Overviews & Standards
The following materials provide high-level, introductory discussion about DOI® names; detailed coverage of policy, operations and technology; and a description of the components of the DOI® System and its underlying technology.
DOI System
1. Key Facts
2. System Descriptions
An
article on the DOI System by Norman Paskin, revised March 2009, for the (forthcoming, 2010) third edition of the
Encyclopedia of Library and Information Sciences, Taylor & Francis Group. [PLEASE NOTE: The pre-publication proof provided here for information only is not paginated and not yet published; it should not be used for citation purposes.]

The DOI® System is currently being standardised through the International Standards Organisation, ISO. The Draft International Standard ISO/DIS 26324, Information and documentation Digital Object Identifier System (prepared by ISO/TC 46/SC 9) met the ISO requirements for approval. The relevant ISO Working Group has now submitted an edited version to ISO for distribution as an FDIS (Final Draft International Standard) ballot.
The FDIS ballot runs for 2 months; ISO is allowed up to 3 months to process the FDIS submittal prior to issuing the ballot including obtaining the required French translation. So it may take as much as 5 months from the time we submit the FDIS to when the ballot actually ends and publication is made. Beyond the FDIS ballot there are no further normal processes re voting, and the standard will issue. Following preparation of the FDIS, the DOI Handbook will be revised to reflect its additional role as the User Manual for this ISO standard.
For further information, please contact the convenor of the ISO Working Group: Norman Paskin (n.paskin@doi.org). See also the DOI System
overview article, which incorporates material from the draft standard.
2. Internet Engineering Task Force (IETF) Request For Comments (RFC)
The DOI System is an implementation of the
Handle System. There are three Handle System RFCs:
Sun, Sam; Lannom, Larry; Boesch, Brian. "Handle System Overview". RFC 3650, November 2003.
Sun, Sam; Reilly, Sean; Lannom, Larry. "Handle System
Namespace and Service Definition". RFC 3651, November 2003.
Sun, Sam; Reilly, Sean; Lannom, Larry; Petrone, Jason. "Handle System Protocol (Ver 2.1) Specification". RFC 3652, November 2003.
4. ISO/IEC MPEG21 Standards
DOI names use a semantic data dictionary and the IDF is the formal
Registration Authority of the MPEG21 Rights Data dictionary. For further information on the RDD please send a request to contact@doi.org. For information on MPEG, see the
MPEG website.
5. NISO Standards
1. Handle System
DOI names are an implementation of the
CNRI Handle System®, in which the term "DOI" is used instead of "handle" to describe the identifiers. For more information on the role of the Handle System in the DOI System, see the Factsheet "
DOI System and Handle".
The Handle System web site includes an overview of the Handle System, definition of the namespace, and protocol specification which have been published as
IETF Informational RFCs. Also of interest to the community is a discussion of Handle System
scalability and an explanation of
handle resolution. (See also the DOI
® Handbook, Chapter 3,
Resolution.)
CNRI and ITU recently entered into an agreement to collaborate on use of the Handle System and the Digital Object Architecture (which Handle System is part of) more generally, and are working on the specific details of that collaboration. ITU has listed the Handle System as an "emerging trend":

2. Indecs Data Dictionary
DOI names use a semantic data dictionary, the indecs data dictionary, which is based on work including the original indecs project and its further development into the MPEG21 Rights Data dictionary. For more information on the role of the Data Dictionary in the DOI System, see the Factsheet "
DOI System and data dictionaries".
