Owlready2 0.36 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:

  • Support xsd:duration, including DATETIME_DIFF(), DATETIME_ADD(), DATETIME_SUB() SPARQL non-standard functions

  • Faster ontology operation (e.g. ontology deletion) on big quadstores

  • Automatically add .owl, .rdf or .xml to ontology IRI if the IRI itself does not yield an OWL file

  • Bugfixes: - Fix FusionClasses (= individuals belonging to several classes, i.e. multiple instanciation) when using several worlds - Fix OPTIONAL SPARQL clause when guessing variable types - Fix typo in undo entity destruction (thanks Lukas Westhofen) - Fix IRI from OWL namespace in SWRL rules - Fix Pellet explanation on inconsistent ontology - Fix MEDDRA parent-child relation of LLT in PyMedTermino2 - Make sure the filename is a file before returning (Thanks Nicolas Rouquette)
