Experts from 47 European research infrastructure initiatives and ERICs have agreed on a set of assertions about the nature, the creation and the usage of Persistent Identifiers (PIDs). This work was done in close synchronisation with the RDA Data Fabric Interest Group (DFIG) ensuring a global validation of the assertions. The intention of this cross-disciplinary report is to overcome still existing confusions about PIDs and the lack of detail knowledge in many disciplines. It is not meant to produce yet another comprehensive document on PIDs, but to identify agreements across documents that have been suggested to be included by experts. With this document GEDE (Group of European Data Experts in RDA Europe) is happy to help demystify PIDs, overcome confusion and create bridges between the various disciplines.
