python setup.py install --user

Or install releases from PyPI:

pip install prov2neo

Usage

prov2neo can be used both as a command line script and as a Python lib.

As a Command Line Script

usage: prov2neo [-h] [-f {provn,json,rdf,xml}] [-i INPUT [INPUT ...]] [-a ADDRESS]
                [-u USERNAME] [-p PASSWORD] [-n NAME]
                [-s {bolt,bolt+s,bolt+ssc,http,https,http+s,http+ssc}]

optional arguments:
  -h, --help            show this help message and exit
  -f {provn,json,rdf,xml}, --format {provn,json,rdf,xml}
                        input PROV format
  -i INPUT [INPUT ...], --input INPUT [INPUT ...]
                        input files, use '.' for stdin
  -a ADDRESS, --address ADDRESS
                        Neo4j address
  -u USERNAME, --username USERNAME
                        Neo4j username
  -p PASSWORD, --password PASSWORD
                        Neo4j password
  -n NAME, --name NAME  Neo4j target database name
  -s {bolt,bolt+s,bolt+ssc,http,https,http+s,http+ssc}, --scheme {bolt,bolt+s,bolt+ssc,http,https,http+s,http+ssc}
                        connection scheme to use when connecting to Neo4j

As a Python Lib

from prov.model import ProvDocument
from prov2neo.client import Client

# read graph from JSON serialization
graph = ProvDocument.deserialize(source="examples/horsemeat.json", format="json")

# create a prov2neo client
client = Client()
# connect to the neo4j instance
client.connect(
    address="localhost:7687",
    user="jane doe",
    password="**redacted**",
    name="database name",
    scheme="bolt"
)
# import the PROV graph
client.import_graph(graph)

prov2neo supports formats that the prov library provides:

• PROV-N
• PROV-O (RDF)
• PROV-XML
• PROV-JSON
