Element Description
This element stores the DOI (Digital Object Identifier) that identifies the data collection. A DOI is a persistent identifier that is used to uniquely identify objects including datasets and documents.
This element also includes the option to provide information on the authority that registers the DOI.
Best Practices
For the DOI concept, there are two options for providing information. These options are:
DOI/DOI: The DOI (Digital Object Identifier) that identifies the collection.
DOI/Authority: The DOI organization that is responsible for creating the DOI
or
DOI/MissingReason: This element stores the fact that a DOI is not applicable for a record.
DOI/Explanation: This element describes the reason the DOI is not applicable.
For DOI/DOI and DOI/Authority
DOI/DOI:
- When providing information in the DOI/DOI field, only the DOI string should be provided. The string value should begin with the directory indicator.
- The DOI URL should not be stored in the DOI element but should instead be provided as a RelatedURL.
- For ESDIS providers specifically:
- 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. Please see the DOI/MissingReason and DOI/Explanation section for more information.
- More details on the ESDIS DOI process can be found here: ESDIS DOI Process
- A list of DOIs registered through ESDIS can be found here: ESDIS DOIs Status and Listing
- The directory indicator for ESDIS is "10." Therefore, if the DOI was registered through ESDIS, the beginning of the DOI string should be "10.5067".
DOI/Authority:
- For ESDIS providers specifically:
- The DOI/Authority element value should be "https://doi.org/"
- For ESDIS providers specifically:
Examples:
DOI/DOI: "10.5067/ISS/CATS/L2O_N-M7.1-V2-01_05KMPRO"
DOI/Authority: "https://doi.org/"
DOI/DOI: "10.5067/MEASURES/GWELD/GWELDYR.003"
DOI/Authority: "https://doi.org/"
For DOI/MissingReason and DOI/Explanation
DOI/MissingReason:
- This element should only be used for specific cases where assigning a DOI to a dataset is not appropriate. These cases include near real time datasets, provisional datasets, and datasets that will soon be replaced by a new version.
- This element is controlled by the enumeration value "Not Applicable." For translation purposes, a value of "Unknown" is provided for data sets that do not have a DOI or a MissingReason set.
DOI/Explanation:
- This element should be used to describe why a dataset was not assigned a DOI.
Examples:
DOI/MissingReason: "Not Applicable"
DOI/Explanation: "The collection is near real time and only exists for a couple of days, therefore, the collection was not assigned a DOI."
DOI/MissingReason: "Not Applicable"
DOI/Explanation: "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."
AssociatedDOIs also exist so that data providers can add DOIs from either parent or other associated collections. This allows users to cite a group of data products.

Metadata Validation and QA/QC
All metadata entering the CMR goes through the below process to ensure metadata quality requirements are met. All records undergo CMR validation before entering the system. The process of QA/QC is slightly different for NASA and non-NASA data providers. Non-NASA providers include interagency and international data providers and are referred to as the International Directory Network (IDN).
