Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.

reported by a measurement result
Authored explanation
A measurement result reports a value attributed to a specified physical quantity together with the measurement model, conditions, unit convention, and any required qualification.
How to interpret this relation type
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
