Editorial commentary
The DOI suffix is the registrant’s degree of freedom. It can be a human-meaningful string (e.g. 10.1234/journal.2024.01.005 reflecting journal/year/issue/page), an opaque sequence (e.g. 10.5281/zenodo.4317001), or a UUID. DOI suffix syntax restrictions are minimal (any printable Unicode, subject to URL-percent-encoding rules and case-insensitivity); registrants are encouraged to keep suffixes opaque, short, and free of embedded semantics that may become misleading over time.
