This is the first of a six-part online programme, bringing together funders, publishers, infrastructure providers, researchers, and research professionals to drive coordinated cross-sector action and make open research a reality in the UK. This session explores research data planning and review, focusing on the upstream practices that shape how research data and materials are managed, shared, and reused across the research lifecycle. Using the recent Sustainable and TrAnsparent Research data (STAR) Study Report as a starting point, this session will bring together perspectives from across the sector to reflect on the report’s recommendations, paying particular attention to its concluding recommendation on the need for formalised open research review mechanisms.
