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).

ARC Priority Matrix

This element is categorized as low priority when:

N/A

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The Collection Data Type is not a valid value: SCIENCE_QUALITY, NEAR_REAL_TIME, OTHER The Collection Data Type provided is incorrect	This element is categorized as medium priority when: N/A	.
Yellow = Medium Priority Finding	Not Applicable
Blue = Low Priority Finding	Not Applicable
Green = No Findings/Issues	The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Rules

If novalue is provided, return is "np"

Checks

ARC uses the pyQuARC library for automated metadata checks. Please see the pyQuARC GitHub for more information.

Otherwise, return is "OK"
