DOI: THE persistent identifier

• DOI is the only widely adopted persistent, actionable identifier for

online scholarly works

– There is also a growing consensus that identifiers should be actionable. An

actionable identifier provides a means for a user to use the identifier discover

information about the resource. HTTP URIs are the form of actionable

identifiers preferred by the Linked Data community.

• A DOI persists throughout changes in copyright ownership or

location because it’s just a name used to look up an address in

an easily updateable directory

• The core functionality of the DOI system is to resolve the DOI to

the registered, updateable URL

What Does CrossRef Do?

• Provides technology infrastructure for linkingNo broken links in citations or database records

because it uses the DOI

•Provides business infrastructure for linkingOne agreement with CrossRef is a linking agreement

with all CrossRef publishers

Why search for a CrossRef

DOI?

• To help navigation

– To look up CrossRef DOIs for your citations so

you can include them in bibliographies, article

references, blog posts, or wherever you need.

– Linking via the CrossRef DOI means it will point

to the authoritative version of the work

maintained by the publisher, which will update if

the content moves.
