72-531: Scran works in partnership with over 300 cultural institutions in Scotland and the rest of the UK who contribute material to the online service. The online learning resource service hosts nearly 490,000 images, movies and sounds from museums, galleries, archives and the media. Subscribers can download and reuse these for personal and educational use in accordance with the subscriber licence. The online service also provides

144-529: A Creative Commons license. The resulting cultural product is then available to download free (generally accessible) to anyone with an Internet connection. 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

216-720: 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. These self-made protections free

288-482: A computer program in which the source code is 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 a software license . Depending on the license terms, others may then download, modify, and publish their version (fork) back to

360-520: A meeting 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 foundation (FSF) in 1985, quickly decided against endorsing the term. The FSF's goal was to promote

432-465: A more commercially minded position. In addition, the ambiguity of the term "free software" was seen as discouraging business adoption. However, the ambiguity of the word "free" exists primarily in English as it can refer to cost. The group included Christine Peterson , Todd Anderson, Larry Augustin , Jon Hall , Sam Ockman , Michael Tiemann and Eric S. Raymond . Peterson suggested "open source" at

504-452: 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

576-632: A new body, Historic Environment Scotland , and Scran likewise followed and merged into Historic Environment Scotland. Scran was formed in 1996, and its founding partners were The National Museums of Scotland , The Royal Commission on the Ancient and Historical Monuments of Scotland , Museums Galleries Scotland and, by invitation, the Scottish Consultative Council on the Curriculum . In its first five years, it engaged in

648-408: A peak of 1.1 million hits per day. Scran utilises open source software and runs on a cluster server configuration with MySQL and PHP under Linux . The searchable database is over 7 GB and total storage including all assets is over 5 TB . A number of additional websites are hosted as linked services. The whole system developed by Scran including ScranBase and all the tools like Create and Stuff

720-483: A product (or service) of economic value, which they make available to contributors and noncontributors alike." 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 Misplaced Pages, or in

792-462: A product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase open source became widely adopted, developers and producers used a variety of other terms. Open source gained hold in part due to the rise of the Internet. The open-source software movement arose to clarify copyright , licensing , domain , and consumer issues. An open-source license

864-457: 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

936-420: A product. Copyright creates 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

1008-411: 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. There

1080-559: A range of tools for users "to do stuff with things they find". A number of institutions use Scran's open source online tool - Scran-in-a-Box - to provide access to their own data. Until 2008, Scran was a stand-alone charity. From 2008 to 2015 it was managed by The Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS), and had two arms: The Scran Trust, a charitable arm that provided educational access to its records, and Scran Ltd., its wholly owned trading arm. In October 2015, RCAHMS merged with Historic Scotland to form

1152-524: 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

1224-484: 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 a copyleft license). One popular set of open-source software licenses are those approved by the Open Source Initiative (OSI) based on their Open Source Definition (OSD). Social and political views have been affected by

1296-472: 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 result is made available for re-use by others or in which exclusively open-source products are used in

1368-671: 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: Some publishers of open-access journals have argued that data from food science and gastronomy studies should be freely available to aid reproducibility . A number of people have published creative commons licensed recipe books. An open-source robot

1440-454: A stable blue or black dye. Where the India ink blocks the ultra-violet light the coating does not convert and remains soluble. The image can be seen forming. When a strong image is seen the frame is brought indoors to stop the process. The unconverted coating is washed away, and the paper is then dried. The result is a copy of the original image with the clear background area rendered dark blue and

1512-416: 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 , use open-source software that

1584-405: A user forum or community. They can also be present in a commercial website that is based on user-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

1656-413: A vote, and the winner was announced at a press conference the same evening. Some economists agree that open-source is an information good 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

1728-467: A white background. The drawings are also called blue-lines or bluelines. Other comparable dye-based prints were known as blacklines. Diazo prints remained in use until they were replaced by xerographic print processes. Xerography is standard copy machine technology using toner on copy paper . When large size xerography machines became available, c. 1975, they replaced the older printing methods. As computer-aided design techniques came into use,

1800-553: A wide-ranging scheme of grant awards which allowed cultural organisations to digitise parts of their collections to be made available for educational purposes. This was Millennium Commission funded through the UK Lottery. It developed an advanced licensing system, commended by many, in which the institution retained ownership of the digitised assets, but made these available under licence to Scran. There followed further large grant aid partner projects with NOF Digitise funding through

