+## Feature Flag Attributes
+<!-- semconv registry.feature_flag(omit_requirement_level) -->
+| Attribute  | Type | Description  | Examples  |
+|---|---|---|---|
+| `feature_flag.key` | string | The unique identifier of the feature flag. | `logo-color` |
+| `feature_flag.provider_name` | string | The name of the service provider that performs the flag evaluation. | `Flag Manager` |
+| `feature_flag.variant` | string | SHOULD be a semantic identifier for a value. If one is unavailable, a stringified version of the value can be used. [1] | `red`; `true`; `on` |
+
+**[1]:** A semantic identifier, commonly referred to as a variant, provides a means
+for referring to a value without including the value itself. This can
+provide additional context for understanding the meaning behind a value.
+For example, the variant `red` maybe be used for the value `#c05543`.
+
+A stringified version of the value can be used in situations where a
+semantic identifier is unavailable. String representation of the value
+should be determined by the implementer.
