Standardization
The DOI system is an international standard developed by the International Organization for Standardization in its technical committee on identification and description, TC46/SC9. The Draft International Standard ISO/DIS 26324, Information and documentation - Digital Object Identifier System met the ISO requirements for approval. The relevant ISO Working Group later submitted an edited version to ISO for distribution as an FDIS (Final Draft International Standard) ballot, which was approved by 100% of those voting in a ballot closing on November 15, 2010. The final standard was published on April 23, 2012.
DOI is a registered URI under the infoURI specification (IETF RFC 4452), "The "info" URI Scheme for Information Assets with Identifiers in Public Namespaces"; info:doi/ is the infoURI Namespace of Digital Object Identifiers.
The DOI syntax is a NISO standard, first standardised in 2000, ANSI/NISO Z39.84-2005 Syntax for the Digital Object Identifier.
