I cannot think of a reason. How are you executing these rules? I tried a
similar rule from TBC, but the example with ?s ?p ?o is of course hard
to debug because all these triples are already there. Did you try a
variation where ?o is a constant just to verify the particular rule
actually fires?

Hi
trying to execute a SHACL rule that preserves all the triples during a
replace _except_ the ontology object and its properties
This gives me the expected results when executed against the target
graph..
CONSTRUCT {
?s ?p ?o
}
WHERE { ?this a owl:Ontology .
?s ?p ?o FILTER ( ?s != ?this )
}
but when I run it as a SHACL rule as below it returns nothing - other
rules are running OK..
is there some internal logic that stops it looking at owl:Ontology
nodes when executing rules? (or a better way of doing this : noting I
have a "replace=true" on rule execution because normally i want to,
this is a rule i want to use to override that behaviour )
:copy_graph
rdf:type sh:NodeShape ;
rdfs:label "copy original graph" ;
sh:targetClass owl:Ontology ;
sh:rule :SPARQLRule_1 ;
.
:SPARQLRule_1
rdf:type sh:SPARQLRule ;
rdfs:label "copy original graph" ;
sh:construct """CONSTRUCT {
?s ?p ?o
}
WHERE {
?s ?p ?o FILTER ( ?s != ?this )
}""" ;
.
