Element Description

The Metadata Language element specifies the language used in the metadata record.

Best Practices

While not required, it is recommended that an ISO 639-2 code be used to populate the Metadata 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 Metadata Language is optional. Only 1 Metadata Language may be provided (Cardinality: 0..1)

Model	Element	Type	Constraints	Required?	Cardinality
UMM-C	MetadataLanguage	String	1 - 25 characters	No	0..1

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).

ARC Priority Matrix

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The metadata language Metadata Language provided does not reflect the language used in the metadata.
Yellow = Medium Priority Finding	Not applicable
Blue = Low Priority Finding	This element is categorized as low priority when: No metadata language Metadata Language is provided when the metadata 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.

ARC Automated Checks

ARC uses the pyQuARC library for automated metadata checks. Please see the pyQuARC GitHub for more information.
