Editorial commentary
DOIs are issued by Registration Agencies operating under the International DOI Foundation, the principal RAs for research being Crossref (publishers’ content) and DataCite (research data, software, instruments). A DOI is opaque and case-insensitive, with the prefix ’10.NNNN’ and a suffix chosen by the registrant. The DOI Handle System provides resolution; metadata is registered with the issuing RA and exposed via that RA’s APIs. A DOI commits the registrant to keep the identifier resolvable, even if the underlying object is retracted or moved.
