RDFLib is a pure Python package for working with RDF. It contains:
Parsers & Serializers
for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, JSON-LD, RDFa and Microdata
for in-memory and persistent RDF storage, including remote SPARQL endpoints
to a single graph
or a conjunctive graph (multiple Named Graphs)
or a dataset of graphs
SPARQL 1.1 implementation
both Queries and Updates are supported

Here are a few RDF and Python terms referred to in this documentation. They are linked to wherever they occur.
- functional property¶
Properties than can only occur once for a resource, i.e. for any relation (triple, in RDF)
x p y, if
pis functional, for any individual
x, there can be at most one individual
The OWL 2 Web Ontology Language, informally OWL 2 or just OWL, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL 2 ontologies can be used along with information written in RDF, and OWL 2 ontologies themselves are primarily exchanged as RDF documents. See the RDF 1.1 Concepts and Abstract Syntax for more info.
The Resource Description Framework (RDF) is a framework for representing information in the Web. RDF data is stored in graphs that are sets of subject-predicate-object triples, where the elements may be IRIs, blank nodes, or datatyped literals. See the OWL 2 Web Ontology Language Document Overview for more info.
