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, a title, an enumerated type element to allow users to quickly understand the relationships, and a DescriptionOfTypeOther when the type has a value of Other, so that curators can explain the relationship that is not in the type enumeration list.
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.
Title: The title or very short description of the item the DOI describes.
Authority: The DOI organization that is responsible for creating the DOI.
Type: The enumerated relationship between the record and the associated DOI. The enumerated values are: Child Dataset, Collaborative/Other Agency, Field Campaign, Parent Dataset, and Related Dataset, Other
Description Of Type Other: If the enumeration of Other is chosen for the Type element, the record curator needs to provide a short description that describes the relationship between the record and the associated DOI.
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/"
Type: Related Dataset

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.
