As well as providing a means to document RPG material, Yagsbook provides some tools for organising and displaying it. The principle tool in this regard is the Encyclopedia. This takes a collection of articles and formats them ready for a website, handling cross-referencing between articles, content generation and topic sorting.
Originally, the Encyclopedia was designed for a static website (which was the only webspace available at the time). There are plans to provide a more dynamic and flexible interface.
Some preliminary work has begun on building the encyclopedia on top of Alfresco, using web scripts. This is simpler than writing everything from scratch. This will be built on top of Alfresco 3.2 Community, and should be available for public viewing as soon as I've figured out the best way to configure firewalls, proxies and virtual servers to expose Alfresco to the internet.
