Usage: rdfpipe [-h] [-i INPUT_FORMAT] [-o OUTPUT_FORMAT] [--ns=PFX=NS ...] [-] [FILE ...]

A commandline tool for parsing RDF in different formats and serializing the resulting graph to a
chosen format. Reads file system paths, URLs or from stdin if '-' is given. The result is
serialized to stdout.

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -i INPUT_FORMAT, --input-format=INPUT_FORMAT
                        Format of the input document(s). Available input formats are:
                        application/rdf+xml, xml, text/n3, n3, text/turtle, turtle, ttl,
                        application/n-triples, ntriples, nt, nt11, application/ld+json, json-ld,
                        application/n-quads, nquads, application/trix, trix, application/trig,
                        trig, hext, patch. If no format is given, it will be guessed from the file
                        name extension. Keywords to parser can be given after format like:
                        FORMAT:(+)KW1,-KW2,KW3=VALUE.
  -o OUTPUT_FORMAT, --output-format=OUTPUT_FORMAT
                        Format of the graph serialization. Available output formats are:
                        application/rdf+xml, xml, pretty-xml, text/n3, n3, text/turtle, turtle,
                        ttl, longturtle, application/n-triples, ntriples, nt, nt11, json-ld,
                        application/ld+json, application/n-quads, nquads, application/trix, trix,
                        application/trig, trig, hext, patch. Default format is: 'n3'. Keywords to
                        serializer can be given after format like: FORMAT:(+)KW1,-KW2,KW3=VALUE.
  --ns=PREFIX=NAMESPACE
                        Register a namespace binding (QName prefix to a base URI). This can be
                        used more than once.
  --no-guess            Don't guess format based on file suffix.
  --no-out              Don't output the resulting graph (useful for checking validity of input).
  -w, --warn            Output warnings to stderr (by default only critical errors).
