How persistent identifiers can save scientists time

Abstract

Research information is useful only if it can be shared – with other researchers, with research organizations (institutions, laboratories, funders, and others), and with the wider community. In our digital age, that means sharing information between data systems. Persistent identifiers (PIDs) provide unique keys for people, places, and things, which enable accurate mapping of information between these systems and supports the research process by facilitating search, discovery, recognition, and collaboration. This article reviews the main PIDs used in research – DOIs for publications, ORCID iDs for researchers, and a proposed new identifier for research organizations – as well as demonstrating how they are being used, and how, in combination, they can increase trust in research and the research infrastructure.
