A Protégé-1 form for entry of classes of task-level actions. Here, the user is entering into a domain-independent form the kinds of actions that a planner should take in the setting of different situations involving the input data provided to the runtime system. The actions correspond to the entries in the menu displayed by the OPAL program in Figure 3. Protégé-1 had dozens of such forms with which a user could specify the domain model for a customizable knowledge-acquisition tool that had much of the functionality of OPAL.
