Paleo Temporal Coverage

Element Description

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.

Best Practices

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.

Examples:

PaleoTemporalCoverage/StartDate: "560 ka"

PaleoTemporalCoverage/EndDate: "60 ka"

PaleoTemporalCoverage/ChronostratigraphicUnit/Eon: "PHANEROZOIC"

PaleoTemporalCoverage/ChronostratigraphicUnit/Era: "CENOZOIC"

PaleoTemporalCoverage/ChronostratigraphicUnit/Period: "QUATERNARY"

PaleoTemporalCoverage/ChronostratigraphicUnit/Epoch: "PLEISTOCENE"

PaleoTemporalCoverage/ChronostratigraphicUnit/Stage: "LATE"

PaleoTemporalCoverage/StartDate: "175 myr"

PaleoTemporalCoverage/EndDate: "160 myr"

PaleoTemporalCoverage/ChronostratigraphicUnit/Eon: "PHANEROZOIC"

PaleoTemporalCoverage/ChronostratigraphicUnit/Era: "MESOZOIC"

PaleoTemporalCoverage/ChronostratigraphicUnit/Period: "JURASSIC"

PaleoTemporalCoverage/StartDate: "100 ka"

PaleoTemporalCoverage/EndDate: "20 ka"

PaleoTemporalCoverage/ChronostratigraphicUnit/Eon: "PHANEROZOIC"

Element Specification

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/StartDate	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/EndDate	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	GCMD Chronostratigraphic Unit Eon Keywords	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.

ARC Priority Matrix

Priority Categorization	Justification
	This element is categorized as highest priority when: The element is not included at all (for relevant collections). The element is provided but it is not applicable for the dataset (i.e. data were collected after 0001-01-01) 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).
	The element is categorized as low priority when: 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).
	The element is provided and follows all applicable criteria specified in the best practices section above.
