However, the BFO relation was replaced by has role at some time, which is not yet part of a stable release. Once the BFO role has been tested and released, it may replace this relation. part of Intended meaning: Ambiguous between continuant-parthood and occurrent-parthood. domain: continuant range: continuant time: at some time domain: occurrent range: occurrent time: atemporal Parthood as a relation between instances: The primitive instance-level relation p part_of p1 is illustrated in assertions such as: this instance of rhodopsin mediated phototransduction part_of this instance of visual perception. This relation satisfies at least the following standard axioms of mereology: reflexivity (for all p, p part_of p); anti-symmetry (for all p, p1, if p part_of p1 and p1 part_of p then p and p1 are identical); and transitivity (for all p, p1, p2, if p part_of p1 and p1 part_of p2, then p part_of p2). Analogous axioms hold also for parthood as a relation between spatial regions. For parthood as a relation between continuants, these axioms need to be modified to take account of the incorporation of a temporal argument. Thus for example the axiom of transitivity for continuants will assert that if c part_of c1 at t and c1 part_of c2 at t, then also c part_of c2 at t. Parthood as a relation between classes: To define part_of as a relation between classes we again need to distinguish the two cases of continuants and processes, even though the explicit reference to instants of time now falls away. For continuants, we have C part_of C1 if and only if any instance of C at any time is an instance-level part of some instance of C1 at that time, as for example in: cell nucleus part_ of cell. http://www.obofoundry.org/ro/#OBO_REL:part_of part of part_of has part Intended meaning: Ambiguous between continuant-parthood and occurrent-parthood. domain: continuant range: continuant time: at some time domain: occurrent range: occurrent time: atemporal has part has_part realized in Intended meaning: domain: realizable entity range: processual entity time: atemporal is realized by realized in realized_in realizes Intended meaning: domain: processual entity range: realizable entity time: atemporal realizes preceded by An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other.

The relation obtains, for example, when this particular process of oxygen exchange across this particular alveolar membrane has_participant this particular sample of hemoglobin at this particular time. Intended meaning: domain: processual entity range: continuant and (not spatial region) time: at some time derives from See also BFO_0001009 derives into location of location of location_of contained in Containment is location not involving parthood, and arises only where some immaterial continuant is involved. Containment obtains in each case between material and immaterial continuants, for instance: lung contained_in thoracic cavity; bladder contained_in pelvic cavity. Hence containment is not a transitive relation. If c part_of c1 at t then we have also, by our definition and by the axioms of mereology applied to spatial regions, c located_in c1 at t. Thus, many examples of instance-level location relations for continuants are in fact cases of instance-level parthood. For material continuants location and parthood coincide. Containment is location not involving parthood, and arises only where some immaterial continuant is involved. To understand this relation, we first define overlap for continuants as follows: c1 overlap c2 at t =def for some c, c part_of c1 at t and c part_of c2 at t. The containment relation on the instance level can then be defined (see definition): Intended meaning: domain: material entity range: spatial region or site (immaterial continuant) contained in contained_in contains Intended meaning: domain: spatial region or site (immaterial continuant) range: material entity contains located in Location as a relation between instances: The primitive instance-level relation c located_in r at t reflects the fact that each continuant is at any given time associated with exactly one spatial region, namely its exact location. Following we can use this relation to define a further instance-level location relation - not between a continuant and the region which it exactly occupies, but rather between one continuant and another. c is located in c1, in this sense, whenever the spatial region occupied by c is part_of the spatial region occupied by c1. Note that this relation comprehends both the relation of exact location between one continuant and another which obtains when r and r1 are identical (for example, when a portion of fluid exactly fills a cavity), as well as those sorts of inexact location relations which obtain, for example, between brain and head or between ovum and uterus http://www.obofoundry.org/ro/#OBO_REL:located_in located in located_in before_or_simultaneous_with <= Primitive instance level timing relation between events simultaneous_with t1 simultaneous_with t2 iff:= t1 before_or_simultaneous_with t2 and not (t1 before t2) before t1 before t2 iff:= t1 before_or_simulataneous_with t2 and not (t1 simultaeous_with t2) during_which_ends Previously had ID http://purl.obolibrary.org/obo/RO_0002122 in test files in sandpit - but this seems to have been dropped from ro-edit.owl at some point.

