Hello, I wanted to add a property called avgSpeed to an instance of a class called FlowSensor. This property should be the average of the values of the property vehicleSpeed attached to instances of the class Vehicle.
I read that SPARQL update allows doing this. However, I cannot reach the syntax for doing the* averaging of values* or for building the *SPARQL Update *query using jena with eclipse on the jena website. If Jena indeed supports doing what I intend to do then can someone point out some sources to guide me in my attempt? Best Regards, Aya
