Introduction
Goal is to achieve generality and specificity at the same time. If client doesn't understand some operation it can lookup at operation hierarchy for more generic format and use that. It might lose some useful info but it doesn't usually lose all. For examples see article for CB#3.
op
Base operator for all operators. No parameters. Useful starting point for browsing operator hierarchy.
action
Derived from op.
Base operator for operations that might have effects.
create
Derived from action.
Create new things from nothing using this operator. Map editor is main user for this.
Parameters: entity describing object that is being created.
Example:
