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.

See https://code.google.com/p/obo-relations/wiki/ROAndTime 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 contains located in my brain is located in my head this rat is located in this cage a relation between two independent continuants, the target and the location, in which the target is entirely within the location 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 Most location relations will only hold at certain times, but this is difficult to specify in OWL.

Individual ontologies should provide their own constraints on this abstract relation. For example, in the realm of anatomy this should hold between a vein and an anatomical structure drains 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 x develops from y if and only if either (a) x directly develops from y or (b) there exists some z such that x directly develops from z and z develops from y Chris Mungall David Osumi-Sutherland Melissa Haendel Terry Meehan This is the transitive form of the develops from relation develops from inverse of develops from Chris Mungall David Osumi-Sutherland Terry Meehan develops into Candidate definition: x directly_develops from y if and only if there exists some developmental process (GO:0032502) p such that x and y both participate in p, and x is the output of p and y is the input of p, and a substantial portion of the matter of x comes from y, and the start of x is coincident with or after the end of y.

It is fairly generic, encompassing induction, developmental contribution and direct and transitive develops from developmentally preceded by A faulty traffic light (material entity) whose malfunctioning (a process) is causally upstream of a traffic collision (a process): the traffic light acts upstream of the collision. c acts upstream of p if and only if c enables some f that is involved in p' and p' occurs chronologically before p, is not part of p, and affects the execution of p. c is a material entity and f, p, p' are processes. acts upstream of A gene product that has some activity, where that activity may be a part of a pathway or upstream of the pathway. c acts upstream of or within p if c is enables f, and f is causally upstream of or within p. c is a material entity and p is an process. affects acts upstream of or within Inverse of developmentally preceded by Chris Mungall developmentally succeeded by 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.

Pier Buttigieg adapted for living in A population of xs will possess adaptations (either evolved naturally or via artifical selection) which permit it to exist and grow in y. has habitat has habitat cjm holds between x and y if and only if x is causally upstream of y and the progression of x decreases the frequency, rate or extent of y causally upstream of, negative effect q inheres in part of w if and only if there exists some p such that q inheres in p and p part of w.

It is ended as a grouping for a diverse set of relations, all involving organismal development developmentally related to ATP citrate lyase (ACL) in Arabidopsis: it is a heterooctamer, composed of two types of subunits, ACLA and ACLB in a A(4)B(4) stoichiometry. Neither of the subunits expressed alone give ACL activity, but co-expression results in ACL activity. Both subunits contribute_to the ATP citrate lyase activity. Subunits of nuclear RNA polymerases: none of the individual subunits have RNA polymerase activity, yet all of these subunits contribute_to DNA-dependent RNA polymerase activity. eIF2: has three subunits (alpha, beta, gamma); one binds GTP; one binds RNA; the whole complex binds the ribosome (all three subunits are required for ribosome binding). So one subunit is annotated to GTP binding and one to RNA binding without qualifiers, and all three stand in the contributes_to relationship to "ribosome binding". And all three are part_of an eIF2 complex We would like to say if and only if exists c', p' c part_of c' and c' capable_of p and c capable_of p' and p' part_of p then c contributes_to p However, this is not possible in OWL. We instead make this relation a sub-relation of the two chains, which gives us the inference in the one direction.

Chris Mungall Do not use this relation directly. It is ended as a grouping for a diverse set of relations, all involving branching relationships This relation can be used for geographic features (e.g. rivers) as well as anatomical structures (plant branches and roots, leaf veins, animal veins, arteries, nerves) in branching relationship with https://github.com/obophenotype/uberon/issues/170 Deschutes River tributary_of Columbia River inferior epigastric vein tributary_of external iliac vein x tributary_of y if and only if x a channel for the flow of a substance into y, where y is larger than x. If x and y are hydrographic features, then y is the main stem of a river, or a lake or bay, but not the sea or ocean. If x and y are anatomical, then y is a vein. Chris Mungall drains into drains to tributary channel of http://en.wikipedia.org/wiki/Tributary http://www.medindia.net/glossary/venous_tributary.htm This relation can be used for geographic features (e.g. rivers) as well as anatomical structures (veins, arteries) tributary of http://en.wikipedia.org/wiki/Tributary Deschutes River distributary_of Little Lava Lake x distributary_of y if and only if x is capable of channeling the flow of a substance to y, where y channels less of the substance than x Chris Mungall branch of distributary channel of http://en.wikipedia.org/wiki/Distributary This is both a mereotopological relationship and a relationship defined in connection to processes. It concerns both the connecting structure, and how this structure is disposed to causally affect flow processes distributary of x has developmental potential involving y iff x is capable of a developmental process with output y. y may be the successor of x, or may be a different structure in the vicinity (as for example in the case of developmental induction). Chris Mungall has developmental potential involving x has the potential to develop into y iff x develops into y or if x is capable of developing into y Chris Mungall has potential to develop into x has potential to directly develop into y iff x directly develops into y or x is capable of directly developing into y Chris Mungall has potential to directly develop into inverse of upstream of Chris Mungall causally downstream of 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 '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. We would like to make this disjoint with 'preceded by', but this is prohibited in OWL2 Chris Mungall influences (processual) affects causally upstream of or within inverse of causally upstream of or within Chris Mungall causally downstream of or within c involved in regulation of p if c is involved in some p' and p' regulates some p Chris Mungall involved in regulation of c involved in regulation of p if c is involved in some p' and p' negatively regulates some p Chris Mungall involved in negative regulation of c involved in or regulates p if and only if either (i) c is involved in p or (ii) c is involved in regulation of p OWL does not allow defining object properties via a Union Chris Mungall involved in or reguates involved in or involved in regulation of A relationship that holds between two entities in which the processes executed by the two entities are causally connected. Considering relabeling as 'pairwise interacts with' This relation and all sub-relations can be applied to either (1) pairs of entities that are interacting at any moment of time (2) populations or species of entity whose members have the disposition to interact (3) classes whose members have the disposition to interact. Chris Mungall Note that this relationship type, and sub-relationship types may be redundant with process terms from other ontologies. For example, the symbiotic relationship hierarchy parallels GO. 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. in pairwise interaction with interacts with http://purl.obolibrary.org/obo/MI_0914 https://github.com/oborel/obo-relations/wiki/InteractionRelations An interaction relationship in which at least one of the partners is an organism and the other is either an organism or an abiotic entity with which the organism interacts.

It is intended as a grouping for a diverse set of relations, all involving cause and effect. causal relation between processes Chris Mungall depends on q towards e2 if and only if q is a relational quality such that q inheres-in some e, and e != e2 and q is dependent on e2 This relation is provided in order to support the use of relational qualities such as 'concentration of'; for example, the concentration of C in V is a quality that inheres in V, but pertains to C. Chris Mungall towards The intent is that the process branch of the causal property hierarchy is primary (causal relations hold between occurrents/processes), and that the material branch is defined in terms of the process branch 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. causal relation between entities A coral reef environment is determined by a particular coral reef s determined by f if and only if s is a type of system, and f is a material entity that is part of s, such that f exerts a strong causal influence on the functioning of s, and the removal of f would cause the collapse of s. The label for this relation is probably too general for its restricted use, where the domain is a system. It may be relabeled in future Chris Mungall determined by (system to material entity) Chris Mungall Pier Buttigieg determined by inverse of determined by Chris Mungall determines (material entity to system) determines s 'determined by part of' w if and only if there exists some f such that (1) s 'determined by' f and (2) f part_of w, or f=w.
