Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point. An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other. is preceded by preceded_by http://www.obofoundry.org/ro/#OBO_REL:preceded_by preceded by precedes x precedes y if and only if the time point at which x ends is before or equivalent to the time point at which y starts.

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

See http://purl.obolibrary.org/obo/ro/docs/temporal-semantics/ 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): contained_in obsolete contained in true contains obsolete contains true 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 This is the transitive form of the develops from relation develops from inverse of develops from 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.

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.

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. causally related to relation that links two events, processes, states, or objects such that one event, process, state, or object (a cause) contributes to the production of another event, process, state, or object (an effect) where the cause is partly or wholly responsible for the effect, and the effect is partly or wholly dependent on the cause. https://en.wikipedia.org/wiki/Causality p is causally upstream of q iff p is causally related to q, the end of p precedes the end of q, and p is not an occurrent part of q. causally upstream of p is 'causally upstream or within' q iff p is causally related to q, and the end of p precedes, or is coincident with, the end of q.

ENVO ENVO:00000451 amenity lake A lake constructed, or modified, for the chief purpose of providing an amenity. MA:ma A lake that is long, narrow, and finger-shaped, usually found in a glacial trough. Its formation begins when a glacier moves over an area containing alternate bands of hard and soft bedrock. The sharp-edged boulders carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. On either side of the rock basin, the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars, which act as dams between which rainwater may accumulate after the retreat of the ice age, filling up the rock basin and creating a ribbon lake. A ribbon lake may also form behind a terminal or recessional moraine, both of which also act as dams, enabling water to accumulate behind them. A ribbon lake may also occur if a tributary glacier joins a main glacier. The increase in power can create a trough, which is filled with water from a river/meltwater to create a ribbon lake. https://en.wikipedia.org/wiki/Ribbon_lake ribbon lake A lake that is long, narrow, and finger-shaped, usually found in a glacial trough. Its formation begins when a glacier moves over an area containing alternate bands of hard and soft bedrock. The sharp-edged boulders carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. On either side of the rock basin, the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars, which act as dams between which rainwater may accumulate after the retreat of the ice age, filling up the rock basin and creating a ribbon lake.

Polynyas may contain brash ice and/or be covered with new ice, nilas or young ice; submariners refer to these as skylights. Sometimes the polynya is limited on one side by the coast and is called a shore polynya or by fast ice and is called a flaw polynya. If it recurs in the same position every year, e.g. off the mouths of big rivers, it is called a recurring polynya. A temporary small clearing in pack ice which consists of small floes and brash in continuous local movement is called an unstable polynya; an opening which is flanked by large floes and therefore appears to be relatively stable is called a stable polynya. Polynyas range in size from relatively small to enormous. The largest polynya observed in the Antarctic was the Weddell Polynya of 1975-77, covering an area of 2x105km2. The two main categories of polynya are sensible heat and latent heat, depending on the mechanism responsible for maintaining their presence. Latent heat polynyas are maintained by persistent katabatic winds that drain off the continent. Newly formed ice is advected away by the wind, leaving the surface ice-free and open to more ice formation. In this manner latent heat polynyas can be major sources of new ice production. Coastal polynyas are primarily of this type. Sensible heat polynyas are maintained by upwelling warm water that supplies a sufficiently large oceanic heat flux to the base of the ice to reduce its thickness, or melt it completely. These polynyas are not responsible for large quantities of new ice production. A polynya may also form by a combination of the sensible and latent heat processes. From the remote sensing/sea ice standpoint a polynya is a hole in the ice that ordinarily wouldn't be there - except that either the wind is creating it by pushing the ice away or there is something under the ice that is warmer than its surroundings and melting the ice that would otherwise be there. Could be a subclass of a class that describes holes in solid material covering water or other liquids. Perhaps a class like "clearing".

A palsa consists, similarly to a pingo, of an ice core and overlying soil materials, in case of a palsa usually boggy soil. Palsas are characteristically found in areas with discontinuous permafrost and in such areas bay be the only reliable surface evidence of permafrost. A palsa needs large quantities of water for the formation of its ice core (i.e. ice lens), which is why they frequently emerge from and are bound by boggy soils, which can store enormous quantities of water in their pores.

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."

