a core relation that holds between a part and its whole
Everything is part of itself. Any part of any part of a thing is itself part of that thing. Two distinct things cannot be part of each other.
Occurrents are not subject to change and so parthood between occurrents holds for all the times that the part exists. Many continuants are subject to change, so parthood between continuants will only hold at certain times, but this is difficult to specify in OWL. See https://code.google.com/p/obo-relations/wiki/ROAndTime
Parthood requires the part and the whole to have compatible classes: only an occurrent can be part of an occurrent; only a process can be part of a process; only a continuant can be part of a continuant; only an independent continuant can be part of an independent continuant; only an immaterial entity can be part of an immaterial entity; only a specifically dependent continuant can be part of a specifically dependent continuant; only a generically dependent continuant can be part of a generically dependent continuant. (This list is not exhaustive.) A continuant cannot be part of an occurrent: use 'participates in'. An occurrent cannot be part of a continuant: use 'has participant'. A material entity cannot be part of an immaterial entity: use 'has location'. A specifically dependent continuant cannot be part of an independent continuant: use 'inheres in'. An independent continuant cannot be part of a specifically dependent continuant: use 'bearer of'.

has_part
We use the has_part relation to relate complex qualities to more primitive ones. A complex quality is a collection of qualities. The complex quality cannot exist without the sub-qualities. For example, the quality 'swollen' necessarily comes with the qualities of 'protruding' and 'increased size'.
preceded by
x is preceded by y if and only if the time point at which y ends is before or equivalent to the time point at which x starts. 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_about is a (currently) primitive relation that relates an information artifact to an entity.
7/6/2009 Alan Ruttenberg. Following discussion with Jonathan Rees, and introduction of "mentions" relation. Weaken the is_about relationship to be primitive. We will try to build it back up by elaborating the various subproperties that are more precisely defined. Some currently missing phenomena that should be considered "about" are predications - "The only person who knows the answer is sitting beside me" , Allegory, Satire, and other literary forms that can be topical without explicitly mentioning the topic.

is about
A person's name denotes the person. A variable name in a computer program denotes some piece of memory. Lexically equivalent strings can denote different things, for instance "Alan" can denote different people. In each case of use, there is a case of the denotation relation obtaining, between "Alan" and the person that is being named.
denotes is a primitive, instance-level, relation obtaining between an information content entity and some portion of reality. Denotation is what happens when someone creates an information content entity E in order to specifically refer to something. The only relation between E and the thing is that E can be used to 'pick out' the thing. This relation connects those two together. Freedictionary.com sense 3: To signify directly; refer to specifically
2009-11-10 Alan Ruttenberg. Old definition said the following to emphasize the generic nature of this relation. We no longer have 'specifically denotes', which would have been primitive, so make this relation primitive. g denotes r =def r is a portion of reality there is some c that is a concretization of g every c that is a concretization of g specifically denotes r

An investigator reads a protocol and forms a plan to carry out an assay. The plan is a realizable entity (a specifically dependent continuant) that concretizes the protocol (a generically dependent continuant), and both depend on the investigator (an independent continuant).

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)

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

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'.

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.
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.

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.

process(P1) regulates process(P2) iff: P1 results in the initiation or termination of P2 OR affects the frequency of its initiation or termination OR affects the magnitude or rate of output of P2.
We use 'regulates' here to specifically imply control. However, many colloquial usages of the term correctly correspond to the weaker relation of 'causally upstream of or within' (aka influences). Consider relabeling to make things more explicit
Regulation precludes parthood; the regulatory process may not be within the regulated process.

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.

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.

A relationship that holds between two entities in which the processes executed by the two entities are causally connected.
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.
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.

The entity A, immediately upstream of the entity B, has an activity that regulates an activity performed by B. For example, A and B may be gene products and binding of B by A regulates the kinase activity of B. A and B can be physically interacting but not necessarily. Immediately upstream means there are no intermediate entity between A and B.

