WikkaWiki

For the neopagan religion and religious movement, see Wicca.

WikkaWiki (often shortened as Wikka) is a free, lightweight and Standards-compliant wiki engine. Written in PHP, it uses MySQL to store pages. WikkaWiki is a fork of Wakka Wiki, to which a number of new features have been added. It is designed for speed, extensibility, and security. Released under the GNU General Public License.

History

In 2003, the development of Wakka Wiki came abruptly to an end, although a large community of users and contributors was still actively posting bugfixes, extensions and new functionalities. First released in May 2004 by Jason Tourtelotte, WikkaWiki rapidly grew into a project aiming to remain faithful to Wakka's heritage of a lightweight engine with readable and accessible code. WikkaWiki currently has an 8-strong official developer team and an active community of contributors.

Wikka vision

Compared to heavier wiki engines, which integrate several built-in functions, WikkaWiki's goal is to keep its core as small as possible while developing an architecture that supports easy extensibility through plugin modules. The latest version (1.1.6.3) has been released on May 7, 2007. It addresses an important number of security issues.

Wikka features

Among the distinctive features of this wiki engine:

• Support for different types of embedded elements:
