<strong>Open data is data that can be freely used, shared and built-on by anyone, anywhere for any purpose</strong>. This is the summary of <a href="http://opendefinition.org/okd/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">the full Open Definition</a> which <a href="http://okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">the Open Knowledge Foundation</a> created in 2005 to provide both a succinct explanation and a detailed definition of <a href="http://okfn.org/opendata" style="color:rgb(62,143,128);text-decoration:none" target="_blank">open data</a>.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">As the open data movement grows, and even more governments and organisations sign up to open data, it becomes ever more <strong>important that there is a clear and agreed definition</strong> for what “open data” means if we are to realise the full benefits of openness, and avoid the risks of creating incompatibility between projects and splintering the community.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)"><img src="http://assets.okfn.org/images/ok_buttons/od_640x120_blue.png" width="640" height="120" style="min-height:auto;max-width:100%;vertical-align:middle;border:0px"></p>

Anyone can release their data under an open licence for free use by and benefit to the public. Although we may think mostly about government and public sector bodies releasing public information such as budgets or maps, or researchers sharing their results data and publications, any organisation can open information (corporations, universities, NGOs, startups, charities, community groups and individuals).</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">There is open information in <a href="http://transport.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">transport</a>, <a href="http://science.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">science</a>, <a href="http://product-open-data.com/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">products</a>, <a href="http://education.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">education</a>, <a href="http://sustainability.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">sustainability</a>, <a href="http://www.openstreetmap.org/#map=5/51.500/-0.100" style="color:rgb(62,143,128);text-decoration:none" target="_blank">maps</a>, <a href="http://legislation.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">legislation</a>, <a href="http://openbiblio.net/principles/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">libraries</a>, <a href="http://openeconomics.net/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">economics</a>, <a href="http://openglam.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">culture</a>, <a href="http://open-development.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">development</a>, <a href="http://opencorporates.com/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">business</a>, <a href="http://design.okfn.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">design</a>, <a href="http://openspending.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">finance</a> …. So the explanation of what open means applies to all of these information sources and types. Open may also apply both to data – big data and <a href="http://blog.okfn.org/2013/04/22/forget-big-data-small-data-is-the-real-revolution/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">small data</a> – or to content, like images, text and music!</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)"><img src="http://assets.okfn.org/images/data-types.png" width="417" height="435" style="min-height:auto;max-width:100%;vertical-align:middle;border:0px"></p>

<h3 style="margin:10px 0px;font-family:OpenSans,'Helvetica Neue',Helvetica,Arial,sans-serif;line-height:30px;color:rgb(51,51,51);font-size:24px;background-color:rgb(245,247,246)">What is Open?</h3><p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">
The <a href="http://opendefinition.org/okd/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">full Open Definition</a> provides a precise definition of what open data is. There are 2 important elements to openness:</p>
<ul style="padding:0px;margin:0px 0px 10px 25px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">
<li><strong>Legal openness</strong>: you must be allowed to get the data legally, to build on it, and to share it. Legal openness is usually provided by applying an appropriate <a href="http://opendefinition.org/licenses/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">(open) license</a> which allows for free access to and reuse of the data, or by placing data into the public domain.</li>
<li><strong>Technical openness</strong>: there should be no technical barriers to using that data. For example, providing data as printouts on paper (or as tables in PDF documents) makes the information extremely difficult to work with. So the Open Definition has various requirements for “technical openness,” such as requiring that data be machine readable and available in bulk.</li>
</ul><p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">There are a few key aspects of <em>open</em> which <a href="http://opendefinition.org/okd" style="color:rgb(62,143,128);text-decoration:none" target="_blank">the Open Definition</a> explains in detail. Open Data is useable by anyone, regardless of who they are, where they are, or what they want to do with the data; there must be no restriction on who can use it, and commercial use is fine too.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">Open data must be available in bulk (so it’s easy to work with) and it should be available free of charge, or at least at no more than a reasonable reproduction cost. The information should be digital, preferably available by downloading through the internet, and easily processed by a computer too (otherwise users can’t fully exploit the power of data – that it can be combined together to create new insights).</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">Open Data must permit people to use it, re-use it, and redistribute it, including intermixing with other datasets and distributing the results.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)"><a href="http://opendefinition.org/okd" style="color:rgb(62,143,128);text-decoration:none" target="_blank">The Open Definition</a> generally doesn’t allow conditions to be placed on how people can use Open Data, but it does permit a data provider to require that data users credit them in some appropriate way, make it clear if the data has been changed, or that any new datasets created using their data are also shared as open data.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">There are 3 important principles behind this definition of <em>open</em>, which are why Open Data is so powerful:</p>

<li><strong>Re-use and Redistribution</strong>: that people can reuse and share the data</li><li><strong>Universal Participation</strong>: that anyone can use the data</li></ul><h3 style="margin:10px 0px;font-family:OpenSans,'Helvetica Neue',Helvetica,Arial,sans-serif;line-height:30px;color:rgb(51,51,51);font-size:24px;background-color:rgb(245,247,246)">
Governance of the Open Definition</h3><p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">Since 2007, the <a href="http://opendefinition.org/advisory-council/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">Open Definition has been governed by an Advisory Council</a>. This is the group formally responsible for maintaining and developing the Definition and associated material. Its mission is to take forward Open Definition work for the general benefit of the open knowledge community, and it has specific responsibility for deciding on what licences comply with the Open Definition.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">The Council is a community-run body. New members of the Council can be appointed at any time by agreement of the existing members of the Advisory Council, and are selected for demonstrated knowledge and competence in the areas of work of the Council.</p>

<a href="http://opendefinition.org/okd/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">The Open Definition</a> was created in 2005 by the Open Knowledge Foundation with input from many people. The Definition was based directly on <a href="http://opensource.org/osd-annotated" style="color:rgb(62,143,128);text-decoration:none" target="_blank">the Open Source Definition</a> from <a href="http://opensource.org/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">the Open Source Initiative</a> and we were able to reuse most of these well-established principles and practices that the free and open source community had developed for software, and apply them to data and content.</p>
<p style="margin:0px 0px 10px;color:rgb(51,51,51);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px;background-color:rgb(245,247,246)">Thanks to the efforts of many translators in the community, the <a href="http://opendefinition.org/okd/" style="color:rgb(62,143,128);text-decoration:none" target="_blank">Open Definition is available in 30+ languages</a>.</p>
