Once a slot has been created, you can attach it to one or more classes. For example, the name slot appears both at Organization and Person.
To choose a pre-existing slot to add to your class:
Make sure the correct class is highlighted in the Class Relationship pane.
Click the Add
button at the top right of the pane. The Select Slots form displays all the
slots you can add to the class.
Highlight the slot you wish to add to your class.
Click OK.
The new slot is added to the Template Slots pane. It is a directly attached slot and is displayed with a blue
icon. You do not need to name the slot or define its facets. However, if you
wish to edit override the slot, you may double-click it or click the top-level View
or the class-level View
button to display the Slot Form. See Viewing a Slot
and Editing Slot Properties for more information.
