loadRdf
Load ABox instance data — subjects appear as canvas nodes. Use for individual/data triples. To load a schema or ontology without adding canvas nodes, use loadOntology instead. OWL RESTRICTIONS: loadRdf is the simplest way to assert axioms with blank nodes — all triples created atomically. Prefixes ex: owl: rdf: rdfs: xsd: are pre-loaded — do NOT include @prefix lines for them. Pattern (no @prefix needed): `ex:SalamiPizza owl:equivalentClass [ a owl:Restriction ; owl:onProperty ex:hasPart ; owl:someValuesFrom ex:SalamiTopping ] .` Alternatively use addTriple with blank-node labels (see addTriple description). The blank-node restriction individual appears in the TBox canvas view after loading.
