Editorial commentary
While ‘persistent identifier’ is the general term across all entity types, ‘persistent data identifier’ specifically denotes PIDs minted for datasets and their parts. The DataCite ecosystem is the dominant infrastructure, but Handle-based repositories (older repositories on Fedora) also issue persistent data identifiers. The Force11 Joint Declaration’s principle 4 (‘Unique Identification’) makes the persistent data identifier the operational anchor of data citation.
