#REDIRECT [[Free content]]
'''Open content''', a [[neologism]] coined by analogy with "[[open source]]", describes any kind of [[creative work]], or [[Content (media and publishing)|content]], published in a format that explicitly allows copying and modifying of its information by anyone, not exclusively by a closed organization, firm or individual. The largest open content project is [[Wikipedia]].<ref>{{cite web |url=http://www.abo.psychologie.uni-wuerzburg.de/virtualcollaboration/publications.php?action=view&id=44 |title=Voluntary Engagement in an Open Web-based Encyclopedia: Wikipedians, and Why They Do It |last=Schoer |first=Joachim |coauthors=Hertel, Guido |date=2007-12-03 |publisher[[University of Würzburg]] |format=PHP |accessdate=2007-03-17}}</ref>

{{R from alternative name}}

{{R from merge}}
The [[Open Knowledge Foundation]] has undertaken work on a technical definition for open content. The Open Knowledge Definition (OKD) gives a set of conditions for openness in knowledge - much as the [[Open Source Definition]] does for [[open-source software]]. Content can be either in the [[public domain]] or under a [[license]] which allows re-distribution and re-use, such as [[Creative Commons]] Attribution and Attribution-Sharealike licenses or the [GNU Free Documentation License ] (GFDL). It is worth noting that the OKD covers open data as well as open content.

==History==
It is possible that the first documented case of open content was the [[Royal Society]], which aspired to share information across the globe as a public enterprise.{{Fact|date=April 2008}} The term "open content" was first used in the modern context by [[David A. Wiley|David Wiley]], then a graduate student at [[Brigham Young University]], who founded the [[Open Content Project]] and put together the first content-specific (non-software) license in 1998, with input from [[Eric S. Raymond|Eric Raymond]], [[Tim O'Reilly]], and others.{{Fact|date=April 2008}}

== Free content ==
{{main|free content}}
As with [[alternative terms for free software|the terms "open source" and "free software"]], some open content materials can also be described as "[[free content]]", although technically they describe different things. For example, the [[Open Directory Project]] is open content but is not free content. The main difference between licenses is the definition of ''freedom'': some licenses attempt to maximize the freedom of all potential recipients in the future (by having minor "restrictions") while others maximize the freedom of the initial recipient.

===Common content===
The related term "common content" is occasionally used to refer to [[Creative Commons]]–licensed works. This takes after<!-- ?? --> the [[Common Content]] project, which is an attempt to collect as many such works as possible.

===Open access===
"[[Open access (publishing)|Open access]]" refers to a special category of material, consisting of freely available published [[Peer review|peer-reviewed]] journal articles.

==Open-content search engines==
{{Expand-section|date=April 2008}}
With the increased interest in open content, many universities have started offering online video/audio courses to the general public, such as [[Massachusetts Institute of Technology]] and [[Princeton University]]. This has resulted in a great increase in providers of open content. The difficulty of keeping track of all such content had led to the birth of open-content search engines.<ref name="ccsearch">{{cite web |url=http://search.creativecommons.org/ |accessdate=2008-08-09 |publisher=[[Creative Commons]] |title=Creative Commons meta-search engine}}</ref>
