Funders want researchers to 1) deposit the relevant data from their research in an approved repository to make it FAIR (Findable, Accessible, Interoperable, Reusable), 2) make the data openly available whenever possible, and 3) write a Data Management Plan describing how they will manage their data during and after the project. Funders require depositing data in repositories to enable reuse, making data open access "as open as possible, as closed as necessary", and having a Data Management Plan that addresses reuse according to FAIR principles.
