Research data play a central role in research. Researchers in general recognise the importance of good data management practices and the sharing of research data, to ensure the integrity of research and to advance science for the benefit of society. At an individual level they may struggle to share their data or to spend time and resources on data management. Experiences from the UK show that research integrity, data openness and good data practices can be boosted through a framework of policies, data infrastructure, data services and training. The UK Data Archive’s practical guidance, training and tools for research data management will be showcased, with particular attention for the ethical and legal challenges in managing and sharing data in research with human participants.
