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..*)

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.


  • 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 CategorizationJustification

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:

  • 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

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