Hi Stephen, hi Andy, I feel somewhat sorry for asking my question naively, just having verified that Jena supports N-quads, and not aware that the SPARQL 1.1 spec does not support it.
My use case could have been fulfilled simply with ntriples. What I wanted to do is feeding a PHP json-ld library (expecting quads), for converting the construct output to json-ld. In the meantime, I figured out that with "output=nt" I can get ntriples from Fuseki, and that JsonLD works fine with it (the errors with the other library were not related to quads/triples, too). So I cannot add a valid use case here - sorry for this, Joachim -----Ursprüngliche Nachricht----- Von: Andy Seaborne [mailto:a...@apache.org] Gesendet: Sonntag, 21.

What do you use them for? and how do you decide ion the naming of the graphs? Andy
