Greetings monks, I have a bunch of data that refers to a single thing. I need to choose the best representation of that single thing by using the qualities of the multiple different measurements. Due to the fact that I have to do about 3k of these things, the data structure has become a hash of a hash of a hash. ie: $hash{$individual thing}{multiple measurements of individual thing}{qualities of current measurement}. for example: 
$data{$name}{$measurement}{'SIZE'} = $size

I have ~3k of $name, and around 5 of measurement for each $name and there are 10 qualities such as size. In order to select the "best" one of these measurements for each name, I need to do some sort of selection on several of the different qualities. Thus, it seems I need to sort the inner hash. However, I'm not sure how to sort the qualities into descending order and keep the mapping of which measurement the quality applies to. For example: Name 1 has 5 measurements. The 5 measurements have SIZEs of 100, 200, 300, 400, and 500. If I want to order on the SIZE quality, how do I do this? It'd be great if this would work on qualities that are numbers and letters. Esentially I need to order the 10 different qualities in a variety of ways to find the "best" representation by those qualities. I'm more than happy to change the data structure if someone can recommend something better (I heard mention of AoA in the chatbox, but I'm not sure how to keep the measurement qualities separate in an AoA).
Thanks.
