[Opensim-dev] Proposal to eliminate the name, description and invType fields from the assets db table

[Teravus Ovares]

The only way for this to be extensable, and backwards compatible enough
really is to have the following structure.

InventoryItem ---->AssetUUID-----> DataHash

InventoryItem would be mapped to AssetUUID.  AssetUUID would have a many to
one relationship with DataHash..   this would allow for multiple UUIDs
generated the random way to be associated with a single data object in the
database.

Best Regards

Teravus
