<p>The <ahref="#s4agri:Animal">s4agri:Animal</a> class describes an animal that can be classified in SAREF4AGRI reusing the TAXRANK taxonomy vocabulary (<ahref="http://purl.obolibrary.org/obo/taxrank.owl#">http://purl.obolibrary.org/obo/taxrank.owl#</a>). Besides the reuse of the TAXRANK taxonomy vocabulary, an animal is furthermore defined in SAREF4AGRI in order to have a birth and death date. An animal also has a unique identifier and can be part of one or more <ahref="#s4agri:AnimalGroup">s4agri:AnimalGroup</a> that are used to conduct experiments and observations on the livestock. Note that animals can be also specialized using subclasses, as is shown in the example in clause 4.3.1 with the ex:LactatingCow class that was created as a subclass of <ahref="#s4agri:Animal">s4agri:Animal</a>. Animals and animal groups are related to measurements via the <ahref="https://saref.etsi.org/core/FeatureOfinterest">saref:FeatureOfinterest</a> concept of SAREF (see clause 4.2.3). </p>
<p>The <ahref="#s4agri:Soil">s4agri:Soil</a> class represents the upper layer of the earth in which plants grow. The <ahref="#s4agri:Crop">s4agri:Crop</a> class describes a collection of homogeneous plant species that is grown on a large scale commercially (especially a cereal, fruit, or vegetable) and is planted on a single location. A <ahref="#s4agri:Crop">s4agri:Crop</a> is grown on some <ahref="#s4agri:Parcel">s4agri:Parcel</a>, which is an area of land, defined in SAREF4AGRI as subclass of the geosp:Feature (see clause 4.2.6). Moreover, <ahref="#s4agri:Crop">s4agri:Crop</a> is related to measurements via <ahref="https://saref.etsi.org/core/FeatureOfInterest">saref:FeatureOfInterest</a> (see clause 4.2.3</a>).</p>

<h3>Topology</h3>
<p>SAREF4AGRI adopts the same topology modelling pattern that is adopted in the SAREF4CITY extension <ahref="#[i.3]">[i.3]</a>, where existing standard ontologies have been reused for this purpose. As shown in <ahref="#Figure_7">Figure 7</a>, for representing spatial objects in SAREF4AGRI, the geosp:SpatialObject class from GeoSPARQL has been reused along with its subclasses geosp:Feature, geosp:Geometry and the properties geosp:sfContains, geosp:sfWithin and geosp:hasGeometry. In addition, the class geo:Point and the property geo:location have been reused from the "WGS84 Geo Positioning vocabulary" (which is the W3C de-facto standard for geographical information) in order to be able to indicate that something is located at certain coordinates. </p>

<p>A <ahref="#s4agri:Farm">s4agri:Farm</a> can contain one or more <ahref="https://saref.etsi.org/saref4bldg/Building">s4bldg:Building</a> and <ahref="#s4agri:Parcel">s4agri:Parcel</a> (via the geosp:sfContains relation). Note that these types of feature are used in the present document as examples, but more feature types (and building types) can be added as needed. Moreover, a <ahref="https://saref.etsi.org/saref4bldg/Building">s4bldg:Building</a> can be further decomposed in one or more <ahref="https://saref.etsi.org/saref4bldg/BuildingSpaces">s4bldg:BuildingSpaces</a> (once again via the geosp:sfContains relation). As subclasses of geosp:Feature, all the classes mentioned above inherit the possibility to have a physical geometric description using geosp:Geometry, if needed (e.g. especially relevant for <ahref="#s4agri:Parcel">s4agri:Parcel</a>). As subclasses of geosp:SpatialObject, all the classes mentioned above also inherit the possibility to use the geo:location property to indicate that something is located at certain coordinates (e.g. especially relevant for <ahref="#s4agri:Bulding">s4agri:Bulding</a>). </p>
