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. SAREF extension for Agriculture s4agri https://w3id.org/def/saref4agri# 0.1 The WGS84 altitude of a SpatialThing (decimal meters above the local reference ellipsoid). altitude The WGS84 latitude of a SpatialThing (decimal degrees). latitude The WGS84 longitude of a SpatialThing (decimal degrees). longitude A spatial representation for a given feature. has geometry Exists if the subject SpatialObject spatially contains the object SpatialObject.

Geometry Matthew Perry OGC GeoSPARQL 1.0 Standard Working Group 2011-06-16 The class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry. The class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry. SpatialObject The class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry. SpatialObject 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. Point point A temporal entity with zero extent or duration Instant A temporal entity with an extent or duration Time interval A temporal interval or instant. Temporal entity Communication Communication role Deployment WARNING! This class might be moved to the SAREF ontology Feature of interest Network Node Platform System Actuator 1 1 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. Command Device 1 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. Function A saref:Property related to some measurements that are characterized by a certain value that is measured in a humidity unit Humidity 1 1 1 1 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. Measurement 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. Property Property Sensor 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. State 1 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. Task 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) Temperature A saref:Property that allows to specify the time concept in terms of instants or intervals according to the imported W3C Time ontology. Time 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.

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). Unit of measure Unit of measure 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 . location
