Re: Remote UI BoF at IETF63

Folks,


Since his name was taken in vain (vein?), Dave will proffer his own answer's 
to Harald's questions.  (OK, I'll admit it.  I'd be offering this response 
even if Harald hadn't referenced me.)

This is an effort to specify an open, platform-independent method of 
maintaining remote display objects, called widgets.  The application-level 
object-maintenance protocol that is described in 
<http://www.ietf.org/internet-drafts/draft-stirbu-lrdp-00.txt> is very nicely 
simple.
This means that the real work of pursuing such a service covers the 
network-based mechanics of connectivity, reliability, security, and so on.
That's a set of activities about which the IETF has better experience than 
anywhere else.

(I'm still working on my understanding of where this work fits, among a range 
of higher- and lower-level work, as well as work that might be called 
"competing" work. Therefore my response here is quite tentative.)
Existing open and deployed work has a focus either on the micro-behaviors of 
drawing graphics, or the macro-behavior of pure presentation.
The current work navigates space in between these two, creating and 
maintaining remote, user-visible "objects".  Hence it combines lessons learned 
from html, xml and object-oriented programming, into a specification of an 
object-oriented display and input environment, with presentation controlled by 
style templates.
Other comparable work is proprietary.

Although formally valid, use of the term "user interface" for this work is 
entirely unnecessary.  At the least it is too broad. In fact it has pretty 
much nothing to do with human factors, cognitive science, or usability.
On looking at the proffered draft document, calling the proposal something 
mundane like "remote widget exchange service" would be more precise and, I 
suspect, far more helpful.
