LionWiki is a minimalist file-based (doesn't need a database), templatable, extensible wiki engine that works from just one file (30KB). It supports page history, recent changes, interface localization, password protection (both writing pages and seeing), and much more through plugins (CAPTCHA, RSS, syntax for Tables). It's intended for small personal Web sites, notebooks, and other simple applications. Installation is very easy: just copy the file and create a directory.
GeboGebo is a wiki system written for tdbengine. It stores all data in a local database structure and thus provides an indexed fulltext search. It uses a simple syntax, and has user lists, pages history, a missing pages list, and a recent changes list. Image and file upload are possible, but can be disabled. This allows it to work as a small document management system. A blacklist allows you to lock existing pages from being edited or new pages from being created. It can also be run in static mode, where all pages are additionally held as static HTML pages.
Rhizome is a Wiki-like content management and delivery system that exposes the entire site including content, structure, and metadata as editable RDF. This means that instead of creating a site with URLs that correspond to a page of HTML, you can create URLs that represent just about anything. It was designed to enable non-technical users to create these representations in an easy, ad-hoc manner. For developers, this allows both content and structure to be easily repurposed and complex Web applications to be rapidly developed.
datecomm is a social networking and community portal that allows members to personalize their profile, upload a picture and music, link video and music, and invite any friends to join the network. It also features blogs, classifieds, forums, dating, and events. Developer licenses are available.
