Abstract: An electronic whiteboard that displays a viewport into a workspace shared in a networked collaboration system is supported by a data structure referred to as a relationship record, which identifies a source object, a target object, and a type of relationship. In an attachment type relationship, the location of the source object is determined relative to the location of the target object. Therefore, input gestures that identify the target object, and move or resize the target object, result in a corresponding movement or resizing of the source object. Input gestures that identify the source object can be used to reposition the source object relative to the target object, or to disconnect the source object from the target object. Also, input gestures can be utilized to connect a source object to a target object in a relationship record.

Abstract: A collaboration system can be configured to support a large number of active clients in a workspace where the workspace is distributed into diverse groups of objects. While participating in the workspace, a first active client can consolidate a plurality of objects into a group. Actions taken on this group maintain the proportions and relative positions of the objects within the group. These actions are distributed to a second active client in the workspace wherein the second active client applies these actions to their copies of the objects thereby synchronizing the viewports of the first and second active clients. Actions on a group of objects include resizing, moving, pinning, deleting, and duplicating the group as a whole.
