An entity that exists in full at any time in which it exists at all, persists through time while maintaining its identity and has no temporal parts.
continuant
An entity that has temporal parts and that happens, unfolds or develops through time.
occurrent
A continuant that is a bearer of quality and realizable entity entities, in which other entities inhere and which itself cannot inhere in anything.
b is an independent continuant = Def. b is a continuant which is such that there is no c and no t such that b s-depends_on c at t. (axiom label in BFO2 Reference: [017-002])

process
disposition
A specifically dependent continuant that inheres in continuant entities 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.
realizable entity
quality
A continuant that inheres in or is borne by other entities. Every instance of A requires some specific instance of B which must always be the same.
b is a relational specifically dependent continuant = Def. b is a specifically dependent continuant and there are n > 1 independent continuants c1, … cn which are not spatial regions are such that for all 1 i < j n, ci and cj share no common parts, are such that for each 1 i n, b s-depends_on ci at every time t during the course of b’s existence (axiom label in BFO2 Reference: [131-004])
b is a specifically dependent continuant = Def. b is a continuant & there is some independent continuant c which is not a spatial region and which is such that b s-depends_on c at every time t during the course of b’s existence. (axiom label in BFO2 Reference: [050-003])
specifically dependent continuant
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.
role
fiat object
fiat object part
object aggregate
site
object
A continuant that is dependent on one or other independent continuant bearers. For every instance of A requires some instance of (an independent continuant type) B but which instance of B serves can change from time to time.
b is a generically dependent continuant = Def. b is a continuant that g-depends_on one or more other entities. (axiom label in BFO2 Reference: [074-001])
generically dependent continuant
function
p is a process boundary =Def. p is a temporal part of a process & p has no proper temporal parts. (axiom label in BFO2 Reference: [084-001])
process boundary
one-dimensional temporal region
An independent continuant that is spatially extended whose identity is independent of that of other entities and can be maintained through time.
material entity
material entity
b is a continuant fiat boundary = Def. b is an immaterial entity that is of zero, one or two dimensions and does not include a spatial region as part. (axiom label in BFO2 Reference: [029-001])
continuant fiat boundary
immaterial entity
two-dimensional continuant fiat boundary
A generically dependent continuant that is about some thing.
information content entity
An information content entity whose concretizations indicate to their bearer how to realize them in a process.
directive information entity
An image is an affine projection to a two dimensional surface, of measurements of some quality of an entity or entities repeated at regular intervals across a spatial range, where the measurements are represented as color and luminosity on the projected on surface.
image
A directive information entity with action specifications and objective specifications as parts that, when concretized, is realized in a process in which the bearer tries to achieve the objectives by taking the actions specified.
plan specification
An information content entity consisting of a two dimensional arrangement of information content entities such that the arrangement itself is about something.

An environmental control function is a function that regulates a contained environment within specified parameter ranges. For example the control of light exposure, humidity and temperature.
environment control function
A device that can be used to restrict the location of material entities over time
container
A material entity that is designed to perform a function in a scientific investigation, but is not a reagent.
device
A material entity that is an individual living system, such as animal, plant, bacteria or virus, that is capable of replicating or reproducing, growth and maintenance in the right environment. An organism may be unicellular or made up, like humans, of many billions of cells divided into specialized tissues and organs.
