DOCUMENT SYNCHRONISATION ON PROTOCOL NOT USING STATUS INFORMATION Russian patent published in 2013 - IPC G06F17/00 

FIELD: information technology.

SUBSTANCE: first version and at least one cell associated with the document are received, wherein at least one cell has a cell identifier and the cell identifier is associated with the first version, having at least one first version identifier. Each of the at least one first version identifiers presents cell status at a moment in time, and the coverage area defines a plurality of cells and versions, the coverage area including at least one root object. Updates for a first computing device are received. The updates indicate the identifier of the updated version, associated with each cell, associated with the document. The first version of each cell is stored if the first version identifier matches the identifier of the updated version of the cell. A new version of each cell is generated, wherein generation of the new version includes assigning a new version of the identifier of the new version if the identifier of the first version of the cell does not match the identifier of the updated version of the cell. Any cell on which there were no links in root objects is deleted and the document is synchronised by replacing cells with a new version of each cell.

EFFECT: reduced volume of altered information.
