   RE: [xml-dev] RDDL (was RE: [xml-dev] Negotiate Out The Noise)

[ Lists Home | Date Index | Thread Index ]

Umm... PDF and Flash aren't painting to the 
same device contexts are they, say one in which 
a 2D circle is drawn alongside a 3D spinning 
sphere?  I get in over my head at this point, 
but as I recall, the MS experience with Chrome 
was less than efficient, in fact, a dog.  

So, we can level the playing field but not 
the players.  In some sense, a composite 
document is like an all-stars game in which 
the problems of behavioral fidelity and 
performance can only be met by the very 
best players, and then only in a given 
location on a given day.  It is 
rough enough to get all the components 
to work realiably, the composite forces the author 
to also consider if his audience has all 
these players, is willing to download 
what he doesn't have, or says, Pass.

So it becomes very quickly, caveat vendor.

Optimization and caching. That is the job of the renderer. I assume a
renderer would not download a plugin each time a namespace qualified element
were encountered. At least I know that my browser does not download the PDF
or Flash plugin each time a document is encountered. Heck a really smart
renderer might even optimize across downloaded plugins.

I just want to create a level playing field in which namespace names can be
used as URIs and in which any inefficiencies so created can be optimized
away when something is demonstrated to be an actual rather than theoretical
bottleneck (remember that Ma Bell said the Internet would never work on
theoretical basis, perhaps it doesn't but nonetheless here we are.)
