Open Science Fair aims to critically showcase the elements required for the transition to Open Science: e-infrastructures and services, policies as guidance for good practices, research flows and new types of activities, the roles of the respective actors and their networks.

This bianual international conference aims to bring together and empower open science communities and services; to identify common practices related to open science; to see what are the best synergies to deliver and operate services that work for many; and to bring experiences from all around the world and learn from each other.
