When a server creates a resource on HTTP PUT, POST or PATCH requests such that the request’s representation data encodes an RDF document [RDF11-CONCEPTS] (as determined by the Content-Type header), the server MUST accept GET requests on this resource when the value of the Accept header requests a representation in text/turtle or application/ld+json [Turtle] [JSON-LD11].
