Abstract: A method, system and computer program product for entering physical documents into a digital back-end system are provided. The system includes at least one scanner for scanning a document and generating an associated document image file, a server including an intermediate document store, connected to the scanner for storing a document image file together with a document identification in a document file, and at least one input device connected to the server for entering an attribute file. The attributable file contains a set of document attributes accompanied by a document identification. The server includes a merging unit for checking whether a document identification of one of the attribute files corresponds to a document identification of one of the document files and, if so, the merger unit links the set of attributes to this document file.
