Reification pattern

Statements about statements

The reification pattern introduces individuals or tuples so that you can attach metadata to a relationship or proposition that would otherwise be expressed only as a single triple. RDF-level reification and related modelling options are covered in [AlHe2020]; graph query languages and graph-structured data in [AnAr2017].

In deriver.app, reification-style modeling often means introducing extra triples or entities to capture provenance, certainty, or time—plan migrations carefully because rules may depend on predicate shapes.
