rdflib-shim

library1.0.3pypypi✓ verified 88d ago

rdflib-shim is a compatibility layer that smooths over breaking changes between rdflib 5 and 6, allowing code written for rdflib 5 to work with rdflib 6 without modification. Version 1.0.3 (latest) requires Python >=3.7. The library is maintained but low-churn (last release 2022).

rdflib_shim

✓ import rdflib_shim

The shim is imported before importing rdflib. No common wrong import reported.

Import the shim first, then use rdflib as usual with rdflib 6.

import rdflib_shim from rdflib import Graph, URIRef, Literal g = Graph() g.parse('http://example.org/test.ttl', format='turtle') for s, p, o in g: print(s, p, o)

Debug

Known issues

gotchaThe shim must be imported before any rdflib imports. If rdflib is imported first, the patching won't apply.

fix

Always put `import rdflib_shim` as the very first import in your module.

affects: all

deprecatedrdflib-shim may not be needed for new projects targeting rdflib 6+ directly. Its primary purpose is to ease migration from rdflib 5.

fix

For new code, consider writing directly against rdflib 6 APIs and skip the shim.

affects: >=1.0.0

Errors

Common errors & fixes

AttributeError: module 'rdflib' has no attribute 'RDF'

In rdflib 6, the RDF namespace is no longer available under rdflib.RDF; it moved to rdflib.namespace.

fix

Add `import rdflib_shim` before `import rdflib` to restore the old behavior.

AttributeError: module 'rdflib' has no attribute 'term'

rdflib 6 changed internal module structure. Some direct references to rdflib.term fail.

fix

Use `from rdflib.term import *` or import the shim first.

ImportError: cannot import name 'BNode' from 'rdflib'

In rdflib 6, BNode is not directly exported from rdflib.__init__; it's in rdflib.term.

fix

Either use `from rdflib.term import BNode` or install/import rdflib-shim.
