In the hope of informing future decisions regarding the use of persistent identifiers (PID) in the common European data space for cultural heritage, we have conducted an analysis of the usage of PIDs in the metadata that cultural heritage institutions deliver to Europeana.eu. Our analysis focuses on the persistent identification of cultural heritage objects and their digital representations, and we have analysed the usage of five PID schemes: Archival Resource Key (ARK), Digital Object Identifier (DOI), HANDLE, Persistent URL (PURL), and Uniform Resource Name (URN).
This lightning talk presents some statistics of PID usage in Europeana.eu, which show that 13% of the records in Europeana.eu contain a PID and that ARK and HANDLE are the most frequently used PID schemes. We have also analysed the uniqueness of the existing PIDs, and identified some data quality issues.
