Parsing trig file

[devm...@gmail.com]

Hey everyone, I am pretty new to using rdflib. I am attempting to parse a trig file I have and am having some issues. My goal is to build a tool to help clean my triples. I have a JENA 2 triple store that I exported into TRiG using JENA Tools. It has some issues I need to fix before I can upload it back into my database. I am hoping rdflib will be what I need to do this.

The first file I have is the complete triple store dump of my database, and is about 4.1 GB. When I attempt to parse it

e = Graph()
e.parse("content.trig", format="trig")

I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/trip_cleaner/venv/lib/python3.6/site-packages/rdflib/graph.py", line 1043, in parse
parser.parse(source, self, **args)
File "/trip_cleaner/venv/lib/python3.6/site-packages/rdflib/plugins/parsers/trig.py", line 161, in parse
p.loadStream(source.getByteStream())
File "/trip_cleaner/venv/lib/python3.6/site-packages/rdflib/plugins/parsers/notation3.py", line 434, in loadStream
return self.loadBuf(stream.read()) # Not ideal
OSError: [Errno 22] Invalid argument

The second file I have is a drastically reduced version of content.trig, with just the first 1000 lines (~250 triples). This is "successfully" parsed, however has nothing in the graph afterwords - len(e) = 0.

Any idea on where I am going wrong?

I have the same problem with a dbpedia file, did you happen to solve it?
