Element Description

The Version element indicates the version of the dataset.

Best Practices

The version should be consistent throughout the metadata record. The version in the metadata should be identical to the version specified on the dataset landing page and in dataset documentation. For example, if the dataset landing page specifies the dataset as version 1.1, then the version number in the metadata should also be 1.1 (e.g. not 1.10). If the version in the title is specified as 3.4.2004 then the version in the metadata should also be 3.4.2004 (e.g. not 03.04.2004).

Examples:

"2.0"

"1"

"007"

Element Specification

Model	Element	Type	Constraints	Required?	Cardinality
UMM-C	Version	String	1 - 80 characters	Yes	1

Note: The short name and version combination must be unique across the CMR.

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).

Manual Review
- Check that the version value is appropriate for the dataset.
Automated Review
- Check that the field has been populated.
- Check that the field length is not greater than 80 characters.

ARC Priority Matrix

Not applicable

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The element is not included at all. The element is included but is empty. The version is incorrect for the associated data. No Version is provided. The Version is incorrect for the dataset.
Yellow = Medium Priority Finding	Not Applicable
Blue = Low Priority Finding	Not Applicable
Green = No Findings/Issues	Not applicable	The element is provided , and follows all applicable criteria specified in the best practices section above.

ARC Automated Checks

Checks to see if a Version ID is provided; if not, return is: "Recommend providing a Version ID for this dataset, as this is a required field."

Otherwise, return is "OK"

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