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"

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).

Please see the expandable sections below for flowchart details.


  • 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.
  • This element is required
  • Must contain at least 1 character and be no longer than 80 characters in length
  • The ShortName together with the Version must be unique per data provider

ARC Priority Matrix

Priority CategorizationJustification

Red = High Priority Finding

This element is categorized as highest priority when:

  • 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

The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Checks

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