Parse comment from GCW and new subclases where appropriate. http://sweetontology.net/realmCryo/SeaIce https://en.wikipedia.org/wiki/Sea_ice In the United States, NOAA sea ice operations does not include superstructure icing as being sea ice. In sea ice operations however, sea ice is any form of ice found at sea which has originated from the freezing of sea water. It presents the main kind of floating ice encountered at sea. Except where it forms ridges, sea ice is up to a few metres thick, in which respect it differs from shelf ice. Sea ice may be discontinuous pieces (ice floes) moved on the ocean surface by wind and currents (pack ice), or a motionless sheet attached to the coast (land-fast ice). In brief, it forms first as lolly ice (frazil crystals), thickens into sludge, and coagulates into sheet ice, pancake ice, or into floes of various shapes and sizes. Thereafter, sea ice may develop into pack ice and/or become a form of pressure ice. Sea ice less than one year old is called first-year ice. Perennial ice is sea ice that survives at least one summer. It may be subdivided into second-year ice and multi-year ice, where multiyear ice has survived at least two summers. sea ice In the United States, NOAA sea ice operations does not include superstructure icing as being sea ice.

EcoLexicon:clay SWEETRealm:Clay This definition is intentionally ambiguous to support the multiple thresholds set by different authorities.The distinction between silt and clay varies by discipline. Geologists and soil scientists usually consider the separation to occur at a particle size of 2 μm (clays being finer than silts), sedimentologists often use 4–5 μm, and colloid chemists use 1 μm. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg limits. ISO 14688 grades clay particles as being smaller than 2 μm and silt particles as being larger. Mixtures of sand, silt and less than 40% clay are called loam.

To quote from https://en.wikipedia.org/wiki/ "Several methods have been used to define the subtropical climate. In the Trewartha climate classification, a subtropical region should have at least eight months with a mean temperature of 10 °C (50.0 °F) or above. German climatologists Carl Troll and Karlheinz Paffen defined Warm temperate zones as plain and hilly lands having an average temperature of the coldest month between 2 °C (35.6 °F) and 13 °C (55.4 °F) in the Northern Hemisphere and between 6 °C (42.8 °F) and 13 °C (55.4 °F) in the Southern Hemisphere, excluding oceanic and continental climates. According to the Troll-Paffen climate classification, there generally exists one large subtropical zone named the warm-temperate subtropical zone,[4] which is subdivided into seven smaller areas.[5] According to the E. Neef climate classification, the subtropical zone is divided into two parts: Rainy winters of the west sides and Eastern subtropical climate.[6] According to the Wilhelm Lauer & Peter Frankenberg climate classification, the subtropical zone is divided into three parts: high-continental, continental, and maritime.[7] According to the Siegmund/Frankenberg climate classification, subtropical is one of six climate zones in the world.[8]" subtropical A temperate condition is an environmental condition in which an environmental system receives less solar irradiance than those with subpolar conditions, but greater than those with subtropical conditions. 2013-04-07T14:36:47Z SPIRE:Temperate tepid climate This class' definition is less satisfactory than the other latitudinal conditoins. temperate A temperate condition is an environmental condition in which an environmental system receives less solar irradiance than those with subpolar conditions, but greater than those with subtropical conditions. https://en.wikipedia.org/wiki/Temperate_climate tepid climate https://en.wikipedia.org/wiki/Temperate_climate A mediterranean condition is a subtropical condition in which hot dry summers and winters with moderate to high rainfall. 2013-04-07T14:36:47Z These regions are under the constant influence of the influence of large, usually marine, bodies of water and subtropical ridges. mediterranean A mediterranean condition is a subtropical condition in which hot dry summers and winters with moderate to high rainfall. https://en.wikipedia.org/wiki/Subtropics A mediterranean woodland ecosystem which is in its climactic successional state.