BFO 2 Reference: In all areas of empirical inquiry we encounter general terms of two sorts. First are general terms which refer to universals or types:animaltuberculosissurgical procedurediseaseSecond, are general terms used to refer to groups of entities which instantiate a given universal but do not correspond to the extension of any subuniversal of that universal because there is nothing intrinsic to the entities in question by virtue of which they – and only they – are counted as belonging to the given group. Examples are: animal purchased by the Emperortuberculosis diagnosed on a Wednesdaysurgical procedure performed on a patient from Stockholmperson identified as candidate for clinical trial #2056-555person who is signatory of Form 656-PPVpainting by Leonardo da VinciSuch terms, which represent what are called ‘specializations’ in [81
Entity doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example Werner Ceusters 'portions of reality' include 4 sorts, entities (as BFO construes them), universals, configurations, and relations. It is an open question as to whether entities as construed in BFO will at some point also include these other portions of reality. See, for example, 'How to track absolutely everything' at http://www.referent-tracking.com/_RTU/papers/CeustersICbookRevised.pdf
An entity is anything that exists or has existed or will exist. (axiom label in BFO2 Reference: [001-001])
entity
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.
BFO 2 Reference: Continuant entities are entities which can be sliced to yield parts only along the spatial dimension, yielding for example the parts of your table which we call its legs, its top, its nails. ‘My desk stretches from the window to the door. It has spatial parts, and can be sliced (in space) in two. With respect to time, however, a thing is a continuant.’ [60, p. 240
Continuant doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example, in an expansion involving bringing in some of Ceuster's other portions of reality, questions are raised as to whether universals are continuants
A continuant is an entity that persists, endures, or continues to exist through time while maintaining its identity. (axiom label in BFO2 Reference: [008-002])
if b is a continuant and if, for some t, c has_continuant_part b at t, then c is a continuant. (axiom label in BFO2 Reference: [126-001])
if b is a continuant and if, for some t, cis continuant_part of b at t, then c is a continuant. (axiom label in BFO2 Reference: [009-002])

continuant
An entity that has temporal parts and that happens, unfolds or develops through time.
BFO 2 Reference: every occurrent that is not a temporal or spatiotemporal region is s-dependent on some independent continuant that is not a spatial region
BFO 2 Reference: s-dependence obtains between every process and its participants in the sense that, as a matter of necessity, this process could not have existed unless these or those participants existed also. A process may have a succession of participants at different phases of its unfolding. Thus there may be different players on the field at different times during the course of a football game; but the process which is the entire game s-depends_on all of these players nonetheless. Some temporal parts of this process will s-depend_on on only some of the players.
Occurrent doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. An example would be the sum of a process and the process boundary of another process.
Simons uses different terminology for relations of occurrents to regions: Denote the spatio-temporal location of a given occurrent e by 'spn[e]' and call this region its span. We may say an occurrent is at its span, in any larger region, and covers any smaller region. Now suppose we have fixed a frame of reference so that we can speak not merely of spatio-temporal but also of spatial regions (places) and temporal regions (times). The spread of an occurrent, (relative to a frame of reference) is the space it exactly occupies, and its spell is likewise the time it exactly occupies. We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame.
An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region. (axiom label in BFO2 Reference: [077-002])

p is a process = Def. p is an occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t. (axiom label in BFO2 Reference: [083-003])
BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps. Lives of organisms are process units, but they too unfold in a continuous series from other, prior processes such as fertilization, and they unfold in turn in continuous series of post-life processes such as post-mortem decay. Clear examples of boundaries of processes are almost always of the fiat sort (midnight, a time of death as declared in an operating theater or on a death certificate, the initiation of a state of war)

BFO 2 Reference: One major family of examples of non-rigid universals involves roles, and ontologies developed for corresponding administrative purposes may consist entirely of representatives of entities of this sort. Thus ‘professor’, defined as follows,b instance_of professor at t =Def. there is some c, c instance_of professor role & c inheres_in b at t.denotes a non-rigid universal and so also do ‘nurse’, ‘student’, ‘colonel’, ‘taxpayer’, and so forth. (These terms are all, in the jargon of philosophy, phase sortals.) By using role terms in definitions, we can create a BFO conformant treatment of such entities drawing on the fact that, while an instance of professor may be simultaneously an instance of trade union member, no instance of the type professor role is also (at any time) an instance of the type trade union member role (any more than any instance of the type color is at any time an instance of the type length).If an ontology of employment positions should be defined in terms of roles following the above pattern, this enables the ontology to do justice to the fact that individuals instantiate the corresponding universals – professor, sergeant, nurse – only during certain phases in their lives.
b is a role means: b is a realizable entity & b exists because there is some single bearer that is in some special physical, social, or institutional set of circumstances in which this bearer does not have to be& b is not such that, if it ceases to exist, then the physical make-up of the bearer is thereby changed.

If, for example, it is correct to conceive geological layers of the Earth as fiat object parts of the Earth, then even though these layers were first delineated in recent times, still existed long before such delineation and what holds of these layers (for example that the oldest layers are also the lowest layers) did not begin to hold because of our acts of delineation.Treatment of material entity in BFOExamples viewed by some as problematic cases for the trichotomy of fiat object part, object, and object aggregate include: a mussel on (and attached to) a rock, a slime mold, a pizza, a cloud, a galaxy, a railway train with engine and multiple carriages, a clonal stand of quaking aspen, a bacterial community (biofilm), a broken femur. Note that, as Aristotle already clearly recognized, such problematic cases – which lie at or near the penumbra of instances defined by the categories in question – need not invalidate these categories. The existence of grey objects does not prove that there are not objects which are black and objects which are white; the existence of mules does not prove that there are not objects which are donkeys and objects which are horses. It does, however, show that the examples in question need to be addressed carefully in order to show how they can be fitted into the proposed scheme, for example by recognizing additional subdivisions [29

