A column that a link the caller can see uses also gets a datalinks:Value node for each distinct value, named by the value when it is short; a cell holding 2 or more values gets a node of its own, whose datalinks:element are its values. Each exact or geo link the caller can see adds an edge from a cell to each cell it matches, as DataLinks matches them; a cell that matches more than 1000 rows through one link fails the stream: its last line is a comment that names the link and the cell and says how to change the link. Other IRIs are made from names. The response is compressed when the client sends Accept-Encoding. The ontology itself is not part of this stream. Each dataset is a named graph in N-Quads and TriG. The serialisation comes from the format query parameter, else the Accept header, else Turtle; only streaming formats are accepted. A failure after the response has started closes the connection before the final chunk, so a client detects the truncation. ## OpenAPI ````yaml /api-reference/openapi.yml get /rdf/{username}/{namespace}/data openapi: 3.0.3 info: title: DataLinks version: 3.16.0 servers: - url: https://api.datalinks.com/api/v1 description: production server security: - bearerAuth: [] - openId: - implicit paths: /rdf/{username}/{namespace}/data: get: tags: - rdf summary: Stream a namespace's rows as RDF description: >- Streams every row the caller can view, as a resource of its dataset's class with a literal for each cell; a row's IRI is minted under /.well-known/genid/ for this export only.
