How to please

[Alex Leshinsky <al...@iname.com>]

There’s an eerie feeling in me that this question has been asked and answered a million times.
 Being in the grip of my decades long RDB programming, I can’t seem to decide what is the “JCR way” to deal with this:

 I need to associate certain objects, lets call them “items”, with a classification named “category”. Categories have a hierarchical structure and sit in a tree outside items.
 An item can be associated with any node in the Category tree.

 I’m aware that David calls IDs evil. So, how do I model that without risking to burn in hell?
 Many thanks!

Dunno about pleasing lords of evils, but maybe you can model it with a
triplet: source > relationship > target. In your case source is the
"item", relationship is "classifiedUnder" and target is "category".
You'll have one of such triplet per item associated in a
classification.

Or with references, where your "classification" nodes have (virtual)
item children where each of those children is a reference to the real
"item" node.

Hope this helps.
