# AssetPropertyValue


A structure that contains value information. For more information, see [AssetPropertyValue](https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_AssetPropertyValue.html) in the * AWS IoT SiteWise API Reference*.

You must use expressions for all parameters in `AssetPropertyValue`. The expressions accept literals, operators, functions, references, and substitution templates.

**Examples**
+ For literal values, the expressions must contain single quotes. For example, the value for the `quality` parameter can be `'GOOD'`.
+ For references, you must specify either variables or input values. For example, the value for the `quality` parameter can be `$input.TemperatureInput.sensorData.quality`.

For more information, see [Expressions](https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-expressions.html) in the * AWS IoT Events Developer Guide*.
