Conceptual Metadata Schema Model of Document Records in e-Government

A format pattern carried on a format transparency is photoelectrically converted into an electric signal. The electric signal representing the format pattern is inputted into an "exclusive-or" circuit together with a character pattern signal representing output information of a computer. The output of the "exclusive-or" circuit controls an on-off modulator which modulates a laser beam for recording the output information of the computer. The modulated laser beam is deflected by a beam scanner to scan a photosensitive or heat sensitive film to record thereon the format pattern together with the computer output information.
