Sam, Could the following be another example?
The Blood pressure. The RR as an act, a measurement, a procedure. And the RR as a set of values, the result of the act, the measurement results, the result of a procedure. The act is one thing, an intention. The value as the result of the execution of the intention. The intention can exist without a real value. In ENV 13606 part 2 there are the possibilities to add modifiers (attributes) to 'things' that can express concepts like these. The question is: Will we need a new Concept Information Model (archetype) to distinguish between the two or is one attribute enough?
