- OWL and RDF authors inspecting ontology structure
- Worth noticing
- The Orchard example renders “bears some Fruit” and “planted in only Plot” as readable restrictions; the inline opener notes a 2,000,000-character limit.
Field notes
Inputs can be supplied as a file, URL, or pasted text; the page lists Turtle, N-Triples, RDF/XML, JSON-LD, and Avouch YAML, with exports to RDF formats plus SVG and PNG. The example shelf includes FOAF, an OWL shop, library lending, clinic visits, subscription billing, insurance claims, a refund policy, and a deliberately broken file; the inline opener documents a 2,000,000-character limit.
