AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

RDFLib is a pure Python library for parsing, querying, and serializing RDF data in multiple formats (RDF/XML, Turtle, N-Triples, JSON-LD, and others), with built-in SPARQL 1.1 support and pluggable storage backends.

Low friction installation with only two lightweight runtime dependencies (isodate, pyparsing). Active maintenance with recent releases; last commit 2026-08-12 and 181 days since the 7.6.0 release indicate steady development.

BSD-3-Clause permissive license allows commercial and private use with minimal restrictions; attribution and license inclusion required in distributions.

Usage

pip install rdflib

from rdflib import Graph, URIRef, Literal
from rdflib.namespace import FOAF, XSD

g = Graph()
g.add((URIRef("http://example.com/person/nick"), FOAF.givenName, Literal("Nick", datatype=XSD.string)))
print(g.serialize(format="turtle"))

Requires Python 3.8.1 or later; optional features (Berkeley DB store, networkx, lxml) require additional dependencies installed via extras.

Verdict: RDFLib is a mature, actively maintained library with no known vulnerabilities, low install friction, and permissive licensing. It is well-suited for production use in semantic web and linked data applications. The 7.6.0 release is stable and supports current Python versions (3.8–3.14).
