DOI For Digital Assets


A Digital Object Identifier or DOI is a unique alphanumeric string that allows for a persistent link to the objects location on the Internet. The International DOI Foundation is the registry authority with numerous registration agencies that can mint (create) a DOI. Many publishers will assign a DOI to a journal article or a book and the DOI can be used as part of the citation in other publications or bibliographies. Citation formats can vary, and depended on the selected format of the journal or publisher. Check with the journal or publisher you are submitting as to how to correctly format a DOI citation. 

Citation Examples
APA format
Smith, A. B., & Doe, B. B. (Date of publication). Title of article. Title of Journal, volume number, page range. doi:0000000/000000000000 or

AMA/JAMA format
Smith AA, Doe BB. Title of article. Name of Jrnl. Year;vol(issue):inclusive pages. doi:10.0000000/000000000000

The University of Oklahoma Libraries (UL) uses CrossRef as its DOI registrar for use in ShareOK. Starting early in 2016, UL ran a pilot program for minting DOIs for selected research and observation digital assets (datasets) not hosted or maintained by UL. The research digital asset can be made up of any digital format that is part of the scholarly output from research. This can take the format of a traditional numerical dataset, a collection of photos or website, or even a scholarly blog. This pilot proved successful and now is providing to researchers the ability to have DOIs minted for their own hosted digital assets or small (5GB or less) hosted on ShareOK. Currently, a DOI portal request tool is being developed and in the meantime, DOI requests can be made through the by contacting your library specialist or the research data specialist. UL will cover the cost of the first five minted DOIs, after which the costs will need to be covered by the requesting researcher or department at a cost of $1.00/DOI. Updates and corrections for a DOI are made at no charge. 


  • DOIs enable accurate data citation
  • DOIs assist in the tracking of metrics and alt-metrics
  • DOIs allow for resolvable links to data which help with discovery, attribution, and reuse
