"A diagram is made up of symbols and is about concepts. It is abstract and propositional: its elements and spatial relations can be expressed as a set of statements."
The abstractness of a diagram is part of what makes it important. The imprecise quality helps the architect keep in mind "its abstract intention."
This paper sketches out how the electronic cocktail napkin program should be constrained with a list of constraints.
