A utility python script to convert GraphML files into the Amazon Neptune CSV
format for bulk ingestion. See
https://docs.aws.amazon.com/neptune/latest/userguide/bulk-load-tutorial-format-gremlin.html.

Example Using the Tinkerpop modern graph.

Download the tinkerpop-modern.xml graphml file.

$ curl https://raw.githubusercontent.com/apache/tinkerpop/master/data/tinkerpop-modern.xml -o tinkerpop-modern.xml

Execute the Python script to produce two csv files: nodes and edges.

$ ./graphml2csv.py -i tinkerpop-modern.xml 
infile = tinkerpop-modern.xml
Processing tinkerpop-modern.xml
Wrote 6 nodes and 18 attributes to tinkerpop-modern-nodes.csv.
Wrote 6 edges and 12 attributes to tinkerpop-modern-edges.csv.

Upload the csv files into your S3 bucket and bulk load into Neptune.
