AWS::IoTSiteWise::AssetModel Transform

Contains an asset transform property. A transform is a one-to-one mapping of a property's data points from one form to another. For example, you can use a transform to convert a Celsius data stream to Fahrenheit by applying the transformation expression to each data point of the Celsius stream. Transforms can only input properties that are INTEGER, DOUBLE, or BOOLEAN type. Booleans convert to 0 (FALSE) and 1 (TRUE)..