DOI:10.1641/0006-3568(2001)051[0933:TEOTWA]2.0.CO;2 URL:http://worldwildlife.org/biomes Ice which is formed from water. 2013-10-13T12:01:28Z LTER:262 ice Water ice 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. When speaking about ice on Earth, usually water ice is meant - the solid, crystalline form of water found in the atmosphere as snow crystals, hail, ice pellets, etc., and on the earth's surface in forms such as hoarfrost, rime, glaze, sea ice, glacier ice, ground ice, frazil, anchor ice, etc. This form of water is, strictly speaking, called ice Ih, the Roman numeral I distinguishing it from more than a dozen other phases and the letter h distinguishing it from the metastable cubic phase ice Ic. Ice Ih is the only one of the several known phases of water ice that is stable at commonly occurring temperatures and pressures. (Some of the other forms have very unusual properties, ice VII, for example, being stable only at pressures above 22 400 kg/cm^2, but then existing at temperatures up to about 100C.) It has an open structure with a specific gravity of 0.9166 which is slightly less than water; because the water molecules bond to their neighbors covalently only in four directions; it therefore floats on higher density water, where broken molecular bonds permit closer packing. All commonly occurring forms of ice are crystalline, although large single crystals are relatively rare except in glaciers. The ice crystal lattice possesses hexagonal symmetry that manifests itself in the gross forms of such single crystals as are sometimes found in snow. At an air pressure of one atmosphere, ice melts at 0 C by definition of the Celsius temperature scale. (Strictly speaking the equilibrium point among water, ice, and vapor occurs at +0.01C, the triple point.) On the other hand, ice does not invariably form in liquid water cooled below this temperature; it has a tendency to supercool, more so in the absence of ice nuclei. In permafrost regions, ice may occupy voids in soils and rocks and may develop in a variety of forms. Ice may be colourless to pale blue or greenish-blue. It may appear white due to included gas bubbles; in exposures, ground ice may also appear black. In nature ice is formed either by: (a) the freezing of water, (b) the condensation of atmospheric water vapour direct into ice crystals, (c) the compaction of snow with or without the motion of a glacier, or (d) the impregnation of porous snow masses with water which subsequently freeze. water ice Ice which is formed from water. https://en.wikipedia.org/wiki/Ice ice http://www.eionet.europa.eu/gemet/concept/4131 A depression caused by the collapse of a pingo.

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. ecozone 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. https://en.wikipedia.org/wiki/ecozone A material entity which 1) is spatially continuous, 2) is composed of material of comparable thickness, composition, and physical properties, and 3) is physically distinct from adjacent portions of environmental material. 2013-10-15T16:42:02Z layer A material entity which 1) is spatially continuous, 2) is composed of material of comparable thickness, composition, and physical properties, and 3) is physically distinct from adjacent portions of environmental material.

The adjacency of water has many consequences including the generation of microclimates and impacts on the biology. This class is intended to capture littoral zones that are associated with marine, freshwater, and any other aquatic environments. Note that there is no single definition of the extent of the "littoral zone", associated with any water body. Here, we use definitions that will be more familiar to marine biologists rather than military organisations, although the latter can be added on request. This class will likely be superceded by a CMECs compliant class. littoral zone An aquatic environment which is the part of a sea, lake, or river that is close to the shore. https://en.wikipedia.org/wiki/Littoral_zone 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. environmental area Formerly, this class was an experimental class and a subclass of "environmental feature".

Dacite consists mostly of plagioclase feldspar with biotite, hornblende, and pyroxene (augite and/or enstatite). It has quartz as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form transitions to the rhyolites. dacite Dacite is an igneous, volcanic rock.

Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of inundation and longer periods of saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do not usually support aquatic life such as fish. They typically have a high diversity of plant species, and may attract large numbers of birds, small mammals and insects including butterflies. wet meadow ecosystem A wet meadow is a type of wetland with soils that are saturated with water for part or all of the growing season. https://en.wikipedia.org/wiki/Wet_meadow Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland.

