Investigating Wiki Tools For Development of E-Sirah

Above is actually the tittle that i'll work on regarding my final year project, so far my understanding is that E-Sirah is an e-learning application for kids that will be developed using wiki tools/software. Through the web i've found that there are many kinds of wiki tools available, each wiki tools have their own features. I've look into one of the tools known as wikimedia, basicly wikimedia operate under php language and the features available is mostly similar to wikipedia. As there are so many tools, i'll have to identify the approriate tools that satify the features we'll need in developing E-Sirah.
