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).

titleGCMD Metadata QA/QC
  • 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.