BFO 2 Reference: Object, Fiat Object Part and Object Aggregate are not intended to be exhaustive of Material Entity. Users are invited to propose new subcategories of Material Entity.
BFO 2 Reference: ‘Matter’ is intended to encompass both mass and energy (we will address the ontological treatment of portions of energy in a later version of BFO). A portion of matter is anything that includes elementary particles among its proper or improper parts: quarks and leptons, including electrons, as the smallest particles thus far discovered; baryons (including protons and neutrons) at a higher level of granularity; atoms and molecules at still higher levels, forming the cells, organs, organisms and other material entities studied by biologists, the portions of rock studied by geologists, the fossils studied by paleontologists, and so on.Material entities are three-dimensional entities (entities extended in three spatial dimensions), as contrasted with the processes in which they participate, which are four-dimensional entities (entities extended also along the dimension of time).According to the FMA, material entities may have immaterial entities as parts – including the entities identified below as sites; for example the interior (or ‘lumen’) of your small intestine is a part of your body. BFO 2.0 embodies a decision to follow the FMA here.
A material entity is an independent continuant that has some portion of matter as proper or improper continuant part. (axiom label in BFO2 Reference: [019-002])

https://en.wikipedia.org/wiki/ The term body of water most often refers to large accumulations of water, such as oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.

A biome is an ecosystem to which resident ecological communities have evolved adaptations.
There has been some concern raised (see Issue #143) about the usefulness of the assertion that organisms have evolved within a given biome. They may have evolved adaptations elsewhere and demonstrating one or the other is often not feasible. Consider relabelling to "environmental system determined by an ecological community" or similar.
A biome that applies to the terrestrial realm.
An aquatic biome that comprises systems of open-ocean and unprotected coastal habitats, characterized by exposure to wave action, tidal fluctuation, and ocean currents as well as systems that largely resemble these. Water in the marine biome is generally within the salinity range of seawater: 30 to 38 ppt.
A rock is a naturally occurring solid aggregate of one or more minerals or mineraloids.
From https://en.wikipedia.org/wiki/ [A mineral] is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be abiogenic, and to a lesser extent with regards to it having an ordered atomic structure.
Soil is an environmental material which is primarily composed of minerals, varying proportions of sand, silt, and clay, organic material such as humus, gases, liquids, and a broad range of resident micro- and macroorganisms.
The various 'has part' and 'has quality' relations may not hold true for all soils; however, I have yet to find counter examples. Require input from a pedologist or similar. [pbuttigieg]
'In engineering terms, soil is referred to as regolith, or loose rock material that lies above the 'solid geology'. Soil is commonly referred to as "earth" or "dirt"; technically, the term "dirt" should be restricted to displaced soil.' https://en.wikipedia.org/wiki/Soil " The upper limit of soil is the boundary between soil and air, shallow water, live plants, or plant materials that have not begun to decompose. Areas are not considered to have soil if the surface is permanently covered by water too deep (typically more than 2.5 meters) for the growth of rooted plants. The lower boundary that separates soil from the nonsoil underneath is most difficult to define. Soil consists of horizons near the Earth's surface that, in contrast to the underlying parent material, have been altered by the interactions of climate, relief, and living organisms over time. Commonly, soil grades at its lower boundary to hard rock or to earthy materials virtually devoid of animals, roots, or other marks of biological activity. For purposes of classification, the lower boundary of soil is arbitrarily set at 200 cm." Soil taxonomy, 2nd Ed., quoted in http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/edu/?cid=nrcs142p2_054280
A significant accumulation of water which is part of a marine biome.
Ideas like "significant" are fuzzy and need to be modelled more accurately. The definition is a candidate for review.

