Mapping Between Two Renditions - Magazines
In addition to mapping between
alternative renditions, hot-spots
on a particular page can provide
links to other information.
In this case – links to individual
video messages from the
editors.

A List of Hot Spots- Magazines
A magazine generally contains a collection of
articles, and the articles have their own set of
metadata:
- Article Title (dc:title)
- Byline (dc:creator)
- Date (dc:date)
- Original Publication/Reprint Info
(Note: also applies to collection of short stories)

pages may not be legible
One solution is to provide a set of regions to
zoom in on as a traversal of the content.
Example: A list of cells in a comic page.
Can be thought of as a mapping from one
rendition, back to itself (with a different set of
media constraints/selectors)

• The key notion in Fixed Layout is “fixed”
› No dynamic layout
› Re-layout can cause a host of incompatibilities
› No font licensing issues
• The fixed rendition(s) is the basis
• Other renditions map onto the fixed version
›
But can be (and in our case, are) bi-directional

The basis is fixed
• Overlays are easy, because
• We strongly favor declarative markup that informs the
user experience over embedding the UX in (e.g.)
JavaScript

These are essentially images of pages, XML
describing a “spine” and related notions, and
