Short answer: $profit{ $facet }{ $term }{ $resource } = $url;
Example:
#!perl
use strict;
use warnings;
use Data::Dumper;
$Data::Dumper::Terse++;
$Data::Dumper::Indent--;
my %profit;
while( ) {
chomp;
my( $resource, $url, $term, $facet ) = split /,/;
$profit{ $facet }{ $term }{ $resource } = $url;
}
print Dumper \%profit;
