SPARQL endpoint

/sparql accepts GET and POST queries. The Script parser supports SPARQL SELECT, ASK, and CONSTRUCT. Use POST for long queries and send the correct SPARQL media type.
Result negotiation supports standard SPARQL result encodings and, when installed, HTML, CSV, and tab-separated renderers.

​
Graph Store Protocol

/rdf-graph-store implements GET, POST, PUT, and DELETE over the default or a named graph.
  • GET retrieves a graph.
  • POST merges triples into a graph.
  • PUT replaces a graph.
  • DELETE removes a graph.
Identify named graphs with the standard graph query parameter expected by the endpoint. Use RDF media types such as Turtle, RDF/XML, or JSON-LD that the running Neuron advertises.

Operational guidance

  • Put LIMIT on exploratory queries.
  • Restrict mutation privileges separately from query.
  • Validate and bound remote graph dereferencing.
  • Invalidate application caches after graph updates.
  • Treat blank-node identifiers as document-local.
  • Version domain vocabularies and contract/harmonized-interface namespaces.