This class, along with benches, stools, and the like, can be grouped under "seating furniture" or similar. However, this is probably better as an inferred class using some sort of BFO:function in the subclass annotation. chair A piece of furniture is a movable object intended to support various human activities such as seating (e.g., chairs, stools and sofas) and sleeping (e.g., beds). The assumption is that furniture is manufactured, which is arguable. Further, according to Black's Law Dictionary (http://thelawdictionary.org/furniture/) many classes can be subclasses of 'piece of furntiure': "This term includes that which furnishes, or with which anything is furnished or supplied; whatever must be supplied to a house, a room, or the like, to make it habitable, convenient, or agreeable; goods, vessels, utensils, and other appendages necessary or convenient for housekeeping; whatever is added to the interior of a house or apartment, for use or convenience. Bell v. Holding, 27 Ind. 173.The term “furniture” embraces everything about the house that has been usually enjoyed there, including plate, linen, china, and pictures. 1 Endicott v. Endicott, 41N. J. Eq. 96, 3 Atl. 157.The word “furniture” made use of in the disposition of the law. or in the conventions or acts of persons, comprehends only such furniture as is intended for use and ornament of apartments, but not libraries which happen to be there, nor plate. Civ.Code La. art. 477." However, this would eventually be absurd and limit other groupings. Perhaps some sort of 'furnishing' BFO:function would be a better way to handle this. piece of furniture A piece of furniture is a movable object intended to support various human activities such as seating (e.g., chairs, stools and sofas) and sleeping (e.g., beds). https://en.wikipedia.org/wiki/Furniture A sofa is a bench which is partially or entirely upholstered, and often fitted with springs and tailored cushions. couch settee sofa A sofa is a bench which is partially or entirely upholstered, and often fitted with springs and tailored cushions. https://en.wikipedia.org/wiki/Couch A bench is a piece of furniture, on which several people may sit at the same time. bench A bench is a piece of furniture, on which several people may sit at the same time. https://en.wikipedia.org/wiki/Bench A mattress is a mass of material which is able to cushion and support a reclining body and is used as or on a bed. mattress A mattress is a mass of material which is able to cushion and support a reclining body and is used as or on a bed. https://en.wikipedia.org/wiki/Mattress A bed frame is a piece of furniture which is used to position a mattress and bed base and may include a means of supporting a canopy. bedstead bed frame A bed frame is a piece of furniture which is used to position a mattress and bed base and may include a means of supporting a canopy. https://en.wikipedia.org/wiki/Bed_frame A bed base is a piece of furniture which supports a mattress. bed foundation bed base A framed bed is a piece of furniture which is composed of a mattress supported by a bed base and held in place by a bed frame. framed bed A framed bed is a piece of furniture which is composed of a mattress supported by a bed base and held in place by a bed frame. https://en.wikipedia.org/wiki/Bed A cabinet is a roughly cuboidal piece of furniture which is used to store miscellaneous items in compartments accessible through doors or drawers. cabinet A cabinet is a roughly cuboidal piece of furniture which is used to store miscellaneous items in compartments accessible through doors or drawers. https://en.wikipedia.org/wiki/Cabinetry A cupboard is a cabinet which is used indoors to store household objects such as food, crockery, textiles and liquor, and to protect them from dust and dirt closet cupboard A cupboard is a cabinet which is used indoors to store household objects such as food, crockery, textiles and liquor, and to protect them from dust and dirt https://en.wikipedia.org/wiki/Cupboard A clock is an instrument which may indicate, keep, and/or co-ordinate time. timepiece clock A clock is an instrument which may indicate, keep, and/or co-ordinate time. https://en.wikipedia.org/wiki/Clock A pressure lamp is a portable paraffin or oil lamp in which fuel is forced up into the mantle or burner by air pressure in the reservoir, which can be increased by pumping with a plunger.

Minor planets can be dwarf planets, asteroids, trojans, centaurs, Kuiper belt objects, and other trans-Neptunian objects. This definition is in need of revision - it relies on negation and seems to straddle class and instance level. The definitional space here is contested and quite inhomogeneous. "Before 2006, the IAU had officially used the term minor planet. During its 2006 meeting, the IAU reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSB). Objects are called dwarf planets if their self-gravity is sufficient to achieve hydrostatic equilibrium and form an ellipsoidal shape. All other minor planets and comets are called small Solar System bodies. The IAU stated that the term minor planet may still be used, but the term small Solar System body will be preferred. However, for purposes of numbering and naming, the traditional distinction between minor planet and comet is still used." minor planet A minor planet is an astronomical object in direct orbit around the Sun that is neither a planet nor exclusively classified as a comet.

