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. rock 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. regolith LTER:535 SPIRE:Soil SWEETRealm:Soil https://en.wikipedia.org/wiki/Soil '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."

It's possible that this will become an inferred class in the future. The United Nations' International Standard Industrial Classification should be referred to when expanding this branch. ISIC can also be used to identify processes. See http://unstats.un.org/unsd/cr/registry/regcst.asp?Cl=27&Lg=1. industrial building A dairy is a building in which animal milk is harvested and, optionally, processed for human consumption. https://en.wikipedia.org/wiki/Dairy '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 dairy A food processing building is a building in which materials that contain or consist of essential body nutrients - such as carbohydrates, fats, proteins, vitamins, or minerals - and may be ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life are converted alternative forms. The semantics of food are being handled by FOODON http://purl.obolibrary.org/obo/foodon.owl food processing building A bakery is a building in which raw flour-based food is baked in an oven to produce food products such as bread, cakes, pastries, and pies.

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. environmental material A layer of some material entity which is adjacent to one or more of its external boundaries and directly interacts with its immediate surroundings. EcoLexicon:surface http://sweetontology.net/reprSpaceGeometry/Surface https://en.wikipedia.org/wiki/Surface 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. surface layer A facility in which animals are confined within enclosures and displayed to the public, and in which they may also be bred. zoo zoological park zoological garden Anthropogenic material in or on which organisms may live. anthropogenic environmental material This is quite odd and it probably should be obsoleted.

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. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. ocean biome Particulate material is an environmental material which is composed of microscopic portions of solid or liquid material suspended in another environmental material. envoAtmo envoPolar particulate matter Environmental material derived from living organisms and composed primarily of one or more biomacromolecules.

Mangrove plants are able to withstand high levels of salinity as well as regions of anoxia and frequent tidal inundation. Mangrove biomes often occur near tropical and sub-tropical estuaries and depositional marine coastal environments where fine sediments (often with high organic content) collect in areas protected from high energy wave action. LTER:322 wwfBiome Preliminary definition. Depending on whether mangrove trees or shrubs are present, this class could be a child of shrubland biome or woodland biome. Consider creating the appropriate classes. mangrove biome An anthropogenic terrestrial biome is a terrestrial biome which has community structures determined by human activity. anthrome human biome Preliminary definition. anthropogenic terrestrial biome A cropland ecosystem in which dominant ecological communities are maintained in a stable state - mimicking a climax community - by human intervention. cropland biome A village biome is an anthropogenic terrestrial biome which contains settlements such as villages, towns, and/or small cities and which is primarily used for agricultural activity.

EcoLexicon:environment environment 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. environmental system A layer is a quantity of some material which is spatially continuous, has comparable thickness, and usually covers some surface. envoPolar Preliminary definition. layer A marine environment and enviroment which is determined by a marine water body. envoPolar marine environment A planetary surface is a surface layer where the solid or liquid material of a planet comes into contact with an atmosphere or outer space. a useful class: this can be used to define sub-terrestrial and sub-marine entities planetary surface A field used for the cultivation of corn or related crop plants.

The provisioning of a dwelling-place can perhaps be modelled as a role. house A human house is a house which provides a dwelling-place for humans. human house A building part is a construction which is part of a building. Not recommended for annotation. This class is likely to be made into an inferred class as its subclasses are distributed among more meaningful superclasses (i.e. ceiling is_a surface layer). See for example, "building floor". The boundaries between building parts may be bona fide or fiat. building part A bathroom is a room which contains a washbasin or other fixture, such as a shower or bath, used for bathing by humans. bathing room bathroom A building part which is separated from other building parts by one or more interior walls and, optionally, outdoor areas by one or more exterior walls. room A constructed barrier is a freestanding wall, berm, or fence built to limit movement of entities across a boundary. barrier constructed barrier Glass is an amorphous (non-crystalline) solid which is often transparent. This class refers to all forms of glass. For the familiar form present in window panes and drinking glasses, consider silica-based glass. glass Silica-based glass is a glass composed primarily of silicon dioxide, the primary constituent of sand. glass Silica-based glasses are the most common manufactured variety of glass. silica-based glass A building floor is a surface layer which is part of a building and used for walking. To be more precise, a subfloor and a floor covering may be specified. Please request these classes and propose definitions if they are needed. building floor A factory (previously manufactory) or manufacturing plant is an industrial site, usually consisting of buildings and machinery, or more commonly a complex having several buildings, where workers manufacture goods or operate machines processing one product into another. manufactory manufacturing plant factory A table is a form of furniture with a flat horizontal upper surface used to support objects, for storage, show, and/or manipulation. table A desk is a table which is intended for information-manipulation tasks, including writing and use of interactive electronics. The intentional nature of this definition is problematic, but the restricted range of activities visited upon a desk is of interest. desk 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 motor vehicle is a vehicle which is propelled by an engine or motor and that does not operate on rails.
