EU Open Data Days attract 247 proposals!

The call for submissions of proposals, closed on 21 May 2021, has attracted 247 proposals for both parts of the event, with 151 proposals to shape the programme of EU DataViz and 96 ideas for open data applications to compete in EU Datathon. The proposals are now being evaluated by the two Programme Committees and the contributors will be notified about the results in the course of June and July, respectively.

Looking at the geographical origins of the submissions, they come from across Europe and far beyond, representing 47 countries, including 24 EU Member States. The represented sectors are equally diverse, covering the private sector as the one most represented, followed by academia and the public sector. Building on such diversity, the first EU Open Data Days promise for an inspiring and highly relevant event for all segments of the society.
