[Opensim-users] Question; What is the difference between and ASSET and a ITEM

[Marcus Llewellyn]

My understanding is that the item ID is used by inventory as a pointer to
an asset. Since NPCs don't have an inventory, they effectively borrow
inventory items from a user. Both the item UUID and the asset UUID are
needed for an appearance note card to work.
