Abstract

A computer-implemented method for receiving information at a first device is provided. The method includes storing a first data object on the first device in a first device-specific representation, receiving a batch of information in response to the first device transitioning from an off-line state to an online state, processing the modification event to recover the modification, updating the first data object based on the recovered modification, and transmitting an acknowledgement indicating that the modification event was successfully processed by the first device. The batch of information includes a modification event. The content of the batch was determined based at least on a state of data stored on the first device. The modification event was generated based on at least a modification made to a second data object stored at a second device in a second device-specific representation.

Claims

1. A computer-implemented method for receiving information at a first device, comprising:

storing a first data object on the first device in a first device-specific representation;

receiving a batch of information in response to the first device transitioning from an off-line state to an online state, wherein the batch of information includes a modification event, a content of the batch having been determined based at least on a state of data stored on the first device, the modification event having been generated based on at least a modification made to a second data object stored at a second device in a second device-specific representation;

processing the modification event to recover the modification;

updating the first data object based on the recovered modification; and

transmitting an acknowledgement indicating that the modification event was successfully processed by the first device.

2. The method of claim 1, the batch of information having been transmitted by the second device.

3. The method of claim 1, the batch of information having been transmitted by a third device, the third device being different from the second device.

4. The method of claim 3, wherein the modification event is a first modification event, the first modification event having been generated by the third device by resolving a conflict between a second modification event generated by the second device representative of the modification made to the second data object and a third modification event representative of a modification made to a third data object on a fourth device.

5. The method of claim 1, wherein the modification event comprises an email.

6. The method of claim 5, wherein said processing comprises:

parsing the email to recover the modification event.

8. The method of claim 1, further comprising:

queuing the modification event in a buffer.

7. The method of 6, wherein the modification event is included in an attachment to the email.

9. A computer system for receiving information at a first device, comprising:

a storage for storing a first data object on the first device in a first device-specific representation;

a module configured to receive a batch of information in response to the first device transitioning from an off-line state to an online state, wherein the batch of information includes a modification event, a content of the batch having been determined based at least on a state of data stored on the first device, the modification event having been generated based on at least a modification made to a second data object stored at a second device in a second device-specific representation;

a module configured to process the modification event to recover the modification;

a module configured to update the first data object based on the recovered modification; and

a module configured to transmit an acknowledgement indicating that the modification event was successfully processed by the first device.

10. The computer system of claim 9, the batch of information having been transmitted by the second device.

11. The computer system of claim 9, the batch of information having been transmitted by a third device, the third device being different from the second device.

12. The computer system of claim 11, wherein the modification event is a first modification event, the first modification event having been generated by the third device by resolving a conflict between a second modification event generated by the second device representative of the modification made to the second data object and a third modification event representative of a modification made to a third data object on a fourth device.

13. The method of claim 9, wherein the modification event comprises an email, further comprising:

a module configured to parse the email to recover the modification event.

14. The computer system of claim 9, further comprising:

a module configured to queue the modification event in a buffer.

15. A computer readable medium carrying one or more sequences of one or more instructions for execution by one or more processors to perform a method for processing memory requests, the instructions when executed by the one or more processors, cause the one or more processors to:

store a first data object on the first device in a first device-specific representation;

receive a batch of information in response to the first device transitioning from an off-line state to an online state, wherein the batch of information includes a modification event, a content of the batch having been determined based at least on a state of data stored on the first device, the modification event having been generated based on at least a modification made to a second data object stored at a second device in a second device-specific representation;

process the modification event to recover the modification;

update the first data object based on the recovered modification; and

transmit an acknowledgement indicating that the modification event was successfully processed by the first device.

16. The computer readable medium of claim 15, the batch of information having been transmitted by the second device.

17. The computer readable medium of claim 15, the batch of information having been transmitted by a third device, the third device being different from the second device.

18. The computer readable medium of claim 17, wherein the modification event is a first modification event, the first modification event having been generated by the third device by resolving a conflict between a second modification event generated by the second device representative of the modification made to the second data object and a third modification event representative of a modification made to a third data object on a fourth device.

19. The computer readable medium of claim 15, wherein the modification event comprises an email.

20. The computer readable medium of claim 15, further comprising the processor to:

queue the modification event in a buffer.