The mixture of gases (roughly (by molar content/volume: 78% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, trace amounts of other gases, and a variable amount (average around 1%) of water vapor) that surrounds the planet Earth.
An environmental material primarily composed of dihydrogen oxide in its liquid form.
Sediment is an environmental substance comprised of any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bedor bottom of a body of water or other liquid.
It is recommended to use a combination of sediment terms to describe a more specific sediment type.
Water which contains a significant concentration of dissolved salts.
The threshold salt concentration for classifying water as saline varies, but typically begins at about 1,000 to 3,000 parts salt per million parts water or 0.1–0.3% salt by weight.
A biome which has its properties and composition determined by a water body and within which most members of resident ecological communities have adapted to life in or on water.
Water which has physicochemical properties that have been determined by the processes occuring in a sea or ocean.
When we have more classes representing the various processes which make seawater seawater, we can further axiomatise this class.
This definition refers to water that is actually in a sea or ocean. This water may have a wide range of salinity levels.
A material entity which determines an environmental system.
A material entity determines an environmental system when its removal would cause the collapse of that system. For example, a seamount determines a seamount environment, acting as its 'hub'. This class is currently being aligned to the Basic Formal Ontology. Following this alignment, its definition and the definitions of its subclasses will be revised.
A group of hydrous aluminium phyllosilicate (phyllosilicates being a subgroup of silicate minerals) minerals (see clay minerals), that are typically less than 2 micrometres in diameter. Clay consists of a variety of phyllosilicate minerals rich in silicon and aluminium oxides and hydroxides which include variable amounts of structural water.
A portion of enriched soil is a portion of soil with elevated levels of some material entity.
This could be demoted to an inferred class if issues with double inheritance arise.
A portion of environmental material is a fiat object part which forms the medium or part of the medium of an environmental system.
A portion of environmental material is a fiat object which forms the medium or part of the medium of an environmental system.
Everything under this parent must be a mass noun. All subclasses are to be understood as being composed primarily of the named entity, rather than restricted to that entity. For example, "ENVO:water" is to be understood as "environmental material composed primarly of some CHEBI:water". This class is currently being aligned to the Basic Formal Ontology. Following this alignment, its definition and the definitions of its subclasses will be revised.
A layer of some material entity which is adjacent to one or more of its external boundaries and directly interacts with its immediate surroundings.
This class is distinct from a geometric surface, which is two-dimensional. The idea of "uppermost" may be problematic. Further, the definition of layer (the superclass of surface in rev 133) references surface. This may be another issue. Perhaps this can be made into an inferred class using 'bounding layer of' some material entity, note that 'bounding layer' implies containment, which may not be valid here.
Airborne solid particles (also called dust or particulate matter (PM)) or liquid droplets.
Should connect to PATO as "quality of an aerosol"
Silt is granular material of a size somewhere between sand and clay whose mineral origin is quartz and feldspar.
https://en.wikipedia.org/wiki/ In the Udden-Wentworth scale (due to Krumbein), silt particles range between 0.0039 to 0.0625 mm, larger than clay but smaller than sand particles. ISO 14688 grades silts between 0.002 mm and 0.063 mm. In actuality, silt is chemically distinct from clay, and unlike clay, grains of silt are approximately the same size in all dimensions; furthermore, their size ranges overlap. Clays are formed from thin plate-shaped particles held together by electrostatic forces, so present a cohesion. According to the U.S. Department of Agriculture Soil Texture Classification system, the sand-silt distinction is made at the 0.05 mm particle size. The USDA system has been adopted by the Food and Agriculture Organization (FAO). In the Unified Soil Classification System (USCS) and the AASHTO Soil Classification system, the sand-silt distinction is made at the 0.075 mm particle size (i.e., material passing the #200 sieve). Silts and clays are distinguished mechanically by their plasticity.
A naturally occurring granular material composed of finely divided rock and mineral particles.
The marine pelagic biome (pelagic meaning open sea) is that of the marine water column, from the surface to the greatest depths.
The neritic epipelagic zone biome comprises the marine water column above a continental shelf.
The oceanic epipelagic zone biome comprises the marine water column offshore, beyond a continental shelf.
The oceanic sea surface microlayer (SML) biome comprises the top 1000 micrometers of the marine surface waters occurring offshore, away from a continental shelf. It is the boundary layer where all exchange occurs between the atmosphere and the ocean. The chemical, physical, and biological properties of the SML differ greatly from the sub-surface water just a few centimeters beneath.

