I am entering a rules book for a company and it has several races with each race having classes, feats, equipment, magical items, and spells. I created a container for each group and within each container was another container for each race. It is set up like this:
World Magic Items
> Race 1 Magic Items
>> Magic Item 1
>> Magic Item 2
> Race 2 Magic Items
>> Magic Item 1
>> Magic Item 2
For your project, I would so something similar where you have a container for potions, weapons, armor, wand, etc. Each container could have sub containers like weapons would have swords, daggers, hammers or use other categories.
And remember to use tags.
Just my $.02.
