entity 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 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]) independent continuant spatial region temporal region p is a process = Def. p is an occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t. (axiom label in BFO2 Reference: [083-003]) 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 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 part object aggregate site object 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 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 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 directive information entity that describes an intended process endpoint. When part of a plan specification the concretization is realized in a planned process in which the bearer tries to effect the world so that the process endpoint is achieved. objective specification A directive information entity that describes an action the bearer will take. action specification An information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements. data item A generically dependent continuant that is about some thing. information content entity 1 A scalar measurement datum is a measurement datum that is composed of two parts, numerals and a unit label. scalar measurement datum An information content entity whose concretizations indicate to their bearer how to realize them in a process. directive information entity A data item that is an aggregate of other data items of the same type that have something in common. Averages and distributions can be determined for data sets. data set 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, and that may be concretized as a realizable entity that, if realized, is realized in a process in which the bearer tries to achieve the objectives by taking the actions specified. plan specification A measurement datum is an information content entity that is a recording of the output of a measurement such as produced by a device. measurement datum An information content entity consisting of a two dimensional arrangement of information content entities such that the arrangement itself is about something. figure time stamped measurement datum A data set that is an aggregate of data recording some measurement at a number of time points. The time series data set is an ordered list of pairs of time measurement data and the corresponding measurement data acquired at that time. time sampled measurement data set A process that realizes a plan which is the concretization of a plan specification. planned process A quality of a physical entity that exists through action of continuants at the physical level of organisation in relation to other entities. physical quality A quality which inheres in a continuant. physical object quality
