The OBO Relations Ontology (RO) is a collection of OWL relations (ObjectProperties) intended for use across a wide variety of biological ontologies.

An assertion that holds between an OWL Object Property and a temporal interpretation that elucidates how OWL Class Axioms that use this property are to be interpreted in a temporal context. tooth SubClassOf 'never in taxon' value 'Aves' x never in taxon T if and only if T is a class, and x does not instantiate the class expression "in taxon some T". Note that this is a shortcut relation, and should be used as a hasValue restriction in OWL. Chris Mungall Class: ?X DisjointWith: RO_0002162 some ?Y never in taxon A is mutually_spatially_disjoint_with B if both A and B are classes, and there exists no p such that p is part_of some A and p is part_of some B. non-overlapping with shares no parts with Class: <http://www.w3.org/2002/07/owl#Nothing> EquivalentTo: (BFO_0000050 some ?X) and (BFO_0000050 some ?Y) mutually spatially disjoint with https://github.com/obophenotype/uberon/wiki/Part-disjointness-Design-Pattern An assertion that holds between an ontology class and an organism taxon class, which is intepreted to yield some relationship between instances of the ontology class and the taxon. taxonomic class assertion S ambiguous_for_taxon T if the class S does not have a clear referent in taxon T. An example would be the class 'manual digit 1', which encompasses a homology hypotheses that is accepted for some species (e.g. human and mouse), but does not have a clear referent in Aves - the referent is dependent on the hypothesis embraced, and also on the ontogenetic stage. [PHENOSCPAE:asilomar_mtg] ambiguous for taxon S dubious_for_taxon T if it is probably the case that no instances of S can be found in any instance of T. https://orcid.org/0000-0002-6601-2165 This relation lacks a strong logical interpretation, but can be used in place of never_in_taxon where it is desirable to state that the definition of the class is too strict for the taxon under consideration, but placing a never_in_taxon link would result in a chain of inconsistencies that will take ongoing coordinated effort to resolve. Example: metencephalon in teleost dubious for taxon S present_in_taxon T if some instance of T has some S. This does not means that all instances of T have an S - it may only be certain life stages or sexes that have S https://orcid.org/0000-0002-6601-2165 present in taxon defined by inverse An assertion that involves at least one OWL object that is intended to be expanded into one or more logical axioms. The logical expansion can yield axioms expressed using any formal logical system, including, but not limited to OWL2-DL. logical macro assertion http://purl.obolibrary.org/obo/ro/docs/shortcut-relations/ An assertion that holds between an OWL Annotation Property P and a non-negative integer N, with the interpretation: for any P(i j) it must be the case that | { k : P(i k) } | = N. annotation property cardinality A logical macro assertion whose domain is an IRI for a class The domain for this class can be considered to be owl:Class, but we cannot assert this in OWL2-DL logical macro assertion on a class A logical macro assertion whose domain is an IRI for a property logical macro assertion on a property Used to annotate object properties to describe a logical meta-property or characteristic of the object property. logical macro assertion on an object property logical macro assertion on an annotation property An assertion that holds between an OWL Object Property and a dispositional interpretation that elucidates how OWL Class Axioms or OWL Individuals that use this property are to be interpreted in a dispositional context. For example, A binds B may be interpreted as A have a mutual disposition that is realized by binding to the other one. dispositional interpretation 'pectoral appendage skeleton' has no connections with 'pelvic appendage skeleton' A is has_no_connections_with B if there are no parts of A or B that have a connection with the other. shares no connection with Class: <http://www.w3.org/2002/07/owl#Nothing> EquivalentTo: (BFO_0000050 some ?X) and (RO_0002170 some (BFO_0000050 some ?Y)) has no connections with inherited annotation property Connects an ontology entity (class, property, etc) to a URL from which curator guidance can be obtained. This assertion is inherited in the same manner as functional annotations (e.g. for GO, over SubClassOf and part_of) curator guidance link brain always_present_in_taxon 'Vertebrata' forelimb always_present_in_taxon Euarchontoglires S always_present_in_taxon T if every fully formed member of taxon T has part some S, or is an instance of S This is a very strong relation. Often we will not have enough evidence to know for sure that there are no species within a lineage that lack the structure - loss is common in evolution. However, there are some statements we can make with confidence - no vertebrate lineage could persist without a brain or a heart. All primates are limbed. never lost in always present in taxon This properties were created originally for the annotation of developmental or life cycle stages, such as for example Carnegie Stage 20 in humans. temporal logical macro assertion on a class measurement property has unit has start time value has end time value Count of number of days intervening between the start of the stage and the time of fertilization according to a reference model. Note that the first day of development has the value of 0 for this property. start, days post fertilization Count of number of days intervening between the end of the stage and the time of fertilization according to a reference model. Note that the first day of development has the value of 1 for this property. end, days post fertilization Count of number of years intervening between the start of the stage and the time of birth according to a reference model. Note that the first year of post-birth development has the value of 0 for this property, and the period during which the child is one year old has the value 1. start, years post birth Count of number of years intervening between the end of the stage and the time of birth according to a reference model. Note that the first year of post-birth development has the value of 1 for this property, and the period during which the child is one year old has the value 2 end, years post birth Count of number of months intervening between the start of the stage and the time of birth according to a reference model. Note that the first month of post-birth development has the value of 0 for this property, and the period during which the child is one month old has the value 1. start, months post birth Count of number of months intervening between the end of the stage and the time of birth according to a reference model. Note that the first month of post-birth