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)

Element Specification

Providing a Data Language is optional. Multiple Data Languages may be provided, if necessary (Cardinality: 0..*)

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).

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The data languageData Language(s) provided are incorrect for the dataset.
Yellow = Medium Priority Finding	Not applicable
Blue = Low Priority Finding	This element is categorized as low priority when: No data language Data Language is provided when the data language Data Language is a language other than English (the assumed default language).
Green = No Findings/Issues	The element is provided and follows all applicable criteria specified in the best practices section above.
