Abstract

A method and apparatus is disclosed herein for synchronizing distributed work. In one embodiment, the method comprises receiving first and second metadata entries, adding the first and second metadata entries to a set corresponding to a digital object, and providing access to first and second unique identifiers used for referencing the first and second metadata entries respectively, where the first and second unique identifiers are based on contents of the first and second metadata entries respectively.

Claims

1. A method comprising:

sending a first unique identifier that references a set corresponding to a digital object; and

receiving sequence number and unique identifier pairs for each metadata entry in the set.

2. The method defined in claim 1 further comprising:

identifying a temporal location of the first unique identifier among unique identifiers in the set.

3. The method defined in claim 2 further comprising:

receiving one or more additional entries for another party;

generating unique identifiers for the additional entries; and

comparing the generated unique identifiers with received unique identifiers to identify an order for the one or more additional entries and other entries in the set.

4. The method defined in claim 1 wherein the unique identifier in at least one of the pairs is a hash value.

5. An article of manufacture having one or more recordable medium storing instructions which, when executed by a computer, cause the computer to:

send a first unique identifier that references a set corresponding to a digital object; and

receive sequence number and unique identifier pairs for each metadata entry in the set.

6. An apparatus comprising:

a processing unit to send a first unique identifier that references a set corresponding to a digital object; and

an input unit coupled to the processing unit to receive sequence number and unique identifier pairs for each metadata entry in the set.

7. An apparatus comprising:

means for sending a first unique identifier that references a set corresponding to a digital object; and

means for receiving sequence number and unique identifier pairs for each metadata entry in the set.
