OOOGUI is a dynamic CMS that lets you define your data structure (objects, relations between objects, queries on objects), and lets you create public and private HTML pages to view and modify your content. All of this is done through a WYSIWYG interface. OOOGUI is multilingual, manages role based permissions, and generates PHP and Smarty code that you can customize for your needs. Other features include an easy installation wizard, rich HTML and PHP editors, automatic resampling of uploaded images, automatic flv conversion of uploaded videos, automated site replication, caching of all queries, caching of all resized images, multiple sites with one backend, and creation of pages and navigation through drag and drop. The data model can be modified at production time, and all frontend pages can be regenerated with one click. The frontend pages have inline content administration.