A shrubland biome is a terrestrial biome which includes, across its entire spatial extent, dense groups of shrubs.
An environmental condition is a range of a determinate quality or combination of qualities that are present in an environmental system.
A condition defines a restricted range of a given quality or combination of qualities. If an environment class, E, has_condition C, then all qualities listed in C are restricted to the ranges defined in C in E. This is not intended as a logical conditional.
A montane shrubland biome is a shrubland biome which occurs in regions elevated above sea level and which has community structure determined by elevation-dependent environmental conditions.
A system which has the disposition to environ one or more material entities.
In ENVO's alignment with the Basic Formal Ontology, this class is being considered as a subclass of a proposed BFO class "system". The relation "environed_by" is also under development. Roughly, a system which includes a material entity (at least partially) within its site and causally influences that entity may be considered to environ it. Following the completion of this alignment, this class' definition and the definitions of its subclasses will be revised.
A mineral material is an environmental material which is primarily composed of some substance that is naturally occurring, solid and stable at room temperature, representable by a chemical formula, usually abiogenic, and that has an ordered atomic structure.
Look for "mineral" in a chemical or geochemical ontology to formalise the composed primarily of link. From https://en.wikipedia.org/wiki/ [A mineral] is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be abiogenic, and to a lesser extent with regards to it having an ordered atomic structure.
Water vapour is a vapour which is the gas phase of water.
Perhaps a better relation between water vapour and water can be found in or added to RO?
An atmosphere is a layer of gases surrounding a material body of sufficient mass that is held in place by the gravity of the body.
Atmospheric water vapour is water vapour that is part of an atmosphere.
A large unit of land or water containing a geographically distinct assemblage of species, natural communities, and environmental conditions.
Unlike biomes, ecoregions are geographically defined entities. ENVO's sister project, GAZ, contains terms for instances of ecoregions (e.g. Beringia lowland tundra). Requests for new terms should be directed to GAZ. ENVO will only contain this top-level class. The class' definition is preliminary and will be aligned to BFO.
Ice is water frozen into a solid state. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter its appearance.
Ecozones delineate large areas of a planetary surface within which organisms have been evolving in relative isolation over long periods of time, separated from one another by geographic features, such as oceans, broad deserts, or high mountain ranges, that constitute barriers to migration.
ENVO contains this top-level class, but all instances will be in GAZ. The definition is preliminary and will be aligned to BFO. https://en.wikipedia.org/wiki/ Ecozones correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. Ecozones are characterized by the evolutionary history of the organisms they contain. They are distinct from biomes, also known as major habitat types, which are divisions of the Earth's surface based on life form, or the adaptation of plants and animals to climatic, soil, and other conditions. Biomes are characterized by similar climax vegetation. Each ecozone may include a number of different biomes. A tropical moist broadleaf forest in Central America, for example, may be similar to one in New Guinea in its vegetation type and structure, climate, soils, etc., but these forests are inhabited by plants and animals with very different evolutionary histories.
A layer is a quantity of some material which is spatially continuous, has comparable thickness, and usually covers some surface.
Note that this class does not contain metalimnion as a subclass. The metaliminon is classified as a thermocline.
Class should be populated by inference and asserted subclasses redistributed.
A layer that is part of a marine water body.
An endolithic environment is an environment that exists within solid rock.
An environmental system which has its properties and dynamics determined by saline water.
An environment which has a lower temperature than some local or global average.
The definition of the deprecated 'cold temperature habitat' class, which this class was derived from, quotes an upper threshold of 15 degrees Celsius for 'coldness'.
An anthropogenic environment is an environmental system which is the product of human activity.
Unsatisfactory definition here. Must consider the threshold that makes an environmental system anthropogenic.

This class will eventually be populated by inference, and its asserted subclasses removed.
A montane condition is an environmental condition in which an altitude range falls between mid-altitude forests and the tree line.
The exact level of the tree line varies with local climate, but typically the tree line is found where mean monthly soil temperatures never exceed 10.0 degrees C and the mean annual soil temperatures are around 6.7 degrees C. In the tropics, this region is typified by montane rain forest (above 3,000 ft) while at higher latitudes coniferous forests often dominate.
An altitudinal condition is an environmental condition in which ranges of factors such as temperature, humidity, soil composition, solar irradiation, and tree density vary with ranges in altitude.
Depending on the latitude (and, to a lesser extent, other factors), the actual location of the zones where these conditions are in effect will change.
A layer which is determined by a form of vegetation.
Snow is an environmental material which is primarily composed of flakes of crystalline water ice.
A site which has its extent determined by the presence or influence of one or more components of an environmental system or the processes occurring therein.
Formerly, this class was an experimental class and a subclass of "environmental feature". It is now aligned to BFO. The class was not obsoleted as the core semantics maintained their stability through its transition.
A lentic water body is a water body in which the accumulated water, in its totality, has very little to no directed flow.

Hydrological precipitation is a process during which any product of the condensation of atmospheric water vapour is pulled to the planetary surface by gravity.
"process" is included in the label to make it clear that we are not referring to the precipitated material (e.g. snow, rain, sleet)
hydrological precipitation process

This may not need to be in the atmosphere, also note that "meteor" will do much of the same work.
Similar, in spirit, to landform. This class may need to be split into aerosols and 'pure' volumes of gas.
aeroform
A material entity which is composed of one or more chemical entities and has neither independent shape nor volume but tends to expand indefinitely.
This class is to be populated by inference.
gaseous environmental material
An object which is naturally occuring, bound together by gravitational or electromagnetic forces, and surrounded by space.
Astronomical bodies are usually cohesive, thus the use of the term 'object' sensu BFO 'object'.
astronomical body
A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.
Considerable debate on the definition of planet exists.
planet
An object which is composed of one or more gravitationally bound structures that are associated with a position in space.
If there is only one astronomical body involved, this class is equivalent to ENVO:01000799. This may be problematic with reasoning, but it seems to be true to the rather fuzzy definitions found thus far.

A biosphere is an environmental system which includes, as parts, all the living entities within the gravitational sphere of influence of an astronomical body, and the non-living and dead entities which they interact with.
Whether this class should be grouped with classes such as "hydrosphere" and "cryosphere" requires some discussion.
The gravitational sphere of influence referenced in this class' definition is the Hill sphere: a region in which an object dominates the attraction of satellites despite gravitational perturbations.

