DOIs in support of research
activities
What is this webinar about?
• Why do we need Permanent Unique Identifiers (PIDs)?
• What is a PID and what characteristics does it have?
• Different types of PIDs
• Digital Object Identifiers (DOIs)
• How does it work?
• Advanced services
• DOI application domains
Why do we need Permanent Unique Identifiers?
• Accurate identification of objects of interest
• Findability of information
• Accessibility of information
• Interoperability of information systems and processes
• Reusability of data
• Repeatability of experimental conditions
• Reliability of results

What is a Permanent Unique Identifier (PUID)?
“A text string that unambiguously and permanently identifies a single object of interest”text string
A sequence of characters valid according to some syntax rules
single object of interest
One identifier corresponds to one and only one object
permanently
Once established, the association between the identifier and the object is never broken
unambiguously
The identifier is all you need to get the associated object
Main characteristics of a PUID
• Unique
The association between object and identifier is never broken• Permanent
• Actionable ResolutionDiscovery
• Opaque Cannot infer any information on the object by just lookingat the identifier

Some facts about DOIs
• International DOI Foundation created in 1996 by the three major international publishing
trade associations
• ISO 26324 standard
• About 145 Million DOIs registered so far, with an annual growth rate of 16%
• IDF maintains the Global DOI System (network of redundant servers worldwide)
• DONA Foundation: joint initiative with other major players to ensure sustainability of the
infrastructure
• IDF operates through Registration Agencies
Structure of a DOI
10
Identifier of DOI within the Handle System
<prefix>
Registrant identifier assigned by the Registration Agency
<suffix>. /
Identifier guaranteed unique by the Registrant
• 10.3204/PHPPUBDB-25818• 10.18730/1W34E• 10.1109/5.771073
Examples of DOIs
What does a Registrant agree to?
• Maintain the association between the DOI and the object
• Maintain the “landing page”
Never use the same DOI for any other object

How do I get DOIs for my research?
• Define the use case
• Identify a DOI minting service that best suits your needs
• Become a member of the Registration Agency
• Understand the metadata structure
• Submit registration requests
• Comply with your obligations
What will my DOIs identify?
Check if your institution/organization already assigns DOIs
CrossRef focuses on publicationsDataCite for publications and other usesSeveral other RAs in specific countries and for specific sectors
Map your metadata to the ones required to get a DOI
Usually via a XML documentDataCite will soon offer a web formNever use the same DOI for another objectMaintain the landing page
