                    supertype:  sumo#process__proces__physicalsituation  intuitively, 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; sumo#process is not identical to pm#situation because an instance of pm#situation is not necessarily an instance of sumo#physical
