Factoidal — JSON-LD Playground

Paste JSON-LD, hit Run. Parsing (toRdf) and RDFC-1.0 canonicalization run in your browser, F*-extracted, loaded from this site's own npm/foafos package mirror — no npm install, no server round-trip. ← back to the main demo
JSON-LD support is Phase 1-3b: expanded form, inline @context, @reverse, container maps (@set/@list), and @base relative-IRI resolution all work. Remote contexts (a bare URL string as @context) are not supported yet — there is no context-loader/fetch step in JSONLD.Expand.fst. Try the "remote-context example" button below to see the honest failure rather than a silently-empty result. Current W3C toRdf score and the phase plan: jsonld-phase2-runner.md.
