A Data Management Plan helps achieve optimal handling, organising, documenting and enhancing of research data. It is particularly important for facilitating data sharing, ensuring the sustainability and accessibility of data in the long-term and allowing data to be reused for future research. For the effective management of data, planning must start when research is being designed and needs to consider both how data will be managed during the research and how they will be shared afterwards. This document includes presentation slides from the Day 1 of the event.
