Open Collaboration is a pattern of collaboration, innovation, and production. It was observed prominently in open source software, but can also be found in many other instances, such as in internet forums, mailing lists and internet communities. Open Collaboration is also thought to be the operating principle underlining a gamut of diverse ventures, including BitCoin, TEDx, and Wikipedia.
The first scientific peer-reviewed study of Open Collaboration defines it as "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."  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 Wikipedia, or in 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.
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. Open Collaboration is also thought to be the operating principle underlining a gamut of diverse ventures, including BitCoin, TEDx, and Wikipedia. It also explains some instances of Crowdsourcing, Collaborative Consumption, and Open Innovation.
An annual conference dedicated to the research and practice of open collaboration is the International Symposium on 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)."
