Element Description

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

Best Practices

Examples:

TemporalKeywords: "Weekly"

TemporalKeywords: "Subannual"

TemporalKeywords: "Annual Climatology" 

Element Specification

Providing the Temporal Keyword element is optional (Cardinality: 0..*)

ModelElementTypeConstraintsRequired?Cardinality
UMM-CTemporalKeywordsString1 - 80 CharactersNo0..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).

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

This element is categorized as highest priority when:

  • The Temporal keyword is not appropriate for the dataset.

This element is categorized as medium priority when:

  • A recommendation is made to add a relevant Temporal keyword to the metadata.

This element is categorized as low priority when:

  • The element is included but is empty.
  • The Temporal keyword is not appropriate for the dataset.

The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Checks

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

KMS controlled. This is where the entire keyword hierarchy should be listed. Each keyword in the hierarchy must be separated by "&gt;". If any keyword is missing and there exists a keyword later in the hierarchy, use NONE to fill in the values in between. The CMR will not translate the NONE values they are only used to place each keyword in its correct space in the hierarchy.