development has the value of 1 for this property, and the period during which the child is one month old has the value 2 end, months post birth Defines the start and end of a stage with a duration of 1 month, relative to either the time of fertilization or last menstrual period of the mother (to be clarified), counting from one, in terms of a reference model. Thus if month_of_gestation=3, then the stage is 2 month in. month of gestation A relationship between a stage class and an anatomical structure or developmental process class, in which the stage is characterized by the appearance of the structure or the occurrence of the biological process has developmental stage marker Count of number of days intervening between the start of the stage and the time of coitum. For mouse staging: assuming that it takes place around midnight during a 7pm to 5am dark cycle (noon of the day on which the vaginal plug is found, the embryos are aged 0.5 days post coitum) start, days post coitum Count of number of days intervening between the end of the stage and the time of coitum. end, days post coitum start, weeks post birth end, weeks post birth If Rel is the relational form of a process Pr, then it follow that: Rel(x,y) <-> exists p : Pr(p), x subject-partner-in p, y object-partner-in p is asymmetric relational form of process class http://purl.obolibrary.org/obo/ro/docs/interaction-relations/ If Rel is the relational form of a process Pr, then it follow that: Rel(x,y) <-> exists p : Pr(p), x partner-in p, y partner-in p is symmetric relational form of process class http://purl.obolibrary.org/obo/ro/docs/interaction-relations/ R is the relational form of a process if and only if either (1) R is the symmetric relational form of a process or (2) R is the asymmetric relational form of a process is relational form of process class http://purl.obolibrary.org/obo/ro/docs/interaction-relations/ relation p is the direct form of relation q iff p is a subPropertyOf q, p does not have the Transitive characteristic, q does have the Transitive characteristic, and for all x, y: x q y -> exists z1, z2, ..., zn such that x p z1 ... z2n y The general property hierarchy is: "directly P" SubPropertyOf "P" Transitive(P) Where we have an annotation assertion "directly P" "is direct form of" "P" If we have the annotation P is-direct-form-of Q, and we have inverses P' and Q', then it follows that P' is-direct-form-of Q' Chris Mungall is direct form of relation p is the indirect form of relation q iff p is a subPropertyOf q, and there exists some p' such that p' is the direct form of q, p' o p' -> p, and forall x,y : x q y -> either (1) x p y or (2) x p' y Chris Mungall is indirect form of logical macro assertion on an axiom If R <- P o Q is a defining property chain axiom, then it also holds that R -> P o Q. Note that this cannot be expressed directly in OWL is a defining property chain axiom If R <- P o Q is a defining property chain axiom, then (1) R -> P o Q holds and (2) Q is either reflexive or locally reflexive. A corollary of this is that P SubPropertyOf R. is a defining property chain axiom where second argument is reflexive An annotation property that connects an object property to a class, where the object property is derived from or a shortcut property for the class. The exact semantics of this annotation may vary on a case by case basis. is relational form of a class A shortcut relationship that holds between two entities based on their identity criteria logical macro assertion involving identity A shortcut relationship between two entities x and y1, such that the intent is that the relationship is functional and inverse function, but there is no guarantee that this property holds. in approximate one to one relationship with x is approximately equivalent to y if it is the case that x is equivalent, identical or near-equivalent to y The precise meaning of this property is dependent upon some contexts. It is intended to group multiple possible formalisms. Possibilities include a probabilistic interpretation, for example, Pr(x=y) > 0.95. Other possibilities include reified statements of belief, for example, "Database D states that x=y" is approximately equivalent to 'anterior end of organism' is-opposite-of 'posterior end of organism' 'increase in temperature' is-opposite-of 'decrease in temperature' x is the opposite of y if there exists some distance metric M, and there exists no z such as M(x,z) <= M(x,y) or M(y,z) <= M(y,x). is opposite of x is indistinguishable from y if there exists some distance metric M, and there exists no z such as M(x,z) <= M(x,y) or M(y,z) <= M(y,x). is indistinguishable from evidential logical macro assertion on an axiom A relationship between a sentence and an instance of a piece of evidence in which the evidence supports the axiom This annotation property is intended to be used in an OWL Axiom Annotation to connect an OWL Axiom to an instance of an ECO (evidence type ontology class). Because in OWL, all axiom annotations must use an Annotation Property, the value of the annotation cannot be an OWL individual, the convention is to use an IRI of the individual. axiom has evidence A relationship between a sentence and an instance of a piece of evidence in which the evidence contradicts the axiom This annotation property is intended to be used in an OWL Axiom Annotation to connect an OWL Axiom to an instance of an ECO (evidence type ontology class). Because in OWL, all axiom annotations must use an Annotation Property, the value of the annotation cannot be an OWL individual, the convention is to use an IRI of the individual. axiom contradicted by evidence In the context of a particular project, the IRI with CURIE NCBIGene:64327 (which in this example denotes a class) is considered to be representative. This means that if we have equivalent classes with IRIs OMIM:605522, ENSEMBL:ENSG00000105983, HGNC:13243 forming an equivalence set, the NCBIGene is considered the representative member IRI. Depending on the policies of the project, the classes may be merged, or the NCBIGene IRI may be chosen as the default in a user interface context. this property relates an IRI to the xsd boolean value "True" if the IRI is intended to be the representative IRI for a collection of classes that are mutually equivalent. If it is necessary to make the context explicit, an axiom annotation can be added to the annotation assertion is representative IRI for equivalence set OWLAPI Reasoner documentation for representativeElement, which follows a similar idea, but selects an arbitrary member true if the two properties are disjoint, according to OWL semantics. This should only be used if using a logical axiom introduces a non-simple property violation. cjm nominally disjoint with Used to annotate object properties representing a causal relationship where the value indicates a direction.

