Ensuring your data can always be located

Digital Object Identifiers (DOIs)

When publishing your data, it’s good practice to apply a Digital Object Identifier (DOI) to your dataset. DOIs should be applied to your data when it’s:

  • in a finalised form - no further changes will be made
  • being made available via open or mediated access
  • going to be cited in a publication or as an output in its own right

Applying a DOI to your data means that the data will always have a persistent link to the original source, ensuring that your data can be cited and the impact of your data can be measured effectively. More information about data citation can be found under 'Find and use data'. To enquire about obtaining a DOI for your data, contact the Research Data team.



An ORCID is a persistent digital identifier that’s unique to you, meaning that if you use an ORCID all the articles and data that you’ve published or grants that you’ve submitted can be easily identified as yours. As ORCID easily groups all of your outputs, it can assist in getting a more accurate reading of citations and research impact. For more information, or to apply for an ORCID, visit the ORCID website.
