surfrdf

SuRF 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.

Use the pypi repository to get the latest version of SuRF.

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()
somebody_else = Person()

somebody.foaf_knows = somebody_else