That can be problematic if plans are changed during their execution. There are however implicit contingencies for protocols that an agent has in his mind that can be considered part of the plan, even if the agent didn't have them in mind before. Therefore, a planned process can diverge from what the agent would have said the plan was before executing it, by adjusting to problems encountered during execution (e.g. choosing another reagent with equivalent properties, if the originally planned one has run out.) 6/11/9: Edited at workshop.

A museum specimen that serves as evidence for a taxonomic identification process bears an evidence role. A role that is borne by some entity as a result of the entity providing evidence to support an assertion. persistent evidence role true An evidence role that persists through time. Could add relation that persistant evidence role is specifically dependent on a museum material samples. Deprecated because we do not need this term. Can use OBI:evidence role. Not clear what it means for an evidence role to persist through time. collecting process true This term is now redundant and is merged with material sampling process http://purl.obolibrary.org/obo/bco_0000022. observing process Observing butterflies during a transect walk. A process in which a person or machine sees or detects a material entity and selects it as worthy of observation, and which has as output an information content entity about the selected material entity. Biocode Commons Ontology Hackathon A trip camera capture of an image of a jaguar is an observation, because it is "selected" by the camera as worthy of obsevation simply by virtue of moving in front of the camera. Seeing three pelicans flying overhead on Christmas day. The information artifact may written or recorded or just be stored in someone's head (specifically depenedent upon that person). In the context of a taxonomic inventory, an observing process may be called a sighting, and is an ad hoc reporting of, typically, a single taxon occurrence, usually motivated by rarity, individual interest in the taxon, or atypicality of circumstances. sighting being there process true This term was originally developed at the Semantics of Biodiversity workshop in 5/2012. It is no longer needed for the BCO. A process of existing in a particular spatio-temporal region. printed report IAO has the term document, which is defined as "A collection of information content entities intended to be understood together as a whole" and has as examples journal article, patent application, laboratory notebook, and book. IAO also has a term for report, but it is not defined. With this term, we want to describe the physical object that corresponds to some information content entity, together with the information content contained in the document or report. This class may be less important for modeling collection data, but could be important for efforts to get hand written (specifically dependent) reports into an electronic (generically dependent) report, and monitoring that process. Biocode Commons Ontology Hackathon a book a field notebook printed observational report A field notebook. A printed report that records the outcome of some observing process. Biocode Commons Ontology Hackathon selecting process A process by which a person or machine decides that a particular material entity as worthy of collection or observation. Biocode Commons Ontology Hackathon Filtering sea water to extract only organisms smaller than a certain size. The criteria for selection may be specified in a protocol or may be ad hoc. deciding which branch to collect for a herbarium specimen submitting process Biocode Commons Ontology Hackathon A planned process whereby a person submits a material sample to an organization. a curator submitting a herbarium speciman to a museum a researcher submitting a water sample to a laboratory storage collection physical extraction process Considered acquisition in OBI, but that is about taking possession. Physical extraction may involve taking pocession, but it may also just involve extraction of something that is already posessed (e.g. of dna from cells). removing a fish from the ocean with a net picking leaves from a plant A process that involves removing a material entity from its original site to another site. removing dna from cells Biocode Commons Ontology Hackathon material sampling process A planned process that includes selecting a material entity for study, physically extracting the material entity, and submitting the material entity to some institution for preservation or study. Consider use of specimen collection