SOSA extensions

Feedback from proof-of-concept of Harm Delba (Ugent - Imec)

Some extensions of SOSA seem less useful to me personally. For example, it is already difficult to find the definition of hasUltimateFeatureOfInterest because it is defined in a separate document. But when I look at the definition, you might as well use a SamplingFeature.sampledFeature property to make the link with the general feature of interest.

The actual purpose of Observation.UltimatefeatureOfInterest is when the SamplingFeature.sampledFeature is in itself a Sample, so if you have a Sample of a Sample. Eg you start with a larger area in which some smaller sampling areas are defined in which some points are sampled. Or a Drilling from which a core is retrieved (in itself a Specimen) from which a Sample is taken (also a Specimen) for further analysis. After several Sampling steps like these it becomes difficult to track down the original Object from which the first Sample was taken. With Observation.ultimateFeatureOfInterest you do not forget what real-world Object is the actual featureOfInterest.
