Element Description
This element stores the DOIs (Digital Object Identifier) for associated collections. A DOI is a persistent identifier that is used to uniquely identify objects including datasets and documents. This element allows data providers to associate parent collections, or other peer collections together. These DOIs are searchable through Earthdata Search and the CMR API. Use the "doi" parameter to search for collection DOIs or the associated DOIs.
This element also includes the option to provide information on the authority that registers the DOI as well as the title to allow users to quickly understand the relationships.
Best Practices
The Associated DOIs main element is defined as a list of Associated DOIs, which means that 1 or more associations with other collections or other items can be made. There are multiple sub-elements that comprise Associated DOIs:
DOI: The DOI (Digital Object Identifier) that identifies the associated collection.
- When providing information in the 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:
- 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".
Title: The title or very short description of the item the DOI describes.
Authority: The DOI organization that is responsible for creating the DOI.
- For ESDIS providers specifically:
- The CollectionDOI/Authority element value should be "https://doi.org/"
Examples:
DOI: "10.5067/ISS/CATS/L2O_N-M7.1-V2-01_05KMPRO"
Title: " CATS-ISS Level 2 Operational Night Mode 7.1 Version 2-01 5 km Profile"
Authority: "https://doi.org/"

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).
