                             supertype:  partially_tangible__partiallytangible  A subcollection of cyc#SpatialThing-Localized and cyc#TemporalThing. Each instance of cyc#PartiallyTangible has a tangible (i.e. material) part and a temporal extent (i.e. it exists in time). It might or might not also have an intangible part. For example, a particular copy of a book is made of matter, has temporal extent, and also has an intangible part: the information content of the text markings on its pages.

                             supertype:  thing  an object seen from a 3D (or endurantist) perspective, i.e. where a spatial entity may have a time independent identity, as opposed for example to the 4D perspective where each spatial entity has an associated time frame; click here and here for details

                       supertype:  tangible  Something which is not intangible, something which is physical, made of matter. It does not matter whether things are real of imaginary. Therefore we consider Mickey Mouse's car and a hippogriff as  tangible things
                          supertype:  temporal_thing  The collection of all things that have temporal extent or location, i.e. things about which one might sensibly ask When? . cyc#TemporalThing thus contains many kinds of things, including events, physical objects, agreements, and abstract pieces of time. Note that cyc#TimePoint is a specialization of cyc#TemporalThing, since time points have temporal location, although they arguably lack temporal extent. Abstract things that are timeless -- such as mathematical sets, attributes, and numbers -- are of course _not_ instances of cyc#TemporalThing.

                          supertype:  thing_playing_some_role  category to classify things according to roles/viewpoints; classification under this category is application-dependant
