as the organisers put it
We believe that the community and the open-source models are well suited for our core values:learning, teaching and knowledge sharing. Our mission is to inspire other communities with the concept of open-source events.We’re publishing all data about this conference, in full transparency. We are also available at any time for inquires and we`re really looking forward to sharing our knowledge about organizing international events. This way, whenever a community wants to start something similar, they can build on our knowledge.
