RAA - hieraki

In short: wiki & hierarchy = Hieraki 1.0+.

Hieraki is an open source, wiki-like system that allows you to organize documents (such as tutorials for instance) in a highly structured fashion. Thus, Hieraki is ideal for applications where you want to impose a degree of structure that resembles most a file web browser.

Hieraki 1.0+ is based on Noc -- a multi-user learning object repository developed at Truman State University (for more information and screenshots go to: http://www2.truman.edu/~ah428/noc.html).

Features:
* attachments for documents
* version control for every document and attachment
* the ability to work on documents as a team of different users sharing
permissions across the repository
* moving folders and documents wherever you want by using a cut and paste method
* protecting documents from being editited by unauthorized users
* finding dead links in the repository with one mouse click
* caches to speed up the non-administrator view
