LinuxTag (the name is a compound with the German Tag meaning assembly, conference or meeting) is a free software exposition with an emphasis on Linux (but also BSD), held annually in Germany. LinuxTag claims to be Europe's largest exhibition for "open source software" and aims to provide a comprehensive overview of the Linux and free software market, and to promote contacts between users and developers. LinuxTag is one of the world's most important events of this kind.
LinuxTag's slogan, "Where .COM meets .ORG", refers to its stated aim of bringing together commercial and non-commercial groups in the IT sector. Each year's event also has its own subtitle.
Promotion of free softwareEdit
LinuxTag sees itself as part of the free software movement, and promotes this community in an extraordinary degree by supporting numerous open source projects. LinuxTag offers a way for these projects to promote their software and their concepts, and thus present themselves to the public in an appropriate manner, with their own stands, forums and lectures. The goal is to encourage projects to share concepts and content to the benefit of other groups and companies, and to provide forums for in-depth discussions of new technologies and opportunities.
The non-profit association "LinuxTag e.V." was founded in preparation for LinuxTag's move from Kaiserslautern to the University of Stuttgart in 2000. The association plans and organizes the LinuxTag event by volunteer work and guides its ideological development. The association LinuxTag e.V. is registered in Association Register VR 2239 of the Kaiserslautern District Court. The association manages the LinuxTag name and word mark. The purpose of the association, according to its bylaws, is "the promotion of Free Software", and is pursued through the organization of the LinuxTag events.
The association is represented by a three-person executive board, supplemented by several representatives with delegated authority. All members of the LinuxTag association are volunteers and receive no remuneration for their service. (In 2005, the First Chairman and CFO were employed and remunerated by the association from 1 April until 31 July.) Surpluses resulting from the LinuxTag events or from sponsorship are reinvested in the association's non-profit activities.
LinuxTag was launched in 1996 by a handful of active members of the Unix Working Group (Unix-AG) at the University of Kaiserslautern.
