Element Description

The temporal keyword element specifies a word or phrase which serves to summarize the temporal characteristics of a dataset.

Best Practices

Temporal Keywords is an optional element. There is not a controlled vocabulary for temporal keywords. If this element is utilized it is recommended that a consistent naming convention be developed for related records or for records from the same data center.

Examples:

TemporalKeywords: "Weekly"

TemporalKeywords: "Subannual"

TemporalKeywords: "Annual Climatology"

Element Specification

Providing the Temporal Keyword element is optional. Multiple Temporal Keywords may be provided (Cardinality: 0..*).

Model	Element	Type	Constraints	Required?	Cardinality
UMM-C	TemporalKeywords	String	1 - 80 Characters	No	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).

title	GCMD Metadata QA/QC

Manual Review
- Identify errors, discrepancies or omissions.
- Verify that all pertinent keywords have been applied.
- Verify that existing facets and other controlled keyword values are consistent and suitable for the data.
Automated Review
- Check that the field has been populated.
- Check that the field is populated with a valid value from KMS.
- Check that the field value is not a duplicate.
- Check that the 'Detailed_Variable' field length is not greater than 80 characters.

ARC Priority Matrix

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The Temporal Keyword is not appropriate for the dataset.
Yellow = Medium Priority Finding	This element is categorized as medium priority when: A recommendation is made to change a Temporal Keyword to be more accurate or more consistent with related collections.
Blue = Low Priority Finding	This element is categorized as low priority when: The element is included but is empty (i.e. empty temporal keywords tags are provided in the metadata record). A recommendation is made to add a relevant Temporal Keyword to the metadata.
Green = No Findings/Issues	The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Checks

If no value isprovided, return is "np"If a value is provided, return is "OK"

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