BarCamp is an international network of "unconferences" (open, participatory events, the schedule and content are determined by the participants), on topics such as Web applications at an early stage, open source technologies and social software. The name is a reference to a series of events initiated by Tim O'Reilly called FooCamp and also refers to the concept of Foobar. BarCamps are mainly organized in wikis and advertised. The "open sourcing" of the organizational process and the open nature of the event has helped her in a short time to great success. Since the first BarCamp in Palo Alto (California) in August 2005 in the premises of the company Socialtext have already been held in 44 cities in North America, Asia and Europe BarCamp. Timing of BarCamp has similarities to the Open Space method is, however, organized loosely . It consists of lectures and discussions, which are coordinated at the whiteboard every morning by the participants themselves. But there are rules: All participants are required to keep themselves a lecture or organize and also collect information and experience from the event via channels such as blogs, photo sharing, social bookmarking, wikis and IRC. Participation is free and only for reasons of space limited, prior registration is therefore necessary. The cost of the event and for meals will be from sponsors.
