A Python version of the Blueprints property graph model interface

Project description

SYNOPSIS: Provides a layer to abstract the Python developer from the graph database system used

Following the set of interfaces provided by tinkerpop for Blueprints, this proyect aims to give Python developers a similar functionality. A set of abstract classes are defined in order to guide the design of implementations for the different graph database engines.


This is an experimental version only permitting partial functionality to:


The easiest way to get pyblueprints installed in your virtualenv is by:

pip install pyblueprints


This version of pybluerprints allows you to connect to graph databases by a Rexster Instance or through the neo4j-rest-client API. Therefore a Neo4j database can be accessed with both options. The Rexster instance also provides connection to the following databases:

  • TinkerGraph
  • OrientDB
  • DEX
  • Sail RDF Stores


Connecting to a Rexster instance

>>> from pyblueprints import RexsterServer, RexsterGraph
>>> #Connecting to server
>>> HOST = 'http://localhost:8182'
>>> server = RexsterServer(HOST)
>>> #List graphs availbale in server
>>> server.graphs()
[u'tinkergraph', u'gratefulgraph', u'tinkergraph-readonly', u'sailgraph', u'emptygraph']
>>> #Connecting to a given graph
>>> graph = RexsterIndexableGraph(server, 'tinkergraph')


Creating a graph object through the neo4j-rest-client API

>>> from pyblueprints.neo4j import Neo4jGraph
>>> g = Neo4jGraph('http://localhost:7474/db/data')

Creating an indexable graph object through the neo4j-rest-client API

>>> from pyblueprints.neo4j import Neo4jIndexableGraph
>>> g = Neo4jIndexableGraph('http://localhost:7474/db/data')

lease keep in mind to backup your data before trying this library.
