OBO Relations Ontology
An assertion that holds between an OWL Object Property and a string or literal, where the value of the string or literal is a Common Logic sentence of collection of sentences that define the Object Property.
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
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.
Class: <http://www.w3.org/2002/07/owl#Nothing> EquivalentTo: (BFO_0000050 some ?X) and (BFO_0000050 some ?Y)
mutually spatially disjoint with
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.
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
present in taxon
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
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.
'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.
Class: <http://www.w3.org/2002/07/owl#Nothing> EquivalentTo: (BFO_0000050 some ?X) and (RO_0002170 some (BFO_0000050 some ?Y))
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)
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.
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
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.
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.
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.
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
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.
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
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.
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
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)
Count of number of days intervening between the end of the stage and the time of coitum.
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
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
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
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'
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
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
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.
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"
'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).
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).
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.
A relationship between a sentence and an instance of a piece of evidence in which the evidence contradicts the axiom
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
Used to annotate object properties representing a causal relationship where the value indicates a direction. Should be "+", "-" or "0"

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)

Note from NCEAS meeting: consider changing primary label
Example: if we define region of chromosome as any subdivision of a chromosome along its long axis, then we can define a region of chromosome that contains only gene x as 'chromosome region' that coincident_with some 'gene x', where the term gene X corresponds to a genomic sequence.
A relation that applies between a cell(c) and a gene(g) , where the process of 'transcription, DNA templated (GO_0006351)' is occuring in in cell c and that process has input gene g.
x 'cell expresses' y iff: cell(x) AND gene(y) AND exists some 'transcription, DNA templated (GO_0006351)'(t) AND t occurs_in x AND t has_input y
x 'regulates in other organism' y if and only if: (x is the realization of a function to exert an effect on the frequency, rate or extent of y) AND (the agents of x are produced by organism o1 and the agents of y are produced by organism o2).
A relationship that holds between a process that regulates a transport process and the entity transported by that process.
A part of relation that applies only between occurents.
A 'has regulatory component activity' B if A and B are GO molecular functions (GO_0003674), A has_component B and A is regulated by B.
A relationship that holds between a GO molecular function and a component of that molecular function that negatively regulates the activity of the whole. More formally, A 'has regulatory component activity' B iff :A and B are GO molecular functions (GO_0003674), A has_component B and A is negatively regulated by B.
By convention GO molecular functions are classified by their effector function. Internal regulatory functions are treated as components. For example, NMDA glutmate receptor activity is a cation channel activity with positive regulatory component 'glutamate binding' and negative regulatory components including 'zinc binding' and 'magnesium binding'.
has negative regulatory component activity
A relationship that holds between a GO molecular function and a component of that molecular function that positively regulates the activity of the whole. More formally, A 'has regulatory component activity' B iff :A and B are GO molecular functions (GO_0003674), A has_component B and A is positively regulated by B.
By convention GO molecular functions are classified by their effector function and internal regulatory functions are treated as components. So, for example calmodulin has a protein binding activity that has positive regulatory component activity calcium binding activity. Receptor tyrosine kinase activity is a tyrosine kinase activity that has positive regulatory component 'ligand binding'.
has positive regulatory component activity
A has necessary component activity B if A and B are GO molecular functions (GO_0003674), A has_component B and B is necessary for A. For example, ATPase coupled transporter activity has necessary component ATPase activity; transcript factor activity has necessary component DNA binding activity.
A 'has component activity' B if A is A and B are molecular functions (GO_0003674) and A has_component B.
w 'has process component' p if p and w are processes, w 'has part' p and w is such that it can be directly disassembled into into n parts p, p2, p3, ..., pn, where these parts are of similar type.
A relationship that holds between between a receptor and an chemical entity, typically a small molecule or peptide, that carries information between cells or compartments of a cell and which binds the receptor and regulates its effector function.
Holds between p and c when p is a transport process or transporter activity and the outcome of this p is to move c from one location to another.
A relationship between a process and a barrier, where the process occurs in a region spanning the barrier. For cellular processes the barrier is typically a membrane. Examples include transport across a membrane and membrane depolarization.
Process(P2) is directly regulated by process(P1) iff: P1 regulates P2 via direct physical interaction between an agent executing P1 (or some part of P1) and an agent executing P2 (or some part of P2). For example, if protein A has protein binding activity(P1) that targets protein B and this binding regulates the kinase activity (P2) of protein B then P1 directly regulates P2.
Process(P2) is directly negatively regulated by process(P1) iff: P1 negatively regulates P2 via direct physical interaction between an agent executing P1 (or some part of P1) and an agent executing P2 (or some part of P2). For example, if protein A has protein binding activity(P1) that targets protein B and this binding negatively regulates the kinase activity (P2) of protein B then P2 directly negatively regulated by P1.
Process(P2) is directly postively regulated by process(P1) iff: P1 positively regulates P2 via direct physical interaction between an agent executing P1 (or some part of P1) and an agent executing P2 (or some part of P2). For example, if protein A has protein binding activity(P1) that targets protein B and this binding positively regulates the kinase activity (P2) of protein B then P2 is directly postively regulated by P1.
A 'has effector activity' B if A and B are GO molecular functions (GO_0003674), A 'has component activity' B and B is the effector (output function) of B. Each compound function has only one effector activity.
This relation is designed for constructing compound molecular functions, typically in combination with one or more regulatory component activity relations.
A relationship that holds between two images, A and B, where: A depicts X; B depicts Y; X and Y are both of type T' C is a 2 layer image consiting of layers A and B; A and B are aligned in C according to a shared co-ordinate framework so that common features of X and Y are co-incident with each other. Note: A and B may be 2D or 3D. Examples include: the relationship between two channels collected simultaneously from a confocal microscope; the relationship between an image dpeicting X and a painted annotation layer that delineates regions of X; the relationship between the tracing of a neuron on an EM stack and the co-ordinate space of the stack; the relationship between two separately collected images that have been brought into register via some image registration software.

