Subject: Re: [xdi] Groups - On the extension of $word set in XDI (Draft-Contrib-OASIS-XDI-dollar-words-v03.pdf) uploaded
What would you think about adding a number to that variable, so you can use that feature more than once in a query? For example $any$1, $any$2, etc.
One advantage of this would be that the brackets wouldn't be necessary (thus keeping the syntax simple), since there would be implicit AND relationships between statements that use the same variable, and implicit OR relationships between those that don't.
Let me try to give an example to show what I mean:
=markus
$get
/
=giovanni
+friend
$any$1
$any$1+age
$lesser
"40"
=giovanni
+brother
$any$2
$any$2+age
$greater
"25"
This asks for all of Giovanni's friends younger than 40, and for all of Giovanni's brothers older than 25:
=giovanni/+friend/=Piergiorgio
=piergiorgio+age/$type$xsd$number/"25"
=giovanni/+friend/=mcoil
=mcoil+age/$type$xsd$number/"28"
=giovanni/+brother/=marco
=marco+age/$type$xsd$number/"30"
What do you think?
