This poster presents re3data as a global, interdisciplinary registry of research data repositories and highlights the role of persistent identifiers (PIDs) in strengthening operation and reuse. It shows how PIDs support internal registry curation by improving data quality, consistency, interoperability, querying, deduplication, and metadata enrichment. The poster also demonstrates how PID-enabled registry metadata increases the value of re3data in external contexts by enabling unambiguous identification, linking and combining information across systems, supporting integration into scholarly workflows, and facilitating analytics, assessment, and long-term attribution. In doing so, it demonstrates the importance of PIDs for registry operation.
