Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

The main new features of version 2 - 0.4 are:

• the defined relations can be queried for a given individual (using the .get_properties(), .get_inverse_properties() and .get_relations() methods)

• improvement of the .search() method, which now takes into account inheritance and inverse relations

• optimisation of recursive request in SQL

• several bug fixes

The new version can be downloaded from PyPI (Python Package Index): https://pypi.python.org/pypi/Owlready2

Owlready is a Python module for ontology-oriented programming. The version 2 currently under development keep the functionalities of the first version, but now relies on an optimized RDF quadstore in SQL. This version is now able to load big ontologies (several millions of RDF triples) with good performances.
