Subject: Re: again on numbering..
Hello,
some new inputs about this issue:

>standalone.
I think that $num could be useful also in accessing arrays, vectors
and similar structures what we could call "ordered collections".
Let's consider again this use case:
=football.team/$has$num$11/+player
@as.roma.calcio/$is$a/+football.team
we could index each player using $num${x} as follow:
@as.roma.calcio+player/$num$0/=curci
...
@as.roma.calcio+player/$num$7/=derossi
...
@as.roma.calcio+player/$num$10/=totti
etc.
Do you think this capability could be of help for XDI?
BTW maybe we can avoid the prefix $num and leave only ${num}, e.g.
$0, $5, $7 are valid XRIs which represent the number 0, 5, 7.
What do you think?
Bests,
Giovanni
