Element Description

The Granule UR element provides the universal reference id of the granule, which is assigned by the data provider. As a result, the id will vary based on data provider.

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.


  • Manual Review
    • Check that the quality description is appropriate for the data set.
    • Identify errors, discrepancies or omissions.
    • Proof all content for conciseness and readability.
  • Automated Review
    • Check for potential broken links.
    • Check that the field length is not greater than 12,000 characters.

ARC Priority Matrix

Priority CategorizationJustification

This element is categorized as highest priority when:

  • The Quality description contains a spelling or grammatical error.
  • The element is being used incorrectly (i.e. for a purpose other than describing data quality).
  • A broken URL is provided in the Quality element.

This element is categorized as medium priority when:

  • A recommendation is made to change the syntax or content provided the Quality element to improve readability.

This element is categorized as low priority when:

  • A URL provided in the Quality element is a re-direct link (this includes re-directs 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."
