For each feature class, you can define a representation string that will be displayed in the feature explorer. You can display any feature class attribute, or the topic. Also you can display units. By default, the feature explorer displays the FID of the features.
For example, when displaying the results of a road network tracing in the feature explorer, you can specify that the road name is displayed instead of the FID. You define the representation string in the data model administrator.
As another example, when displaying the results of a utility network tracing in the feature explorer, you can specify that both the attribute feature class and the related geometry feature class is displayed.
The representation string is stored in the system table IM_DICTIONARY.
