Owlready2 0.4 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.

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

PyPI download statistics available!

No official download statistics are available for PyPI (the Python Package Index).

I’ve managed to extract the download statistics for all Python modules, on a per-month basis, since may 2016.

The method is described here, and the entire dataset can be downloaded as a CSV file.

Owlready2 0.1 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.

The 2 - 0.1 version of Owlready is a full rewrite that integrates an optimized RDF quadstore. It can now load big ontologies (several millions of RDF triples).

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

Towards Owlready 2…!

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.

The development version of Owlready2 is available here: https://bitbucket.org/jibalamy/owlready2

Using Webex on ArchLinux

Webex is a videoconference system from Cisco. It works under Linux but it is only available in 32 bits… This tuto explains how to use it under ArchLinux 64 bits.

1- Install Firefox (32 bits), Java (32 bits) and Webex 32 bits dependencies

Install the 32 bits version of Firefox, Java, and the 32 bits libraries needed by Webex. For ArchLinux, you need to install AUR package bin32-firefox, bin32-jre, webex-meta.

2- Test Java in Firefox

Launch Firefox 32 bits and test the java installation from this page: https://java.com/en/download/installed8.jsp

If the Java plugin is not found by Firefox, verify the plugin presence (file /usr/lib32/mozilla/plugins/libnpjp2-jre8.so) and start Firefox after specifying the plugin directory, as following :

MOZ_PLUGIN_PATH=/usr/lib32/mozilla/plugins/ /usr/lib32/bin32-firefox/firefox32

3- Test Webex

Test Webex from this page : https://www.webex.com/test-meeting.html

Attention, seeing the interface is not enough to garantee that everything is OK. You need to wait until you see the following screen :
