The document describes Project THOR, a 30 month H2020 project aiming to connect people, places, and things through Persistent Identifiers (PIDs). The goals are to place PIDs at researchers' fingertips by integrating them into existing research services, and ensure PIDs are embedded in research outputs across various focus areas like biology, earth sciences, and social sciences. Project THOR will establish interoperability between PID infrastructures, develop services to capture PIDs and ORCIDs, and stimulate PID implementation through outreach events and training materials.
