Abstract

Provided are a method, system and device for collaborating on electronic documents. According to the method, a data structure representing the content of a shared document is maintained on each computer system participating in a collaborative session. As user input is received by one of the computer systems to modify the document, the data structure is updated to reflect the modification. In response to the modification, changes to the data structure are periodically identified and collected as a revision identifying only changes to the data structure as a result of editing since the previous revision was made. Revisions are packaged and sent to participants in each sharing session. The revisions are merged into copies of the data structures stored on the computer systems participating in the session.

Description

[0001] Cross References to Related Applications [0002] This statement claims priority to US Provisional Patent Application Serial No. 60 / 563.685, entitled "Shared Session Features for OneNote," filed April 20, 2004, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a method and device for cooperating on electronic documents, in particular, to a method and device capable of performing near real-time cooperation on electronic documents through multiple computer systems. Background technique [0004] With the advent and growth of the Internet came network computing applications that allow remote computer users to work together on common tasks. For example, there are remote users that allow remote users to view a common whiteboard, view and interact with a slide show, chat with each other, and perform other functions in a collaborative manner. This procedural approach often increases productivity for users who...
