IAO_0000116: BFO 2 Reference: In all areas of empirical inquiry we encounter general terms of two sorts. First are general terms which refer to universals or types:animaltuberculosissurgical procedurediseaseSecond, are general terms used to refer to groups of entities which instantiate a given universal but do not correspond to the extension of any subuniversal of that universal because there is nothing intrinsic to the entities in question by virtue of which they – and only they – are counted as belonging to the given group. Examples are: animal purchased by the Emperortuberculosis diagnosed on a Wednesdaysurgical procedure performed on a patient from Stockholmperson identified as candidate for clinical trial #2056-555person who is signatory of Form 656-PPVpainting by Leonardo da VinciSuch terms, which represent what are called ‘specializations’ in [81

BFO_0000180: Occurrent
IAO_0000116: BFO 2 Reference: every occurrent that is not a temporal or spatiotemporal region is s-dependent on some independent continuant that is not a spatial region
IAO_0000116: BFO 2 Reference: s-dependence obtains between every process and its participants in the sense that, as a matter of necessity, this process could not have existed unless these or those participants existed also. A process may have a succession of participants at different phases of its unfolding. Thus there may be different players on the field at different times during the course of a football game; but the process which is the entire game s-depends_on all of these players nonetheless. Some temporal parts of this process will s-depend_on on only some of the players.
IAO_0000116: Occurrent doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. An example would be the sum of a process and the process boundary of another process.
IAO_0000116: Simons uses different terminology for relations of occurrents to regions: Denote the spatio-temporal location of a given occurrent e by 'spn[e]' and call this region its span. We may say an occurrent is at its span, in any larger region, and covers any smaller region. Now suppose we have fixed a frame of reference so that we can speak not merely of spatio-temporal but also of spatial regions (places) and temporal regions (times). The spread of an occurrent, (relative to a frame of reference) is the space it exactly occupies, and its spell is likewise the time it exactly occupies. We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame.
IAO_0000600: An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region.

IAO_0000116: BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps. Lives of organisms are process units, but they too unfold in a continuous series from other, prior processes such as fertilization, and they unfold in turn in continuous series of post-life processes such as post-mortem decay. Clear examples of boundaries of processes are almost always of the fiat sort (midnight, a time of death as declared in an operating theater or on a death certificate, the initiation of a state of war)

IAO_0000116: BFO 2 Reference: ‘Matter’ is intended to encompass both mass and energy (we will address the ontological treatment of portions of energy in a later version of BFO). A portion of matter is anything that includes elementary particles among its proper or improper parts: quarks and leptons, including electrons, as the smallest particles thus far discovered; baryons (including protons and neutrons) at a higher level of granularity; atoms and molecules at still higher levels, forming the cells, organs, organisms and other material entities studied by biologists, the portions of rock studied by geologists, the fossils studied by paleontologists, and so on.Material entities are three-dimensional entities (entities extended in three spatial dimensions), as contrasted with the processes in which they participate, which are four-dimensional entities (entities extended also along the dimension of time).According to the FMA, material entities may have immaterial entities as parts – including the entities identified below as sites; for example the interior (or ‘lumen’) of your small intestine is a part of your body.

BFO_0000179: process-profile
BFO_0000180: ProcessProfile
IAO_0000112: On a somewhat higher level of complexity are what we shall call rate process profiles, which are the targets of selective abstraction focused not on determinate quality magnitudes plotted over time, but rather on certain ratios between these magnitudes and elapsed times. A speed process profile, for example, is represented by a graph plotting against time the ratio of distance covered per unit of time. Since rates may change, and since such changes, too, may have rates of change, we have to deal here with a hierarchy of process profile universals at successive levels
IAO_0000112: One important sub-family of rate process profiles is illustrated by the beat or frequency profiles of cyclical processes, illustrated by the 60 beats per minute beating process of John’s heart, or the 120 beats per minute drumming process involved in one of John’s performances in a rock band, and so on. Each such process includes what we shall call a beat process profile instance as part, a subtype of rate process profile in which the salient ratio is not distance covered but rather number of beat cycles per unit of time. Each beat process profile instance instantiates the determinable universal beat process profile. But it also instantiates multiple more specialized universals at lower levels of generality, selected from rate process profilebeat process profileregular beat process profile3 bpm beat process profile4 bpm beat process profileirregular beat process profileincreasing beat process profileand so on.In the case of a regular beat process profile, a rate can be assigned in the simplest possible fashion by dividing the number of cycles by the length of the temporal region occupied by the beating process profile as a whole. Irregular process profiles of this sort, for example as identified in the clinic, or in the readings on an aircraft instrument panel, are often of diagnostic significance.
IAO_0000112: The simplest type of process profiles are what we shall call ‘quality process profiles’, which are the process profiles which serve as the foci of the sort of selective abstraction that is involved when measurements are made of changes in single qualities, as illustrated, for example, by process profiles of mass, temperature, aortic pressure, and so on.

