Element Description
The Purpose element contains suggested usage for the data and/or a description for why the resource exists. Any limitations on the resource (including, but not limited to, special restrictions, legal prerequisites, and terms and conditions) should be placed into the Use Constraints element and not into the Purpose element.
Best Practices
The Purpose element is optional. It can be leveraged to communicate to a user the broad applications the data is designed to be used for, and/or why the data were generated.
Examples:
"To assess species composition, abundance, distribution and biomass of zooplankton within the Bering and Chukchi Seas , 1985-1989."
"To provide VIIRS 375m resolution active fire locations in Near Real-Time in easy to use formats."
"To serve a wide user community by providing composite Landsat images and raw data for urban areas that can be used in interdisciplinary studies of remote sensing and the environment."

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).
