SAREF4AGRI: an extension of SAREF for the agriculture and food domain

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 class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry.

A point, typically described using a coordinate system relative to Earth, such as WGS84.

A temporal entity with zero extent or duration

A temporal entity with an extent or duration

A temporal interval or instant.

A Platform is an entity that hosts other entities, particularly Sensors, Actuators, Samplers, and other Platforms (definition taken from http://www.w3.org/ns/sosa/Platform)

System is a unit of abstraction for pieces of infrastructure that implement Procedures. A System may have components, its subsystems, which are other Systems. (Definition taken from http://www.w3.org/ns/ssn/System)

A directive that a device must support to perform a certain function. A command may act upon a state, but does not necessarily act upon a state. For example, the ON command acts upon the ON/OFF state, but the GET command does not act upon any state, it simply gives a directive to retrieve a certain value. We propose here a list of commands that are relevant for the purpose of SAREF, but this list can be extended.

The functionality necessary to accomplish the task for which a Device is designed. A device can be designed to perform more than one function. Functions can be structured in categories (subclasses) that reflect different points of view, for example, considering the specific application area for which a function can be used (e.g., light, temperature, motion, heat, power, etc.), or the capability that a function can support (e.g., receive, reply, notify, etc.), and so forth.

A saref:Property related to some measurements that are characterized by a certain value that is measured in a humidity unit

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.

Anything that can be sensed, measured or controlled in households, common public buildings or offices. We propose here a list of properties that are relevant for the purpose of SAREF, but this list can be extended.

The state in which a device can be found, e.g, ON/OFF/STANDBY, or ONLINE/OFFLINE. We propose here a list of states that are relevant for the purpose of SAREF, but this list can be extended.

The goal for which a device is designed (from a user perspective). For example, a washing machine is designed for the task of washing. We propose here a list of tasks that are relevant for the purpose of SAREF, but this list can be extended.

A saref:Property related to some measurements that are characterized by a certain value that is measured in a temperature unit (degree_Celsius, degree_Fahrenheit, or degree_kelvin)

A saref:Property that allows to specify the time concept in terms of instants or intervals according to the imported W3C Time ontology.

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 SAREF, but this list can be extended, also using some other ontologies rather than the Ontology of units of Measure (OM).

An individual and identifiable living organism that feeds on organic matter, typically having specialized sense organs and nervous system and able to respond rapidly to stimuli.

A collection of one or multiple animals.

A building represents a structure that provides shelter for its occupants or contents and stands in one place. The building is also used to provide a basic element within the spatial structure hierarchy for the components of a building project (together with site, storey, and space).

An entity used to define the physical spaces of the building. A building space contains devices or building objects.

A collection of cultivated plants that is grown on a large scale commercially, especially a cereal, fruit, or vegetable.

The scenario, including temporal and spatial information, in which the systems and devices are installed.

Eating activity sensor

A plot of land used for the scope of farming which can contain buildings and parcels.
