rdflib-sparqlstore was merged into core rdflib on 2013-05-01 Future development will happen in core rdflib.
This is an RDFLib extension that provides an RDFLib Store around Ivan Herman et al.'s SPARQL service wrapper.
In essence, it allows a SPARQL 1.0 endpoint to behave as if it were a read-only RDFLib Store.
The extension also provides a read/write SPARQLUpdateStore, for use when the SPARQL endpoint supports SPARQL 1.1 update operations.
This extension has revived support for namespace bindings.
$ pip install rdflib_sparqlstore
Basic usage is
instantiate an RDFLib ConjunctiveGraph with "SPARQLStore" as the first positional arg and then
opening a known SPARQL endpoint
import rdflib g = rdflib.ConjunctiveGraph('SPARQLStore') g.open("http://dbpedia.org/sparql")
A SPARQLUpdateStore is also available, the example below shows how a graph of updates can be applied to an existing endpoint / store:
import rdflib g = rdflib.ConjunctiveGraph('SPARQLUpdateStore') g.open("http://localhost:3030/dataset/sparql", "http://localhost:3030/dataset/update")
If the store object is explicitly created with the
param set to
False, then rdflib.Graph can be used:
import rdflib import rdflib_sparqlstore store = rdflib_sparqlstore.SPARQLStore("http://dbpedia.org/sparql", context_aware=False) g = rdflib.Graph(store)
