Editorial commentary
A PID provider is the organisation standing behind a persistent identifier: it mints (or delegates minting of) identifiers under a scheme, operates or contracts the resolution infrastructure that makes them dereferenceable, and makes an explicit or implicit long-term commitment to keep both the identifier and its metadata usable. “Provider” describes the actor; PID minting and PID resolution describe what that actor does.
Who counts as a provider
Crossref and DataCite are DOI registration agencies — they mint DOIs on behalf of member publishers and repositories under the Handle System operated by CNRI. ORCID Inc. is a single, centralised provider for the ORCID iD scheme. ROR is jointly operated by the California Digital Library, Crossref, and DataCite. ARK Name Assigning Authority Number (NAAN) holders — often national libraries or research institutions — are a deliberately distributed provider model: anyone can request a NAAN and become a provider without paying a central registration fee, contrasting with the DOI registration-agency model. National libraries running local URN:NBN resolvers are providers in the same sense.
Why the provider distinction matters
A provider’s persistence policy — its public statement of what happens to already-issued identifiers if the organisation is dissolved, merges, or stops funding the resolver — is a core part of an identifier scheme’s real-world trustworthiness, distinct from the technical soundness of the scheme’s syntax or resolution protocol. This is the identifier-infrastructure analogue of what trusted digital repository certification (CoreTrustSeal) assesses for data repositories: an organisational commitment layered on top of a technical one. A scheme with many independent, federated providers (ARK) is resilient to any single provider’s failure; a scheme with one centralised provider (ORCID) concentrates that risk in a single organisation’s continuity, which is why ORCID’s own governance and consortium structure (see ORCID consortium) is itself a matter of public record.
