Abstract: An information distribution system reduces the effort required to change an application in conjunction with changes in process content and changes in the receiver type or specifications while also accommodating broadcast processes. A style sheet database stores a plurality of output style sheets, which are information conversion rules including conditional expressions related to information distribution. An integrated device control service acquires output data and receiver information specifying the address of the receiver and the output style sheet corresponding to said receiver. When the output data satisfies the conditional expression contained in the output style sheet, the integrated device control service distributes converted output data, which is the output data converted based on the output style sheet, to the address of the receiver.

Abstract: Various kinds of value can be easily added to print data output from an existing application without modifying the existing application program. A value-adding method executes a process of adding value to print data output from an application on a computer that has one or more communication ports and executes a specific process by means of an application, and includes a data acquisition step of acquiring the print data at the operating system kernel layer before the print data is received at the communication port, and a data processing step that applies at the application layer a process of adding and/or deleting print content in the print data based on previously registered information, and outputs the data after processing to the specified communication port.

Abstract: The effort of changing an application in conjunction with a change in process content or change in the type or specifications of a receiver can be reduced, and a cooperative process involving a plurality of receivers without going through an application can be achieved.

In accordance with the success or failure of first conversion data distribution, the integrated device control service sends second conversion data, which is the output data converted according to the second style sheet, to the second receiver.

Abstract: A device control system does not require changing the application in conjunction with changes in process content or changes in the type or specifications of a device. A style sheet database stores a plurality of style sheets describing information conversion rules for XML documents. A communication interface acquires output data from an application, and acquires an XML document containing information specifying the target device to which the output data is output and an output style sheet. Based on the output style sheet, an XML document converter converts the XML document acquired from the communication interface to an XML document including device control information for the target device. A device-specific XML document input/output unit outputs the XML document acquired from the XML document converter to the device control service corresponding to the target device.