from OBI. Biocode Commons Ontology Hackathon collecting event collecting plant parts for herbarium specimens collecting sea water samples as part of Ocean Sampling Day data sampling process true This term has been deprecated until it is determined whether or not it is needed in the BCO. Should probably be replaced by a term from OBI or IAO. statistical sampling process true This term has been deprecated until it is determined whether or not it is needed in the BCO. Should probably be replaced by a term from OBI or IAO. locality description Biocode Commons Ontology Hackathon An information artifact that is about a spatio-temporal region at which a process (such as collecting process, observing process, or material sampling process) occured. Darwin Core needs to describe both the site and time where some activity occurred as an information content entity (e.g., in recording data from a lab notebook),therefore, we made locality description about a spatial temporal region, rather than a site. material sample role Biocode Commons Ontology Hackathon A role that is borne by some material entity and is realized by the material entity being the output of a material sampling process. This term may be replaced by OBI:specimen role. the role borne by a branch when it becomes a herbarium specimen successful material sampling process true A sampling process that has as output some material sample. Do not need this class. By virtue of the existance of the material sample, we know that the sampling process was successful. unsuccessful material sampling process true A material sampling process that has as output exactly zero material samples. Do not need this class. By virtue of the absence of the material sample, we know that the sampling process was unsuccessful. museum collection entity true At the GSC14 hackathon in 09/2012, we decided to deprecate this term. organismal museum collection entity true A museum collections entity that derives from an organismal entity, has a persistent evidence role and 'depends on' a process of collecting. The label for this on the original diagram was 'collection object'. However, not all entities in collections will fit the defition of 'object', so 'collection entity is probably a better name. The relation 'depends on' cannot really be used here. Old BFO has 'inverse depends on', but this is not in the current BFO. See dwc_bfo2_new.owl for the original logical definition. At the GSC14 hackathon in 09/2012, we decided to deprecate this term. museum collection Biocode Commons Ontology Hackathon An object aggregate that has as member part a material sample that is located in museum as a result of a process of curation. Intent is to document biodiversity for research and education. The class museum collection has meaning that is much broader than biological collections. It would probably be better to import this term from another, more general ontology and create a specific subclass for natural history museum collection. The herbarium collection at the New York Botanical Garden. the painting collection at the Louvre Museum organismal museum collection A museum collection that has as member part a material sample that was derived from an organism. Biocode Commons Ontology Hackathon the insect collection at the Smithsonian Institution institution true Replaced by OBI organization. Request institution as synonym in OBI. organismal entity true A material entity that derives from an organism or virus or viroid. This class is understood to mean: A material entity that is either an organism, a part of an organism, a collection of organisms, or a fossil. The relation 'organismal entity derives from organism' was in the original diagram. Subclasses of organismal entity include organism, and It is not clear if it is valid to that an organism derives from an organism (is the derives from relation reflexive?). At the GSC14 hackathon in 09/2012, we decided to deprecate this term. obsolete organism or virus or viroid true This terms was replaced by a term imported from CARO. The original diagram only had organsim, but DWC and GOs both need to include viruses and viroids. material sample A herbarium or museum specimen. Biocode Commons Ontology Hackathon A jar of water, the microbes that were filtered from that water, the DNA extracted from those microbes, a subsample of that DNA. A material entity that has a material sample role. A material entity takes on the material sample role by being the output of a material samping process. That is, is selected for study, collected, and submitted to an institution for preservation or study. Material sample is already in OBI, but with a slightly different meaning. Consider import of OBI:specimen to replace this term. data sample true An information content entity (?) that is the result of some data sampling process. This term has been deprecated until it is determined whether or not it is needed in the BCO. Should probably be replaced by a term from OBI or IAO. statistical