[Opensim-users] grid operation

[Diva Canto]

By "assets" I mean the data itself, the blobs/text/etc.
The region prims/primitems storage holds only references to that data.

Look inside OpenSim.db. There is no "data" there, only meta data and 
references to the data (by UUID) stored on the asset server.
