Abstract

A system and method for coordinating multiple-user edits of shared digital data. A coordinating device may receive commands to edit shared digital data from multiple independently operated user computers. The coordinating device may determine that two or more of the commands from respective user computers are mutually exclusive, redundant or otherwise conflict. The coordinating device may incorporate one of the multiple commands into a global command queue and may annul the other(s). The coordinating device may transmit the global commands to all user computers to be executed locally for implemented the same shared digital data thereon.

Claims

1. A method for coordinating edits of shared digital data by multiple user computers, the method comprising:

In a coordinating device;

receiving commands to edit shared digital data from multiple independently operated user computers,

determining that two or more of the commands from respective user computers are mutually exclusive;

incorporating one of the multiple commands into a global command queue and annulling the other(s);

transmitting the global commands to all user computers to be executed locally for implemented the same shared digital data.

2. The method of claim 1, wherein a command received from one of the user computers triggers the coordinating device to restrict commands from the other user computers.

3. The method of claim 2, comprising, in the coordinating device, annulling commands from the other computers that pertain to editing the same region of the shared digital data as the trigger command.

4. The method of claim 1, comprising, in the coordinating device, giving one of the multiple computers temporary exclusive permission to edit a portion or the entirety of the shared digital data.

5. The method of claim 4, wherein the computer with exclusive permission to edit the portion or entirety of the shared digital data is the first of the user computers to transmit a command within a predetermined time period to edit the portion or the entirety of a document.

6. The method of claim 1, wherein commands are determined to be mutually exclusive when they relate to editing of the same or overlapping digital data.

7. The method of claim 1, wherein commands are determined to be mutually exclusive when they are transmitted or received simultaneously or within a predetermined time interval.

8. The method of claim 1, wherein each version of the shared digital data stored locally on each of the multiple user computers may be modified independently before implementing the global commands into the shared digital data.

9. The method of claim 1, wherein all user computers have equal priority to control the shared digital data.

10. The method of claim 1, wherein the user computers may have different priority for controlling the shared digital data.

11. The method of claim 1, wherein editing comprises modifying the content of the shared digital data.

12. The method of claim 1, wherein editing comprises modifying the display of the shared digital data.
