The 2020 Edition of the Swiss Open Cultural Data Hackathon will take place on 5-6 June as an ONLINE hackathon. This edition is virtually hosted by the Swiss Institute for Information Science at the FHGR Chur, in collaboration with the Institute for Multimedia Production. The focus of the GLAMhack will be on Linked Open Data, Machine Learning, Human-Computer-Interaction and Crowdsourcing. Once again, we are happy to collaborate with Wikimedia CH, infoclio.ch and other members of the Friends of OpenGLAM Network. See make.opendata.ch for the detailed program.
