Many repositories already use persistent identifiers (PIDs) such as ORCID iDs for individuals and DOIs for research outputs to better understand research activity and to make research information more Findable, Accessible, Interoperable, and Reusable (FAIR). However, until recently, there has been no standardized, interoperable way to connect these elements from the perspective of an overarching research project. RAiD (Research Activity Identifier), an international standard and system for identifying research projects (ISO 23527:2022), was established in 2022 by the Australian Research Data Commons (ARDC) to address this gap. RAiD can be used alongside existing PIDs to more effectively identify, track, and share information about research projects and their associated outputs. RAiD is already established in Australia, where research organizations have been investigating the use of RAiD in their repositories to meet funder requirements. As part of the United States (US) RAiD Pilot, multiple universities are testing the integration of RAiD into their repository workflows. This session aims to provide an introduction to RAiD and share initial findings from recent RAiD adoption efforts to offer recommendations and insights for repositories interested in adopting RAiD.
