Posh

Posh — the Prolog OWL Shell

Posh (Prolog OWL Shell) is a command line utility
that wraps the Thea OWL library to allow for advanced querying and
processing of ontologies, combining the power of prolog and OWL
reasoning.

To get the latest version of posh, you should use the posh branch in the Thea library on github. You can do this as follows:

git clone git://github.com/vangelisv/thea.git
cd thea
git co posh

After this, start a session:

bin/thea-poshj
