Abstract:
1. A document management system comprising: an electronic document editing unit configured to perform edit processing for an electronic document; a processing information obtaining unit configured to obtain edit processing information based on the edit processing performed by said electronic document editing unit; a management unit configured to manage the edited electronic document in association with generation information of the edited electronic document, the generation information including at least the edit processing information obtained by said processing information obtaining unit; a print processing unit configured to print the edited electronic document to a printed paper document, and to record the generation information in the printed paper document, wherein the management unit is further configured to update the generation information of the edited electronic document corresponding to the printed paper document by adding print processing information to the generation information, the print processing information being obtained from the print processing unit in response to the print processing by the print processing unit, and wherein the print processing unit records the updated generation information in the printed paper document that is outputted from the print processing unit; a copy processing unit configured to copy the printed paper document printed by the print processing unit into a copy destination paper document and to output the resulted copy destination paper document, wherein said copy processing unit is further configured to update the generation information recorded in the printed paper document by adding copy processing information obtained from said copy processing unit, and to record the updated generation information in the resulted copy destination paper document to be outputted from said copy processing unit; a scan processing unit configured to scan a paper document to obtain a scan image, the paper document being the printed paper document printed by said print processing unit or the copy destination paper document outputted by said copy processing unit, and to update the generation information recorded in the scanned paper document by adding scan processing information obtained from said scan processing unit, and to record the updated generation information to the scan image obtained by said scan processing unit; and a storage processing unit configured to update the generation information registered by said scan processing unit by adding storing processing information, and to store the scan image obtained by said scan processing unit with the generation information updated by said storage processing unit.
