disjoint with: function
disjoint with: role
comment: Definition: A realizable entity that essentially causes a specific process or transformation in the object in which it inheres, under specific circumstances and in conjunction with the laws of nature. A general formula for dispositions is: X (object) has the disposition D to (transform, initiate a process) R under conditions C.

comment: Definition: A independent continuant that is spatially extended, maximally self-connected and self-contained (the parts of a substance are not separated from each other by spatial gaps) and possesses an internal unity. The identity of substantial objects is independent of that of other entities and can be maintained through time and through loss and gain of parts and qualities.

type: Class
subclass of: independent_continuant

comment: Comment: Boundaries are theoretically difficult entities to account for, however the intuitive notion of a physical boundary as a surface of some sort (whether inside or outside of a thing) will generally serve as a good guide for the use of this universal.
comment: Definition: An independent continuant that is a lower dimensional part of a spatial entity, normally a closed two-dimensional surface. Boundaries are those privileged parts of objects that exist at exactly the point where the object is separated off from the rest of the existing entities in the world.
comment: Examples: the surface of the skin, the surface of the earth, the surface of the interior of the stomach, the outer surface of a cell or cell wall

  union of: function
  union of: role
subclass of: dependent_continuant
comment: Definition: A dependent continuant that inheres in continuants and are not exhibited in full at every time in which it inheres in an entity or group of entities. The exhibition or actualization of a realizable entity is a particular manifestation, functioning or process that occurs under certain circumstances.
comment: Examples: the role of being a doctor, the function of the reproductive organs, the disposition of blood to coagulate, the disposition of metal to conduct electricity

role
type: Class
subclass of: realizable_entity
comment: Definition: A realizable entity the manifestation of which brings about some result or end that is not essential to a continuant in virtue of the kind of thing that it is but that can be served or participated in by that kind of continuant in some kinds of natural, social or institutional contexts.
comment: Examples: the role of a person as a surgeon, the role of an artificial heart in pumping blood, the role of a chemical compound in an experiment, the role of a drug in the treatment of a disease, the role of a patient relative as defined by a hospital administrative form, the role of a woman as a legal mother in the context of system of laws, the role of a biological grandfather as legal guardian in the context of a system of laws, the role of a tree in maintaining stability in an ecosystem, the role of ingested matter in digestion

site
type: Class
subclass of: independent_continuant
comment: Comment: Sites should not be confused with spatial regions. Sites characteristically have a filling or medium and are capable of altering their spatial location (moving from one spatial region to another) without altering their identity.
comment: Definition: An independent continuant consisting of a characteristic spatial shape in relation to some arrangement of other continuants and of the medium which is enclosed in whole or in part by this characteristic spatial shape.

spatiotemporal_region
type: Class
equivalent class: Class
  union of: connected_spatiotemporal_region
  union of: scattered_spatiotemporal_region
subclass of: occurrent
disjoint with: temporal_region
comment: Comment: This is the time and space within which occurrents exist. Occurrents exist in space and time in a different way from that in which continuants do and thus the space and time in which they exist is itself different. Spatiotemporal region's importance is primarily theoretical and it will not be used often in most domain ontology applications.
