VOS is a library and network protocol for interlinked object structures, which can be easily distributed over networks. Notifications of changes are automatically sent to other applications/clients. VOS simplifies concurrent asynchronous programming, both within the same process or distributed over the network. Revision control (versions), access control, and other important features are built in. VOS object messaging also allows access from multiple languages.
VOS forms the basis for several applications including multiuser 3D virtual reality, web content management, and any other application requiring an infrastructure for distributed, dynamic data structures. A multipurpose GUI client application for a combined 3D/2D/WIMP browsing and development environment is available.
