Current Status• www.doi.org

Founded 1998

• 120 Million DOIs to date
• > 2 billion resolutions per year
• Annual growth rate of 16%• 9 (+) Registration Agencies• 15,000 Registrants• ISO 26324

What it does
• provides a resolvable, persistent, interoperable identifier:• resolvable = standard identifier syntax + network resolution
mechanism• persistent =– technical infrastructure (Handle system, registry database, proxysupport, etc)
– social infrastructure (obligations by Registration Agencies)• interoperable = through a data model (semanticinteroperability)• Links identifier to information and applications

DOI system governanceInternational DOI Foundation www.doi.org
Provides common infrastructure••––Deals with common issues

•
––•
•
•

Technical infrastructure: resolution, data modelSocial infrastructure: e.g. obligations for persistence, back-up,
in event of failure, etc.
Standardisation (ISO 26324 etc), liaisons, etc.
Outreach to new communities“Not for profit” membership federation
Registration Agencies are biggest part of membershipElected Board, working groups, meetings

4Registration Agencies (RAs)
•••••
••
•

Independent of each other
Each have own business model with their customers
Have a licence/operating agreement for DOI
Share costs of common infrastructure (IDF)
Implement standard DOI system
Can add their own services on top, and run their own
databases
Can be commercial, or not for profit
Many are member communities (e.g. CrossRef, EIDR,DataCite)

DOI system application areas•••••••Featured today: Scholarly information, science data
But also much wider e.g.
Film and TV (EIDR)
Construction products - prototyping with members
Digital rights management/copyright - RDI project ,Copyright Hub
Documentation in government, national collections.
Registration agencies can be in any area7

Technical infrastructure• Handle system: persistent identification in digital networks• Data model: principles for interoperability of data in e-commerce systems• We are working with others for long term continuity:• The Handle System: now under DONA Foundation– Resolution of identifiers on the internet– www.handle.net
www.DONA.net– DONA: Swiss Foundation for multi-primary Handle management, with EPIC, ITU,
China Handle Corp, CNRI, DONA
– Users of same resolution technology in several areas• Data model: Linked Content Coalition– Semantics of identifiers on the internet– www.LinkedContentCoalition.org;
www.rdi-project.org– Continuation of EU project: now a separate entity– Users of same data model in several areas

Social infrastructure
Shared development – e.g. APIs, datatypes, etc
Shared tools e.g. running mirror servers
Obligations for persistence:•••––To customers (within the RA)
In event of failure, etc.(beyond the RA)

Collaboration with other RAs
Enable shared DOI services where practical••–A customer could use more than one DOI service

Translation of information to local needs e.g.

•–––Chinese: www.doi.org/doi_handbook/translations/chinese/hb.html
Korean: www.doi.org/doi_handbook/translations/korean/hb.html
Japanese: under construction (JaLC)
