Re: Link between FeatureOfInterest and xxxProperty

A link from the featureofinterest to its property could be derived from
having a resolvable link to the type of the featureOfInterest

sosa:featureOfInterestType rdfs:range rdfs:Class

In practice however one would want to declare this once for a dataset - and
this is where RDF QB comes in - it allows you to declare such metadata
about a property - featureOfInterest is a dimension of a set of
observations.

Maybe an entailment rule that derives sosa:featureOfInterestType from a
qb:Dimension could be defined, we define the semantics of
sosa:featureOfInterestType, and then using qb and entailment is an
implementation option.  (this is the sort of thing that needs to go into
primers and future BP however)
