Resource+categories

Our draft prototype resource database puts resources into the following categories:
 * application
 * implication
 * technology
 * content creation
 * application development
 * user skill

These categories are based upon the class outline I have been using:

Concepts Skills
 * Applications
 * Implications (for individuals, organizations and society)
 * Technology (communication, storage, memory and processing)
 * Application development
 * Content creation (text, image, audio and video)
 * User skills

The goal is to facilitate discover-ability.

What should our resource category taxonomy be?

What should our resource tag policy be? Should they be standardized or open-ended?
