CitiWiki is a fork of the original WakkaWiki. The objective of CitiWiki is to create a platform for research into Wiki-related technologies. CitiWiki itself is being used to implement a wiki system for the Department of Computer Science that acts as a knowledge management system (KMS) to collect and organize knowledge related to Computer Science in general, with contributions from both CS students and staff.

CitiWiki is wiki software based on a fork of WakkaWiki. It is developed by the Department of Computer Science of City University of Hong Kong as a research and experimentation tool.
