CiderCMS is a flexible CMS for small to mid sized websites.
The basic idea is that the user can define "types" which can be thought equal to database tables (which get created) consisting of attributes (columns) with a template for output and an auto-generated (but customizable) management interface.
Data is stored in a hierarchical tree like a folder/folder/document/text structure which reflects the organization of a typical website.