R is homemorphic for C iff (1) there exists some x,y such that x R y, and x and y instantiate C and (2) for all x, if x is an instance of C, and there exists some y some such that x R y, then it follows that y is an instance of C. cjm 2018-10-21T19:46:34Z R homeomorphic-for C expands to: C SubClassOf R only C.

Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point. 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. is preceded by preceded_by http://www.obofoundry.org/ro/#OBO_REL:preceded_by preceded by precedes x precedes y if and only if the time point at which x ends is before or equivalent to the time point at which y starts.

This relation differs from BFO2:inheres_in in two respects: (1) it does not impose a range constraint, and thus it allows qualities of processes, as well as of information entities, whereas BFO2 restricts inheres_in to only apply to independent continuants (2) it is declared functional, i.e. something can only be a characteristic of one thing. characteristic of bearer of this apple is bearer of this red color this vase is bearer of this fragility Inverse of characteristic_of A bearer can have many dependents, and its dependents can exist for different periods of time, but none of its dependents can exist when the bearer does not exist. bearer_of is bearer of has characteristic participates in this blood clot participates in this blood coagulation this input material (or this output material) participates in this process this investigator participates in this investigation a relation between a continuant and a process, in which the continuant is somehow involved in the process participates_in participates in has participant this blood coagulation has participant this blood clot this investigation has participant this investigator this process has participant this input material (or this output material) a relation between a process and a continuant, in which the continuant is somehow involved in the process Has_participant is a primitive instance-level relation between a process, a continuant, and a time at which the continuant participates in some way in the process.

For each copy of the printed journal there is some quality that carries the journal article, such as a pattern of ink. The journal article (a generically dependent continuant) is concretized as the quality (a specifically dependent continuant), and both depend on that copy of the printed journal (an independent continuant). An investigator reads a protocol and forms a plan to carry out an assay.

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 Most location relations will only hold at certain times, but this is difficult to specify in OWL.

This property and its subproperties are being used primarily for the definition of GO developmental processes. The property hierarchy mirrors the core GO hierarchy. In future we may be able to make do with a more minimal set of properties, but due to the way GO is currently structured we require highly specific relations to avoid incorrect entailments.

