=== Core Data Structures ===

 OpenSim/Framework/

Contains the fundamental data types that flow between all parts of the system. Neither ROBUST nor the simulator can function without these.

Key types:

{| class="wikitable"
! Type !! Notes
|-
| AssetBase || Asset metadata and binary data -- passed between asset service and callers
|-
| GridRegion || Region descriptor -- returned by GridService queries, used by simulator and ROBUST
|-
| InventoryItemBase || Inventory item -- passed between inventory service and callers
|-
| InventoryFolderBase || Inventory folder
|-
| RegionInfo || Region configuration -- loaded from Regions.ini, used by simulator startup
|-
| UserAccount || User account data -- passed between UserAccountService and callers
|-
| UUID || OpenMetaverse UUID wrapper -- used everywhere as primary identifier
|}

Also contains utility classes used by both processes:

{| class="wikitable"
! Class !! Notes
|-
| Util || General utilities: coordinate conversion, string helpers, Unix timestamps, UUID parsing
|-
| Constants || Grid constants: RegionSize, MaximumRegionSize, region coordinate limits
|-
| RegionFlags || Enum of region flag bitmask values -- used by GridService and simulators
|-
| AssetType || Enum of asset type numbers
|-
| AssetFlags || Enum of asset flag bitmask values
|}
