                       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:  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:  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:  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:  individual__particular___supertype_of_1st_order_types  all individuals (for concepts or relations) are implicitely or explicitely instance of that type
                    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:  length.distance  the linear extent in space from one end to the other; the longest horizontal dimension of something that is fixed in place; "the length of the table was 5 feet"
        supertype:  fundamental_quantity__fundamentalquantity__fundamental_measure__fundamentalmeasure  one of the four quantities that are the basis of systems of measurement
           supertype:  measure__quantity__amount__quantum  how much there is of something that you can measure
              supertype:  attribute_or_quality_or_measure  e.g., mass, mass unit, 1 kg, frequency, [2-3] hz, color, blue, speed, 1 m/s
        supertype:  physical_property  a property used to characterize physical objects
           supertype:  physical_characteristic  this category is for menu-generation purposes
              supertype:  physical/spatial_attribute_or_quality_or_measure  e.g., mass/length/color measure; here are most of the subtypes of #property.attribute, e.g., #visual_property
           supertype:  property.attribute  a basic or essential attribute shared by all members of a class; "a study of the physical properties of atomic particles"
              supertype:  attribute  an abstraction belonging to or characteristic of an entity
                 supertype:  attribute_or_quality_or_measure  e.g., mass, mass unit, 1 kg, frequency, [2-3] hz, color, blue, speed, 1 m/s
        supertype:  dimension  the magnitude of something in a particular direction (especially length or width or height)
           supertype:  magnitude  the property of relative size or extent; "they tried to predict the magnitude of the explosion"
              supertype:  property.attribute  a basic or essential attribute shared by all members of a class; "a study of the physical properties of atomic particles"

                       supertype:  thing_that_can_be_seen_as_a_relation  usable as relation type
