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).

[]

Please see the expandable sections below for flowchart details.

GCMD Metadata QA/QC

Manual Review
- Verify that the DOI resolves to the appropriate web page
Automated Review
- Check that the field length is not greater than 1,024 characters
- Check that the DOI is resolvable
- Check that the DOI syntax is valid

ARC Metadata QA/QC

ARC Priority Matrix

Priority Categorization	Justification
	This element is categorized as highest priority when: The element is not included at all. The element is included but is empty. The dataset has a DOI but the metadata indicates that it does not. The incorrect DOI is listed for the dataset. The DOI listed leads to a broken link. The DOI is provided in the incorrect format (e.g. as a URL rather than just the DOI string). The DOI/Explanation includes spelling or grammatical errors.
	This element is categorized as medium priority when: The DOI/MissingReason option is used but no DOI/Explanation is provided.
	This element is categorized as low priority when: A DOI is provided but the DOI/Authority element is not provided.
	The element is provided, and follows all applicable criteria specified in the best practices section above.

ARC Automated Rules

Checks if a value is provided, if not, return is: "DOI is a required metadata element for NASA data sets. Please provide a DOI for the data set, if applicable. "
If a value is provided, return is "OK"
