Schweizerischer Nationalfonds SNF
Since 2017 The Swiss National Science Foundation requires most projects to add a data management plan to any application for funding. See SNF - Open Research Data
As part of the overall Horizon 2020 plan, one of the EU’s main strategic aims is to foster open data in scientific practice. In order to apply for funding, a data management plan has to be submitted.
Other funders, journals
Increasingly other funders as well as publishers will demand data management plans and access to data as prerequisites for funding or publishing. Open data are becoming part of practicing good science.
