Farm holding A class to decsribe a saref4agri farm holding as subcass of an org:Organization 1 is contained in is contained in s4agri 2019-04-15 SAREF4AGRI: an extension of SAREF for the agriculture and food domain https://saref.etsi.org/saref4agri/ v1.1.2 2019-04-30 2020-06-05 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. 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.

DE-9IM: T*****FF* member decibel-milliwatts Thermometer Thermometer 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. is accomplished by A relationship indentifying the task accomplished by a certain entity (e.g., a device) has member A relation to represent the members of an AnimalGroup. Humidity Humidiy A saref:Property related to some measurements that are characterized by a certain value that is measured in a humidity unit 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 . is property of Relation between a property and a feature of interest in which such property appears. has state receives A relation to represent the intake/consumption of certain substances in a Crop. Irrigation water The amount of water falling in the soil by irrigation methods. Soil temperature The degree or intensity of heat present in the soil.

Animal Group A collection of one or multiple animals. Watering valve Watering valve is command of A relationship between a command and a function. 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). The unit of measure is a standard for measurement of a quantity, such as a Property.

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. measurement made by Relation between a measurement and the device that made it. 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). has command A relationship between an entity (such as a function) and a command Milking sensor Milking sensor 1 accomplishes A relationship between a certain entity (e.g., a device) and the task it accomplishes makes measurement Time interval A temporal entity with an extent or duration Platform 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) Actuator 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) SpatialObject The class spatial-object represents everything that can have a spatial representation.

Watering system Watering system Intake The amount of food or other substance taken into the body of an animal or into the soil. has taxon rank deployed system Relation between a deployment and the system deployed. 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. Pluviometer A sensor that measures the rain fall. Yield The produced amount of food for animals or of agricultural products. has plant date A relation to express the day the crop is planted. 1 Watering gun An actuator to irrigate an space. 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.

Agent deployed on platform Relation between a deployment and the platform(s) involved in the deployment. longitude The WGS84 longitude of a SpatialThing (decimal degrees). is location of is location of relates to measurement ID ID 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. 1 has subsystem 1 has birth date A relation to express the birth date of an animal. in deployment Relation between a platform and the deployment(s) that takes place in the platform. 1 Parcel An area of land, which might be used for grazing animals or planting crops. The parcel is defined as an undividable logical area of land which contains homogeneous items. is measured by device controls property Time A saref:Property that allows to specify the time concept in terms of instants or intervals according to the imported W3C Time ontology. generates A relation to represent the yield generated by a Crop. has feature of interest Relation between a measurement and the feature of interest being measured. Soil moisture The amount of water or humidity contained in the soil. contains contains has name A relation to express the name of an entity (e.g.,animal). latitude The WGS84 latitude of a SpatialThing (decimal degrees). 1 acts upon A relationship between a command and a state millibar Movement activity sensor Movement activity sensor Air temperature The degree or intensity of heat present in the air. 1 degree Celsius is feature of interest of Relation betwwen a feature of interest and the measurments that are about it. 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. host Relation between a platform and the systems it hosts.
