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. For ESDIS records the value of http://dx.doi.org should be used. While this element is not required, NASA metadata providers are strongly encouraged to include DOI and DOI Authority for their collections.
Choice of:
DOI/DOI: The DOI element stores the DOI (Digital Object Identifier) that identifies the collection.
DOI/Authority: The DOI organization that is responsible for creating the DOI is described in the Authority element.
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.
Best Practices
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.
- Provide example here
- 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. 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. 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: EOSDIS 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/"
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/"
or
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."
