How to Label a Link
Labels are helpful to document the purpose of a functoid or a link in a map. You can use the Label property to name a link. This is useful when your map contains big schema structures and identifying the inputs and output links to a functoid becomes difficult.
Note
For information on how to label and comment functoids, see How to Label and Comment a Functoid.
