Nice!
Over at Cloudforest we started a MediaWiki (
http://www.cloudforest.com/wiki/Main_Page) but never really got much data into it. Turns out those pesky things called jobs got in the way. One plugin we are enforcing though is the Semantic and Semantic Forms plugins. That allows for easy data mining and easy form based data entry for inexperienced users.
One of my goals with the wiki (Axel the site owner did most of the work) was to be able to write some scripts to pull out plant info sheets which could be printed out. These could be used for things like informational pamphlets or, in our case quick bag stickers for our scion exchanges with blurbs for each variety.
We haven't really entered much data (newborn baby + job = no time) we got hungup on creating templates for different fruit, hopefully you surpass ours quickly.
