Re: [xdi] XDI graph as XRIs

[Nat Sakimura <n-sakimura@nri.co.jp>]

Hi Drummond,

Then, I suppose,

=markus
    +friend
        =bill.barnhill

will be expressed as =markus/+friend of which resolved value will be 
=bill.barnhill and the XRI itself is not =markus/+friend/=bill.barnhill.

Is that right?
