This is the developer blog for Twiki, one of the most powerful wikis.

Here are some things to consider up front:

* Pluggable authentication and authorization. In the beginning both are simple, but if you weave that simple assumption into the code, it will be hard to add finer grained control.

* Keep read latency low. This might mean some form of caching. Twiki is slow in my experience.

* Expose all features to a web service interface from day one. Don't weld functionality to the GUI. Side benefit: makes testing your software easier. See:

I think you'll find much of what you want by poking around the Twiki site.
