Re: [Gmod-ajax] [Gmod-architecture] AJAX, WebService, Middleware, Chode

[Ian H. <ih...@be...>]

Now that we have a full-time gmod-ajax person (in the form of Mitch) 
it's probably about time to kick off a discussion on how to move towards 
our goals of community annotation (and what this means exactly) and full 
browser functionality including search, rich display, etc (and to what 
extent this should be GBrowse-like).

Chris, Andrew and I had a tete-a-tete a couple of months ago in which we 
scribbled some notes on the back of an envelope (or coffeeshop napkin). 
Andrew, do you have that napkin anywhere? Could we start by reprising 
those? I am running out the door right now but could dredge up my memory 
of the meeting if necessary.

One thing is that Mitch is away for a week or so. So probably the 
discussion will have to wait a little while for him to get back, before 
it gets really productive.

I.
