Elsie Wiki

Elsie is a wiki engine written in Java. It supports most popular wiki features including wiki markup syntax, content management (view, edit, attachment..), version control (history, diff, revert..), access control list, etc. Elsie implements an IoC-based wiki kernel, which loads service providers and wiki action plug-ins dynamically during runtime. Elsie also offers a clearly-defined, servlet-independent wiki API set via which a wiki may be extended and customized easily.
