SAREF extension for water

This class represents the top-level feature type. This class is equivalent to GFI_Feature defined in ISO 19156:2011, and it is superclass of all feature types.

The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types.

The day of week.

A temporal entity with zero extent or duration

A temporal entity with an extent or duration.

Time extent; duration of a time interval separate from its particular start position

A temporal interval or instant.

A device responsible for moving or controlling a mechanism or system.

A tangible object designed to accomplish a particular task in households, common public buildings or offices. In order to accomplish this task, the device performs one or more functions. For example, a washing machine is designed to wash (task) and to accomplish this task it performs a start and stop function. Devices can be structured in categories (subclasses) that reflect the different domain in which a device is used, e.g., smart appliances domain (subclass FunctionRelated) vs. building domain (subclass BuildingRelated) vs. smart grid domain (subclass EnergyRelated). New categories can be defined,if needed, to reflect other differences, for example different points of view, such as the point of view of the device's user vs. the point of view of the device's manufacturer. We propose a list of devices that are relevant for the purpose of SAREF, but this list can be extended.

Represents the measured value made over a property. It is also linked to the unit of measure in which the value is expressed and the timestamp of the measurement.

A device built to accurately detect and display a quantity in a form readable by a human being. Further, a device of category saref:Meter that performs a saref:MeteringFunction.

An aspect of an entity that can be observable by a sensor.

A device that detects and responds to events or changes in the physical environment such as light, motion, or temperature changes. A device that has category saref:Sensor and performs a saref:SensingFunction.

The unit of measure is a standard for measurement of a quantity, such as a Property. For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called "watt". Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of the Smart Appliances ontology, but this list can be extended.

An agent making an action in the context of a city. An agent could be a person, software, etc.

A Key Performance Indicator (KPI) is a type of performance measurement. KPIs evaluate the success of an organization or of a particular activity in which it engages. (Definition taken from FIWARE)

A Key Performance Indicator assessment represents the assessment of a KPI calculated by a given agent in a given time.

An acceptability property is a property of water that is related to its acceptability.

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials.

A bacterial property is a property of water that is related to bacteria.

A channel is a passage of water flowing in an open conduit (i.e., subject to atmospheric pressure).

A chemical property is a property of water that is related to chemical components.

A consumption-based tariff is a tariff that is based on consumption.

A water distribution system is an infrastructure to carry potable water from a centralized treatment plant or wells to water consumers in order to adequately deliver water to satisfy residential, commercial, industrial and fire fighting requirements.

Class to group those properties related to the environment.

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.

A fire hydrant is a fitting in a street or other public place with a nozzle by which a fire hose may be attached to a water main.

A gauging station is an infrastructure to monitor and test terrestrial bodies of water.

A glacier is a persistent body of dense ice that is constantly moving under its own weight.

A hydroelectric power plant is an infrastructure to generate electricity by conversion of the energy of running water.

An intake is an installation for obtaining water from a source of supply (river, lake, reservoir, and so on).

A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs.

A lake is an area filled with water, localized in a basin, surrounded by land, apart from any river or other outlet that serves to feed or drain the lake.

A main is a passage of water to flow through.

A maintenance hole is an enclosure that facilitates human access to and working space for equipment.

A microbial property is a property of water that is related to microbes.

A monitoring infrastructure is an infrastructure to monitor water.

An ocean is a large body of salt water.

A pipe is a passage of water flowing in a closed conduit (i.e., not subject to atmospheric pressure).

A pit is a well or hole sunk in the ground to procure, store or drain water.

A pump is a device for moving water by mechanical action.

A reservoir is an enlarged natural or artificial lake, pond or impoundment created using a dam or lock to store water.

A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.

A sea is a body of salt water partly or fully enclosed by land.

A sink asset is a water asset where water sinks.

A source asset is a water asset that is a natural source of water.

A storage asset is a water asset used to store water.

An storage infrastructure is an infrastructure to storage both potable water for consumption, and non potable water for use in agriculture.

A tank is a container for storing water.

A tariff is a schedule of rates or charges of a business or a public utility. Tariffs can be based on time, thresholds or consumption; however, combined tariffs may also exist that mix more than one of these types.

A threshold-based tariff is a tariff that is based on a threshold.

A time-based tariff is a tariff that is based on time.

A transport asset is a water asset used to enable and support the transport and distribution of water.

A treatment plant is an infrastructure to improve the quality of water to make it more acceptable for a specific end-use.

A valve is a device designed to control water flow, pressure or volume.

A vent is the part of a system that allows air to enter a plumbing system to maintain proper air pressure and sewer gases to escape to the outside.

This class is used to define a particular quantity or body of water.

A water asset is a physical entity used in the process of transporting, treating, storing and distributing water.
