How to parse N3 in RDFlib

Question

I am trying to convert a file into XML using the N3 parser in RDFlib but I am not sure if I am doing it right or even if I have the n3 plugin installed. This is what I have so far:

import rdflib
from rdflib import URIRef, Graph, Namespace
from rdflib.plugins.parsers.notation3 import N3Parser

g = Graph()
result = g.parse(file=open("lemon_example_fear.txt", "r"), format="application/n3")
print (g.serialize(format='xml'))

This is not working but if I was to reverse the order with a working XML file it works fine

This is the error I get:

rdflib.plugin.PluginException: No plugin registered for (application/n3, <class 'rdflib.parser.Parser'>)

If anyone has a link to where to download the n3 plugin or just fix what I am doing wrong it would be great!

I am currently Running RDFlib 4.0.1 so it should be included shouldn't it?

According to this answer to another one of your questions (in particular, check the list of available parsers link), the format argument would be n3, not application/n3. If you do need to use the MIME type for the argument, the N3 spec says that the MIME type should be text/n3, not application/n3.

Just change format='application/n3' to format='n3'. It works!
