Figure 18 : Association class between a GW_HydrogeoUnit and GW_HydrogeoVoid.
Void properties are traditionally assigned to the hydrogeologic unit, while they are in reality a measurement of the relation between a unit and its voids. For convenience, the
feature of interest of the OM_Measurement values of the properties SHALL link to the feature at the gwVoidUnit end of the association.

Analytical results are modelled as OM_Observation having GW_Constituent as features of interest see Figure 19. A typical analytical procedure involves a sampling feature
such as a SF_Specimen and a series of OM_Observations reporting on some properties of the feature of interest.

Figure 19: The pattern for analytical results.
By referring to the real world identifiable feature using the sampleFeature property and using the observation featureOfInterest to constituent of the fluid body, this pattern
permits a detailed description of composition of various part of the fluid body.
