#chemical_element__element any of the more than 100 known substances (of which 92 occur naturally) that cannot be separated into simpler substances and that singly or in combination constitute all matter

part: #atom
supertype: #substance__matter that which has mass and occupies space; "an atom is the smallest indivisible unit of matter"
supertype: pm#physical_entity_part_or_substance
supertype: pm#physical_entity__object spatial entity made of matter
supertype: dl#physical_endurant__PED
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#individual__particular___supertype_of_1st_order_types all individuals (for concepts or relations) are implicitely or explicitely instance of that type
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#endurant__ED
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#endurant_or_perdurant__ED_or_PD
supertype: dl#quality_or_endurant_or_perdurant__Q_or_ED_or_PD
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: dl#PQ_or_PED_or_PR_or_PD
supertype: dl#quality_or_endurant_or_perdurant__Q_or_ED_or_PD
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
