Open data is the idea that some data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control.The goals of the open-source data movement are similar to those of other "open(-source)" movements such as open-source software, hardware, open content, open education, open educational resources, open government, open knowledge, open access, open science, and the open web. Paradoxically, the growth of the open data movement is paralleled by a rise in intellectual property rights. The philosophy behind open data has been long established (for example in the Mertonian tradition of science), but the term "open data" itself is recent, gaining popularity with the rise of the Internet and World Wide Web and, especially, with the launch of open-data government initiatives such as Data.gov, Data.gov.uk and Data.gov.in.
Open data can also be linked data; when it is, it is linked open data. One of the most important forms of open data is open government data (OGD), which is a form of open data created by ruling government institutions. Open government data's importance is borne from it being a part of citizens' everyday lives, down to the most routine/mundane tasks that are seemingly far removed from government.
The concept of open data is not new, but a formalized definition is relatively new. Conceptually, open data as a phenomenon denotes that governmental data should be available to anyone with a possibility of redistribution in any form without any copyright restriction.One more definition is the Open Definition which can be summarized in the statement that "A piece of data is open if anyone is free to use, reuse, and redistribute it – subject only, at most, to the requirement to attribute and/or share-alike." Other definitions, including the Open Data Institute's "Open data is data that anyone can access, use or share", have an accessible short version of the definition but refer to the formal definition.
Open data may include non-textual material such as maps, genomes, connectomes, chemical compounds, mathematical and scientific formulae, medical data, and practice, bioscience and biodiversity. Problems often arise because these are commercially valuable or can be aggregated into works of value. Access to, or re-use of, the data is controlled by organisations, both public and private. Control may be through access restrictions, licenses, copyright, patents and charges for access or re-use. Advocates of open data argue that these restrictions are against the common good and that these data should be made available without restriction or fee. In addition, it is important that the data are re-usable without requiring further permission, though the types of re-use (such as the creation of derivative works) may be controlled by a license.
A typical depiction of the need for open data:
Numerous scientists have pointed out the irony that right at the historical moment when we have the technologies to permit worldwide availability and distributed process of scientific data, broadening collaboration and accelerating the pace and depth of discovery ... we are busy locking up that data and preventing the use of correspondingly advanced technologies on knowledge.
Creators of data often do not consider the need to state the conditions of ownership, licensing and re-use; instead presuming that not asserting copyright puts the data into the public domain. For example, many scientists do not regard the published data arising from their work to be theirs to control and consider the act of publication in a journal to be an implicit release of data into the commons. However, the lack of a license makes it difficult to determine the status of a data set and may restrict the use of data offered in an "Open" spirit. Because of this uncertainty it is also possible for public or private organizations to aggregate said data, protect it with copyright and then resell it.
The issue of indigenous knowledge (IK) poses a great challenge in terms of capturing, storage and distribution. Many societies in third-world countries lack the technicality processes of managing the IK.
At his presentation at the XML 2005 conference, Connollydisplayed these two quotations regarding open data:
Open data can come from any source. This section lists some of the fields that publish (or at least discuss publishing) a large amount of open data.
The concept of open access to scientific data was institutionally established with the formation of the World Data Center system, in preparation for the International Geophysical Year of 1957–1958.The International Council of Scientific Unions (now the International Council for Science) oversees several World Data Centres with the mandate to minimize the risk of data loss and to maximize data accessibility.
While the open-science-data movement long predates the Internet, the availability of fast, ubiquitous networking has significantly changed the context of Open science data, since publishing or obtaining data has become much less expensive and time-consuming.
The Human Genome Project was a major initiative that exemplified the power of open data. It was built upon the so-called Bermuda Principles, stipulating that: "All human genomic sequence information (…) should be freely available and in the public domain in order to encourage research and development and to maximize its benefit to society'.More recent initiatives such as the Structural Genomics Consortium have illustrated that the open data approach can also be used productively within the context of industrial R&D.
In 2004, the Science Ministers of all nations of the Organisation for Economic Co-operation and Development (OECD), which includes most developed countries of the world, signed a declaration which essentially states that all publicly funded archive data should be made publicly available.Following a request and an intense discussion with data-producing institutions in member states, the OECD published in 2007 the OECD Principles and Guidelines for Access to Research Data from Public Funding as a soft-law recommendation.

There are a range of different arguments for government open data.For example, some advocates contend that making government information available to the public as machine readable open data can facilitate government transparency, accountability and public participation. "Open data can be a powerful force for public accountability—it can make existing information easier to analyze, process, and combine than ever before, allowing a new level of public scrutiny." Governments that enable public viewing of data can help citizens engage within the governmental sectors and "add value to that data."
Some make the case that opening up official information can support technological innovation and economic growth by enabling third parties to develop new kinds of digital applications and services.
Several national governments have created websites to distribute a portion of the data they collect. It is a concept for a collaborative project in the municipal Government to create and organize culture for Open Data or Open government data.
Additionally, other levels of government have established open data websites. There are many government entities pursuing Open Data in Canada. Data.gov lists the sites of a total of 40 US states and 46 US cities and counties with websites to provide open data; e.g. the state of Maryland, the state of California, USand New York City.
At the international level, the United Nations has an open data website that publishes statistical data from member states and UN agencies,and the World Bank published a range of statistical data relating to developing countries. The European Commission has created two portals for the European Union: the EU Open Data Portal which gives access to open data from the EU institutions, agencies and other bodies and the PublicData portal that provides datasets from local, regional and national public bodies across Europe.
In October 2015, the Open Government Partnership launched the International Open Data Charter, a set of principles and best practices for the release of governmental open data formally adopted by seventeen governments of countries, states and cities during the OGP Global Summit in Mexico.
Many non-profit organizations offer more or less open access to their data, as long it does not undermine their users', members' or third party's privacy rights. In comparison to for-profit corporations, they do not seek to monetize their data. OpenNWT launched a website offering open data of elections.CIAT offers open data to anybody, who is willing to conduct big data analytics in order to enhance the benefit of international agricultural research. DBLP, which is owned by a non-profit organization Dagstuhl, offers its database of scientific publications from computer science as open data. Non-profit hospitality exchange services offer trustworthy teams of scientists access to their anonymized data for publication of insights to the benefit of humanity. Before becoming a for-profit corporation in 2011, Couchsurfing offered 4 research teams access to its social networking data. In 2015, non-profit hospitality exchange services Bewelcome and Warm Showers provided their data for public research.

The debate on open data is still evolving. The best open government applications seek to empower citizens, to help small businesses, or to create value in some other positive, constructive way. Opening government data is only a way-point on the road to improving education, improving government, and building tools to solve other real world problems. While many arguments have been made categorically[ citation needed ], the following discussion of arguments for and against open data highlights that these arguments often depend highly on the type of data and its potential uses.
Arguments made on behalf of open data include the following:
It is generally held that factual data cannot be copyrighted.However, publishers frequently add copyright statements (often forbidding re-use) to scientific data accompanying publications. It may be unclear whether the factual data embedded in full text are part of the copyright.
While the human abstraction of facts from paper publications is normally accepted as legal there is often an implied restriction on the machine extraction by robots.
Unlike open access, where groups of publishers have stated their concerns, open data is normally challenged by individual institutions.[ citation needed ] Their arguments have been discussed less in public discourse and there are fewer quotes to rely on at this time.
Arguments against making all data available as open data include the following:
The goals of the Open Data movement are similar to those of other "Open" movements.
Several funding bodies which mandate Open Access also mandate Open Data. A good expression of requirements (truncated in places) is given by the Canadian Institutes of Health Research (CIHR):
Other bodies active in promoting the deposition of data as well as full text include the Wellcome Trust. An academic paper published in 2013 advocated that Horizon 2020 (the science funding mechanism of the EU) should mandate that funded projects hand in their databases as "deliverables" at the end of the project, so that they can be checked for third party usability then shared.
Several mechanisms restrict access to or reuse of data (and several reasons for doing this are given above). They include:
Open content describes any work that others can copy or modify freely by attributing to the original creator, but without needing to ask for permission. This has been applied to a range of formats, including textbooks, academic journals, films and music. The term was an expansion of the related concept of open-source software. Such content is said to be under an open licence.
Research is "creative and systematic work undertaken to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." It involves the collection, organization, and analysis of information to increase our understanding of a topic or issue. At a general level, research has three steps: 1. Pose a question. 2. Collect data to answer the question. 3. Present an answer to the question. This should be a familiar process. You engage in solving problems every day and you start with a question, collect some information, and then form an answer. Research is important for three reasons.1. Research adds to our knowledge: Adding to knowledge means that educators undertake research to contribute to existing information about issues 2.Research improves practice: Research is also important because it suggests improvements for practice. Armed with research results, teachers and other educators become more effective professionals. 3. Research informs policy debates: research also provides information to policy makers when they research and debate educational topics.
In academic publishing, a scientific journal is a periodical publication intended to further the progress of science, usually by reporting new research.
CiteSeerx is a public search engine and digital library for scientific and academic papers, primarily in the fields of computer and information science. CiteSeer is considered as a predecessor of academic search tools such as Google Scholar and Microsoft Academic Search. CiteSeer-like engines and archives usually only harvest documents from publicly available websites and do not crawl publisher websites. For this reason, authors whose documents are freely available are more likely to be represented in the index.
Open access (OA) is a set of principles and a range of practices through which research outputs are distributed online, free of cost or other access barriers. With open access strictly defined, or libre open access, barriers to copying or reuse are also reduced or removed by applying an open license for copyright.
