My reading notes from a very interesting article advocating for blurring the perceived distinction between documents and interfaces:

• The job of Electronic documents: make it easy to create document elements like video, images, sounds and animations.
• The Job of Interfaces: present information to the user and make it easy to act on and manipulate that information.
• Argues for combining electronic documents and interfaces into documents that also act as user interfaces.
• Implementation: They made it possible for arbitrary document elements behave as interface elements (buttons).
• Document elements are either "active" (live, e.g. pressing a button does an action) or "passive" (editable).
• Examples:
  • Documents as control panels.
  • Documents as hyperlinks.
  • Creating buttons by using buttons.
  • Button actions edited as text with a text editor.
  • Buttons can be embedded in different media/elements, including text and graphics.
  • Buttons can take advantage of editor operations to highlight themselves when pressed.
  • Interface elements can be created and read by programs.
  • Buttons can be found and created rapidly using document tools.
  • Editor customisation and extensions
