A statement whose subject is a resource, an IRI or a prefixed name, is a Resource, its id the subject as written and its label the first rdfs:label written in it; a prefix directive is a Prefix. Every other statement, and every other triple, is kept and binds nothing. A statement that does not parse is skipped to its '.' and reported at its line, and the rest is read (recover). w3c-turtle.fbl, the plugin binding the four W3C tool types run, stays as it is; spec 035 binds the W3C RDF type's Turtle with this family in its tool description.",
