     supertype:  oxidation__oxidization__oxidisation  the process of oxidizing; the addition of oxygen to a compound with a loss of electrons; always occurs accompanied by reduction
        supertype:  chemical_reaction__reaction  (chemistry) a process in which one or more substances are changed into others; "there was a chemical reaction of the lime with the ground water"
           supertype:  chemical_process__chemical_change__chemical_action  any process determined by the atomic and molecular composition and structure of the substances involved
              supertype:  natural_process__naturalproces__natural_action__naturalaction__action__activity  a process existing in or produced by nature (rather than by the intent of human beings); "the action of natural forces"; "volcanic activity"
                 supertype:  process__proces  a sustained phenomenon or one marked by gradual changes through a series of states; "events now in process"; "the process of calcification begins later for boys than for girls"

                       supertype:  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
                          supertype:  situation  something that "occurs" in a real/imaginary region of time and space
                             supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                          supertype:  process_or_process_description
                             supertype:  processing_thing
                                supertype:  thing_playing_some_role  category to classify things according to roles/viewpoints; classification under this category is application-dependant
                                   supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                          supertype:  physical__physical_thing  an entity that has a location in space-time; locations are themselves understood to have a location in space-time; click here for more details on the identical category sowa#physical_thing
                             supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