subclass of: bodily quality
IAO_0000115: A mental quality is a bodily quality that inheres in those structures of the extended organism that are essential for mental functioning.

intentional modality
type: Class
subclass of: mental disposition
IAO_0000112: An example of an intentional modality is the capacity to represent objects of intentionality as unfolding in time or being time contingent.
IAO_0000115: A structural capacity that shapes how an object of intentionality is represented for the subject.
IAO_0000118: intentional mode
IAO_0000118: intentional structure

failed exploratory term
type: NamedIndividual
IAO_0000111: failed exploratory term
IAO_0000115: The term was used in an attempt to structure part of the ontology but in retrospect failed to do a good job
IAO_0000117: Person:Alan Ruttenberg

metadata complete
type: NamedIndividual
IAO_0000111: metadata complete
IAO_0000115: Class has all its metadata, but is either not guaranteed to be in its final location in the asserted IS_A hierarchy or refers to another class that is not complete.

organizational term
type: NamedIndividual
IAO_0000111: organizational term
IAO_0000115: Term created to ease viewing/sort terms for development purpose, and will not be included in a release
IAO_0000115: term created to ease viewing/sort terms for development purpose, and will not be included in a release

ready for release
type: NamedIndividual
IAO_0000111: ready for release
IAO_0000115: Class has undergone final review, is ready for use, and will be included in the next release. Any class lacking "ready_for_release" should be considered likely to change place in hierarchy, have its definition refined, or be obsoleted in the next release. Those classes deemed "ready_for_release" will also derived from a chain of ancestor classes that are also "ready_for_release."

metadata incomplete
type: NamedIndividual
IAO_0000111: metadata incomplete
IAO_0000115: Class is being worked on; however, the metadata (including definition) are not complete or sufficiently clear to the branch editors.

uncurated
type: NamedIndividual
IAO_0000111: uncurated
IAO_0000115: Nothing done yet beyond assigning a unique class ID and proposing a preferred term.

pending final vetting
type: NamedIndividual
IAO_0000111: pending final vetting
IAO_0000115: All definitions, placement in the asserted IS_A hierarchy and required minimal metadata are complete. The class is awaiting a final review by someone other than the term editor.

core
type: NamedIndividual
IAO_0000115: Core is an instance of a grouping of terms from an ontology or ontologies. It is used by the ontology to identify main classes.

terms merged
type: NamedIndividual
IAO_0000111: terms merged
IAO_0000116: An editor note should explain what were the merged terms and the reason for the merge.

term imported
type: NamedIndividual
IAO_0000111: term imported
IAO_0000116: This is to be used when the original term has been replaced by a term imported from an other ontology. An editor note should indicate what is the URI of the new term to use.

term split
type: NamedIndividual
IAO_0000111: term split
IAO_0000116: This is to be used when a term has been split in two or more new terms. An editor note should indicate the reason for the split and indicate the URIs of the new terms created.

universal
type: NamedIndividual
IAO_0000111: universal
IAO_0000116: Hard to give a definition for. Intuitively a "natural kind" rather than a collection of any old things, which a class is able to be, formally. At the meta level, universals are defined as positives, are disjoint with their siblings, have single asserted parents.

defined class
type: NamedIndividual
IAO_0000111: defined class
IAO_0000115: A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal
IAO_0000116: "definitions", in some readings, always are given by necessary and sufficient conditions. So one must be careful (and this is difficult sometimes) to distinguish between defined classes and universal.

named class expression
type: NamedIndividual
IAO_0000111: named class expression
IAO_0000115: A named class expression is a logical expression that is given a name. The name can be used in place of the expression.
IAO_0000116: named class expressions are used in order to have more concise logical definition but their extensions may not be interesting classes on their own. In languages such as OWL, with no provisions for macros, these show up as actuall classes. Tools may with to not show them as such, and to replace uses of the macros with their expansions

to be replaced with external ontology term
type: NamedIndividual
IAO_0000111: to be replaced with external ontology term
IAO_0000115: Terms with this status should eventually replaced with a term from another ontology.

requires discussion
type: NamedIndividual
IAO_0000111: requires discussion
IAO_0000115: A term that is metadata complete, has been reviewed, and problems have been identified that require discussion before release. Such a term requires editor note(s) to identify the outstanding issues.
