Element Description
Note: This page is a draft/ work in progress
The Paleo Temporal Coverage element defines the time period in which geologic and/or paeloclimate paleoclimate data collection occurred. The element is predominantly used for data collection that occurred prior to 01-01-0001. As a result, it is not an element that is commonly used.
Best Practices
Paleo Temporal Coverage keywords tags identify areas time periods where geologic and paleoclimate data collection occurred. The keywords time period tags can be chosen to classify broad study areas/regions or very specific placessimply 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 location keywords Paleo Temporal Coverage tags are as specific as possible to aid in data discovery. At bare minimum, a location keyword/category is required in the hierarchy, which provides a general area of data collection. It is also recommended that this If a specific location keyword 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.

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).
