================
rdflib |release|
================
RDFLib is a pure Python package for working with `RDF <http://www.w3.org/RDF/>`_. It contains:
* **Parsers & Serializers**
* for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, JSON-LD, RDFa and Microdata
* **Store implementations**
* for in-memory and persistent RDF storage, including remote SPARQL endpoints
* **Graph interface**
* 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

Source Code
-----------
The rdflib source code is hosted on GitHub at `<https://github.com/RDFLib/rdflib>`__ where you can lodge Issues and
create Pull Requests to help improve this community project!
The RDFlib organisation on GitHub at `<https://github.com/RDFLib>`__ maintains this package and a number of other RDF
and RDFlib-related packaged that you might also find useful.
Further help & Contact
----------------------
If you would like more help with using rdflib, rather than developing it, please post a question on StackOverflow using
the tag ``[rdflib]``. A list of existing ``[rdflib]`` tagged questions is kept there at:
* `<https://stackoverflow.com/questions/tagged/rdflib>`__
You might also like to join rdflib's dev mailing list: `<https://groups.google.com/group/rdflib-dev>`__
The chat is available at `gitter <https://gitter.im/RDFLib/rdflib>`_ or via matrix `#RDFLib_rdflib:gitter.im <https://matrix.to/#/#RDFLib_rdflib:gitter.im>`_.
Glossary
--------
Here are a few RDF and Python terms referred to in this documentation. They are linked to wherever they occur.
.. glossary::
functional property
Properties than can only occur once for a resource, i.e. for any relation (triple, in RDF) ``x p y``,
if ``p`` is functional, for any individual ``x``, there can be at most one individual ``y``.
OWL
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 <https://www.w3.org/TR/rdf11-concepts/>`_ for more info.
RDF
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 <http://www.w3.org/TR/owl-overview/>`_ for more info.
