“At the European Open Science Cloud (EOSC) Summit in June 2017, I made a commitment to champion the alignment of research data management (RDM) among research funding organisations in Europe. This commitment was the origin of an initiative for that purpose, launched by Science Europe and the Netherlands Organisation for Scientific Research (NWO) in January 2018. The aim of the initiative was to develop a set of core requirements for data management plans (DMPs), as well as a list of criteria for the selection of trustworthy repositories where researchers can store their data for sharing. In light of the development of the EOSC and an increasing tendency towards data sharing, these requirements and criteria should help to harmonise rules on data management throughout Europe. This will aid researchers in complying with RDM requirements even when working with different research funders and research organisations. Less than a year after its launch, I am pleased to introduce the results of this endeavour. These core requirements for DMPs and criteria for the selection of trustworthy repositories have been developed by experts from Science Europe‚Äôs Member Organisations, who have sought additional input from external stakeholders to ensure a broad consensus….”
