As it can be observed in Figure 3, the modelling of measurements in the SAREF4WATR ontology mostly relies on the measurement model proposed in SAREF.
-SAREF allows to define the temporal extent of a measurement by defining the timestamp for it (using the saref:hasTimestamp property). However, the SAREF4WATR extension also required to be able to define the temporal interval to which a measurement applies, apart from the temporal instant defined by the timestamp. Therefore, the s4watr:hasPhenomenonTime property has been defined in this extension to define the time for which the measurement applies to a feature of interest. The range of this property time has been defined as a time:TemporalEntity, which allows defining temporal intervals or instants.
+SAREF allows to define the temporal extent of a measurement by defining the timestamp for it (using the saref:hasResultTime property) and to define the temporal interval to which a measurement applies, apart from the temporal instant defined by the timestamp (using the saref:hasPhenomenonTime property).
Besides, the extension requires to be able to represent those devices that measure a certain feature of interest (and those features of interest that are measured by a device) independently of having measures from which this relationship could be inferred. Because of this, in this extension we have created four new properties to relate saref:Device and saref:FeatureOfInterest: s4watr:featureIsMeasuredByDevice, s4watr:featureIsControlledByDevice, s4watr:measuresFeature, and s4watr:controlsFeature.
