comment: "There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague."

comment: The definitions of forest can vary greatly, and different classes will be needed to support the major categories. Tree cover alone is not enough to distinguish between forests and plantations. The international definition proposed by the 2010 FAO Forestry Resource Assessment: "land spanning more than 0.5 ha with trees higher than 5 metres and canopy cover of more than 10 percent, or trees able to reach these thresholds in situ . It does not include land that is predominantly under agricultural or urban land use." - FAO. 2010. Global forest resources assessment 2010, Main report, FAO Forestry Paper 163. Rome.

comment: '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."

has exact synonym: feces material
comment: ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.
comment: This is distinct from classes such as http://purl.obolibrary.org/obo/UBERON_0001988 in that it refers to the environmental material composed primarily of feces rather than 'just' feces.

has db xref: https://en.wikipedia.org/wiki/Dairy
comment: 'Terminology differs between countries. For example, in the United States, the entire dairy farm is commonly called a "dairy." The building or farm area where milk is harvested from the cow is often called a "milking parlor" or "parlor." The farm area where milk is stored in bulk tanks is known as the farm's "milk house." Milk is then hauled (usually by truck) to a "dairy plant," also referred to as a "dairy", where raw milk is further processed and prepared for commercial sale of dairy products. In New Zealand, farm areas for milk harvesting are also called "milking parlours", and are historically known as "milking sheds."' https://en.wikipedia.org/wiki/Dairy

comment: 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.

surface layer

comment: 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.

Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 metres (9,800 ft) deep.

Mangrove plants are able to withstand high levels of salinity as well as regions of anoxia and frequent tidal inundation.

IAO_0000412: envo.owl
comment: 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.

IAO_0000412: envo.owl
comment: Fairgrounds, or parts thereof, may be constructed (e.g. concreted over) or be natural (e.g. clearings or heaths), thus land use is the key differentia.

agricultural fairground

IAO_0000115: A fairground which is used to exhibit agricultural technology, livestock, and farm-related activity.
IAO_0000412: envo.owl

IAO_0000115: A plumbing fixture within which a human or other animal may bathe under a spray of water.
IAO_0000412: envo.owl
comment: Indoors, there is a drain in the floor. Most showers have temperature, spray pressure and adjustable showerhead nozzle.

IAO_0000412: envo.owl
comment: The definitions of forest can vary greatly, and different classes will be needed to support the major categories. Tree cover alone is not enough to distinguish between forests and plantations. The international definition proposed by the 2010 FAO Forestry Resource Assessment: "land spanning more than 0.5 ha with trees higher than 5 metres and canopy cover of more than 10 percent, or trees able to reach these thresholds in situ . It does not include land that is predominantly under agricultural or urban land use." - FAO. 2010. Global forest resources assessment 2010, Main report, FAO Forestry Paper 163. Rome.

We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.

has db xref: https://en.wikipedia.org/wiki/Animal_feed
comment: Most animal feed is from plants but some is of animal origin. Fodder refers particularly to food given to the animals (including plants cut and carried to them), rather than that which they forage for themselves. It includes hay, straw, silage, compressed and pelleted feeds, oils and mixed rations, and also sprouted grains and legumes.

subclass of: single-species collection of organisms
IAO_0000114: IAO_0000125
IAO_0000115: A collection of organisms, all of the same species, that live in the same place.
IAO_0000119: ISBN:0878932739
IAO_0000412: envo.owl
comment: 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.
