 ** attribute **   <a name="iotsitewise-Type-PropertyType-attribute"></a>
Specifies an asset attribute property. An attribute generally contains static information, such as the serial number of an [IIoT](https://en.wikipedia.org/wiki/Internet_of_things#Industrial_applications) wind turbine.  
Type: [Attribute](API_Attribute.md) object  
Required: No

 ** measurement **   <a name="iotsitewise-Type-PropertyType-measurement"></a>
Specifies an asset measurement property. A measurement represents a device's raw sensor data stream, such as timestamped temperature values or timestamped power values.  
Type: [Measurement](API_Measurement.md) object  
Required: No

 ** metric **   <a name="iotsitewise-Type-PropertyType-metric"></a>
Specifies an asset metric property. A metric contains a mathematical expression that uses aggregate functions to process all input data points over a time interval and output a single data point, such as to calculate the average hourly temperature.  
Type: [Metric](API_Metric.md) object  
Required: No

 ** transform **   <a name="iotsitewise-Type-PropertyType-transform"></a>
Specifies an asset transform property. A transform contains a mathematical expression that maps a property's data points from one form to another, such as a unit conversion from Celsius to Fahrenheit.  
Type: [Transform](API_Transform.md) object  
Required: No
