Best Practices
The version description should be brief and provide meaningful information about the version (i.e. beyond the version number itself). This could include what separates the current version of the dataset from the previous version. If it is the first version of a dataset, then the description can convey this. It may also include the date that the version of the dataset was released. It is also recommended that the version description provides information explaining if there are multiple versions of a dataset available at the same time or if there is a more recent version of the dataset available. This way, users can determine whether they are accessing the most appropriate version of the dataset for their applications.
Examples:
"This version 007 has been reprocessed. The algorithm has been updated to produce better science quality."

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).
