Proposal to fix ISSUE-117 and a question

Dear all,

Here you have a detailed proposal related to ACTION-283 to fix ISSUE-117.

As documented in the issue tracker, the proposal to solve this issue is 
the following:

* To create in SSN the ssn:isStimulatedBy property between 
ssn:Observation and ssn:Stimulus.
* To state in the SSN-DUL alignment that ssn:isStimulatedBy is a 
subproperty of dul:includesEvent.

These are the proposed changes to the ontologies, and below there is a 
question related to the issue and some comments.

OLD SSN
------------------------------
ssn:Observation rdf:type owl:Class ;
   ...
   rdfs:subClassOf [ rdf:type owl:Restriction ;
                     owl:onProperty dul:includesEvent ;
                     owl:someValuesFrom ssn:Stimulus
                   ] ,
   ...
------------------------------

UPDATES TO NEW SSN
------------------------------
ssn:Observation rdf:type owl:Class ;
   ...
   rdfs:subClassOf [ rdf:type owl:Restriction ;
                     owl:onProperty ssn:isStimulatedBy ;
                     owl:someValuesFrom ssn:Stimulus
                   ] ,
   ...

###  http://www.w3.org/ns/ssn/isStimulatedBy
ssn:isStimulatedBy rdf:type owl:ObjectProperty ;
                rdfs:isDefinedBy "http://www.w3.org/ns/ssn" ;
      rdfs:comment "Relation between an Observation and the Stimulus 
that triggers it." ;
          rdfs:label "is stimulated by" ;
                rdfs:seeAlso 
"http://www.w3.org/2005/Incubator/ssn/wiki/SSN_Skeleton#Skeleton" .
------------------------------

UPDATES TO SSN-DUL ALIGNMENT
------------------------------
###  http://www.w3.org/ns/ssn/isStimulatedBy
ssn:isStimulatedBy rdf:type owl:ObjectProperty ;
                    rdfs:subPropertyOf dul:includesEvent .
------------------------------

In the old SSN we use the owl:someValuesFrom restriction; isn't it too 
restrictive taking into account that Stimulus is not a "popular" class 
in SSN (http://w3c.github.io/sdw/ssn-usage/)?

Once we decide on this question, I can implement the changes.


And now two other comments unrelated to the issue. First, that the 
dul-alignment file should be changed to the Turtle serialization and, 
second, why are we using rdfs:seeAlso with a string value instead of 
with a URI value?
I.e.:
   rdfs:seeAlso 
<http://www.w3.org/2005/Incubator/ssn/wiki/SSN_Skeleton#Skeleton> .

Kind regards,