1872-401: 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 , and open-source drug discovery. The open-source model for software development inspired the use of

1944-467: Is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open source model is a decentralized software development model that encourages open collaboration . A main principle of open source software development is peer production , with products such as source code, blueprints , and documentation freely available to

2016-409: Is a robot whose blueprints, schematics, or source code are released under an open-source model Free and open-source software (FOSS) or free/libre and open-source software (FLOSS) is openly shared source code that is licensed without any restrictions on usage, modification, or distribution. Confusion persists about this definition because the "free", also known as "libre", refers to the freedom of

2088-414: Is a type of license for computer software and other products that allows the source code , blueprint or design to be used, modified or shared (with or without modification) under defined terms and conditions. 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

2160-582: Is available for others to use as Scran-in-a Box. The National Museums Scotland Collections Database, the Scottish Stained Glass Trust, the William Wallace Website, The Virtual Hamilton Palace Trust and Robert Gordon University use "Scran-in-a-Box" tool. 55°56′27.37″N 3°10′47.08″W  /  55.9409361°N 3.1797444°W  / 55.9409361; -3.1797444 Open source Open source

2232-474: Is based on a photosensitive ferric compound. The best known is a process using ammonium ferric citrate and potassium ferricyanide . The paper is impregnated with a solution of ammonium ferric citrate and dried. When the paper is illuminated, a photoreaction turns the trivalent ferric iron into divalent ferrous iron. The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide ( Prussian blue or Turnbull's blue ) with

2304-404: Is evidence that open-source development creates enormous value. 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. The original sharer may receive feedback and potentially improvements on the original design from

2376-401: Is mostly available free of 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

2448-443: 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

2520-402: Is placed on top of the sensitized paper, and both are clamped under glass, in a daylight exposure frame, which is similar to a picture frame. The frame is put out into daylight, requiring a minute or two under a bright sun, or about ten minutes under an overcast sky to complete the exposure. Where ultra-violet light is transmitted through the tracing paper, the light-sensitive coating converts to

2592-723: Is 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. LibreOffice and the GNU Image Manipulation Program are 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

2664-600: Is the International Symposium on Wikis and Open Collaboration (OpenSym, formerly WikiSym). 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)." Open source promotes universal access via an open-source or free license to

2736-579: The National Library of Scotland . Scran continues to add records to its database from institutions and individuals. Technical innovations include "Create" functions that allow user creation of instant documents, the ability for users to save their favourite records to a password-protected "Stuff" account and share these with other Scran users, mapping functions and enhanced cross searching such as SRU / SRW . The service hosts nearly 490,000 resources with additional educational materials and delivers

2808-413: The machine tools used to make the part. In the case of construction plans, such as road work or erecting a building, the supervising workers may view the "blueprints" directly on displays, rather than using printed paper sheets. These displays include mobile devices, such as smartphones or tablets . Software allows users to view and annotate electronic drawing files. Construction crews use software in

2880-564: The peer production community. 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: 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

2952-549: The source code is available to the general public for use or modification from its original design. 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

3024-480: The "Open Source Summit", 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

3096-526: 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. Open-source ethics is split into two strands: 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. Open-source journalism formerly referred to

3168-409: The community. 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

3240-399: The designs were printed directly using a computer printer or plotter . In most computer-aided design of parts to be machined, paper is avoided altogether, and the finished design is an image on the computer display. The computer-aided design program generates a computer numerical control sequence from the approved design. The sequence is a computer file which will control the operation of

3312-548: 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 the Netscape Public License and later under the Mozilla Public License . Raymond

3384-418: The divalent iron. Excess ammonium ferric citrate and potassium ferricyanide are then washed away. The process is also known as cyanotype . This is a simple process for the reproduction of any light transmitting document. Engineers and architects drew their designs on cartridge paper ; these were then traced on to tracing paper using India ink for reproduction whenever needed. The tracing paper drawing

3456-545: The exchange of money among all the manufacturers. 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). 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

3528-430: The exchange of software. 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,

3600-543: The field to edit, share, and view blueprint documents in real-time. Many of the original paper blueprints are archived since they are still in use. In many situations their conversion to digital form is prohibitively expensive. Most buildings and roads constructed before c. 1990 will only have paper blueprints, not digital. These originals have significant importance to the repair and alteration of constructions still in use, e.g. bridges, buildings, sewer systems, roads, railroads, etc., and sometimes in legal matters concerning

3672-446: 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

3744-443: 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

3816-560: The image reproduced as a white line. This process has several features: Introduction of the blueprint process eliminated the expense of photolithographic reproduction or of hand-tracing of original drawings. By the later 1890s in American architectural offices, a blueprint was one-tenth the cost of a hand-traced reproduction. The blueprint process is still used for special artistic and photographic effects, on paper and fabrics. Various base materials have been used for blueprints. Paper

3888-429: The individual programmers who start an open-source project may end up establishing companies offering products or services incorporating open-source programs. Examples of open-source software products are: The Google 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

3960-708: 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. 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

4032-436: The open-source framework Apache Hadoop and the open-source HTTP server Apache 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 capital monopolists owned the rights to a 2-cycle gasoline-engine patent originally filed by George B. Selden . By controlling this patent, they were able to monopolize

4104-468: 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 CAMBIA Even the research methodologies themselves can benefit from the application of open-source principles. It has also given rise to the rapidly-expanding open-source hardware movement. Open-source software

4176-404: The phrase open source became widely adopted, developers and producers used a variety of other terms, such as free software , shareware , and public domain software . Open source gained hold with the rise of the Internet. The open-source software movement arose to clarify copyright , licensing , domain , and consumer issues. Generally, open source refers to a computer program in which

4248-723: The product, not the price, expense, cost, or charge. For example, "being free to speak" is not the same as "free beer". 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 the Open Source Definition must be fulfilled. "Free and open" should not be confused with public ownership ( state ownership ), deprivatization ( nationalization ), anti-privatization ( anti-corporate activism ), or transparent behavior . Generally, open source refers to

4320-434: The production. The 2006 movie Elephants Dream is said to be the "world's first open movie", created entirely using open-source technology. Blueprint A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets introduced by Sir John Herschel in 1842. The process allowed rapid and accurate production of an unlimited number of copies. It

4392-465: The proprietary license model. Examples include: The open-source model is a decentralized software development model that encourages open collaboration , 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." A main principle of open-source software development

4464-482: The protective actions of copyright owners create what some call a " chilling effect " among cultural practitioners. 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

4536-510: 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 spammers . Other common board features are private messages (where users can send messages to one another) as well as chat (a way to have

4608-409: 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 , and open source drug discovery. 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. Before

4680-683: 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

4752-754: The summer. GSoC is a large scale project with 202 participating organizations in 2021. There are similar smaller scale projects such as the Talawa Project run by the Palisadoes 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) Open-source hardware is hardware which initial specification, usually in

4824-560: 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. 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,

4896-1099: The term to refer to other forms of open collaboration, such as in Internet forums , mailing lists and online communities . Open collaboration is also thought to be the operating principle underlining a gamut of diverse ventures, including TEDx and Misplaced Pages. Open collaboration is the principle underlying peer production , mass collaboration , and wikinomics . It was observed initially in open-source software, but can also be found in many other instances, such as in Internet forums , mailing lists , Internet communities, and many instances of open content , such as Creative Commons . It also explains some instances of crowdsourcing , collaborative consumption , and open innovation . Riehle et al. define open collaboration as collaboration based on three principles of egalitarianism , meritocracy , and self-organization . 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

4968-505: Was a common choice; for more durable prints linen was sometimes used, but with time, the linen prints would shrink slightly. To combat this problem, printing on imitation vellum and, later, polyester film ( Mylar ) was implemented. Traditional blueprints became obsolete when less expensive printing methods and digital displays became available. In the early 1940s, cyanotype blueprint began to be supplanted by diazo prints , also known as whiteprints . This technique produces blue lines on

5040-534: 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. Shortly after, he founded The Open Source Initiative in collaboration with Bruce Perens . 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

5112-454: 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 emerged in the late 1990s 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

5184-743: Was widely used for over a century for the reproduction of specification drawings used in construction and industry. Blueprints were characterized by white lines on a blue background, a negative of the original. Color or shades of grey could not be reproduced. The process is obsolete, largely displaced by the diazo-based whiteprint process, and later by large-format xerographic photocopiers. It has almost entirely been superseded by digital computer-aided construction drawings. The term blueprint continues to be used informally to refer to any floor plan (and by analogy, any type of plan ). Practising engineers, architects, and drafters often call them "drawings", "prints", or "plans". The blueprint process
