Remove ANY triple from the RDF store, given its subject, predicate, and object. Despite the name it is not limited to object-property edges: the object may be an IRI (an ABox edge or a TBox axiom such as owl:disjointWith / rdfs:subClassOf) OR a literal value (an annotation like rdfs:comment) — the matching triple is removed in all cases. To remove the EXACT axiom a reasoner repair points at — which may physically live in an imported ontology graph and/or carry a typed/language-tagged literal — pass the optional graphName (e.g. "urn:vg:ontologies") and, for literal objects, objectIsLiteral=true with objectDatatype/objectLanguage. These map 1:1 onto explainDiagnostics.suggestedRepairs action.args (graph / objectDatatype / objectLanguage / objectTermType), so reasoner-computed repairs apply faithfully. Omitting them targets urn:vg:data and treats the object as an IRI (legacy behaviour).

Input schema
| Property | Type | Required | Description |
|---|---|---|---|
subjectIri |
string | yes | — |
predicateIri |
string | yes | — |
objectIri |
string | yes | — |
graphName |
string | no | Named graph the triple lives in (e.g. "urn:vg:ontologies"). Defaults to urn:vg:data. Required to remove an imported-schema axiom — a data-graph removal would silently match nothing. |
objectIsLiteral |
boolean | no | Set true when the object is a literal value (not an IRI) so it is matched as a Literal term, not string-coerced into an IRI. |
objectDatatype |
string | no | Datatype IRI of a literal object (e.g. xsd:integer) so "42"^^xsd:integer is matched exactly and a same-lexical "42" string is left untouched. |
objectLanguage |
string | no | Language tag of a literal object (e.g. "en"). |
