The document discusses the THOR project, which aims to place Persistent Identifiers (PIDs) at the fingertips of researchers and integrate them into existing research services and outputs. The goals are to uniquely attribute work to researchers and make PID use the default across the research lifecycle. The project focuses on biological sciences, earth sciences, physical sciences, social sciences, and humanities. It provides examples of how PIDs can improve credit for researchers, discoverability and reuse of data and publications, demonstrate value for data centers, improve evidence for publishers, and measure impact for funders.
