SSN Thread for github issue 378 - Side effects of ssn:Observation being a kind of dul:Event instead of dul:Situation

Dear all,

If each github issue shall have its own thread on the SDW list, this is the
one for issue 378 - https://github.com/w3c/sdw/issues/378 :


if ssn:Observation <http://www.w3.org/ns/ssn/Observation> is a kind of
dul:Event <http://www.ontologydesignpatterns.org/ont/dul/DUL.owl#Event> instead
of a dul:Situation

there is an immediate side effect to resolve:

*axiom:*

ssn:Observation rdfs:subClassOf [ owl:onProperty dul:includesEvent ;
owl:someValuesFrom ssn:Stimulus ] .

*context axioms:*

ssn:Stimulus rdfs:subClassOf dul:Event .
dul:includesEvent rdfs:domain dul:Situation ; rdfs:range dul:Event .

*solution to solve the side effect:*

replace the mention of dul:includesEvent in axiom by a property that has
for domain and rangedul:Event

the only such DUL properties are: dul:isPreconditionOf, and
dul:isPostconditionOf.

Neither of them seem to fit,
so, should this axiom be simply deleted from the SSN-DUL alignment ?


Kind regards