An environmental system in which minimal to no anthropisation has occurred and non-human agents are the primary determinants of the system's dynamics and composition.
In most contexts, 'natural' is defined by the lack of intervention or influence by humans and their activities. On Earth, most environments fall on a scale between completely natural and anthropised.
natural environment
A process during which a natural environmental system is altered by human action.
An area may be classified as anthropized even though it looks natural, such as grasslands that have been deforested by humans. It can be difficult to determine how much a site has been anthropized in the case of urbanization because one must be able to estimate the state of the landscape before significant human action.

Requires addition of waves for full axiomatisation. This should be linked to "subatomic particle" with an "or". Note that ENVO represents space as an environmental material (a hard vacuum with sparse material inclusions).
radiation
An environment which is determined by materials which bear significant concentrations of salts.
The thresholds for "significant" concentrations of salts vary widely and thus no committment is made in this class. Subclasses with more explicit thresholds can be made upon request.

Far more axiomatisation can be done should the qualities of metals be added to PATO or a similar quality ontology. However, note that there are many exceptions to the typical qualities of the majority of metals.
While this class allows for some degree of contamination by non-metal substances, the material represented should show at least some of the typical features of a pure metal: hardness (except for liquid metals), opacity, lustre, malleability, fusibility, ductile and good electrical and thermal conductivity.
metallic material
An aerosol which has non-gaseous parts that are primarily composed of liquid droplets.
aerosolised liquids
An aerosol which has non-gaseous parts that are primarily composed of solid particles.

Gas giants are composed of about 90% hydrogen and helium. Jupiter and Saturn are examples of gas giants.
gas planet
An ice is an environmental material which is either frozen or which is maintained in a solid state by gravitational forces or pressure.
This class is defined logically - any material that is frozen is considered a subclass. Note that ice may be formed at very high temperatures, due to gravitational effects and/or pressure.
ice
A planet which has a surface layer that nearly completely or completely covered by water, and which has a substantial portion of its mass composed of water.
An axiom to express that the planet has a 'substantial' proportion of its mass in the form of water wound enhance this class.
While this planetary form is still mostly theoretical, strong candidates exist such as the extrasolar planet GJ 1214 b and ocean planet candidate Kepler-22b.
ocean planet

While this planetary form is still mostly theoretical, strong candidates exist such as OGLE-2005-BLG-390Lb, OGLE-2013-BLG-0341L b and MOA-2007-BLG-192Lb. Pluto was considered an ice planet until its reclassification in 2006 CE. Surface temperatures of ice planets would have to be below 260 K (−13°C) if composed primarily of water, below 180 K (−93°C) if primarily composed of CO2 and ammonia, and below 80 K (−193°C) if composed primarily of methane.
ice planet
A gas planet which has an atmosphere composed primarily of helium.
The placement of this class assumes that some traces of hydrogen are left in the atmosphere. If this is not the case, the axiom on gas planet must be updated.
A helium planet might form via hydrogen evaporation from a gaseous planet orbiting close to a star. Low-mass white dwarfs may transition into objects which are essentially helium planets by hydrogen depletion through mass transfer to a massive object such as a neutron star. Gliese 436 b is a candidate helium planet.

Materials which are usually assessed when appraising geodiversity include minerals, rocks, sediments, fossils, soils and water. Landforms factored into geodiversity metrics typically include folds, faults, and other expressions of morphology or relations between units of earth material. Natural processes that are included in measures of geodiversity are those which either maintain or change materials or geoforms, including tectonics, sediment transport, and pedogenesis. Geodiversity does not usually factor in anthropogenic entities.

The FoodOn product type class is provided as a food product category tree under which new food product categories and food products themselves can be placed. This tree has upper level categories inspired from other product type schemes like the US Code of Federal Regulations. However it has a much greater depth to it than the other product type schemes in an effort to group related products together. The basis of this tree was inherited from the environment ontology (ENVO).

food additive
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. These actions are described from two distinct but related perspectives: (1) biochemical activity, and (2) role as a component in a larger system/process.
Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule.
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
Any process that mediates interactions between a cell and its surroundings. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment.
The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
A biological process represents a specific objective that the organism is genetically programmed to achieve. Biological processes are often described by their outcome or ending state, e.g., the biological process of cell division results in the creation of two daughter cells (a divided cell) from a single parent cell. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.
Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
Note that, in addition to forming the root of the biological process ontology, this term is recommended for use for the annotation of gene products whose biological process is unknown. When this term is used for annotation, it indicates that no information was available about the biological process of the gene product annotated as of the date the annotation was made; the evidence code "no data" (ND), is used to indicate this.
Any process that modulates the frequency, rate or extent of signal transduction.
Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
Any process that modulates the frequency, rate or extent of cell communication. Cell communication is the process that mediates interactions between a cell and its surroundings. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment.
transferase activity, transferring phosphorus-containing groups
Any process that modulates the frequency, rate or extent of a signaling process.
The entirety of a process in which information is transmitted within a biological system. This process begins with an active signal and ends when a cellular response has been triggered.

