Data management planning (DMP) concerns the development, execution and supervision of plans, policies, programs and practices that control, protect, deliver and enhance the value of data and information assets. The certification of digital repositories (the subject of D13.4) is an important instrument to improve the quality of the data management infrastructure. Both DMP and certification of repositories are closely related and covered in this report. This deliverable contains the strategy and planning to create and disseminate expertise on DMP for the EHRI community. Input from the research data community on DMP is discussed with and assessed by policy makers from IT-savvy EHRI partners. This input consists of the FAIR data principles, the certification of repositories by means of a certification framework, the data management services provided by the EUDAT Collaborative Data Infrastructure, and the current relevant practices of the invited partners as well as the Dutch National Archives. All these will be used as building blocks for the final roadmap for a long-term access infrastructure of Holocaust digital objects (D13.2).
