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

(this maybe duplicate but we can sort that out later)


Joachim - named graphs are a continuing area of controversy.  What do you use 
them for?  and how do you decide ion the naming of the graphs?
