Method and apparatus for synchronizing how data is stored in different data stores

摘要

A method (and corresponding equipment and computer programs) by which a first and second device (11 12) synchronize how data is organized as folders in respective first and second data stores (11c 12c) maintained by the devices (11 12) based on exchanging messages (21) including data identification elements (28 29) that refer to the folders, with the data identification elements (28 29) provided in the message external to any reference to data units; or, more generally, based on the first device sending a message to the other and including in the message information about data in the first data store and also information about a change in the data structure of the first device, wherein the information about the data in the first data store is placed in the message in an element different from the element where the information about a change in the data structure is placed.

1. A method, comprising:
establishing a transport connection, between a first synchronization agent associated with a first data store in a first device and a second synchronization agent associated with a second data store in a second device; preparing a message comprising a command for synchronizing said second data store with respect to a change in the directory structure of said first data store, said command comprising at least one data identification element, embedded in said command, identifying a folder associated with at least one modification in the directory structure of the first data store, wherein the at least one data identification element is contained in at least one non-data element of the message and no data element is specified in said command, and wherein the at least one non-data element of the message is used to specify a folder identifier, an entire path of the folder and at least one state of the message; and communicating said message to said second synchronization agent via the established transport connection.
