Weight sensor
Weather station

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.

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).

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.

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.

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.
