Hi Michael,
sh:update is by default not doing anything in SHACL. It is a property
that can be used by extensions. One such extension is the DASH
suggestions framework supported by TopBraid:
http://datashapes.org/suggestions.html
Please take a look and let me know if this would help. It is currently
limited to constraint components, i.e. it is not yet possible to define
suggestions that would be for a specific constraint instance only.

I am attempting to insert a triple when a particular SHACL violation

get it right.
I have a Person class that has a property Comment. I can easily
update the Person by
INSERT {
?s ex:Comment "inserted Comments" .
}
WHERE {
?s rdf:type ex:Person .
I have tried to add the sh:update as a property constraint:
ex:Person
rdf:type rdfs:Class ;
rdf:type sh:Shape ;
rdfs:label "Person" ;
rdfs:subClassOf rdfs:Resource ;
sh:property [
sh:predicate ex:Comment ;
sh:datatype xsd:string ;
sh:minCount 1 ;
* sh:update """PREFIX ex: <http://example.com#>*
*INSERT {*
*?s ex:Comment \"inserted Comments\" .*
*}*
*WHERE {*
*?s rdf:type ex:Person . }""" ;*
] ;
sh:property [
sh:predicate ex:firstName ;
sh:datatype xsd:string ;
sh:minCount 1 ;
sh:name "first name" ;
] ;
sh:property [
sh:predicate ex:gender ;
sh:class ex:Gender ;
sh:description "A Person's gender" ;
sh:maxCount 1 ;
sh:minCount 1 ;
sh:name "gender" ;
] ;
sh:property [
sh:predicate ex:lastName ;
sh:datatype xsd:string ;
sh:description "last name" ;
sh:maxCount 1 ;
sh:minCount 1 ;
sh:name "last name" ;
] ;
sh:property [
sh:predicate ex:mother ;
sh:class ex:Person ;
sh:description "A Person's mother";
sh:maxCount 1 ;
sh:name "mother" ;
sh:nodeKind sh:IRI ;
sh:shape ex:FemaleShape ;
] ;
sh:update """INSERT {
?s ex:Comment \"inserted Comments\" .
}
WHERE {
?s rdf:type ex:Person . }""" ;
.
ex:Person
rdf:type rdfs:Class ;
