I am parsing triple files and adding the triples into my local triplestore.
Code Snippet:
graph = ConjunctiveGraph('Sleepycat')
graph.open("mytriplestore", create=False)
g = Graph()
g.parse("filename.ttl", format="ttl")
for t in g:
graph.add(t)
Instead of iterating over every triple, is it possible to add the parsed content to the triplestore in bulk?
What I have tried so far:
Attempt 1:
graph.add(g)
Error:
File "/usr/local/lib/python2.7/dist-packages/rdflib/graph.py", line 1345, in add
s,p,o,c = self._spoc(triple_or_quad, default=True)
File "/usr/local/lib/python2.7/dist-packages/rdflib/graph.py", line 1326, in _spoc
return s,p,o,c
UnboundLocalError: local variable 's' referenced before assignment
Attempt 2:
graph.addN(g)
Error:
File "/usr/local/lib/python2.7/dist-packages/rdflib/graph.py", line 1363, in addN
