2. Borehole Hole in the ground along which we observed the material
For groundwater (and also Oil and Gas), an extraction, injection and monitoring feature
For geoscientists, it’s a feature that acts as a support for observation
Modelled as SF_SamplingFeature

3. Similar patterns, but different
Although GWML2 imports GeoSciML 4.1, GWML2 has its own Borehole class
Note that GeoSciML Borehole is an independent package

4. GeoSciML
Along this interval, we see
a portion of this feature

5. GWML Support for engineering details WellConstruction Screen Casing
Sealing
Filtration

6. GWML Well

7. Well to Borehole
Borehole describes the hole from which the water is drawn/observed

8. Modelling pattern for things along the well
Coverage pattern can be used with BOTH GeosciML and GWML

9. Considerations Boreholes as a 1D reference system in a 3D space
Entities located along a borehole path have both a relative location from the beginning of the borehole and an absolute location
Absolute versus Relative position
Lots of stuff needs to be located in this special relative spatial system
Had to shoehorn this SF_Specimen and OM_Observation
