Hello Len,
Len said:
Through an "HTML web browser". That is an accident of history. The
Internet doesn't really care that you use HTML as the containing markup.
It is the page metaphor triumphing over other modes and means. That can
change but I don't expect it soon. I do expect it to be relatively
sudden when it happens.
Didier replies:
AJAX (I now it's simply rebranding the actual capabilities) is slowly
changing that. We now have two metaphors:
a) Not (or very little) interactive pages. Just a small improvement over the
printed media (with the exception of video)
b) Interactive applications such as mail, word processors, order entry,
etc...
The latter are not so much based on the page model than on the application
model with overlays. The latter trend can potentially be re-enforced by XAML
even if XAML is not a W3 recommendation or an international or European
standard.
We can observe that even if it is possible to be "model driven" with a usage
of data encoded into XML and rendered in HTML after going through an XSLT
transformation, this method is not used on the client side and is sometime
used on the server side. I attribute this lack of usage to the fact that
current technologies such as xml/sql or xquery allows us to easily package
data coming out of RDB in XML but do not easily allows us to update the RDB
as easily without add-ons to the query engines. When round trips will be
easily performed and if the data publisher has vested interest to do so, we
will probably see more XML usage and more "model driven" applications.
Cheers
