You can use the map operator with temporal attributes just as if you would use non-temporal attributes only. You can mix temporal and non-temporal attributes. Just be careful with the Limitations with direct temporal functions. If you have a temporal attribute involved, the result of the expression will typially be a temporal attribute. Internally, a TemporalRelationalMapPO is created with a TemporalRelationalExpression.

/// Energy consumption per household per minute in the next 15 minutes
derivative = MAP({
	expressions = [
		['derivative(temp_wh, PredictionTimes)','whPerMinute'],
		['id','id']
	]           
},predTime)
              
/// Energy consumption per household per minute in the next 15 minutes
watts = MAP({
	expressions = [
		['whPerMinute * 60','watt'],
		['id','id']
	]           
},derivative)
