In this talk, we overview the outcome of the "Enhancing interoperability through the use of PIDs in research platforms" project, which involved a collaboration between research tool providers and institutions to clarify, design, and implement IGSN IDs for material samples into the RSpace Inventory system, by integrating with DataCite’s DOI API. We focus on the practical challenges encountered: navigating close communication between multiple parties with varied backgrounds, such as gaps in conceptual knowledge around PIDs, differences in terminology used, and a lack of a clear framework for identifying the ideal allocation of responsibilities and roles within the PID workflow.
