# EnumerationMissingName validation rule

> Validates that each enumeration value in the data model has a human-readable name. Improves usability, maintainability, and AI-readiness.

This rule checks that every enumeration value in the data model has a human-readable name.

## Why it matters

A missing name makes it harder for users (humans or machines) to understand the purpose of the enumeration value.
This is important as enumeration values are often technical codes or abbreviations, and a clear name improves
usability, maintainability, searchability, and AI-readiness.

## Example

An enumeration value with ID `NOM` in a wind turbine operational mode property has no name. Users may find it
difficult to understand what the value represents. Adding a name such as "Normal Operation" improves clarity
and usability.
