Thanks for your very helpful reply, Jonathan. It answered my general
question but I'm left with a couple of more specific ones.
Pl. see in line.

Yes, that's it. It's for data that is constant, for the purposes of the
script in question. But I am v. interested to know how you do this. Do you
do a Rose call and then iterate through all the objects creating a hash?
I've now written something to do this.

No I didn't mean the cached data (at least I don't think I mean that). Here
is a real example that leaves me baffled. Having already loaded all
products with Rose, I now want to see how many of a product are at a
particular location which comes from a one_to_many relationship with another
table locations. With my old hash method of doing this it would be
trivially simple : $product{locations}{$location}{stockqty}.
I'm thought it would be trivially simple with Rose too but it doesn't seem
to be.
$products = MG::Product::Manager->get_products(require_objects =>
['locations'];
So now $products is an array of all product information, just like %product
was a hash of all product info. But how do I get that stock quantity info
for a particular location out of the $products array?
$products->locations->$location->stockqty won't work of course
$products->locations(locationcode => $location)->stockqty won't work
either.
Is there a solution? Or do I just have to do another call to the DB?
