The case for Digital Objects Identifiers (DOIs) in support of research activities

313 views

Published on

Research activities rely on access and repeatability of results. Accurate identification of the subject of the research as well as of the techniques and methods used is critical to obtain reliable results.
The adoption of Permanent Unique Identifiers, and specifically Digital Object Identifiers (DOIs)promotes access and reusability of data in modern research. The webinar begins with some basic concepts on Permanent Unique Identifiers. Next, DOIs are introduced describing how they are managed, how they can be obtained and how their features can be of benefit to researchers in a wide range of fields.

The case for Digital Objects Identifiers (DOIs) in support of research activities

  1. 1. FAO AIMS Webinar 28/06/2017 Marco Marsella DataCite Executive Board DOIs in support of research activities
  2. 2. 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
  3. 3. 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 FAIR
  4. 4. 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
  5. 5. Main characteristics of a PUID • Unique The association between object and identifier is never broken• Permanent • Actionable Resolution Discovery • Opaque Cannot infer any information on the object by just looking at the identifier Yugoslavia/1987/Acacia 31AW56 One identifier one object
  6. 6. Different flavors of PUID •PURL Persistent Uniform Resource Locator http://purl.obspm.fr/vocab/Algorithms/GaussSeidel •UUID Universally Unique Identifier urn:uuid:7d8e6379-0636-416c-b3bc-ee4680e7c3f1 •LSID Life Science Identifier urn:lsid:ncbi.nlm.nig.gov:GenBank:T48601:2 •ARK Archival Resource Key http://texashistory.unt.edu/ark:/67531/metapth346793/ •DOI Digital Object Identifier http://doi.org/10.5438/0012
  7. 7. 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
  8. 8. 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
  9. 9. 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 10.5438/0013
  10. 10. 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 publications DataCite for publications and other uses Several other RAs in specific countries and for specific sectors Map your metadata to the ones required to get a DOI Usually via a XML document DataCite will soon offer a web form Never use the same DOI for another object Maintain the landing page
  11. 11. Advanced services available through DOIs • EventData • Organization identifiers • Citation formatter • Link checker • Data quality assessment • Impact assessment
  12. 12. DOI application domains • Publications • Datasets • Database queries • Software • Technical instrumentation • Instrumentation settings • Arts and other Human sciences
