    skos:definition "LOKF is a semantic, ontology-grounded profile of the Google Open Knowledge Format (OKF v0.1). It preserves OKF's authoring model — a directory of markdown files, each with a small YAML frontmatter block describing one concept — but binds every concept, field, and relationship to established web vocabularies (schema.org, W3C DCAT, and W3C PROV-O). Because the frontmatter keys are LinkML slots mapped to IRIs, a LOKF concept file, once a LinkML-generated JSON-LD @context is attached, is simultaneously human-readable markdown AND valid JSON-LD that expands losslessly to RDF triples. The entire format is defined in this single LinkML schema, from which the JSON-LD context, JSON Schema, SHACL shapes, and an OWL ontology are generated." .
