Owlready2 0.34 has been released!

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

Here are the changes:

• NEW FORUM ADDRESS: http://owlready.306.s1.nabble.com

• Support SPARQL property path expressions with parentheses without sequences, repeats or negative property set nested inside repeats

• Add define_datatype_in_ontology() global function for defining a new user-defined datatype in an ontology

• Class.instances() now takes into account equivalent classes (like other class methods such as .descendants())

• Add the LOADED(iri) SPARQL function

• Support Thing.is_a.append(...)

• Faster loading of very large quadstores

• list(onto.metadata) now lists the annotations present on the ontology

• Add OntologyClass and NamespaceClass argument to get_ontology() and get_namespace(), allowing the use of custom classes

• Bugfixes: - Accept UTF8 and latin encoding from reasoners (thanks Francesco Compagno) - Fix SPARQL query with a UNION without variables - Fix semantic type support in UMLS
