Information Architecture for a Wiki

As I know that my company is considering using a Wiki for online documentation, and as we move to a more Agile environment, a Linkedin thread in the Agile Technical Writers Group caught my eye.  I'm going to provide the link to the whole article, as the information there would help anyone considering building a Wiki, but I've also pulled out a list of links scattered throughout the posts for ease of access.

 

• Link to the thread:  Has anyone created an information architecture for a wiki? Was it Agile-style? (Granted, wikis grow by themselves, but content growth can be guided by structure like vines are guided by a trellis.) 
• http://www.learningbywrote.com
• PHP online manual (It provides a good structure for providing both reviewed information and user contributions on all pages)          
• Yahoo Group about DITA Wikis       
• MediaWiki
• A demo on how to create a DITAWiki with spreadsheets
• Demo of using Open Source mind mapping tools for graphical mapping, and editors for outlining and  outputting their maps in OPML format and transformming that  into a DITA or HTML map (and generating stub topics if you want to get fancy).
