There is a lot going on in the Nordics related to APIs and Open Data. In Norway Travelhack 2014 Norge has already started, but it is not too late to join.
TravelHack is a competition that challenges student, community and commercial teams to design new digital service prototypes based on open data to be used by people when travelling with public transportation in Norway! The teams should select one or several developed persona and develop their services for this user group. The contest will end with a hackathon on May 9-10 at NSB Competence Centre in Drammen. Prizes include travel passes and mentorship in open data provided by NSB (Norwegian State Railways).
If you are organizing a hackathon or some other event that would be interesting to the Nordic APIs community then please let us know. We would be glad to promote your event.