Also note that some astronomical body parts (ABPs) may have fiat boundaries: if there's strong debate about where an ABP begins or ends (over and above fuzzy boundaries), with different official classifications setting different thresholds or limits, axiomatise the class with fiat boundaries of the appropriate dimension. Note that material entities may have immaterial entities (e.g. sites) as parts. This class includes material parts of astronomical bodies. Immaterial parts, such as magnetospheres, are represented as sites under the influence of magnetic fields.Please post countercases in the ENVO tracker for revision of this hierarchy if needed. Material parts of astronomical bodies generally have boundaries formed by discontinuities in qualities, composition, or other physical characterisitcs. These boundaries are sometimes sharp, and sometimes diffuse, with different classification systems and communities declaring varying thresholds (e.g. for where a shoreline, forest, or other entity begins and ends). However, some boundaries are declared by fiat - that is, by arbitrary human convention or decree - particularly by regulatory or other authorities and communities of practice. The classes in this hierarchy attempt to offer generalisable definitions that allow multiple classfiication systems to map to and interoperate through. If desired, we can create classes that declare thresholds used by a given authority or community under the more generic ones, annotated with source information. astronomical body part An environmental material which is in a solid state.

In such an inversion, the surface must have a temperature below freezing, while the temperature of the atmosphere where the precipitation forms is above freezing. Alternately, if the temperature of the ground surface and glazed objects is typically near or below freezing (0C or 32F), it is necessary that the water drops be supercooled before striking. Freezing rain can sometimes occur on surfaces exposed to the air (such as tree limbs) with air temperatures slightly above freezing in strong winds. Local evaporational cooling may result in freezing. Freezing rain frequently occurs, therefore, as a transient condition between the occurrence of rain and ice pellets (sleet). When encountered by an aircraft in flight, freezing rain can cause a dangerous accretion of clear icing.

Freezing rain can sometimes occur on surfaces exposed to the air (such as tree limbs) with air temperatures slightly above freezing in strong winds. Local evaporational cooling may result in freezing. Freezing rain frequently occurs, therefore, as a transient condition between the occurrence of rain and ice pellets (sleet). When encountered by an aircraft in flight, freezing rain can cause a dangerous accretion of clear icing. In aviation weather observations, this hydrometeor is encoded ZR by NOAA. A process during which a sudden flow of electricity occurs, often accompanied by a visible release of photons, between two electrically charged objects due to contact, an electrical short, or dielectric breakdown. This should probably be moved to an ontology of physical processes when one is created, and be imported back into ENVO. electrostatic discharge process A process during which a sudden flow of electricity occurs, often accompanied by a visible release of photons, between two electrically charged objects due to contact, an electrical short, or dielectric breakdown. https://en.wikipedia.org/wiki/Electrostatic_discharge A sudden electrostatic discharge which occurs during an electrical storm as differentially charged atmospheric entities equalise their charge. lightning atmospheric lightning A sudden electrostatic discharge which occurs during an electrical storm as differentially charged atmospheric entities equalise their charge. https://en.wikipedia.org/wiki/Lightning A lightning process during which electrostatic discharge occurs between at least two clouds.

Earlier definitions also included a condition of low temperatures, on the order of -7C (20F) or lower, or -12C (10F) or lower (severe blizzard). The name originated in the United States but it is also used in other countries. In the Antarctic the name is given to violent autumnal winds off the ice cap. In southeastern France, the cold north wind with snow is termed blizzard (see also boulbie). Similar storms in Russian Asia are the buran and purga. In popular usage in the United States and in England, the term is often used for any heavy snowstorm accompanied by strong winds. To qualify a snowstorm as a blizzard, some sources require the windspeed to be at least 56 km/h and the duration of the storm to be at least three hours. We set no such hard boundaries in this definition, as this should be done with reference to local standards. blizzard A blizzard is a severe snowstorm during which snowfall is transported by strong winds, sustained for several hours. https://en.wikipedia.org/wiki/Blizzard To qualify a snowstorm as a blizzard, some sources require the windspeed to be at least 56 km/h and the duration of the storm to be at least three hours.

Expand the sites of occurrence listed as axioms as new terms emerge. aquatic farming In 1988, the FAO introduced a definition of aquaculture which reduces its confusion with capture fisheries: Aquaculture is the farming of aquatic organisms, including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated. For statistical purposes, aquatic organisms which are harvested by an individual or corporate body which has owned them throughout their rearing period contribute to aquaculture, while aquatic organisms which are exploitable by the public as a common property resources, with or without appropriate licences, are the harvest of fisheries. aquaculture process A process during which humans rear animals or plants in bodies of water for harvest and consumption. http://www.fao.org/docrep/003/x6941e/x6941e04.htm#bm04 An archeological site which contains holes humans had dug in the ground, or their remnants, for the purpose of storing and distributing food, drink, and both functional or ritualistic implements during communal eating and drinking.

