Introduction

In DvSum, the Usability Score measures the completeness of a table’s metadata. A full score of 10 indicates that all essential metadata fields have been properly filled in, promoting better governance, discoverability, and trust in the data asset.

Note:

• Full Score = 10: Achieved when all required metadata fields are populated.
• Partial Score: If some fields are missing, the score is calculated as the average of the available metadata inputs.

  • If the Usability score is not 10/10 then the asset will considered as Incomplete.

Required Metadata Fields for Full Score

To reach a usability score of 10/10, the following fields must be filled in:

• Description
• Ownership
• Tags
• Domains
• Additional Info
• Lineage
• Additional info.

Note: Missing even one of these fields will reduce the score.

Making the term Complete

The “Incomplete” filter tab automatically displays terms that are missing one or more of the required properties needed for completeness.

A term will move out of the Incomplete status once the following three required fields are updated and published:

• Description
• Ownership
• Data Domain

Note: If any of these fields remain empty, the term will continue to show as Incomplete. Additionally, if the domain has workflow enabled, approval from the designated approver will still be required as per the existing process.
