The Barcamp Open Science is a barcamp dedicated to the Open Science movement. It is open to everybody interested in discussing, learning more about, and sharing experiences on practices in Open Science. We would like to invite researchers and practitioners from various backgrounds to contribute their experience and ideas to the discussion. The barcamp will bring together both novices and experts and its open format supports lively discussions, interesting presentations, development of new ideas, and knowledge exchange. Though, previous knowledge on Open Science is not mandatory. The barcamp is open to all topics around Open Science that the participants like to discuss.
