Open science has been firmly on the agenda in the Netherlands in the last couple of years. It has been a priority for the previous and current government. In the Coalition Agreement 2017-2021 the government states that `Open Science and Open Access will become the norm in academic research’.1 The motto here is: ad open as possible, ad closed as necessary. The switch to open science requires ambition, investment in people and resources, and being alert to any risks. On open science and open access the government of the Netherlands works closely together with national and international stakeholders.
