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.

String

This element maps to the UMM-G Element Grid Mapping Names.

Note that this element is included with the spatial extent block , therefore; a new 'geographicElement' needs to be added for each grid mapping name. The geographicElement includes the boundingBox id.
