Element Description

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.

The Type must be selected from a controlled vocabulary list. There are three options available for Type

SCIENCE_QUALITY: Most data products that are permanently archived should be of science quality. Science quality means the data is in a state where it is trustworthy enough for use in scientific analyses (given known limitations of the data).

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. For EOSDIS, near real time data is not considered science quality and is not retained by EOSDIS once the SCIENCE_QUALITY product is archived.

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

Examples:

CollectionDataType: NEAR_REAL_TIME

CollectionDataType: SCIENCE_QUALITY

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).