sample true This term has been deprecated until it is determined whether or not it is needed in the BCO. Should probably be replaced by a term from OBI or IAO. protocol governed sampling activity true If sampling is a OBI planned process, that captures that it is protocal governed. taxonomic identification process Using BLAST to identify the taxa present in an environmental (metagenomic) sample. Associating a museum specimen with a specific taxonomic concept based on its characters. Using a key to identify a plant in the field. Using DNA barcoding to identify a plant species. Biocode Commons Ontology Hackathon A process by which a material sample is associated with a taxon or taxa. process that yields a material representation of a material entity Biocode Commons Ontology Hackathon Consider term from OBI or IAO. Includes as output rubbings, casts, photographic prints, audio or video tapes. Needs a better name. Current name is the definition. material target of observation A material entity that has a target of observation role, that is, a material entity that is the input of some observing process. Biocode Commons Ontology Hackathon A bird observed during a Christmas Bird Count A bird observed during a transect walk. An lizard observed in the field that is not collected but whose location is recorded in a field notebook. A tree is forest plot that is measured for diameter at breast height (DBH). process that yields an information artifact that is a representation of a material entity Biocode Commons Ontology Hackathon Includes audio recordings and photographs (which are information artifacts). Needs a better name. Current name is the definition. Some instances of term could possibly be replaced by OBI:image acquisition. Maybe request another OBI term for audio recording acquisition. material target of observation role Biocode Commons Ontology Hackathon A role that is borne by some material entity and is realized by the material entity being the input of an observing process. the role borne by a bird during a Christmas Bird Count Obsolete Class entity continuant Definition: An entity [bfo: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. Examples: a heart, a person, the color of a tomato, the mass of a cloud, a symphony orchestra, the disposition of blood to coagulate, the lawn and atmosphere in front of our building Synonyms: endurant dependent_continuant Definition: A continuant [snap:Continuant] that is either dependent on one or other independent continuant [snap:IndependentContinuant] bearers or inheres in or is borne by other entities. disposition Definition: A realizable entity [snap:RealizableEntity] that essentially causes a specific process or transformation in the object [snap:Object] in which it inheres, under specific circumstances and in conjunction with the laws of nature. A general formula for dispositions is: X (object [snap:Object] has the disposition D to (transform, initiate a process) R under conditions C. Examples: the disposition of vegetables to decay when not refrigerated, the disposition of a vase to brake if dropped, the disposition of blood to coagulate, the disposition of a patient with a weakened immune system to contract disease, the disposition of metal to conduct electricity. fiat_object_part Definition: A material entity [snap:MaterialEntity] that is part of an object [snap:Object] but is not demarcated by any physical discontinuities. Examples: upper and lower lobes of the left lung, the dorsal and ventral surfaces of the body, the east side of Saarbruecken, the lower right portion of a human torso Synonyms: fiat substance part function Definition: A realizable entity [snap:RealizableEntity] the manifestation of which is an essentially end-directed activity of a continuant [snap:Continuant] entity in virtue of that continuant [snap:Continuant] entity being a specific kind of entity in the kind or kinds of contexts that it is made for. Examples: the function of a birth canal to enable transport, the function of the heart in the body: to pump blood, to receive de-oxygenated and oxygenated blood, etc., the function of reproduction in the transmission of genetic material, the digestive function of the stomach to nutriate the body, the function of a hammer to drive in nails, the function of a computer program to compute mathematical equations, the function of an automobile to provide transportation, the function of a judge in a court of law generically_dependent_continuant Definition: A continuant [snap:Continuant] that is dependent on one or other independent continuant [snap:IndependentContinuant] bearers. For every instance of A requires some instance of (an independent continuant [snap:IndependentContinuant] type) B but which instance of B serves can change from time to time. Examples: a certain PDF file that exists in different and in several hard drives independent_continuant Definition: A continuant [snap:Continuant] that is a bearer of quality [snap:Quality] and realizable