Abstract
Updating of local object databases at client computers, dynamic inheritance, and event notification methods cooperate to provide a persistent object oriented multi-user domain capable of supporting multimedia presentation features for large numbers of users over conventional networks like the Internet. This includes distributing the objects of such a domain between a server and multiple clients and providing the objects with multimedia presentation features. Such a domain includes the persistence of conventional text-based MUDs and MOOs while also giving users the ability to vary or control a wide range of object attributes and properties. As a result, multimedia (e.g., graphical) presentation capabilities are combined with persistence and variability features of text-based MUDs and MOOs to provide a rich, dynamic, multimedia virtual world environment suitable for standard networks.
