Re: [vwrap] what's wrong with starting small?

[Cristina Videira Lopes <[e-mail]>]

Thanks for bring back the conversation to interop, Morgaine :)

In the HG1.5, the user agent data that is ported around carries with it 
a collection of URLs (let's call them capabilities, just to make things 
more interesting for Meadhbh, hehe :) These URLs point to the user's 
services. They are an unbound list of name-URL pairs. One of them is the 
user's asset service. So the simulator talks to this URL for assets 
pertaining to this user. The policies controlling asset access by 
foreign worlds aren't supported yet, but the framework for supporting 
them is emerging -- some people call that HG2.0. The main elements are 
here: the home world knows in which other world the user is, at all 
times, and the world that's being visited knows that the user is who 
(s)he says he is.
