Instance Method Details

#emit_extra_triples(subject_uri, _mapping) ⇒ Object

Hook invoked by Glossarist::Rdf::LutamlTurtleTransformExt. Emits direct SKOS predicates alongside the reified SKOS-XL / gloss forms, so consumers that only speak plain SKOS (no SKOS-XL) see the labels, definitions, notes, and examples as plain literals.
