Funded by the National Science Foundation’s FAIR Open Science (FAIROS) program, this project is a Research Coordination Network (RCN) collaboration between the NSF National Center for Atmospheric Research, University of Colorado Boulder, and Florida State University. The project promotes community-wide discussions and encourages the adoption of best practices that recognize the large variability in persistent identifier (PID) implementations for research facilities and instrumentation. To build on intensive discussions established during the first two years of the project, the FAIR Facilities and Instruments RCN hosted its third in-person workshop at the NSF National Center for Atmospheric Research, in Boulder, CO, on September 22-24, 2025. Fifty individuals from academic institutions, national laboratories, nonprofit organizations, and private industry participated in discussions on progress and lessons learned, practical challenges and tracking PIDs, engaging with stakeholders not present in conversations to date, and identifying ways forward for a PID strategy. Discussions at the workshop specifically focused on a draft "Recommendations for FAIR Facilities and Instruments" that was circulated to all attendees before the workshop. Key outcomes included insights on how to improve the recommendations and on general takeaways related to PIDs for research facilities and instruments.
