DOI Resource

Internationaldoi

Description

A DOI name for any resource. The prefix (10.NNNN) names the registrant; the suffix is registrant-defined — an opaque string, a journal-style path (10.1006/jmbi.1998.2354), or an SDO designation (NIST.SP.800-53r5).

Syntax

DOI syntax is "doi:10.{prefix}/{suffix}" (case-insensitive scheme, normalized to lowercase). PubID accepts the canonical "doi:" form, the bare "10.x/suffix" name, the "DOI:" upper-scheme spelling, and the resolver-URL form on the doi.org host — all render canonical.

Components Used

DOI DOI Resource identifiers are composed of these elements:

Scheme

Enumeration

The "doi:" scheme token

doi:

Case-insensitive on parse (DOI: accepted); rendered lowercase

e.g.doi:

Prefix

String

The registrant prefix, always beginning 10.

10.{NNNN} — 4+ digits naming the registrant

e.g.10.6028

:prefix

Suffix

String

The registrant's opaque resource suffix

Any string; SDO designations use dotted series (NIST.SP.800-53r5)

e.g.NIST.2022-04-15.001

:suffix

Algebraic Relations

Relations that can involve DOI Resource identifiers:

Relation	Description	Syntax	Example
URL form	The resolver URL parses and renders as the canonical DOI name	`doi.org/10.{prefix}/{suffix}`	`https://doi.org/10.1000/182`
