We’ve released the version 0.6 of our distributed knowledge engineering tool OntoWiki. We re-engineered most part of it to support a more flexible architecture with themes and plugins. OntoWiki is based now on the Zend Framework and requires PHP 5.2 (because of the new __toString() behavior).
This is the first stand-alone version of OntoWiki. It still includes Powl but we decided to release both tools separately to provide a more user-friendly installation and setup process.