The function of interacting (directly or indirectly) with receptors such that the proportion of receptors in the active form is increased.
Any process that modulates the frequency, rate or extent of protein binding.
The activity of a gene product that interacts with a receptor to effect a change in the activity of the receptor. Ligands may be produced by the same, or different, cell that expresses the receptor. Ligands may diffuse extracellularly from their point of origin to the receiving cell, or remain attached to an adjacent cell surface (e.g. Notch ligands).
Any process that modulates the frequency, rate or extent of a response to a stimulus. Response to stimulus is a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus.
Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.
Any process that modulates the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
regulation of cellular physiological process
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism.
Any process that modulates the frequency, rate or extent of binding, the selective interaction of a molecule with one or more specific sites on another molecule.
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus by a cell and ends with a change in state or activity or the cell.
Any process that modulates a measurable attribute of any biological process, quality or function.
Any process that modulates the frequency, rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding.
A molecular function that modulates the activity of a gene product or complex. Examples include enzyme regulators and channel regulators.
Any process that modulates the frequency, rate or extent of a protein or other molecule binding to a receptor.

A quality of an information bearer that imparts the information content
information carrier
data item
Data items include counts of things, analyte concentrations, and statistical summaries.
a data item is an information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements.
2/2/2009 Alan and Bjoern discussing FACS run output data. This is a data item because it is about the cell population. Each element records an event and is typically further composed a set of measurment data items that record the fluorescent intensity stimulated by one of the lasers.
2009-03-16: data item deliberatly ambiguous: we merged data set and datum to be one entity, not knowing how to define singular versus plural. So data item is more general than datum.
2009-03-16: removed datum as alternative term as datum specifically refers to singular form, and is thus not an exact synonym.
2014-03-31: See discussion at http://odontomachus.wordpress.com/2014/03/30/aboutness-objects-propositions/
JAR: datum -- well, this will be very tricky to define, but maybe some information-like stuff that might be put into a computer and that is meant, by someone, to denote and/or to be interpreted by some process... I would include lists, tables, sentences... I think I might defer to Barry, or to Brian Cantwell Smith JAR: A data item is an approximately justified approximately true approximate belief

2009/10/23 Alan Ruttenberg. The intention is that this term represent collections of like data. So this isn't for, e.g. the whole contents of a cel file, which includes parameters, metadata etc. This is more like java arrays of a certain rather specific type
2014-05-05: Data sets are aggregates and thus must include two or more data items. We have chosen not to add logical axioms to make this restriction.

centrally registered identifier symbol
An information content entity that consists of a CRID symbol and additional information about the CRID registry to which it belongs.
2014-05-05: In defining this term we take no position on what the CRID denotes. In particular do not assume it denotes a *record* in the CRID registry (since the registry might not have 'records').
Alan, IAO call 20101124: potentially the CRID denotes the instance it was associated with during creation.
Note, IAO call 20101124: URIs are not always CRID, as not centrally registered. We acknowledge that CRID is a subset of a larger identifier class, but this subset fulfills our current needs. OBI PURLs are CRID as they are registered with OCLC. UPCs (Universal Product Codes from AC Nielsen)are not CRID as they are not centrally registered.

leave one out cross validation method
A k-means clustering is a data transformation which achieves a class discovery or partitioning objective, which takes as input a collection of objects (represented as points in multidimensional space) and which partitions them into a specified number k of clusters. The algorithm attempts to find the centers of natural clusters in the data. The most common form of the algorithm starts by partitioning the input points into k initial sets, either at random or using some heuristic data. It then calculates the mean point, or centroid, of each set. It constructs a new partition by associating each point with the closest centroid. Then the centroids are recalculated for the new clusters, and the algorithm repeated by alternate applications of these two steps until convergence, which is obtained when the points no longer switch clusters (or alternatively centroids are no longer changed).
k-means clustering
A hierarchical clustering is a data transformation which achieves a class discovery objective, which takes as input data item and builds a hierarchy of clusters. The traditional representation of this hierarchy is a tree (visualized by a dendrogram), with the individual input objects at one end (leaves) and a single cluster containing every object at the other (root).
hierarchical clustering

class discovery data transformation
A class discovery objective (sometimes called unsupervised classification) is a data transformation objective where the aim is to organize input data (typically vectors of attributes) into classes, where the number of classes and their specifications are not known a priori. Depending on usage, the class assignment can be definite or probabilistic.
class discovery objective
A class prediction objective (sometimes called supervised classification) is a data transformation objective where the aim is to create a predictor from training data through a machine learning technique. The training data consist of pairs of objects (typically vectors of attributes) and class labels for these objects. The resulting predictor can be used to attach class labels to any valid novel input object. Depending on usage, the prediction can be definite or probabilistic. A classification is learned from the training data and can then be tested on test data.
class prediction objective

