Element Description
The Data Language element describes the language used in the preparation, storage, and description of the collection. It is the language of the collection data itself. It does not refer to the language used in the metadata record (although this may be the same language). Please refer to the Metadata Language wiki page on how to specify the language used in the metadata.
Best Practices
While not required, it is recommended that an ISO 639-2 code be used to populate the Data Language field (http://www.loc.gov/standards/iso639-2/php/code_list.php). If a language is not supplied - English, the default language, will be assumed.
Examples:
"eng" ← Example using the ISO 639-2 code for English
"French" ← Example where the ISO 639-2 code is not used
"chi (B)" ← Example using the ISO 639-2 code for Chinese (See this FAQ for an explanation why "(B)" is included in the code)

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).
