Sensing in SSN, Was: Agenda SSN meeting this week - 11-04-17 20:00 - 22:00 UTC

Dear Krzystof, all,

I read your explanations at  , but I don't understand
exactly what you suggest, and the reasons why you would do that.

About the Why:

If I understand well, you say that the users of the old SSN ontology were
confusing  oldssn:Sensing (which already was a sub class of
oldssn:Process), with oldssn:Observation

Can you bring some evidence for this statement in existing papers or

About the How:

if I understand well, what you suggest could be simply implemented in ssnx
as follows:

oldssn:Sensing a owl:Class ;
  rdfs:label "Sensing"@en ;
  rdfs:comment "Sensing is a process that results in the estimation, or
calculation, of the value of a phenomenon."@en ;
  rdfs:subClassOf oldssn:Process ; # this was in the old SSN
  rdfs:subClassOf sosa:Procedure ; # this is the new part
  rdfs:seeAlso "" ;
  owl:deprecated true ; # this is the new part
  rdfs:isDefinedBy <> .

 1. all of the terms defined in the oldssn: namespace in ssnx.ttl are
deprecated anyways;
 2. oldssn:Process is already asserted to be equivalent to sosa:Procedure.

So at the end of the day, what you suggest can be summarized as follows,
isn't it?

"create neither sosa:Sensing nor ssn:Sensing, just deprecate the old term."

Is there any other option you can suggest, or should we just vote +1 or -1
on this one?
