Process |
The class of things that happen and have temporal parts or stages. Examples include extended events like a football match or a race, actions like Pursuing and Reading, and biological processes. The formal definition is: anything that occurs in time but is not an Object. Note that a Process may have participants 'inside' it which are Objects, such as the players in a football match. In a 4D ontology, a Process is something whose spatiotemporal extent is thought of as dividing into temporal stages roughly perpendicular to the time-axis.

| Children |
BodyMotion | Any Motion where the agent is an Organism and the patient is a BodyPart. |
| | Closing | The Class of Processes where an aperture is closed in an Object. |
| | Compressing | Forcing some SelfConnectedObject into a smaller space than at the beginning of the action. |
| | DirectionChange | The act of changing the direction in which the patient of the act is oriented. |
| | EngineCranking | Starting an InternalCombustionEngine, in which an electric motor is employed to initiate Rotating of the Crankshaft and Flywheel to the point where Combusion can sustain the rotation. |
| | EngineCycle | A complete cycle of Engine phases, including a repeat of the first phase. In a FourStrokeEngine this means intake, compression, combustion, exhaust and back to intake. |
| | FourStrokeCombustion | In this cycle of a four stroke engine, fuel combusts and piston is pushed downwards. |
| | FourStrokeCompression | In this cycle of a four stroke engine, fuel vapor and air are compressed and ignited. |
| | FourStrokeExhaust | In this cycle of a four stroke engine, exhaust is driven out. During the 1st, 2nd, and 4th stroke the piston is relying on power and the momentum generated by the other pistons. |
| | FourStrokeIntake | In this cycle of a four stroke engine, air and vaporized fuel are drawn in. |
| | GasMotion | Any Motion where the patient is a Gas. This class would cover, in particular, the motion of Air, e.g. a breeze or wind. |
| | GeologicalProcess | The class of activities that are caused by geological forces and affect geological features, and which may affect the biosphere as well. |
| | Irrigating | Irrigating is the process of transporting and applying water to crops by artificial means. |
| | LiquidMotion | Any Motion where the patient is a Liquid. This class would cover, in particular, the flow of Water. |
| | MotionDownward | Motion where an Object is moving toward the ground. |
| | MotionUpward | Motion where an Object is moving away from the ground. |
| | Opening | The Class of Processes where an aperture is created in an Object. Note that the aperture may be created intentionally, as when one opens a door, or unintentionally, as when the ground ruptures in a seismic event. |
| | Pulling | Pulling describe the exertion of force so as to cause or tend to cause motion towards the agent. |
| | Pushing | Pushing describes the exertion of force so as to cause or tend to cause motion away from the agent. |
| | Radiating | Processes in which some form of electromagnetic radiation, e.g. radio waves, light waves, electrical energy, etc., is given off or absorbed by something else. |
| | Reversing | Moving something in such a way that its top becomes its bottom and vice versa. |
| | Rotating | Motion that begins and ends at the same point, because the trajectory of the Motion is circular. |
| | Stretching | Moving two sides of an object in opposite directions so that the object becomes both longer and thinner. |
| | Swarming | |
| | Translocation | Translocation is that class of Motions in which an object moves from one place to another. In the case of round trips, the origin and destination are the same, but the intervening motion passes through other locations. Translocation represents linear motion, in contrast to rotation or other movement in place. A vehicle is not necessary, Ambulating is a kind of Translocation. |
| | Trip | Trip is the subclass of Motions along a TransitRoute or Transitway. |
| | TwoStrokeCompression | The portion of a two stroke engine cycle where combustion occurs, forcing the piston out of the combustion chamber, and the fuel mixture is compressed in the crankcase. |
| | TwoStrokeIntake | The portion of a two stroke engine cycle where the piston moves into the combustion chamber creating a partial vacuum in the crankcase that draws fuel into the crankcase. |
| | TwoStrokeTransfer | The portion of a two stroke engine cycle where the combustion chamber is opened to the crankcase and the exhaust. This allows the exhaust to vent, and the pressurized fuel mixture to enter the combustion chamber. The piston is most fully removed from the combustion chamber at this point. |
| | WeatherProcess | WeatherProcess is the broadest class of processes that involve weather, including weather seasons (not to be confused with instances of SeasonOfYear), weather systems, and short-term weather events. |
