datacite.org

In 2020, the DataCite General Assembly approved the introduction of consortium membership, where a group of like-minded organizations come together to collectively participate in DataCite’s community and governance activities and use DataCite’s DOI services. To limit the gap between the fees for Direct Members and Consortium Organizations and encourage active users to participate in DataCite governance, the fee model included the following provision: 'Consortium Organizations that expect to register more than 10.000 DOIs annually should transfer to Direct Membership within the following calendar year, or pay the additional membership fee (2.000€ annually) while remaining part of the consortium. This ensures that there is appropriate cost recovery based on the impact of cost drivers.'
