The Paleo Temporal Coverage element defines the time period for geologic and/or paleoclimate data. The element is predominantly used for data samples that originated prior to 01-01-0001.
Paleo Temporal Coverage tags identify time periods where geologic and paleoclimate data collection occurred. The time period tags can be used to identify the start and end dates for data collection. There is also the option to provide the names of the eon, era, period, epoch and stage associated with the data collection. It is suggested that Paleo Temporal Coverage tags are as specific as possible to aid in data discovery. The names of eons, eras, periods, epochs and stages must be selected from a controlled vocabulary list managed by the Keyword Management System (KMS). 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.
It is important to note that even if Paleo Temporal Coverage metadata is provided, it is still required that a Temporal Extent be provided in addition. Please see the Temporal Extent wiki page for details.
PaleoTemporalCoverage/StartDate: "560 ka"

Paleo Temporal Coverage is an optional metadata element, and should only be provided if it is applicable to the dataset. The Paleo Temporal Coverage element may not be repeated (Cardinality: 0..1).
|Model||Element||Type||Usable Valid Values||Constraints||Required?||Cardinality||Notes|
|UMM-C||PaleoTemporalCoverage/PaleoStartDate||String||n/a||1 - 80 characters||No||0..1||Provide a date unit for the start and end date (e.g. myr, ka, mya, B.C., etc.).|
|UMM-C||PaleoTemporalCoverage/PaleoEndDate||String||n/a||1 - 80 characters||No||0..1||Provide a date unit for the start and end date (e.g. myr, ka, mya, B.C., etc.)|
|UMM-C||PaleoTemporalCoverage/ChronostratigraphicUnits/Eon||String||KMS controlled||Yes, if applicable||1||Providing Chronostratigraphic Units are optional. If included, the Eon must be provided at a minimum.|
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.
- Identify errors, discrepancies or omissions.
- Proof all content for conciseness and readability.