entity [snap:RealizableEntity] entities, in which other entities inhere and which itself cannot inhere in anything. Examples: an organism, a heart, a leg, a person, a symphony orchestra, a chair, the bottom right portion of a human torso, the lawn and atmosphere in front of our building Synonyms: substantial entity material_entity Definition: An independent continuant [snap:IndependentContinuant] that is spatially extended whose identity is independent of that of other entities and can be maintained through time. Note: Material entity [snap:MaterialEntity] subsumes object [snap:Object], fiat object part [snap:FiatObjectPart], and object aggregate [snap:ObjectAggregate], which assume a three level theory of granularity, which is inadequate for some domains, such as biology. Examples: collection of random bacteria, a chair, dorsal surface of the body object Definition: A material entity [snap:MaterialEntity] 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 object [snap:Object] entities is independent of that of other entities and can be maintained through time. Examples: an organism, a heart, a chair, a lung, an apple Synonyms: substance object_aggregate Definition: A material entity [snap:MaterialEntity] that is a mereological sum of separate object [snap:Object] entities and possesses non-connected boundaries. Examples: a heap of stones, a group of commuters on the subway, a collection of random bacteria, a flock of geese, the patients in a hospital Synonyms: substance aggregate object_boundary 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. Definition: An independent continuant [snap:IndependentContinuant] that is a lower dimensional part of a spatial entity, normally a closed two-dimensional surface. Boundaries are those privileged parts of object [snap:Object] entities that exist at exactly the point where the object [snap:Object] is separated off from the rest of the existing entities in the world. 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 Synonyms: substance boundary one_dimensional_region Definition: A spatial region [snap:SpatialRegion] with one dimension. Examples: the part of space that is a line stretching from one end of absolute space to the other, an edge of a cube-shaped part of space quality Definition: A specifically dependent continuant [snap:SpecificallyDependentContinuant] that is exhibited if it inheres in an entity or entities at all (a categorical property). Examples: the color of a tomato, the ambient temperature of air, the circumference of a waist, the shape of a nose, the mass of a piece of gold, the weight of a chimpanzee realizable_entity Comment: If a realizable entity [snap:RealizableEntity] inheres in a continuant [snap:Continuant], this does not imply that it is actually realized. Definition: A specifically dependent continuant [snap:SpecificallyDependentContinuant] that inheres in continuant [snap: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. 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 Definition: A realizable entity [snap:RealizableEntity] the manifestation of which brings about some result or end that is not essential to a continuant [snap:Continuant] in virtue of the kind of thing that it is but that can be served or participated in by that kind of continuant [snap:Continuant] in some kinds of natural, social or institutional contexts. Examples: the role of a person as a surgeon, the role of a chemical compound in an experiment, 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 ingested matter in digestion, the role of a student in a university site Comment: An instance of Site [snap:Site] is a mixture of independent continuant [snap:IndependentContinuant] entities which act as surrounding environments for other independent continuant [snap:IndependentContinuant] entities, most importantly for instances of object [snap:Object]. A site [snap:Site] is typically made of object [snap:Object] or fiat object part [snap:FiatObjectPart] entities and a surrounding medium in which is found an object [snap:Object] occupying the site [snap:Site]. Independent continuant [snap:IndependentContinuant] entities may be associated with others (which, then, are site [snap:Site] entities) through a relation of "occupation". That relation is connected to, but distinct from, the relation of spatial location. Site [snap:Site] entities are not to be confused with spatial region [snap:SpatialRegion] entities. In BFO, site [snap:Site] allows for a so-called relational view of space which is different from the view corresponding to the class spatial region [snap:SpatialRegion] (see the comment on this class). Definition: An independent continuant [snap:IndependentContinuant] consisting of a characteristic spatial shape in relation to some arrangement of other continuant [snap:Continuant] entities and of the medium which is enclosed in whole or in part by this characteristic spatial shape. Site [snap:Site] entities are entities that can be occupied by other