Openness is an overarching concept or philosophy that is characterized by an emphasis on transparency and collaboration. That is, openness refers to "accessibility of knowledge, technology and other resources; the transparency of action; the permeability of organisational structures; and the inclusiveness of participation". Openness can be said to be the opposite of closedness, central authority and secrecy.
Open educational resources (OER) are freely accessible, openly licensed text, media, and other digital assets that are useful for teaching, learning, and assessing as well as for research purposes. There is no universal usage of open file formats in OER.
The English adjective free is commonly used in one of two meanings: "for free" (gratis) and "with little or no restriction" (libre). This ambiguity of free can cause issues where the distinction is important, as it often is in dealing with laws concerning the use of information, such as copyright and patents.
PubMed Central (PMC) is a free digital repository that archives open access full-text scholarly articles that have been published within the biomedical and life sciences journal literature. As one of the major research databases within the suite of resources that have been developed by the National Center for Biotechnology Information (NCBI), PubMed Central is much more than just a document repository. Submissions into PMC undergo an indexing and formatting procedure which results in enhanced metadata, medical ontology, and unique identifiers which all enrich the XML structured data for each article on deposit. Content within PMC can easily be interlinked to many other NCBI databases and accessed via Entrez search and retrieval systems, further enhancing the public's ability to freely discover, read and build upon this portfolio of biomedical knowledge.
Grey literature are materials and research produced by organizations outside of the traditional commercial or academic publishing and distribution channels. Common grey literature publication types include reports, working papers, government documents, white papers and evaluations. Organizations that produce grey literature include government departments and agencies, civil society or non-governmental organizations, academic centres and departments, and private companies and consultants.
Open science is the movement to make scientific research and its dissemination accessible to all levels of an inquiring society, amateur or professional. Open science is transparent and accessible knowledge that is shared and developed through collaborative networks. It encompasses practices such as publishing open research, campaigning for open access, encouraging scientists to practice open notebook science, and generally making it easier to publish and communicate scientific knowledge.
Free content, libre content, or free information, is any kind of functional work, work of art, or other creative content that meets the definition of a free cultural work.
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 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.
An open-access mandate is a policy adopted by a research institution, research funder, or government which requires researchers—usually university faculty or research staff and/or research grant recipients—to make their published, peer-reviewed journal articles and conference papers open access (1) by self-archiving their final, peer-reviewed drafts in a freely accessible institutional repository or disciplinary repository or (2) by publishing them in an open-access journal or both.
Open science data is a type of open data focused on publishing observations and results of scientific activities available for anyone to analyze and reuse. A major purpose of the drive for open data is to allow the verification of scientific claims, by allowing others to look at the reproducibility of results, and to allow data from many sources to be integrated to give new knowledge. While the idea of open science data has been actively promoted since the 1950s, the rise of the Internet has significantly lowered the cost and time required to publish or obtain data.
A memory institution is an organization maintaining a repository of public knowledge, a generic term used about institutions such as libraries, archives, heritage institutions, aquaria and arboreta, and zoological and botanical gardens, as well as providers of digital libraries and data aggregation services which serve as memories for given societies or mankind. Memory institutions serve the purpose of documenting, contextualizing, preserving and indexing elements of human culture and collective memory. These institutions allow and enable society to better understand themselves, their past, and how the past impacts their future. These repositories are ultimately preservers of communities, languages, cultures, customs, tribes, and individuality. Memory institutions are repositories of knowledge, while also being actors of the transitions of knowledge and memory to the community. These institutions ultimately remain some form of collective memory. Increasingly such institutions are considered as a part of a unified documentation and information science perspective.
A copyright transfer agreement or copyright assignment agreement is an agreement that transfers the copyright for a work from the copyright owner to another party. This is one legal option for publishers and authors of books, magazines, movies, television shows, video games, and other commercial artistic works who want to include and use a work of a second creator: for example, a video game developer who wants to pay an artist to draw a boss to include in a game. Another option is to license the right to include and use the work, rather than transferring the copyright.
Library Genesis (Libgen) is a file-sharing website for scholarly journal articles, academic and general-interest books, images, comics, and magazines. In part, the site enables free access to content that is otherwise paywalled or not digitized elsewhere. Libgen describes itself as a "links aggregator" providing a searchable database of articles, books, and images "collected from publicly available public Internet resources", as well as uploaded "items from users".
The idea and practise of providing free online access to journal articles began at least a decade before the term "open access" was formally coined. Computer scientists had been self-archiving in anonymous ftp archives since the 1970s and physicists had been self-archiving in arxiv since the 1990s. The Subversive Proposal to generalize the practice was posted in 1994.
Open source products include permission to use the source code, design documents, or content of the product. It most commonly refers to the open-source model, in which open-source software or other products are released under an open-source license as part of the open-source-software movement. Use of the term originated with software, but has expanded beyond the software sector to cover other open content and forms of open collaboration.
