Re: [xdi] How to get from =markus/+email to the actual data

["Giovanni Bartolomeo" <giovanni.bartolomeo@uniroma2.it>]

Hello, one simple question regarding the subject "$" in the statement

$/$get//=markus/+email

is "$" referring to the authority which originates this message? E.g.  
if I'd be that authority, would the above statement be the same as

=giovanni/$get//=markus/+email

?

Thanks,
Giovanni
