sumo#list  a particular ordered n-tuple of items; generally speaking, lists are created by means of the list_fn function, which takes any number of items as arguments and returns a list with the items in the same order; anything, including other lists, may be an item in a list; note too that lists are extensional - two lists that have the same items in the same order are identical; note too that a list (the null_list) may contain no items

     supertype:  pm#description_medium__descriptionmedium  e.g., a syntax, a language, a script, a structure
        supertype:  pm#description  description (content/medium) of an entity or a situation
           supertype:  pm#description_content/medium/container__descriptioncontent/medium/container

                 supertype:  pm#entity  something that can be "involved" in a situation
                    supertype:  pm#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:  cyc#intangible  The collection of things that are not physical -- are not made of, or encoded in, matter. Every cyc#Collection is a cyc#intangible (even if its instances are tangible), and so are some cyc#individuals.  Caution: do not confuse `tangibility' with `perceivability' -- humans can perceive light even though it's intangible--at least in a sense.
                    supertype:  cyc#partially_intangible__partiallyintangible  The collection of things that either are wholly intangible (see cyc#Intangible) or have at least one intangible (i.e. immaterial) part (see cyc#intangibleParts). This includes intangible individuals, such as instances of cyc#Number-General  or cyc#Agreement, as well as non-individuals (all of which are intangible), i.e. instances of cyc#SetOrCollection.  It also includes things that have both tangible and intangible components (see cyc#CompositeTangibleAndIntangibleObject),  such as a printed copy of a newspaper (as its information content is intangible) or a person (as her mental states are intangible).
                       supertype:  pm#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:  pm#collection  something gathering separated things (entities/situations)
        supertype:  pm#non_spatial_object_that_is_not_a_description_content/medium/container
           supertype:  pm#non_spatial_object__nonspatialobject  abstraction or description content/medium/container (a description medium that has some spatial feature is both instance of sumo#object and pm#non_spatial_object
        supertype:  pm#divisible_entity__divisibleentity  many classifications under this category are application-dependant

              supertype:  pm#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:  pm#relation_type  there are three kinds of relation(_types): pm#predicate_type, pm#function_type and sumo#list; both predicates and functions denote sets of ordered n-tuples; the difference between these two classes is that predicates cover formula-forming operators, while functions cover term-forming operators; a list, on the other hand, is a particular ordered n-tuple
     supertype:  pm#1st_order_type__1stordertype__type1  all 1st order types are implicitely or explicitely instance of that 2nd-order type
        supertype:  pm#type  second-order type or more
           supertype:  pm#collection  something gathering separated things (entities/situations)
           supertype:  sumo#abstract__entity_without_spatial_feature  e.g., knowledge, motivation, measure; properties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium; instances of sumo#abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place or time without some physical encoding or embodiment
              supertype:  pm#non_spatial_object__nonspatialobject  abstraction or description content/medium/container (a description medium that has some spatial feature is both instance of sumo#object and pm#non_spatial_object