x only in taxon y if and only if x is in taxon y, and there is no other organism z such that y!=z a and x is in taxon z.
The original intent was to treat this as a macro that expands to 'in taxon' only ?Y - however, this is not necessary if we instead have supplemental axioms that state that each pair of sibling tax have a disjointness axiom using the 'in taxon' property - e.g. 'in taxon' some Eukaryota DisjointWith 'in taxon' some Eubacteria

There are two ways to encode this as a shortcut relation. The other possibility to use an annotation assertion between two classes, and expand this to a disjointness axiom.
Note that it would be possible to use the relation to label the relationship between a near infinite number of structures - between the rings of saturn and my left earlobe. The intent is that this is used for parsiomoniously for disambiguation purposes - for example, between siblings in a jointly exhaustive pairwise disjointness hierarchy

w 'has component' p if w 'has part' p and w is such that it can be directly disassembled into into n parts p, p2, p3, ..., pn, where these parts are of similar type.
The definition of 'has component' is still under discussion. The challenge is in providing a definition that does not imply transitivity.
For use in recording has_part with a cardinality constraint, because OWL does not permit cardinality constraints to be used in combination with transitive object properties. In situations where you would want to say something like 'has part exactly 5 digit, you would instead use has_component exactly 5 digit.
has component
A relationship that holds between a biological entity and a phenotype. Here a phenotype is construed broadly as any kind of quality of an organism part, a collection of these qualities, or a change in quality or qualities (e.g. abnormally increased temperature). The subject of this relationship can be an organism (where the organism has the phenotype, i.e. the qualities inhere in parts of this organism), a genomic entity such as a gene or genotype (if modifications of the gene or the genotype causes the phenotype), or a condition such as a disease (such that if the condition inheres in an organism, then the organism has the phenotype).

p results in the developmental progression of s iff p is a developmental process and s is an anatomical structure and p causes s to undergo a change in state at some point along its natural developmental cycle (this cycle starts with its formation, through the mature structure, and ends with its loss).
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. To avoid this, the corresponding genus terms in GO should be declared mutually disjoint.

An experimental relation currently used to connect a feature possessed by an organism (e.g. anatomical structure, biological process, phenotype or quality) to a habitat or environment in which that feature is well suited, adapted or provides a reproductive advantage for the organism. For example, fins to an aquatic environment. Usually this will mean that the structure is adapted for this environment, but we avoid saying this directly - primitive forms of the structure may not have evolved specifically for that environment (for example, early wings were not necessarily adapted for an aerial environment). Note also that this is a statement about the general class of structures - not every instance of a limb need confer an advantage for a terrestrial environment, e.g. if the limb is vestigial.

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.
Do not use this relation directly. It is intended as a grouping for a diverse set of relations, all involving cause and effect.

The relations are provided as a convenient shortcut. Consider using the more expressive processual form to capture your data. In the future, these relations will be linked to their cognate processes through rules.

To Do: decide on scope of this relation - inclusive of computational models in domain, or only physical models? Restricted to linking biological systems and phenomena? Inclusive of only diseases in range, or broader?
The driving use case for this relation was to link a biological model system such as a cell line or model organism to a disease it is used to investigate, in virtue of the model system exhibiting features similar to that of the disease of interest.

The genetic variant 'NM_007294.3(BRCA1):c.110C>A (p.Thr37Lys)' casues or contributes to the disease 'familial breast-ovarian cancer'. An environment of exposure to arsenic causes or contributes to the phenotype of patchy skin hyperpigmentation, and the disease 'skin cancer'.
A relationship between an entity (e.g. a genotype, genetic variation, chemical, or environmental exposure) and a condition (a phenotype or disease), where the entity has some causal or contributing role that influences the condition.
Note that relationships of phenotypes to organisms/strains that bear them, or diseases they are manifest in, should continue to use RO:0002200 ! 'has phenotype' and RO:0002201 ! 'phenotype of'.
Genetic variations can span any level of granularity from a full genome or genotype to an individual gene or sequence alteration. These variations can be represented at the physical level (DNA/RNA macromolecules or their parts, as in the ChEBI ontology and Molecular Sequence Ontology) or at the abstract level (generically dependent continuant sequence features that are carried by these macromolecules, as in the Sequence Ontology and Genotype Ontology). The causal relations in this hierarchy can be used in linking either physical or abstract genetic variations to phenotypes or diseases they cause or contribute to. Environmental exposures include those imposed by natural environments, experimentally applied conditions, or clinical interventions.

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,
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.

This rule is dubious: added as a quick fix for expected inference in GO-CAM. The problem is most acute for transmembrane proteins, such as receptors or cell adhesion molecules, which have some subfunctions inside the cell (e.g. kinase activity) and some subfunctions outside (e.g. ligand binding). Correct annotation of where these functions occurs leads to incorrect inference about the location of the whole protein. This should probably be weakened to "... -> overlaps"
If a molecular function (X) has a regulatory subfunction, then any gene product which is an input to that subfunction has an activity that directly_regulates X. Note: this is intended for cases where the regaultory subfunction is protein binding, so it could be tightened with an additional clause to specify this.
