rdfpipe adds a graph name to triples in the default graph, consequently breaking round tripping · Issue #1804 · RDFLib/rdflib (original) (raw)

I would expect to be able to round-trip quads with rdfpipe, but this does not work because rdfpipe labels quads in the default graph with a graph name and then serializes them with the injected graph name.

~/sw/d/github.com/iafork/rdflib.cleanish $ cat ./test/w3c/trig/trig-turtle-03.trig

Turtle is TriG

prefix : http://example/

[ :p 123 ; :q 456 ] :r 1 .