continuant [snap:Continuant] entities. Examples: a particular room in a particular hospital, Maria's nostril or her intestines for a variety of bacteria. spatial_region Comment: All instances of continuant [snap:Continuant] are spatial entities, that is, they enter in the relation of (spatial) location with spatial region [snap:SpatialRegion] entities. As a particular case, the exact spatial location of a spatial region [snap:SpatialRegion] is this region itself. Comment: An instance of spatial region [snap:SpatialRegion] is a part of space. All parts of space are spatial region [snap:SpatialRegion] entities and only spatial region [snap:SpatialRegion] entities are parts of space. Space is the entire extent of the spatial universe, a designated individual, which is thus itself a spatial region [snap:SpatialRegion]. Comment: Space and spatial region [snap:SpatialRegion] entities are entities in their own rights which exist independently of any entities which can be located at them. This view of space is sometimes called "absolutist" or "the container view". In BFO, the class site [snap:Site] allows for a so-called relational view of space, that is to say, a view according to which spatiality is a matter of relative location between entities and not a matter of being tied to space. The bridge between these two views is secured through the fact that while instances of site [snap:Site] are not spatial region [snap:SpatialRegion] entities, they are nevertheless spatial entities. Definition: A continuant [snap:Continuant] that is neither bearer of quality [snap:Quality] entities nor inheres in any other entities. Examples: the sum total of all space in the universe, parts of the sum total of all space in the universe specifically_dependent_continuant Definition: A continuant [snap: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. Examples: the mass of a cloud, the smell of mozzarella, the liquidity of blood, the color of a tomato, the disposition of fish to decay, the role of being a doctor, the function of the heart in the body: to pump blood, to receive de-oxygenated and oxygenated blood, etc. Synonyms: property, trope, mode three_dimensional_region Definition: A spatial region [snap:SpatialRegion] with three dimensions. Examples: a cube-shaped part of space, a sphere-shaped part of space two_dimensional_region Definition: A spatial region [snap:SpatialRegion] with two dimensions. Examples: the surface of a cube-shaped part of space, the surface of a sphere-shaped part of space, the surface of a rectilinear planar figure-shaped part of space zero_dimensional_region Definition: A spatial region [snap:SpatialRegion] with no dimensions. Examples: a point connected_spatiotemporal_region Definition: A spatiotemporal region [span:SpatiotemporalRegion] that has temporal and spatial dimensions such that all points within the spatiotemporal region are mediately or immediately connected to all other points within the same spatiotemporal region [span:SpatiotemporalRegion]. Examples: the spatial and temporal location of an individual organism's life, the spatial and temporal location of the development of a fetus connected_temporal_region Definition: A temporal region [span:TemporalRegion] every point of which is mediately or immediately connected with every other point of which. Examples: the 1970s years, the time from the beginning to the end of a heart attack, the time taken up by cellular meiosis fiat_process_part Definition: A processual entity [span:ProcessualEntity] that is part of a process but that does not have bona fide beginnings and endings corresponding to real discontinuities. Examples: chewing during a meal, the middle part of a rainstorm, the worst part of a heart-attack, the most interesting part of Van Gogh's life occurrent Definition: An entity [bfo:Entity] that has temporal parts and that happens, unfolds or develops through time. Sometimes also called perdurants. Examples: the life of an organism, a surgical operation as processual context for a nosocomical infection, the spatiotemporal context occupied by a process of cellular meiosis, the most interesting part of Van Gogh's life, the spatiotemporal region occupied by the development of a cancer tumor Synonyms: perdurant process Definition: A processual entity [span:ProcessualEntity] that is a maximally connected spatiotemporal whole and has bona fide beginnings and endings corresponding to real discontinuities. Examples: the life of an organism, the process of sleeping, the process of cell-division process_aggregate Definition: A processual entity [span:ProcessualEntity] that is a mereological sum of process [span:Process] entities and possesses non-connected boundaries. Examples: the beating of the hearts of each of seven individuals in the room, the playing of each of the members of an orchestra, a process of digestion and a process of thinking taken together process_boundary Definition: A processual entity [span:ProcessualEntity] that is the fiat or