In Zürich there are two hackathons with themes & participants from the open data community: FinTech @ Schiffbau and Dada Data @ Cabaret Voltaire.
An open data community meet-up will take place on Saturday afternoon, from approximately 15:15:15 at Impact Hub Zürich. Join us in person!
Or join us virtually! We would be happy to hear about your projects and collect Open Data related announcements here: https://pad.okfn.org/p/opendataday-ch-2016
