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
- Check that the purpose description is appropriate for the data set
- Automated Review
- Check that the field has been populated
- Check that the field length is not greater than 1000 characters

ARC Priority Matrix
Priority Categorization | Justification |
---|
| This element is categorized as highest priority when: - The purpose contains spelling or grammatical errors
- The purpose is incorrect for the data (for example, a copy + paste error could result in the purpose for a different data set to appear in this field)
- A broken URL is provided in the purpose element
|
| This element is categorized as medium priority when: - The information provided in the purpose element is better suited for a different metadata field (i.e. incorrect usage of the purpose field)
|
| This element is categorized as low priority when: - A link provided in the purpose element needs to be updated from 'http' to 'https'
|
| The element is provided, and follows all applicable criteria specified in the best practices section above. |
ARC Automated Rules
- If no value is provided, return is "np"
- Otherwise, return is "OK"
