Attached is a proposal for URIs for functions in SPARQL.

Also includes is a list of all the op: and fn: operators/functions rq23 
mentions.  I produced that list of F&O qnames used with:

while(<>)
{
     @a = /((?:op:|fn:)[\w-]+)/g ;
     next if ( $#a < 0 ) ;
     print join("\n", @a), "\n" ;
}

which I haven't exhaustively checked.
