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).
