Live Editor

Write triples in a shorthand notation, watch the graph redraw as you type, and copy the generated Turtle from the panel below. -a-> is rdf:type, -isa-> is rdfs:subClassOf; everything round-trips to standard Turtle.

Ctrl+Space (Cmd+Space on macOS) opens autocomplete over 144 terms from RDF, RDFS, OWL, XSD, SKOS, FOAF, Dublin Core, PROV, schema.org, BFO, RO, IAO, SIO and SHACL — picking one inserts its @prefix line for you.
