• Navigational (goal) view: defining pages content and navigation behavior.
• Presentation view: defining presentation aspect like frame, frameset, and window.

Authoring Roles – regular LM• Author performs all (or at least most of)
the tasks required in creation of the learning material
Invited Tutorial, Madrid, Spain April 2008
