This document appears to be notes from a presentation on the history and architecture of the PHP framework Ethna. Some key points: - Ethna was first released in 2004 and has gone through several major versions. Development accelerated after 2008. - It uses an MVC architecture with AppObject/AppManager handling core functions, templates rendered with Smarty, and a controller managing data flow between models, views and preforwarding. - Action forms are used to represent and validate submitted data from view templates.
