Abstract:
A method of operation of an electronic record storage system having a plurality of stored records, each record having a record identifier, content which may be changed from time to time, and a version identifier which is changed when the content of that record is changed, wherein the content of each record is printable from time to time, the method comprising the steps of:printing a document which includes (a) the content of a record, and (b) a marking from which the record identifier and version identifier can be derived; subsequently scanning the marking on the print to produce marking image data; deriving from the marking image data a scan-derived record identifier and scan-derived version identifier; using the scan-derived record identifier to access a current version of the record and to obtain a currently-stored version identifier of the record; comparing the scan-derived version identifier with the currently-stored version identifier; and where the currently-stored version identifier and the scan-derived version identifier concur, providing to the user an option to select updating of currently-stored content of the record; and in response to such a selection: enabling the user to scan at least part of the document and any annotations thereon to produce update image data; updating the currently-stored content of the record in dependence upon the update image data; and updating the version identifier of the record.
