This is a legacy-style Triples parser for NTriples provided by W3C Example: ```python p = W3CNTriplesParser(sink=MySink()) sink = p.parse(f) # file; use parsestring for a string ``` To define a context in which blank node identifiers refer to the same blank node across instances of NTriplesParser, pass the same dict as `bnode_context` to each instance. By default, a new blank node context is created for each instance of `W3CNTriplesParser`. ) _bnode_idssinkbufferfileline skolemizeNrS'Optional[Union[DummySink, NTGraphSink]] bnode_contextOptional[_BNodeContextType]cCsNd|_|dur ||_ni|_||dur||_nt|_d|_d|_d|_dS)NFr7)rWrRrSr rTrUrV)r"rSrYr#r#r$r%s zW3CNTriplesParser.__init__Ff-Union[TextIO, IO[bytes], codecs.StreamReader]rWboolr2Union[DummySink, NTGraphSink]cCst|ds tdt|dst|dstd|}||_||_d|_ ||_|jdur2 |j Sz|j |d WntyItd |jwq$) aParse f as an N-Triples file.
