OxigraphStore

✓ from oxrdflib import OxigraphStore

✗ from oxrdflib.store import OxigraphStore

OxigraphStore is a top-level export; don't use the old submodule path.

Oxigraph

✓ from oxrdflib import Oxigraph

✗ from oxgraph import Oxigraph

The store class is 'OxigraphStore' in oxrdflib; 'Oxigraph' might be a different library.

Create an rdflib Graph backed by Oxigraph in-memory store. Parse and query RDF.

from rdflib import Graph from oxrdflib import OxigraphStore g = Graph(store=OxigraphStore()) g.parse("example.ttl", format="turtle") print(len(g)) # Query g.update("INSERT DATA { <http://example.com/s> <http://example.com/p> <http://example.com/o> .}") results = g.query("SELECT * WHERE {?s ?p ?o}") for row in results: print(row)

Debug

Known issues

breakingIn v0.3.0, the 'OxSled' and 'OxMemory' stores were removed and replaced by the 'Oxigraph' store. On-disk storage now uses RocksDB; migrate by dumping data with v0.2, upgrade, then reload.

fix

Use OxigraphStore() for both in-memory and on-disk. To persist data, specify a path: OxigraphStore(path='/path/to/db').

affects: >=0.3.0

deprecatedThe legacy format names 'ox-ttl', 'ox-nt', etc. are still supported but the new format names 'ox-turtle', 'ox-n-triples' are preferred and may become default in future releases.

fix

Use 'ox-turtle' instead of 'ox-ttl', 'ox-n-triples' instead of 'ox-nt', etc.

affects: >=0.4.0

gotchaNamespaces set via bind() are not persisted to disk. They are only available for the current session.

fix

Re-bind namespaces after reloading a store, or store prefix mappings separately.

affects: all

gotchaThe store does not fully implement all rdflib store methods; some operations (e.g., context management) may behave differently. Test your code thoroughly.

fix

Review oxrdflib's GitHub issues and test your usage; consider using raw pyoxigraph for advanced features.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'oxrdflib'

oxrdflib is not installed.

fix

pip install oxrdflib

ImportError: cannot import name 'OxigraphStore' from 'oxrdflib'

Version mismatch; OxigraphStore was added in v0.1.0.

fix

Update oxrdflib to the latest version: pip install --upgrade oxrdflib

AttributeError: 'OxigraphStore' object has no attribute 'query'

Query is performed on the Graph object, not the store directly.

fix

Use graph.query() instead of store.query(). See quickstart example.
