The organization of DOI registration
11
International DOI Foundation (IDF): oversees the
central DOI system, promotes the DOI as a
standard, and provides an organizational
infrastructure that ensures persistence and
interoperability.
Corporation for National Research Initiatives
(CNRI): they (among other things) are responsible
for the Handle system, which is the technology that
causes DOIs to resolve to the registered URL
Registration Agencies (RAs): Register DOIs on
behalf of other organizations. CrossRef is a RA.
Registration Agencies
• Airiti
• CrossRef
• China National
Knowledge
Infrastructure (CNKI)
• DataCite
• Entertainment Identifier
Registry (EIDR)
• The Institute of
Scientific and Technical
Information of China
(ISTIC)
• Japan Link Center
(JaLC)
• Multilingual European
DOI Registration
Agency (mEDRA)
• Publications Office of
the European Union
(OP)
Different registration agencies provide different services
They all provide the basic DOI linkage service

Deposit DOIs and metadata
• Basic citation
metadata:
– author(s)
– journal title
– article title
– volume
– Issue
– page numbers
– publication date
– book title
– chapter title
• Optional metadata,
e.g.
– references
– funder information
– ORCIDs
– CrossMark publication
record metadata
– Abstracts
– (more about this later)

CrossRef Isn’t Just for Journals
14
Components are
parts of an article
(e.g. Figures, tables)
which are allocated
their own DOI
