Template Slots
Slot name Documentation Type Allowed Values/Classes Cardinality Default
normal termination A state that holds when the script is "successfully completed." This might serve as the basis for reasoning about goals.

Instance  Empty_scoop  0:1   
start time The first time when an event is happening (holds). This might be an integer or a class.

Any  Temporal_measure  0:1   
follows When one interval starts after another ends.

Instance  Initial_sand-flicking  0:*   
precedes When one interval ends before another starts.

Instance  Process  0:1   
interruption An event that results in the script not reaching the goal state.

Instance  Event  0:1   
synchronous The idea is two complex or cyclic complex events that maintain phase as they proceed.

Instance  Process  0:*   
normal_termination A state that holds when the script is "successfully completed." This might serve as the basis for reasoning about goals.

Instance  State  0:1   
end time Like start_time, but the other end of the interval. Likewise start_time, not ready to commit to integer vs. class for the value here.

Any  Temporal_measure  0:1   
parts The elements that make up a script. Somehow it would be nice to fill these automatically with defaults when a script instance is created.

Instance  Process  0:*   
contained_in This slot should definitely behave differently for different classes - for example physical objects and information.

Instance  Process  0:1   
simultaneous Two intervals that share start and end points (?). This should be a symmetric relation.

Instance  Process  0:*   
contains Events contained within, but not essential to, a larger event.

Instance  Single_hindlimb_flick, Posterior_Shift_Inward, Hindlimb_Extend_Down, Posterior_Tilt_Down, Scrape/Dig, Scoop, Hind_Limb_Retract_Up, Posterior_Tilt_Up, Hindlimb_Sand_Dump  0:*   
part_of This "part_of" relation usually implies temporal inclusion.

Instance  Dig_egg_chamber  0:1   
start As described in H&E p. 9. H&E give no data regarding any lateral preferences.

Instance  Single_hindlimb_flick  0:*
