TIER2, an EU and UKRI-funded project, tackles the reproducibility crisis through eight pilot activities developing practical tools for managing digital research objects across their lifecycle. Aligned with EOSC, it integrates FAIR principles and collaborates with researchers, funders, and publishers to enhance transparency and trust in science. With support from OpenAIRE, TIER2 delivers scalable solutions, such as improved DMPs and monitoring tools, that strengthen Europe’s open and reproducible research ecosystem.
