When you begin to create instances for a class, you may see that the names used in the Instance Browser are not very useful. You can change the display so that the instances are listed by the values of one (or more) fields; for example, a "Name" field or a "Headline" field. To do this, you set the display slot.

The display slot can be set in two locations: the Instance Browser and the Form Editor. You can also choose multiple slots for the display slot. If you do not set the display slot, Protege-Frames uses a default internal slot. If you set a display slot for a class, it is inherited by its subclasses.

Setting the Display Slot at the Instance Browser

To set the display slot at the Instance Browser:

1. At the Instances tab, click on the class for which you want to set the display slot.

2. Click the Instance menu icon at the top right of the Instance Browser.

3. Select Set Display Slot from the menu.