Chris Mungall indirectly positively regulates indirectly activates Chris Mungall directly negatively regulates directly inhibits (process to process) directly inhibits Chris Mungall indirectly negatively regulates indirectly inhibits This relation groups causal relations between material entities and causal relations between processes This branch of the ontology deals with causal relations between entities. It is divided into two branches: causal relations between occurrents/processes, and causal relations between material entities. We take an 'activity flow-centric approach', with the former as primary, and define causal relations between material entities in terms of causal relations between occurrents. To define causal relations in an activity-flow type network, we make use of 3 primitives: * Temporal: how do the intervals of the two occurrents relate? * Is the causal relation regulatory? * Is the influence positive or negative The first of these can be formalized in terms of the Allen Interval Algebra. Informally, the 3 bins we care about are 'direct', 'indirect' or overlapping. Note that all causal relations should be classified under a RO temporal relation (see the branch under 'temporally related to'). Note that all causal relations are temporal, but not all temporal relations are causal. Two occurrents can be related in time without being causally connected. We take causal influence to be primitive, elucidated as being such that has the upstream changed, some qualities of the donwstream would necessarily be modified. For the second, we consider a relationship to be regulatory if the system in which the activities occur is capable of altering the relationship to achieve some objective. This could include changing the rate of production of a molecule. For the third, we consider the effect of the upstream process on the output(s) of the downstream process. If the level of output is increased, or the rate of production of the output is increased, then the direction is increased. Direction can be positive, negative or neutral or capable of either direction. Two positives in succession yield a positive, two negatives in succession yield a positive, otherwise the default assumption is that the net effect is canceled and the influence is neutral. Each of these 3 primitives can be composed to yield a cross-product of different relation types. Chris Mungall Do not use this relation directly. It is intended as a grouping for a diverse set of relations, all involving cause and effect. causally related to p is causally upstream of q if and only if p precedes q and p and q are linked in a causal chain Chris Mungall causally upstream of p is immediately causally upstream of q iff both (a) p immediately precedes q and (b) p is causally upstream of q. In addition, the output of p must be an input of q. Chris Mungall immediately causally upstream of p1 directly provides input for p2 iff there exists some c such that p1 has_output c and p2 has_input c This is currently called 'directly provides input for' to be consistent with our terminology where we use 'direct' whenever two occurrents succeed one another directly. We may relabel this simply 'provides input for', as directness is implicit Chris Mungall directly provides input for (process to process) directly provides input for transitive form of directly_provides_input_for Chris Mungall This is a grouping relation that should probably not be used in annotation. Consider instead the child relation 'directly provides input for' (which may later be relabeled simply to 'provides input for') transitively provides input for (process to process) transitively provides input for p 'causally upstream or within' q iff (1) the end of p is before the end of q and (2) the execution of p exerts some causal influence over the outputs of q; i.e. if p was abolished or the outputs of p were to be modified, this would necessarily affect q.

For example, A and B are gene products where the catalytic activity of A regulates the kinase activity of B. Vasundra Touré regulates activity of The entity A has an activity that regulates the quantity or abundance or concentration of the entity B. Vasundra Touré regulates quantity of The entity A is not immediately upstream of the entity B but A has an activity that regulates an activity performed by B. Vasundra Touré indirectly regulates activity of The entity A has an activity that down-regulates by repression the quantity of B. The down-regulation is due to A having an effect on an intermediate entity (typically a DNA or mRNA element) which can produce B. For example, protein A (transcription factor) indirectly decreases by repression the quantity of protein B (gene product) if and only if A negatively regulates the process of transcription or translation of a nucleic acid element that produces B. Vasundra Touré decreases by repression quantity of The entity A has an activity that up-regulates by expression the quantity of B. The up-regulation is due to A having an effect on an intermediate entity (typically a DNA or mRNA element) which can produce B. For example, protein A (transcription factor) indirectly increases by expression the quantity of protein B (gene product) if and only if A positively regulates the process of transcription or translation of a nucleic acid element that produces B. Vasundra Touré increases by expression quantity of The entity A has an activity that directly positively regulates the quantity of B. Vasundra Touré directly positively regulates quantity of The entity A has an activity that directly negatively regulates the quantity of B.

PMID:24138933 Wikipedia:Infant_mortality 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. independent continuant spatial region An occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t. 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. 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 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. generically dependent continuant function An independent continuant that is spatially extended whose identity is independent of that of other entities and can be maintained through time. material entity immaterial entity Disease disease An exposure event in which a human is exposed to particulate matter in the air. Here the exposure stimulus/stress is the particulate matter, the receptor is the airways and lungs of the human, An exposure event in which a plant is provided with fertilizer. The exposure receptor is the root system of the plant, the stimulus is the fertilizing chemical, the route is via the soil, possibly mediated by symbotic microbes. A process occurring within or in the vicinity of an organism that exerts some causal influence on the organism via the interaction between an exposure stimulus and an exposure receptor. The exposure stimulus may be a process, material entity or condition (for example, lack of nutrients). The exposure receptor can be an organism, organism population or a part of an organism. This class is intended as a grouping for various domain and species-specific exposure classes. The ExO class http://purl.obolibrary.org/obo/ExO_0000002 'exposure event' assumes that all exposures involve stressors, which limits the applicability of this class to 'positive' exposures, e.g. exposing a plant to beneficial growing conditions.
