WikiIndex - wikis, wiki people, wiki software, and wiki ideas
Hieraki2 is an Open source web content management system that allows you to organize digital documents in a hierarchical tree structure. Hieraki2 builds upon a new wiki system infrastructure providing for an easy way to write modular extensions for existing or new wiki page types. The term "wiki page" refers to the data structure that encapsulates text or binary data. The software uses an access control list to protect documents from being edited by unauthorized users.
