In this category, I will be treating everything that isn't natively a Web resource or a media object. At this point, this leaves the following types of opaque data object:

• Files
• Archives (e.g. Zip files)
• Applets, Plug-ins and Software Installers
• Scripts and Style Sheets
  • JavaScript/ECMAScript
  • CSS
  • XSLT
  • Fresnel
