Link between FeatureOfInterest and xxxProperty
Back to Semantic Sensor Network Ontology.
Although it has not been resolved, hasProperty and isPropertyOf are de facto not in SOSA.
This page questions the existence of the link between FeatureOfInterest and xxxProperty in SOSA.
In old SSN, this link was materialized by properties oldssn:hasProperty and oldssn:isPropertyOf
In the current sosa, this link does not exist:

Maxime: it's strange that there is no link between FeatureOfInterest and xxxProperty in SOSA.
Armin, https://github.com/w3c/sdw/pull/572 : I think it was deliberately left out from SOSA.
Simon, https://github.com/w3c/sdw/pull/572 : Indeed, there was no connection between FeatureOfInterest and ObservableProperty in SOSA because that would have involved establishing something akin to the ISO 19109 General Feature Model, which is way beyond the scope of SOSA. It would also have likely involved either rdfs semantics (domain and range) or OWL semantics (owl:Restriction) which we agreed would not be used in SOSA.
Jano, https://github.com/w3c/sdw/pull/572 : Yes and let us not flood SOSA with more and more features otherwise we give up one the major design goal of being minimal and easy to use in the first place.

Option 1: add sosa:hasProperty and sosa:isPropertyOf in SOSA
