Re: "Responsive Ebook Design"

Hi,

+1 to Ivan's last comment. IDPF considers EPUB to be the portable document
profile of the Open Web Platform, and thus not something disjoint from OWP.
But on this list I take a reference to making a feature in EPUB "available
in OWP" not as a slight to EPUB but as shorthand for "making that feature
available for websites and Web-technology-based apps as well as in EPUB
publications".

But to Ivan's original comments, it may be that for online websites and
apps, media queries and HTTP content negotiation along with responsive
design techniques are already sufficient to support the scenarios that
multiple renditions facilitates for EPUB.The basic assumption of a packaged
portable document is that there is no server agent turning requests for
resources into representations on the fly (per the REST architecture of the
online Web), i.e. resource=representation. Multiple renditions gets past
this constraint at the publication level by enabling creators to deliver
together, and users to swap between, a high quality fixed layout
representation and a highly accessible reflowable representation, or
portrait and landscape representations,  but for a website it's possible
and commonplace to do that kind of thing via server intelligence. For
Web-technology-based apps (*), it would be more common to do address this
at a panel/scene level via responsive design not by having multiple
separate versions together (which is a pretty blunt instrument and which I
see also being less important down the road as we get better with
responsive design... template based pagination being another, IMO better,
way to skin this cat).

(*) is there a better name for this? "Web Apps" to me is ambiguous because
it also encompasses websites with some active server processing, and I
don't see Chrome Apps and Expedia.com as being the same kind of animal.
