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 options to provide information on the authority that registers the DOI, as well as the DOI of the previous version of the record.
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.
DOI/PreviousVersion: The previous version of this record's DOI, if applicable. Its sub elements are:
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.

DOI/MissingReason:
DOI/Explanation:
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.

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).
Please see the expandable sections below for flowchart details.
