Element Description

The language used in the metadata record.

Best Practices

It is recommended that the value for this element be selected from a list of language codes. 

If not supplied the default language of English will be assumed.

The ISO standard for language codes that we will use is ISO 639-2.  For more information please see the ISO 639-2 language code web site at http://www.loc.gov/standards/iso639-2/php/code_list.php.

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).

Please see the expandable sections below for flowchart details.
