Some reflections on the current PID landscape – with an emphasis on risks and trust issues

The current landscape around persistent identifiers (PIDs) keeps quickly evolving. Some PIDs like Digital Object Identifiers (DOIs) for publications and datasets or ORCIDs (Open Researcher and Contributor ID) for persistent author identification are already well-established, but there is also a whole additional range of emerging identifiers in the research area, often being implemented under competing approaches. These include among others identifiers for organisations (OrgIDs), for research grants (grantIDs), and projects (RAIDs), for research equipment and facilities (PIDINSTs) and for physical samples (IGSNs).
