What This Project Does

RDFLib

RDFLib is a pure Python package for working with RDF. RDFLib contains most things you need to work with RDF, including:

• parsers and serializers for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, Trig, JSON-LD and even HexTuples
• a Graph interface which can be backed by any one of a number of Store implementations
• Store implementations for in-memory, persistent on disk (Berkeley DB) and remote SPARQL endpoints
  • additional Stores can be supplied via plugins
• a SPARQL 1.1 implementation - supporting SPARQL 1.1 Queries and Update statements
• SPARQL function extension mechanisms

RDFlib Family of packages

The RDFlib community maintains many RDF-related Python code projects with different purposes. For example:

• rdflib - the RDFLib core
• sparqlwrapper - a simple Python wrapper around a SPARQL service to remotely execute your queries
• pyLODE - An OWL ontology documentation tool using Python and templating, based on LODE.
• pyrdfa3 - RDFa 1.1 distiller/parser library: can extract RDFa 1.1/1.0 from (X)HTML, SVG, or XML in general.
• pymicrodata - A module to extract RDF from an HTML5 page annotated with microdata.
• pySHACL - A pure Python module which allows for the validation of RDF graphs against SHACL graphs.
• OWL-RL - A simple implementation of the OWL2 RL Profile which expands the graph with all possible triples that OWL RL defines.

Please see the list for all packages/projects here:

• https://github.com/RDFLib

Help with maintenance of all of the RDFLib family of packages is always welcome and appreciated.

Documentation

Installation

The stable release of RDFLib may be installed with Python's package management tool pip:

$ pip install rdflib

Some features of RDFLib require optional dependencies which may be installed using pip extras:

$ pip install rdflib[berkeleydb,networkx,html,lxml,orjson]

Alternatively manually download the package from the Python Package Index (PyPI) at https://pypi.python.org/pypi/rdflib

Installation from the current development branch (for developers)

With pip you can also install rdflib from the git project with one of the following options:

$ pip install git+https://github.com/rdflib/rdflib@main

or

$ pip install -e git+https://github.com/rdflib/rdflib@main#egg=rdflib

or from your locally sourced project you can install it with one of the following options:

$ uv sync  # installs into a uv-managed venv

or

$ pip install -e .

Getting Started

RDFLib aims to be a pythonic RDF API. RDFLib's main data object is a Graph which is a Python collection of RDF Subject, Predicate, Object Triples:

To create graph and load it with RDF data from DBPedia then print the results:

from rdflib import Graph
g = Graph()
g.parse('http://dbpedia.org/resource/Semantic_Web')

for s, p, o in g:
    print(s, p, o)

The components of the triples are URIs (resources) or Literals (values).

URIs are grouped together by namespace, common namespaces are included in RDFLib:

from rdflib.namespace import DC, DCTERMS, DOAP, FOAF, SKOS, OWL, RDF, RDFS, VOID, XMLNS, XSD

You can use them like this:

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

g = Graph()
semweb = URIRef('http://dbpedia.org/resource/Semantic_Web')
type = g.value(semweb, RDFS.label)

Where RDFS is the RDFS namespace, XSD the XML Schema Datatypes namespace and g.value returns an object of the triple-pattern given (or an arbitrary one if multiple exist).

Or like this, adding a triple to a graph g:

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

The triple (in n-triples notation) <http://example.com/person/nick> <http://xmlns.com/foaf/0.1/givenName> "Nick"^^<http://www.w3.org/2001/XMLSchema#string> . is created where the property FOAF.givenName is the URI <http://xmlns.com/foaf/0.1/givenName> and XSD.string is the URI <http://www.w3.org/2001/XMLSchema#string>.

You can bind namespaces to prefixes to shorten the URIs for RDF/XML, Turtle, N3, TriG, TriX & JSON-LD serializations:

g.bind("foaf", FOAF)
g.bind("xsd", XSD)

This will allow the n-triples triple above to be serialised like this:

print(g.serialize(format="turtle"))

With these results:

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

<http://example.com/person/nick> foaf:givenName "Nick"^^xsd:string .

New Namespaces can also be defined:

dbpedia = Namespace('http://dbpedia.org/ontology/')

abstracts = list(x for x in g.objects(semweb, dbpedia['abstract']) if x.language=='en')

Features

The library contains parsers and serializers for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, JSON-LD, RDFa and Microdata.

The library presents a Graph interface which can be backed by any one of a number of Store implementations.

This core RDFLib package includes store implementations for in-memory storage and persistent storage on top of the Berkeley DB.

A SPARQL 1.1 implementation is included - supporting SPARQL 1.1 Queries and Update statements.

RDFLib is open source and is maintained on GitHub. RDFLib releases, current and previous are listed on PyPI

Multiple other projects are contained within the RDFlib "family", see https://github.com/RDFLib/.

Running tests

Running the tests on the host

Run the test suite with pytest.

uv sync --group tests
uv run pytest

Running test coverage on the host with coverage report

Run the test suite and generate a HTML coverage report with pytest and pytest-cov.

uv run pytest --cov

Viewing test coverage

Once tests have produced HTML output of the coverage report, view it by running:

uv run pytest --cov --cov-report term --cov-report html
python -m http.server --directory=htmlcov
