Abstract
A spatial event map system including server-side data processor that maintains a spatial event map which locates events in a workspace. The spatial event map includes a log of events, entries in the log having a location of an object of the event in the workspace and a time. The system includes logic to send messages including a location of an object of the event in the workspace and a time of the event to client-side network nodes; and to receive messages identifying events that create or modify an object, and to add corresponding entries to the log of events. The events can include history events that are sent to the other client-side network nodes, and added to the log for the corresponding history events, and ephemeral events that are sent to other client-side network nodes without adding corresponding entries in the log.
