title: LOKF
abbreviation: LOKF
definition: Linked Open Knowledge Format - a semantic profile of OKF where every field and relationship is bound to a public vocabulary (schema.org / DCAT / PROV-O), so a bundle can be losslessly turned into a knowledge graph and queried with SPARQL.

`trust-engine.md` computes over the LOKF-specific surface: this plugin's trust labels and the fourteen relation fields that `src/bundle.ts` reads from the pinned schema. They are the specification's ten typed relations, such as `isPartOf` and `dependsOn`, plus `isReplacedBy`, `measures`, `memberOf` and `holder`. Schema validation of the LOKF layer itself is `ktl-registrar`'s job, not this plugin's.
