ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a transmission document edition device that edits transmission documents described in markup languages, a received document processing device that receives and processes the transmission documents, and a communication document processing system that includes the transmission document edition device and the received document processing device.
2. Description of the Conventional Art
As a markup language, the SGML (Standard Generalized Markup Language) that is standardized by the ISO (International Organization for Standardization) has been used. The SGML is designed for document interchanges and is expressed as a group of elements called tags to describe the contents and the structure of a document. In the SGML, the contents of a document is precisely described. As a result, it is possible and easy to analyze such a document using a computer.
With the development of the Internet, the documents in the HTML (Hypertext Markup Language) that is based on the SGML have been interchanged. Such a document described in the HTML, i.e., an HTML document, is displayed using a Web browser that is a software for processing documents in the HTML. The HTML is standardized by the W3C (World Wide Web Consortium). The HTML Ver.3.2 has been standardized, and now standardization of the HTML Ver.4.0, which is the HTML for the next generation, is now being discussed. (The HTML is disclosed in detail on the home page with the URL (Uniform Resource Locator) “http://www.w3c.org/”.) The HTML Ver.4.0 enables the processing corresponding to an input operation using the Web browser to be described in the program called “script”. As a result, a wider variety of expression may be realized using the HTML Ver.4.0. For instance, it is possible to change the color of certain part of a document with the click of a mouse.
Conventionally, such an HTML document, which is transmitted via the Internet, was only received and displayed by personal computers, workstations, or the like. Recently, mobile communication terminals such as a portable remote terminal installed with a Web browser have begun to process such an HTML document.
Mobile communication terminals, however, have smaller display screens than personal computers, and the display areas are limited compared with those of personal computers. As a result, when displaying an HTML document that is originally created for personal computers or workstations, mobile communication terminals cannot display the HTML document as it is intended to be displayed. In order to solve the problem, it is necessary to create different HTML documents for different types of communication terminals.
As described above, it is possible to describe the processing corresponding to an input operation using the Web browser in an HTML document. Such an HTML document can include information on input units that mobile communication terminals are not equipped with. In this case, the operations using the input units may not be realized by mobile communication terminals. For instance, an operation input with a mouse may not be realized by pagers, which are equipped with no mouse.
SUMMARY OF THE INVENTION
It is accordingly an object of the present invention to provide a transmission document edition device that edits a transmission document from a general purpose document that is described in a markup language and a plurality of pieces of device information each piece of which includes information on the processing of the general purpose document for one specification of mobile communication terminal.
Another object of the present invention is to provide a transmission document edition device that simulates the display of a transmission document by a plurality of specifications of mobile communication terminal and the processing corresponding to a user input operation.
A further object of the present invention is to provide a received document processing device that enables a mobile communication terminal that receives a transmission document edited by the transmission document edition device to display the received transmission document in the most suitable manner and to perform processing corresponding to a user input operation.
Yet another object of the present invention is to provide a communication document processing system that changes a transmission document edited by the transmission document edition device into another transmission document for a specification of mobile communication terminal in order to reduce the load of the specification of mobile communication terminal and transmits the changed transmission document to the specification of mobile communication terminal.
The above-mentioned first object is achieved by a transmission document edition device that edits a transmission document to be transmitted to receiver devices of a plurality of specifications from a general purpose document described in a markup language, that may include: a document storage unit for storing the general purpose document described in the markup language; a device specification information storage unit for storing a plurality of pieces of device specification information, each piece of which a receiver device of a different specification refers to when processing the general purpose document according to marks in the markup language; and a transmission document creation unit for reading the general purpose document stored in the document storage unit and the plurality of pieces of device specification information stored in the device specification information storage unit and for creating the transmission document in which the general purpose document and the plurality of pieces of device specification information are related to each other.
It is possible for the transmission document edition device to create one transmission document that mobile communication terminals of the plurality of specifications may process. As a result, it is unnecessary to create a different transmission document for each specification of mobile communication terminal.
The first object may be achieved by the transmission document edition device, wherein a piece of device specification information includes information defining input and/or information defining output for a specification of receiver device, wherein information defining input includes each operation of a receiver device of a specification and a processing of the general purpose document accompanying an operation for each operation, and information defining output includes processing conditions for displaying the general purpose document in a manner suitable for the specification of receiver device, and the transmission document creation unit reads information defining input and/or information defining output for each of the plurality of specifications of receiver device from the device specification information storage unit, and has the read information defining input and/or the read information defining output be included in the transmission document in a manner in which information defining input and/or information defining output for a specification of receiver device is distinguishable.
It is possible for the transmission document edition device to create one transmission document that includes a plurality of pieces of device specification information for the plurality of specifications of mobile communication terminal. As a result, a mobile communication terminal may perform the same processing as processing the general purpose document in a transmission document created only for the specification of the mobile communication terminal. In addition, a mobile communication terminal may process the general purpose document using the operation key on the mobile communication terminal.
The first object may also be achieved by the transmission document edition device, wherein the transmission document creation unit describes an identifier showing a specification of receiver device using a first tag, information defining output using a second tag, and information defining input
