Request for feedbacks: three extensions of EPUB

[MURATA Makoto <eb2m-mrt@asahi-net.or.jp>]

Dear colleagues,

I would like to solicit comments on three specifications
from the IDPF Advanced/Hybrid Layouts WG.  XMLers
might think that the first and second provide out-of-line
links dedicated to some types of ebook navigation.

EPUB Multiple Renditions
http://www.idpf.org/epub/renditions/multiple/epub-multiple-renditions.html
This specification defines the creation and rendering of
EPUB Publications consisting of more than one Rendition
(a set of resources such as HTML or SVG content documents).


EPUB Region-Based Navigation
http://www.idpf.org/epub/renditions/region-nav/epub-region-nav.html
The purpose of this document is to describe how
guided navigation through one rendition can be
implemented using embedded Regions of Interest
in the Navigation document.

Previews in EPUB
http://www.idpf.org/epub/previews/epub-previews.html
This specification, Previews in EPUB, describes how
preview content can be included in EPUB Publications.


Regards,
Makoto (co-chair of the IDPF AHL WG)
