OurResearch , formerly known as ImpactStory , is a nonprofit organization that creates and distributes tools and services for libraries, institutions and researchers. The organization follows open practices with their data (to the extent allowed by providers' terms of service), code, and governance. OurResearch is funded by the Alfred P. Sloan Foundation , the National Science Foundation , and Arcadia Fund .
87-432: ImpactStory is the first open source , web-based tool released by OurResearch . It provides altmetrics to help researchers measure the impacts of their research outputs including journal articles, blog posts , datasets, and software. This aims to change the focus of the scholarly reward system to value and encourage web-native scholarship. It provides context to its metrics so that they are meaningful without knowledge of

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
261-720: 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
348-482: 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
435-412: A deadline. Software analysis begins with a requirements analysis to capture the business needs of the software. Challenges for the identification of needs are that current or potential users may have different and incompatible needs, may not understand their own needs, and change their needs during the process of software development. Ultimately, the result of analysis is a detailed specification for
522-996: A free API and data snapshot. The purpose of OpenAlex is to catalog publication sources, author information, and research topics. It also shows connections between these data points to provide a comprehensive, interlinked view of the global research system. It is considered an alternative to the Microsoft Academic Graph, which retired on December 31, 2021. OpenAlex contains extensive metadata across scientific works, authors, publication venues, institutions, and concepts. Specifically, it includes metadata for 209 million works such as journal articles and books; 13 million authors with disambiguated identities; metadata for 124,000 venues that host works, including journals and online repositories; metadata for 109,000 institutions; and 65,000 concepts from Wikidata , which are algorithmically linked to works using an automated hierarchical multi-tag classifier.

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
696-465: 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
783-452: 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
870-483: 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
957-462: 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

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
1131-420: 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
1218-411: 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
1305-524: 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
1392-484: 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
1479-472: 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
1566-671: 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
1653-416: 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
1740-405: 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
1827-413: 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

#17327879722011914-401: 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
2001-467: 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
2088-409: 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
2175-511: Is a framework that provides the viewpoints on the system and its environment , to be used in the software development process . It is a graphical representation of the underlying semantics of a view. The purpose of viewpoints and views is to enable human engineers to comprehend very complex systems and to organize the elements of the problem around domains of expertise . In the engineering of physically intensive systems, viewpoints often correspond to capabilities and responsibilities within
2262-408: Is a popular way of managing changes made to the software. Whenever a new version is checked in, the software saves a backup of all modified files. If multiple programmers are working on the software simultaneously, it manages the merging of their code changes. The software highlights cases where there is a conflict between two sets of changes and allows programmers to fix the conflict. A view model
2349-414: 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
2436-449: Is correctly incorporated with the newer software. Design involves choices about the implementation of the software, such as which programming languages and database software to use, or how the hardware and network communications will be organized. Design may be iterative with users consulted about their needs in a process of trial and error . Design often involves people expert in aspect such as database design , screen architecture, and
2523-833: Is essential to success. This is more easily achieved if the team is small, used to working together, and located near each other. Communications also help identify problems at an earlier state of development and avoid duplicated effort. Many development projects avoid the risk of losing essential knowledge held by only one employee by ensuring that multiple workers are familiar with each component. Software development involves professionals from various fields, not just software programmers but also individuals specialized in testing, documentation writing, graphic design , user support, marketing , and fundraising. Although workers for proprietary software are paid, most contributors to open-source software are volunteers. Alternately, they may be paid by companies whose business model does not involve selling
2610-404: 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
2697-399: Is helpful for new developers to understand the project when they begin working on it. In agile development, the documentation is often written at the same time as the code. User documentation is more frequently written by technical writers . Accurate estimation is crucial at the feasibility stage and in delivering the product on time and within budget. The process of generating estimations

As a result, testing, debugging, and revising the code becomes much more difficult. Code refactoring , for example adding more comments to the code, is a solution to improve the understandability of code. Testing is the process of ensuring that
2871-401: 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
2958-440: Is often delegated by the project manager . Because the effort estimation is directly related to the size of the complete application, it is strongly influenced by addition of features in the requirements—the more requirements, the higher the development cost. Aspects not related to functionality, such as the experience of the software developers and code reusability, are also essential to consider in estimation. As of 2019 , most of
3045-432: Is often used to break down the customer's requirements into pieces that can be implemented by software programmers. The underlying logic of the program may be represented in data-flow diagrams , data dictionaries , pseudocode , state transition diagrams , and/or entity relationship diagrams . If the project incorporates a piece of legacy software that has not been modeled, this software may be modeled to help ensure it
3132-443: 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

When tests are written before the code, this is called test-driven development . Production is the phase in which software is deployed to
3393-723: 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

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

Documentation comes in two forms that are usually kept separate—that intended for software developers, and that made available to the end user to help them use the software. Most developer documentation is in the form of code comments for each file, class , and method that cover the application programming interface (API)—how the piece of software can be accessed by another—and often implementation details. This documentation

