[Opensim-users] IAR Import question

[Justin Clark-Casey]

The --merge function just refers to folders, not inventory items.

In the first instance, this is because it's perfectly okay to have multiple copies of the same item in the same folder 
in SL inventory.  So you can't assume that an item which already exists is a dupe.

Possibly something could be done not to duplicate item entries but it's not straightforward because inventory items do 
get a new ID on upload.

I believe there are also issues where assets sometimes are duplicated and the same ID is not reused.  With a 
deduplicating asset service (SRAS or XAssets in the future) this isn't an issue but you still need to have the lists 
which link a given arbitrary asset ID to a single existing asset ID.
