Weight sensor Weight sensor Weather station A sensor o system that measure weather conditions. has feature of interest Relation between a measurement and the feature of interest being measured. Measurement 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. 1 Building 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). Feature 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. 1 Unit of measure 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).

Farm A plot of land used for the scope of farming which can contain buildings and parcels. host Relation between a platform and the systems it hosts. is measured by device makes measurement 1 within Exists if the subject SpatialObject is spatially within the object SpatialObject. DE-9IM: T*F**F*** Property An aspect of an entity that can be observable by a sensor. 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. has description A relationship providing a description of an entity (e.g., device) Feature of interest Humidity Humidiy A saref:Property related to some measurements that are characterized by a certain value that is measured in a humidity unit https://saref.etsi.org/saref4agri/ 2019-04-30 SAREF4AGRI is an extension of SAREF for the agriculture and food domain. SAREF4AGRI is specified and published by ETSI in the TS 103 410-6 associated to this ontology file. The list of use cases, standards and requirements that guided the creation of SAREF4AGRI are described in the associated ETSI TR 103 511. This ontology extends the SAREF ontology for the Agricultural domain. This work has been developed in the context of the STF 534 (https://portal.etsi.org/STF/STFs/STFHomePages/STF534.aspx), which was established with the goal to create three SAREF extensions, one of them for the Agricultural domain. 2019-04-15 s4agri 2020-06-05 v1.1.2 SAREF4AGRI: an extension of SAREF for the agriculture and food domain controls property 1 ID ID Animal Group A collection of one or multiple animals. Actuator Deployment The scenario, including temporal and spatial information, in which the systems and devices are installed. Deployment Animal 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. Point Uniquely identified by lat/long/alt. i.e. spaciallyIntersects(P1, P2) :- lat(P1, LAT), long(P1, LONG), alt(P1, ALT), lat(P2, LAT), long(P2, LONG), alt(P2, ALT). sameThing(P1, P2) :- type(P1, Point), type(P2, Point), spaciallyIntersects(P1, P2). A point, typically described using a coordinate system relative to Earth, such as WGS84. latitude The WGS84 latitude of a SpatialThing (decimal degrees). acts upon A relationship between a command and a state Soil Upper layer of the earth in which plants grow. Intake The amount of food or other substance taken into the body of an animal or into the soil. Command 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. 1 Milking sensor Milking sensor is located in A relation to express the physical location of a saref4agri entity (e.g., an animal) Watering valve Watering valve Platform Platform Temporal entity A temporal interval or instant. contains Exists if the subject SpatialObject spatially contains the object SpatialObject.

Watering gun An actuator to irrigate an space. 1 is deployed at space is deployed at space Relation to indicate the geographical componet of a deployment. has function A relationship identifying the type of function of a device 1 Function 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.

Task 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. Person Organization Building space An entity used to define the physical spaces of the building. A building space contains devices or building objects. has name A relation to express the name of an entity (e.g.,animal). Geometry 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. System System is a unit of abstraction for pieces of infrastructure that implement Procedures. A System may have components, its subsystems, which are other Systems.

Deployment has value Plant growth stage The level or stage of growth of the plant. 1 Crop A collection of cultivated plants that is grown on a large scale commercially, especially a cereal, fruit, or vegetable. measurement made by Relation between a measurement and the device that made it. Precipitation The amount of water falling in the soil by natural process (e.g. rain). location The relation between something and the point, or other geometrical thing in space, where it is. For example, the realtionship between a radio tower and a Point with a given lat and long. Or a relationship between a park and its outline as a closed arc of points, or a road and its location as a arc (a sequence of points). Clearly in practice there will be limit to the accuracy of any such statement, but one would expect an accuracy appropriate for the size of the object and uses such as mapping . manages farm manages farm Temperature 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) State 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. has state has plant date A relation to express the day the crop is planted. has deployment has deployment period has deployment period Relation to indicate the temporal duration or period of a deployment.