Magentospheres are generated by the motion of active hot iron and nickle or metallic planetary cores or by the interactions of plasma in stars.. The magnetic field near the surface of many astronomical bodies resembles that of a dipole. The field lines farther away from the surface can be significantly distorted by the flow of electrically conducting plasma emitted from a nearby star. The structure and behaviour of magnetospheres depend on numerous variables, including the type of astronomical body which generates it, the period of the object's spin, the properties of the axis about which the object spins, the axis of the magnetic dipole, and the magnitude and direction of the flow of stellar wind. magnetosphere A site in which charged particles are influenced by an astronomical body's magnetic field. https://en.wikipedia.org/wiki/Magnetosphere Magentospheres are generated by the motion of active hot iron and nickle or metallic planetary cores or by the interactions of plasma in stars..

CMECS provides the following notes: "Commonly found on intertidal mud flats along the shores of estuaries. Tidal mangrove shrublands may include immature stands or stunted mature trees that indicate a harsh growing environment. Areas characterized by tall mangroves (> 6 meters) are placed in the Tidal Mangrove Forest Biotic Group. Where tidal amplitude is relatively low, the vegetation forms narrow bands along the coastal plains, and it rarely penetrates inland more than several kilometers along rivers. Where tidal amplitude is greater, mangroves extend further inland along river courses, forming extensive stands in the major river deltas. Also, mangrove cays may occur within the lagoon complex of barrier reefs. The list of biotic communities for this group is long: a few examples are provided below, and the complete list is available in Appendix F" tidal mangrove shrubland An ecosystem which 1) typically has monthly average temperatures below 10 degrees Celsius 2) has a low evapotranspiration ratio 3) is dominated by treeless terrain, covered by communities of low-growing vegetation such as dwarf shrubs, sedges and grasses, mosses, and lichens, 4) contains areas of soil underlain by permafrost with a thin active layer and 5) occurs in both polar and alpine regions (i.e., both high latitudes and high altitudes), and 5) does not have permanent snow or ice cover.

Altostratus clouds do not show halo phenomena when scattering visible range stellar radiation. Altostratus clouds have parts thin enough to reveal the local star at least vaguely, as through ground glass or frosted glass. Altostratus may produce rain, snow or ice pellets. Altostratus is usually found in the middle level, but it often extends higher. Altostratus is generally a layer of great horizontal extent (several tens or hundreds of kilometres) and fairly considerable vertical extent (several hundreds or thousands of metres). In the most complete case, three superposed parts can be distinguished: (a) An upper part, composed wholly or mainly of ice crystals, (b) A middle part, composed of a mixture of ice crystals, snow crystals or snowflakes and supercooled water droplets, (c) A lower part, composed wholly or mainly of ordinary or supercooled water droplets or drops. Sometimes the cloud may consist of only two parts, either: 1) An upper part like (a) above and a lower part like (c) or, 2) An upper part like (b) and a lower part like (c). Less frequently, the entire cloud may also be like (a) or like (b) alone. altostratus cloud A cloud which 1) occurs in the form of a striated, fibrous, or uniform sheet or layer, 2) is composed of water droplets and ice crystals, 3) is located in the middle level of the atmosphere (middle étage).

Nimbostratus generally covers a wide area and is of great vertical extent. Nimbostratus is diffused by more or less continuously falling rain or snow or ice pellets, which in most cases reaches the ground. Sometimes nimbostratus clouds have the appearance of being illuminated from the inside. Nimbostratus is almost always found in the middle level, but it usually extends into the other two levels. Nimbostratus is thick enough throughout to blot out the local star. nimbostratus cloud A cloud which 1) occurs in the form of a layer, 2) is composed of water droplets (sometimes supercooled) and raindrops, or snow crystals and snowflakes, or of a mixture of these liquid and solid particles, 3) is located in the middle level of the atmosphere (middle étage).
