open source can include permission to use the source code, design documentation, or the product content itself, enabling users to develop and reshape it to suit their needs. The open-source model relies on a decentralized development approach that fosters open collaboration between developers and users. Peer production is one of the core principles of the open-source model, where source codes, engineering blueprints, and documentation are made freely available to the public.
The open-source movement began as a reaction to the restrictions imposed by proprietary software, which prevents users from modifying codes or using them except with specific approval or licenses from the owning companies. Consequently, the open-source model emerged as an alternative that promotes transparency and freedom in software development and distribution. Among the projects relying on this model are appropriate open-source technology projects, open-collaboration drug discovery, and many other applications that benefit from the principle of public availability.
The principle of open access and redistribution
Open source provides comprehensive access to product design or blueprints through an open or free license, allowing the public to freely redistribute this design. Before the term “open source” became widely popularized, developers relied on a set of other terms expressing the same idea, but open source gained popularity with the rise of the internet and its rapid developments. The open-source software movement arose to clarify numerous issues related to copyright, licensing, the public domain, and consumer rights.
Generally, open source refers to computer software whose source code is publicly available, allowing anyone to use or modify it to fit their needs. The code is released according to software licensing terms, allowing other developers to download, modify, and republish their own versions (known as branching or forking) back to the tech community. As a result, large organizations have emerged to support the open-source movement, including the Apache Software Foundation, which supports numerous projects such as the Apache Hadoop framework and the well-known open-source HTTP server Apache HTTP.
Early history of the open-source movement
The history of technical information sharing dates back long before the advent of the internet and personal computers. For example, in the early days of the automotive industry, a number of capitalist monopolists held patent rights for the two-stroke gasoline engine filed by inventor George B. Selden. Thanks to their patent monopoly, they were able to control the industry, forcing car manufacturers to comply with their terms or face lawsuits.
In 1911, independent automaker Henry Ford won a legal challenge contesting the Selden patent. This victory largely invalidated the Selden patent and led to the formation of a new union later named the Automobile Board of Trade. This union implemented a cross-licensing agreement among all US automakers; under this agreement, companies shared technology and patents openly. By the time the United States entered World War II, 92 patents from Ford and 515 patents from other companies were being shared among manufacturers without financial exchange or litigation.
Beginnings of source code sharing
Early examples of source code sharing include IBM releasing operating system codes and other software in the 1950s and 1960s. A group known as SHARE was also formed to facilitate software sharing among users. In the 1960s, researchers on ARPANET, one of the earliest communication networks, used the Request for Comments (RFC) open process, which encouraged feedback in developing network protocols, leading to the birth of the early internet in 1969.
Source code sharing began across the internet when it was in its infancy, with software distributed via simple networks like UUCP, Usenet, IRC, and Gopher. A prominent example is the BSD system, which was widely distributed via the comp.os.linux newsgroup on Usenet, which was also a venue for discussing its development. Later, Linux adopted this model of open collaboration.
The emergence of the term “open source”
The term “open source” emerged in the late 1990s by a group of people within the free software movement who criticized the political agenda and moral philosophy of the term “free software.” Their goal was to reframe the debate to reflect a purely commercial stance, believing that the ambiguity of the term “free software” (where “free” can refer to freedom of use or zero cost) might deter companies from adopting the idea.
This group included prominent figures such as Christine Peterson, Todd Anderson, Larry Augustin, John “maddog” Hall, Sam Ockman, Michael Tiemann, and Eric S. Raymond. Peterson proposed the term “open source” during a meeting held in Palo Alto, California, in response to Netscape‘s announcement in January 1998 to release the source code for the Navigator browser. Linux developer Linus Torvalds endorsed the term the following day, gaining support from Phil Hughes at Linux Journal. On the other hand, Richard Stallman, founder of the Free Software Foundation (FSF), decided not to support the term. The foundation aimed to promote the development and use of free software, 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 greater emphasis on the ethical and political aspects of software freedom.
Open collaboration
The open-source model is a decentralized model that encourages open collaboration among contributors from diverse backgrounds and fields. Open collaboration is defined as an innovation or production system relying on participants who are not bound by formal coordination, interacting to produce an economic product that is made available to both contributors and non-contributors alike. Peer production is one of the main principles in open-source software development, where code, diagrams, and documentation are shared freely with the public.
The open-source software movement emerged as a response to the limitations of proprietary code, leading to the adoption of the model in various projects such as appropriate open-source technology and open-collaboration drug discovery.
Definition and principles of open collaboration
Researchers have identified several principles for successful open collaboration, including egalitarianism, meritocracy, and self-organization. Open collaboration refers to an innovation or production system relying on informal participants with a shared goal. These participants interact to produce a joint economic product that is available to both contributors and non-contributors alike. This definition represents a variety of models, such as open-source software projects, Wikipedia, and online forums. All of these projects share elements such as economic products, open access to contribution and consumption, interaction and exchange, and purposeful work that is not strictly coordinated.
