sea turtles are not supported entirely onthe limbs; the loggerhead drags her mass by jerky thrusts. H&E p. 4,5.


Template Slots
Slot name Documentation Type Allowed Values/Classes Cardinality Default
start time The first time when an event is happening (holds). This might be an integer or a class.

Any  Temporal_measure  0:1   
distance_traveled Measure of change of position resulting from a locomotion event.

Instance  Distance_measure  0:1   
follows When one interval starts after another ends.

Instance  Process  0:*   
precedes When a temporal interval ends before another starts.

Instance  Process  0:1   
function_of Connects an action to its explantion in terms of a function.

Instance  Functional_explanation  0:1   
instrument Will usually be a body part, but could be a tool.

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

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

Instance  Process  0:*   
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 inverse of part_of. This should be a list of all of the things that claim to be part_of this object.

Instance  Move_LF_in_quadrapedal_gait, Move_RH_in_quadrapedal_gait, Move_RF_in_quadrapedal_gait, Move_LH_in_quadrapedal_gait  0:*   
contained_in This slot should definitely behave differently for different classes - for example physical objects and information.

Instance  Ascend_beach, Wander_over_beach, Return_to_surf, Return_on_same_track  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  Process  0:*   
part_of This "part_of" relation usually implies temporal inclusion.

Instance  Process  0:1   
start Designates a starting point for a cyclic process. This avoids the requirement to represent cyclic processes with a cyclic graph. Not impossible to deal with, but adds unnecessary complexity.

Instance  Action  0:*   
object The "direct" object slot for an action. If a turtle uses a flipper to move stand, the flipper is the instrument, which moves the object - sand. Note: cases of moving a body part may be best treated by assigning the part moved to the object slot, with something more proximal serving as the instrument - move_head ought to be modelled as object:head; instrument:neck.

Instance  Tangible  0:*   
actor An agent (includes living things) causally related to the event termed an action.

Instance  Caretta_caretta  0:*