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
3915-526: 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
4002-427: The actual cost and value of their subscriptions. The tool reduces information asymmetry in negotiations over subscriptions with publishers: in its paid tailored version, it allows to merge Unpaywall data about open access status and expected evolution in 5 years, article processing charges , usage statistics and the libraries' own parameters (such as the cost of ILL ) to calculate various indicators including
4089-489: The available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Another focus in many programming methodologies is the idea of trying to catch issues such as security vulnerabilities and bugs as early as possible ( shift-left testing ) to reduce the cost of tracking and fixing them. In 2009, it was estimated that 32 percent of software projects were delivered on time and budget, and with
4176-423: The code executes correctly and without errors. Debugging is performed by each software developer on their own code to confirm that the code does what it is intended to. In particular, it is crucial that the software executes on all inputs, even if the result is incorrect. Code reviews by other developers are often used to scrutinize new code added to the project, and according to some estimates dramatically reduce
4263-409: 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
4350-584: The cost effectiveness or net cost per use of a current or planned subscription (or lack thereof). Unpaywall Journals was used in 2020 by the SUNY Libraries Consortium to assist in the cancellation of their big deal with Elsevier , which was replaced by a subscription to 248 titles, allowing expected savings of 50–70% over the baseline, or 5 to 7 million dollars per year. OpenAlex is an open catalog of scholarly papers, authors, institutions, and more. OpenAlex launched in January 2022 with
4437-548: 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

There might also be a return to earlier development phases if user needs changed or were misunderstood. Software development is performed by software developers , usually working on a team. Efficient communications between team members
4611-430: The engineering organization. Fitness functions are automated and objective tests to ensure that the new developments don't deviate from the established constraints, checks and compliance controls. Intellectual property can be an issue when developers integrate open-source code or libraries into a proprietary product, because most open-source licenses used for software require that modifications be released under
4698-545: 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
4785-430: 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,
4872-477: The full functionality. An additional 44 percent were delivered, but missing at least one of these features. The remaining 24 percent were cancelled prior to release. Software development life cycle refers to the systematic process of developing applications . The sources of ideas for software products are plentiful. These ideas can come from market research including the demographics of potential new customers, existing customers, sales prospects who rejected
4959-446: 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
5046-443: 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
5133-561: The impact of research beyond only considering citations to journal articles. Unpaywall, begun as an interface for oaDOI.org , is a browser extension which finds legal free versions of (paywalled) scholarly articles. In July 2018, Unpaywall was reported to provide free access to 20 million articles, which accounts for about 47% of the articles that people search for with Unpaywall. As of 2024, Unpaywall claims to provide access to 49 million free articles. It further states that "Unpaywall users read 52% of research papers for free". In June 2017, it

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

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
5568-468: 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

Designers often attempt to find patterns in the software's functionality to spin off distinct modules that can be reused with object-oriented programming . An example of this is the model–view–controller , an interface between a graphical user interface and the backend . The central feature of software development is creating and understanding
5742-404: 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
5829-463: The process used for a development effort varies. The process may be confined to a formal, documented standard , or it can be customized and emergent for the development effort. The process may be sequential, in which each major phase (i.e. design, implement and test) is completed before the next begins, but an iterative approach – where small aspects are separately designed, implemented and tested – can reduce risk and cost and increase quality. Each of
5916-424: The product that developers can work from. Software analysts often decompose the project into smaller objects, components that can be reused for increased cost-effectiveness, efficiency, and reliability. Decomposing the project may enable a multi-threaded implementation that runs significantly faster on multiprocessor computers. During the analysis and design phases of software development, structured analysis
6003-723: 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
6090-466: The product, other internal software development staff, or a creative third party. Ideas for software products are usually first evaluated by marketing personnel for economic feasibility, fit with existing channels of distribution, possible effects on existing product lines, required features , and fit with the company's marketing objectives. In the marketing evaluation phase, the cost and time assumptions become evaluated. The feasibility analysis estimates

Software development Software development is the process of designing and implementing a software solution to satisfy a user . The process is more encompassing than programming , writing code , in that it includes conceiving the goal, evaluating feasibility, analyzing requirements , design , testing and release . The process
6264-503: The project's return on investment , its development cost and timeframe. Based on this analysis, the company can make a business decision to invest in further development. After deciding to develop the software, the company is focused on delivering the product at or below the estimated cost and time, and with a high standard of quality (i.e., lack of bugs) and the desired functionality. Nevertheless, most software projects run late and sometimes compromises are made in features or quality to meet
6351-465: 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
6438-482: 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
6525-510: 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
6612-409: 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
6699-427: The software that implements the desired functionality. There are various strategies for writing the code. Cohesive software has various components that are independent from each other. Coupling is the interrelation of different software components, which is viewed as undesirable because it increases the difficulty of maintenance . Often, software programmers do not follow industry best practices, resulting in code that
6786-403: The software, but something else—such as services and modifications to open source software. Computer-aided software engineering (CASE) is tools for the partial automation of software development. CASE enables designers to sketch out the logic of a program, whether one to be written, or an already existing one to help integrate it with new code or reverse engineer it (for example, to change
6873-426: The specific dataset: for example, instead of letting the reader guess whether having five forks on GitHub is common, ImpactStory would tell that the repository is in the 95th percentile of all GitHub repositories created that year. The metrics provided by ImpactStory can be used by researchers who want to know how many times their work has been downloaded and shared, and also research funders who are interested in
