Best Practices

Paleo Temporal Coverage tags identify time periods where geologic and paleoclimate data collection occurred. The time period tags can be chosen to simply classify the start and end dates for data collection or they can more specifically identify the era, eon and stage, just to name a few tags, for the data collection time period. However, it is suggested that Paleo Temporal Coverage tags are as specific as possible to aid in data discovery. Because the tags are KMS controlled, if a specific tag is not already included in the KMS, a request to have it added can be made through the GCMD Keywords Community Forum.

Examples:

PaleoTemporalCoverage/PaleoStartDate: "560 ka"

PaleoTemporalCoverage/PaleoEndDate: "60 ka"

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.

ARC Priority Matrix

This element is categorized as highest priority when:

• The element is not included at all (for relevant collections).
• The element is included but is empty.
• The paleo temporal coverage term does not align with the KMS.
  • The paleo temporal coverage term does not exist in KMS.
  • A term(s) is missing from the hierarchy.
  • A term(s) is placed in the incorrect position of the hierarchy (e.g. an Eon term is placed in the Epoch field).
• The paleo temporal coverage term is not appropriate for the dataset.

This element is categorized as medium priority when:

• A recommendation is made to add a relevant paleo temporal coverage term to the metadata.
• A recommendation is made to add to an existing term in the metadata (i.e. to extend a keyword hierarchy down to a more detailed keyword).
