The Standard Field Types
Template slots for a class are translated to entry fields for an instance of that class. For each slot in the class, the Instance Editor displays a field where a user can enter information corresponding to that slot. For example, the headline slot for the Article class becomes a field where the user can enter a headline for an instance. The display and options for the field depend on the type of information that can be entered in the field.
The different field types are based on the value type of the corresponding slot. For example, a slot of value type String is represented by a String entry field.
Note: These topics describe the default fields only. You can select different formats for some fields, using the Forms Tab.
