What is OpensimWorlds?
OpensimWorlds is a place to share and find Opensim archive files for loading and hosting on your own server.
OpenSim archives can save all the necessary asset data to fully restore the terrain, the textures of objects and their inventories when loaded onto a completely different system using a different asset database.
