What's the proper way to indicate that a one-to-many should be a Map?

asked May 5, 2020 in Question / help by matthewadams12 (240 points)

Let's say I have a Thing, and it has zero or more Widgets, but I want to indicate that the collection of Widgets is supposed to be a Map<String,Widget>? This is the best I've come up with (somehow tack on some constraint text):

Thing "1" *-- "0..*" Widget : widgets { Map<String,Widget> }

Is there a better way?
