Since values are entities and not literals in GoodRelations, it is easily possible to provide contextual information in the form of value references, e.g for indicating the temperature of a pressure (1 atm at 20 degrees Celsius), the voltage for a particular energy consumption (2 kwh at 220 volts), or the rotational speed for a certain torque (1 Nm at 5400 rpm).
