CopyPublish= OpenSimulator Internals = This wiki documents the internal architecture of OpenSimulator for developers and contributors.

Overview
OpenSimulator has two main components:
ROBUST.exe -- handles grid-wide services: user accounts, inventory, assets, presence, and region registration. Multiple simulators connect to a single ROBUST instance. OpenSim.exe -- runs one or more regions. Handles objects, avatars, physics, scripting, and terrain. In standalone mode both processes are combined into OpenSim.exe.
The database layer is split to match: ROBUST owns the grid database, each simulator owns its own region database. Both live in the same database server instance as separate databases. In standalone mode the connector calls the service directly in-process. In grid mode it makes an HTTP call to ROBUST. Same interface either way.
