Based on OpenSim
Index
• User Data Portability– User can always use 1 pair of name,pass to login
to all of the VirtualWorlds• Asset Data Portability– User can keep the same apparence, inventory
items, ... In different VirtualWorlds.• The future of OpenSim, of Virtual World– VirtualWorlds shift to 3D internet

Things need us to do
• Modifications on “RegionServer”– Recognize user specified “Asset/InventoryURL”
• Modifications on “UserServer”– Also act as a “RP”(Consumer)
• Modifications on “Asset/InventoryServer”– Work independently, can serve different regions• Security• Performance
One More (difficult) Thing• But has to be done• About user’s additional information– Current OpenID2.0 only support a few fixed kinds of
information http://openid.net/specs/openid-simple-registration-extension-1_0.html
• “sreg.AssetServerUrl” is not in the list• We have many chioces– Make a VirtualWorld oriented OpenIDServer that
supports “AssetServerUrl”– Change the OpenID’s protocol, to enable customized
user information• http://www.dataportability.org/
