AboutSuRF is a Python library for working with RDF data in an Object-Oriented way. In SuRF, RDF nodes (subjects and objects) are represented as Python objects and RDF arcs (predicates) as their attributes. SuRF is an Object RDF Mapper (ORM), similar in concept to Object Relational Mappers like SQLAlchemy. SuRF was inspired by ActiveRDF for Ruby. DocumentationCheck the latest documentation at: http://packages.python.org/SuRF/ An outdated presentation of SuRF at EUROPYTHON 2009 is available here, although the internals of SuRF have changed with the release of version 0.5.0 - most notably the plugin architecture, much of the public interface still remains the same; See slideshow here: Setup and useUse the pypi repository to get the latest version of SuRF. $ easy_install -U surf In order to install surf and it's available plugins just do the following $ easy_install -U surf $ easy_install -U surf.allegro_franz $ easy_install -U surf.sesame2 $ easy_install -U surf.sparql_protocol $ easy_install -U surf.rdflib SuRF can also be embedded in your code, for an example on how to do it have a look here: http://packages.python.org/SuRF/install.html#loading-plugins-from-path-or-running-surf-in-embedded-mode SuRF Plugins are available for the following keys:

Quick Startfrom surf import *
store = Store( reader='rdflib',
writer='rdflib',
rdflib_store = 'IOMemory')
session = Session(store)
print 'Load RDF data'
store.load_triples(source='http://www.w3.org/People/Berners-Lee/card.rdf')
Person = session.get_class(ns.FOAF['Person'])
all_persons = Person.all()
print 'Found %d persons that Tim Berners-Lee knows'%(len(all_persons))
for person in all_persons:
print person.foaf_name.first
#create a person object
somebody = Person()
