sumo#synthetic_substance__syntheticsubstance  any substance that is the result of an intentional_process, i.e. any substance that is created by humans
  closed_exclusion:  sumo#natural_substance
  supertype:  sumo#substance__amount_of_matter___divisible_entity_without_discrete_parts  object in which every part is similar to every other in every relevant respect; more precisely, something is a substance when it has only arbitrary pieces as parts - any part has properties which are similar to those of the whole; note that a substance may nonetheless have physical properties that vary, e.g., the temperature, chemical constitution, density, etc. may change from one part to another; examples: body of water, air, cement
     supertype:  dl#amount_of_matter__M  similar to sumo#substance but does not need to be connected, e.g., "the amount of gold at this moment located in Europe"
        supertype:  pm#physical_entity_part_or_substance
           supertype:  pm#physical_entity__object  spatial entity made of matter

                 supertype:  pm#spatial_object__spatialobject  object which as a direct spatial location, e.g., physical object, spatial region or shape
                    supertype:  sumo#object__entity_with_spatial_feature  spatial object (space, location or physical object) or description medium/container (e.g., string, language, image); in a 4D ontology, an object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis
                       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:  sumo#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:  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#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:  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#entity  something that can be "involved" in a situation
                    supertype:  3D#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:  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:  dl#entity  a category from DOLCE or generalized by a category from DOLCE
                             supertype:  pm#individual__particular___supertype_of_1st_order_types  all individuals (for concepts or relations) are implicitely or explicitely instance of that type

              supertype:  cyc#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:  cyc#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:  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#entity_part
              supertype:  pm#entity_playing_some_role  e.g., an agent, an owner
                 supertype:  pm#entity  something that can be "involved" in a situation
                 supertype:  pm#thing_that_can_be_seen_as_a_relation  usable as relation type
                    supertype:  pm#thing_playing_some_role  category to classify things according to roles/viewpoints; classification under this category is 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:  sumo#self_connected_object  object that does not consist of two or more disconnected parts
        supertype:  sumo#object__entity_with_spatial_feature  spatial object (space, location or physical object) or description medium/container (e.g., string, language, image); in a 4D ontology, an object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis
