purrdf-rdflib — the opt-in import rdflib shadow

This is a thin, pure-Python distribution that claims the top-level rdflib import name and re-exports purrdf's purrdf.compat.rdflib surface. With it installed, third-party code doing a literal import rdflib transparently runs on purrdf — no source changes.

pip install purrdf[rdflib]

import rdflib                       # resolves to purrdf's compat surface
g = rdflib.Graph()
g.parse(data="<http://example.org/s> <http://example.org/p> <http://example.org/o> .", format="nt")
print(g.serialize(format="turtle"))

from rdflib.namespace import RDF    # -> purrdf.compat.rdflib.namespace
from rdflib import URIRef, Literal  # -> purrdf.compat.rdflib.term
import rdflib.plugins.sparql        # -> purrdf.compat.rdflib.plugins.sparql

Collision caveat — do not co-install with real rdflib

This shadow and the genuine rdflib both own the rdflib import name and must never co-inhabit one environment. Whichever is resolvable on sys.path wins; installing both is unsupported and undefined. That is why this shadow ships as a separate distribution rather than inside the main purrdf wheel: environments that need the real rdflib (for example purrdf's own differential test oracle) simply do not install purrdf-rdflib.
