Element Description

Note: This wiki page is a draft/ work in progress

The Collection Data Type element  is used to identify the collection as a Science Quality Collection or as a non-science-quality collection such as a Near Real Time collection.

Best Practices

 If a collection does not contain this field, it will be assumed to be of science-quality.

SCIENCE_QUALITY: All EOS and non-EOS data and data products that are archived.

NEAR_REAL_TIME: Data from the source that are available for use within a time that is short in comparison to important time scales in the phenomena being studied. This data is not science quality and is not retained by EOSDIS once the SCIENCE_QUALITY product is archived.

OTHER: Any EOS and non-EOS data and data products, that are not SCIENCE_QUALITY and do not fall under NEAR_REAL_TIME holdings.

Examples:

CollectionDataType: Near_Real_Time

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).