collection of organisms
This a general term that can include every organism of a species living in an area or any subset of them. Subclasses can be more specific as needed.
A collection of organisms, all of the same species, that live in the same place.
It is sometimes difficult to define the physical boundaries of a population. In the case of sexually reproducing organisms, the individuals within a population have the potential to reproduce with one another during the course of their lifetimes. 'Community', as often used to describe a group of humans, is a type of population of organisms. Classes for population already exist in IDO ('organism population', IDO_0000509) and OBI ('population', OBI_0000181). The definitions should be standardized across OBO Foundry ontologies and only one term used.
population of organisms
A community of at least two different species, living in a particular area. Must have at least two populations of different species as members.
A multi-species collection of organisms of at least two different species, living in a particular area. Must have at least two populations of different species as members.
multispecies community
Ecological community is defined broadly here, but includes both ecological interactions (inherited from parent term community) and spatial co-existence. It may be used to describe every organisms living in an area, but is often used to refer only to organisms of a particular taxon or guild (e.g., the plant community, the insect community, the herbivore community). The word community, as it often used to describe a group of humans living together, is a type of single-species collection of organisms, not an ecological community.
ecological community
A collection of organisms that has as parts every organism of given species and no organisms of any other species.
At the moment there is no way to specify in an OWL axiom that the collection includes every individual of a species. This should be added, if possible.
This term is neutral with respect to which organisms are included in a species. Membership will depend on the species concept and the taxonomic assertions used to define the species. These criteria must be specified by the user.
species as a collection of organisms
A material entity that has as parts two or more organisms, viruses, or viroids of the same species and no members of any other species.
collection of organisms of the same species
single-species collection of organisms
A collection of organisms of the same species whose members are all either genealogically related to each other or have mated with each other.
community
A collection of organisms that consists of two or more organisms from at least two species.
Need to add axiom to specify that it has at a mimum members of two different species, but not sure how to specify that. Can't say "('has member' only ('member of' min 2 'species as a collection of organisms'))".
multi-species collection of organisms
A material entity that is one or more organisms, viruses or viroids.
organismal entity
A plant experimental condition (PECO:0007359) or set of conditions describing the application of an abiotic (PECO:0007191) or biotic plant exposure (PECO:0007357) or the combinatorial application thereof.

example to be eventually removed
The term was used in an attempt to structure part of the ontology but in retrospect failed to do a good job
failed exploratory term
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.
metadata complete
term created to ease viewing/sort terms for development purpose, and will not be included in a release
organizational term
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."
ready for release
Class is being worked on; however, the metadata (including definition) are not complete or sufficiently clear to the branch editors.
metadata incomplete
Nothing done yet beyond assigning a unique class ID and proposing a preferred term.
uncurated
All definitions, placement in the asserted IS_A hierarchy and required minimal metadata are complete. The class is awaiting a final review by someone other than the term editor.

placeholder removed
An editor note should explain what were the merged terms and the reason for the merge.
terms merged
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 imported
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.
term split
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.

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.
A Formal Theory of Substances, Qualities, and Universals, http://ontology.buffalo.edu/bfo/SQU.pdf
A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal
"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 named class expression is a logical expression that is given a name. The name can be used in place of the expression.
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
Terms with this status should eventually replaced with a term from another ontology.

"Suni, or Jalca, is one of the eight Natural Regions of Peru. It is located in the Andes at an altitude between 3,500 and 4,000 metres above sea level. Suni has a dry and cold weather and there are many glacial valleys. The flora includes gramineous plants and shrubs such as the taya-taya (Caesalpinia spinosa), the quishuar (Buddleja coriacea), and the cantuta (Cantua buxifolia) which was considered sacred by the Incas. Even though it is hard for plants to grow because of the weather, people are able to cultivate such crops as quinoa, qañiwa, broad beans and ulluku (Ullucus tuberosus). The main fauna is the guinea pig and, among numerous other highland birds, the Chiguanco thrush."

GP(X) part_of complex(Y) enables MF(Z) -> X contributes_to Z

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.
inferring direct reg edge from input to regulatory subfunction
inferring direct neg reg edge from input to regulatory subfunction
inferring direct positive reg edge from input to regulatory subfunction
effector input is compound function input
Input of effector is input of its parent MF
if effector directly regulates X, its parent MF directly regulates X
if effector directly positively regulates X, its parent MF directly positively regulates X
if effector directly negatively regulates X, its parent MF directly negatively regulates X
'causally downstream of' and 'overlaps' should be disjoint properties (a SWRL rule is required because these are non-simple properties).
'causally upstream of' and 'overlaps' should be disjoint properties (a SWRL rule is required because these are non-simple properties).