The open license and its applications
The open license promotes comprehensive access through an open license, allowing users to view, modify, and redistribute product designs and blueprints. Open licenses include clear conditions on how code or designs can be used and shared freely, but with certain restrictions such as the obligation to respect copyright and attribute authors, or the requirement to distribute licensed software under the same license.
Applications of the open-source model in various fields
The open-source concept has significantly impacted many social and political fields, changing the ways information is shared and developed. Increasing interest in the open-source idea has prompted advocates in various fields to call for its application beyond software to include other areas such as scientific research and biotechnology, leading some to propose using open principles in hardware design and scientific research, among others.
The open-source movement has inspired the concept of open-source hardware, which makes engineering blueprints, schematics, and electronic designs available to the public so that anyone can benefit from, develop, or modify them. A famous example of open-source hardware is the Arduino project, a platform for professionals and hobbyists in electronics, allowing users to design and develop their own projects using open-source hardware.
Open-source software
Software is one of the fields that has benefited most from the open-source concept, where source code can be freely shared, developed, and modified by anyone. Operating systems like Linux and software like MediaWiki, which powers Wikipedia, are famous examples of open-source software. There is also much open-source software used worldwide in major organizations and enterprises, including operating systems, development tools, and office suites.
These projects include well-known software such as LibreOffice and the image editor GIMP, both of which are available for free and considered alternatives to costly proprietary software. Open-source software allows users to develop their own code and redistribute it freely, enhancing collaboration among programmers, companies, and technical communities. This model has enabled many major projects, such as Google Summer of Code, which provides financial grants to young contributors who successfully complete open-source software projects during the summer, with hundreds of organizations participating in 2021.
Open-source electronic hardware applications
In the field of electronic hardware, open-source hardware provides preliminary designs and specifications for free so that anyone can use, develop, and redistribute them. Electronic hardware platforms such as Openmoko, OpenRISC, and OpenSPARC processors are prominent examples of open-source hardware. There are also many other projects such as Teensy-based or similar control boards, which offer open-source electronic control boards allowing the design of motor control systems and sensors using various programming languages like C and Python, providing greater flexibility and innovation in electronic hardware design.
Open-source food and beverage industry
The application of open source has expanded into the food and beverage sector, giving rise to products based on open-source recipes that grant people the freedom to reproduce and modify the recipe. An example is Free Beer, developed by students from the IT University of Copenhagen in collaboration with an art collective to demonstrate how open-source concepts can be applied in non-digital fields. There are also open-source soft drinks like OpenCola, which are based on soft drink recipes similar to famous commercial drinks like Coca-Cola, developed by volunteers with recipes available to everyone.
Open digital content
The open content movement has led to many initiatives based on the same open-source principle but applied to digital content. These initiatives include projects like Creative Commons, which aims to provide licenses allowing authors and creators to distribute their digital content freely and legally. These licenses help promote open collaboration and creativity in digital production, whether through art, music, books, or videos. These licenses are also a core component of many educational and community projects relying on open content, such as Wikipedia, which allows users to add and edit content freely.
Open licenses and their applications in software and hardware
Open-source licenses rely on a unique model granting users freedom of access to source code or engineering designs, allowing them to modify and redistribute them without needing approval from the patent holder or licensor. However, certain restrictions may be imposed to ensure the preservation of copyright and original author attribution, as well as the requirement to distribute modified versions under the same open license terms (as in “Copyleft” licenses).
The GNU General Public License (GPL) is one of the most famous open licenses allowing software modification on the condition that modified versions are distributed under the same original license, ensuring the code remains open source and preventing any monopolistic attempts. The Open Source Initiative (OSI) provides a wide list of open licenses varying according to user needs, with some relying on strict conditions to preserve intellectual property rights while others offer more flexibility.
Social and political impacts of the open-source movement
The open-source movement has contributed to noticeable changes in communication and collaboration methods, encouraging increased transparency and freedom in many areas that previously lacked broad information access. The open-source movement has shifted certain economic and social concepts, moving production and collaboration from traditional competitive models to open models based on equality and meritocracy, encouraging the emergence of new projects such as collaborative sourcing in mass innovation (crowdsourcing) and collaborative consumption.
Furthermore, the success of the open-source movement has driven the emergence of platforms and communities relying on open participation, such as internet forums, mailing lists, and online communities. A prominent example of projects relying on open content is Wikipedia, which represents a successful embodiment of open collaboration and knowledge sharing.
Future developments in open-source applications
With the growing spread of open concepts and rising demand for free access to information, the open-source movement is expected to continue expanding into more fields and technologies. Many look forward to applying the open-source model in areas such as artificial intelligence, machine learning, and biotechnology, where open collaboration can help develop new technologies and innovative solutions to complex problems. There are also growing trends toward opening databases and making them publicly available, allowing developers and researchers to access massive data to study and develop advanced solutions based upon it.
In conclusion, the open-source model is a unique framework combining collaboration and technology while promoting values of transparency and innovation in a society increasingly reliant on digital technology. Open source serves as the cornerstone for the rapid technological evolution we witness today and represents a model to emulate in promoting free access to information and collective development toward a more inclusive and innovative future.
