Element Description

The DOI element stores the DOI (Digital Object Identifier) that identifies the collection. The DOI organization that is responsible for creating the DOI is described in the Authority element. The DOI/MissingReason element can be used for datasets that do not have a DOI or which use a different type of persistent identifier. 


Best Practices

Just the DOI string should be provided in the DOI field. The DOI URL should not be stored here; it should be stored as a RelatedURL. The DOI value should start with the directory indicator.

For ESDIS providers:

  • The directory indicator for ESDIS is "10"   
  • If the DOI was registered through ESDIS, the beginning of the DOI string should be "10.5067"
  • The DOI/Authority element value should be "https://doi.org/"
  • A list of DOIs registered through ESDIS can be found here: EOSDIS DOIs Status and Listing
  • DOI is a required metadata element for ESDIS providers. While the majority of ESDIS datasets will have a DOI, there are certain cases where having a DOI is not appropriate. These cases include near real time datasets and datasets that will soon be replaced by a new version. In the case that a DOI is not applicable for a dataset, the DOI/MissingReason element should be used to indicate this and the DOI/Explanation element should be used to describe why the dataset was not assigned a DOI.   

DOI Examples:

"10.5067/ISS/CATS/L2O_N-M7.1-V2-01_05KMPRO"

"10.5067/MEASURES/GWELD/GWELDYR.003"

"10.5067/3UGE8WQXZAOK"

Missing DOI Examples:

"The collection is near real time and only exists for a couple of days, therefore, the collection was not assigned a DOI."

"A new version of this dataset will be released in a month (May 2018). This version will be removed from CMR and the new version will be assigned a DOI."