bona fide instantaneous temporal process boundary. Examples: birth, death, the forming of a synapse, the onset of REM sleep, the detaching of a finger in an industrial accident, the final separation of two cells at the end of cell-division, the incision at the beginning of a surgery processual_context Comment: An instance of a processual context [span:ProcessualContext] is a mixture of processual entity [span:ProcessualEntity] which stand as surrounding environments for other processual entity [span:ProcessualEntity] entities. The class processual context [span:ProcessualContext] is the analogous among occurrent [span:Occurrent] entities to the class site [snap:Site] among continuant [snap:Continuant] entities. Definition: An occurrent [span:Occurrent] consisting of a characteristic spatial shape inhering in some arrangement of other occurrent [span:Occurrent] entities. Processual context [span:ProcessualContext] entities are characteristically entities at or in which other occurrent [span:Occurrent] entities can be located or occur. Examples: The processual context for a given manipulation occurring as part of an experiment is made of processual entities which occur in parallel, are not necessarily all parts of the experiment themselves and may involve continuant [snap:Continuant] entities which are in the spatial vicinity of the participants in the experiment. processual_entity Definition: An occurrent [span:Occurrent] that exists in time by occurring or happening, has temporal parts and always involves and depends on some entity. Examples: the life of an organism, the process of meiosis, the course of a disease, the flight of a bird scattered_spatiotemporal_region Definition: A spatiotemporal region [span:SpatiotemporalRegion] that has spatial and temporal dimensions and every spatial and temporal point of which is not connected with every other spatial and temporal point of which. Examples: the space and time occupied by the individual games of the World Cup, the space and time occupied by the individual liaisons in a romantic affair scattered_temporal_region Definition: A temporal region [span:TemporalRegion] every point of which is not mediately or immediately connected with every other point of which. Examples: the time occupied by the individual games of the World Cup, the time occupied by the individual liaisons in a romantic affair spatiotemporal_instant Definition: A connected spatiotemporal region [span:ConnectedSpatiotemporalRegion] at a specific moment. Examples: the spatiotemporal region occupied by a single instantaneous temporal slice (part) of a process spatiotemporal_interval Definition: A connected spatiotemporal region [span:ConnectedSpatiotemporalRegion] that endures for more than a single moment of time. Examples: the spatiotemporal region occupied by a process or by a fiat processual part spatiotemporal_region Comment: All instances of occurrent [span:Occurrent] are spatiotemporal entities, that is, they enter in the relation of (spatiotemporal) location with spatiotemporal region [span:SpatiotemporalRegion] entities. As a particular case, the exact spatiotemporal location of a spatiotemporal region [span:SpatiotemporalRegion] is this region itself. Comment: An instance of the spatiotemporal region [span:SpatiotemporalRegion] is a part of spacetime. All parts of spacetime are spatiotemporal region [span:SpatiotemporalRegion] entities and only spatiotemporal region [span:SpatiotemporalRegion] entities are parts of spacetime. In particular, neither spatial region [snap:SpatialRegion] entities nor temporal region [span:TemporalRegion] entities are in BFO parts of spacetime. Spacetime is the entire extent of the spatiotemporal universe, a designated individual, which is thus itself a spatiotemporal region [span:SpatiotemporalRegion]. Spacetime is among occurrents the analogous of space among continuant [snap:Continuant] entities. Comment: Spacetime and spatiotemporal region [span:SpatiotemporalRegion] entities are entities in their own rights which exist independently of any entities which can be located at them. This view of spacetime can be called "absolutist" or "the container view". In BFO, the class processual context [span:ProcessualContext] allows for a so-called relational view of spacetime, that is to say, a view according to which spatiotemporality is a matter of relative location between entities and not a matter of being tied to spacetime. In BFO, the bridge between these two views is secured through the fact that instances of processual context [span:ProcessualContext] are too spatiotemporal entities. Definition: An occurrent [span:Occurrent] at or in which processual entity [span:ProcessualEntity] entities can be located. Examples: the spatiotemporal region occupied by a human life, the spatiotemporal region occupied by the development of a cancer tumor, the spatiotemporal context occupied by a process of cellular meiosis temporal_instant Definition: A connected temporal region [span:ConnectedTemporalRegion] comprising a single moment of time. Examples: right now, the moment at which a finger is detached in an industrial accident, the moment at which a child is born, the moment of death temporal_interval Definition: A connected temporal region [span:ConnectedTemporalRegion] lasting for more than a single moment of time. Examples: any continuous temporal duration during which a process occurs temporal_region Comment: All instances of occurrent [span:Occurrent] are temporal entities, that is, they enter in the relation of (temporal) location with temporal region [span:TemporalRegion] entities. As a particular case, the exact spatiotemporal location of a temporal region [span:TemporalRegion] is this region itself. Continuant [snap:Continuant] entities are not temporal entities in the technical sense just explained; they are related to time in a different way, not through temporal location but through a relation of existence at a time or during a period of time (see continuant [snap:Continuant]. Comment: An instance of temporal region [span:TemporalRegion] is a part of time. All parts of time are temporal region [span:TemporalRegion] entities and only temporal region [span:TemporalRegion] entities are parts of time. Time is the entire extent of the temporal universe, a designated individual, which is thus a temporal region itself. Comment: Time and temporal region [span:TemporalRegion] entities are entities in their own rights which exist independently of any entities which can be located at them. This view of time can be called "absolutist" or "the container view" in analogy to what is traditionally the case with space (see spatial region [snap:SpatialRegion]. Definition: An occurrent [span:Occurrent] that is part of time. Examples: the time it takes to run a marathon, the duration of a surgical procedure, the moment of death example to be eventually removed failed exploratory term Person:Alan Ruttenberg The term was used used in an attempt to structure part of the ontology but in retrospect failed to do a good job metadata complete 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 term created to ease viewing/sort terms for development purpose, and will not be included in a release ready for release 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 Class is being worked on; however, the metadata (including definition) are not complete or sufficiently clear to the branch editors. uncurated Nothing done yet beyond assigning a unique class ID and proposing a preferred term. pending final vetting 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 definition editor. core Core is an instance of a grouping of terms from an ontology or ontologies. It is used by the ontology to identify main classes. PERSON: Alan Ruttenberg PERSON: Melanie Courtot placeholder removed terms merged An editor note should explain what were the merged terms and the reason for the merge. term imported 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 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. other This is to be used if none of the existing instances cover the reason for obsolescence. An editor note should indicate this new reason. We expect to be able to mine these new reasons and add instances as required. universal A Formal Theory of Substances, Qualities, and Universals, http://ontology.buffalo.edu/bfo/SQU.pdf Alan Ruttenberg 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 "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. A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal Alan Ruttenberg named class expression A named class expression is a logical expression that is given a name. The name can be used in place of the expression. Alan Ruttenberg 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 Alan Ruttenberg Terms with this status should eventually replaced with a term from another ontology. group:OBI requires discussion 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. Alan Ruttenberg group:OBI axiom holds for all times ## Elucidation This is used when the statement/axiom is assumed to hold true 'eternally' ## How to interpret (informal) First the "atemporal" FOL is derived from the OWL using the standard interpretation. This axiom is temporalized by embedding the axiom within a for-all-times quantified sentence. The t argument is added to all instantiation predicates and predicates that use this relation. ## Example Class: nucleus SubClassOf: part_of some cell forall t : forall n : instance_of(n,Nucleus,t) implies exists c : instance_of(c,Cell,t) part_of(n,c,t) ## Notes This interpretation is *not* the same as an at-all-times relation relation has no temporal argument ## Elucidation This is used when the first-order logic form of the relation is binary, and takes no temporal argument. ## Example: Class: limb SubClassOf: develops_from some lateral-plate-mesoderm forall t, t2: forall x : instance_of(x,Limb,t) implies exists y : instance_of(y,LPM,t2) develops_from(x,y)
