Corporations have documents describing various aspects of their technical systems, including:

• Custom Applications
• Custom Development Frameworks
• Third Party Applications
  • Accounting
  • Bug Tracking
  • Network Management
• How To Guides
• User Manuals
• Software Tools
• Web Browsers
  • Development
    • IDEs
  • Graphics
    • GIMP
    • xv
  • Text Editing
  • File Transfer
    • ncFTP
    • WinSCP
• Hardware
  • Servers
    • Web
    • Database
    • Exchange
    • File
  • Network Devices
  • Printers

If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?)

A few constraints:

• The structure should not go beyond three levels deep.
• Avoid the word "and" in favour of two different categories.
• Keep the structure general: it should appy as broadly as possible.
• Target audience is primarily technical, but could be visible by anyone.
