What is a property?

Dear all,

Taking a look to a previous thread 
(https://lists.w3.org/Archives/Public/public-sdw-wg/2017Apr/0335.html) 
and to a recent pull request conversation 
(https://github.com/w3c/sdw/pull/792) it seems that there are two views 
on what a property is.

Is it something intrinsic to a feature?
   ns:OccupancyBuildingX a ssn:Property ;
     ssn:isPropertyOf ns:BuildingX .
   ns:OccupancyBuildingY a ssn:Property ;
     ssn:isPropertyOf ns:BuildingY .

Or is it something independent of a concrete feature?
   ns:Occupancy a ssn:Property ;
     ssn:isPropertyOf ns:BuildingX .
     ssn:isPropertyOf ns:BuildingY .

For those familiar with QUDT, is a Property related to a qudt:Quantity 
(first option above) or to a qudt:QuantityKind (second option)?

Note that both options are supported by current definitions and usage 
information, so we need to define clearly what we understand as a 
Property and update the definitions and examples to leave it clear.

Kind regards,
