As shown in FIG. 7, a series of processing according to the present invention includes the following steps. The order of each step shown in FIG. 7 is an example, and the order may be changed as appropriate unless otherwise specified.

The storage means 11 stores information relating to the file that the user desires to convert, which has been transmitted to the server 1 by the upload means 21, in the database DB (step S101). The user displays the new registration screen 0w2 by pressing the new registration section 0w1a on the list display screen 0w1. The server 1 registers information such as the file name of the conversion source file uploaded using the upload unit 21 in the database DB. At this time, the server 1 issues a resource ID corresponding to the information related to the conversion source file. The resource ID is stored in the database DB in association with information related to the file, and the terminal device 2 may acquire the resource ID.

Based on the resource ID issued in step S101, the storage unit 11 associates the binary data of the conversion source file transmitted to the server 1 by the upload unit 21 with the resource ID and stores them in the database DB (step S102). . In this embodiment, when a large file is uploaded in step S102, the binary data is divided into multiple uploads to prevent communication errors.

The presenting means 12 presents a conversion tool capable of converting a conversion source file and a converted file, and item information associated with the conversion tool. The reception unit 13 designates a plurality of document conversion jobs using one or a plurality of conversion tools and designates the order of the document conversion jobs a plurality of times, based on pressing of the "Register" button on the reception unit 0w2d. Accept (step S103). If the user wishes to perform a different operation, he/she can cancel the upload of the conversion source file, the designation of the document conversion job, and the designation of the order by pressing the "Close" button.

The server 1 registers one document conversion job based on the conversion tool received by the receiving unit 13, the corresponding document conversion engine ID, and the issued resource ID (step S104). At this time, the server 1 issues a document conversion job ID, and stores the document conversion job ID in the database DB in association with the binary data of the conversion source file. In this embodiment, since the next document conversion job is executed using the post-conversion file stored in the database DB, the document conversion jobs are registered one by one in step S104.

The executing means 14 executes the file conversion based on the designated document conversion job and the order, and outputs the target post-conversion file (step S105). In this embodiment, the converted file output by the conversion executed in step S105 is stored in the database DB. In this embodiment, the execution unit 14 associates the status of file conversion to be executed based on the designated document conversion job with the document conversion job ID based on the conversion result.

The server 1 acquires the status of the document conversion job based on the issued document conversion job ID (step S106). If the status of the document conversion job is "waiting", the server 1 executes step S106 again after a predetermined arbitrary time. If the status of the document conversion job is "success" or "warning", the server 1 issues the resource ID of the post-conversion file, associates the resource ID with the binary data of the conversion source file, and saves it in the database DB. do. If the document conversion job status is "error", the server 1 terminates the series of processes.

Based on the resource ID issued in step S101, the terminal device 2 downloads the binary data of the post-conversion file according to the user's operation (step S107). Note that, in the present embodiment, it may be possible to download a post-conversion file even if it is a post-conversion file for which conversion has not been partially performed normally. Also, the converted file may be downloaded at any timing until the expiration date displayed in the list display section 0w2b after the conversion.

If the status of the document conversion job acquired in step S106 is "success" or "warning" and if the document conversion job designated in step S103 remains, the server 1 performs steps S104 to S107. repeat the process. At this time, in step S105, the document conversion job is executed using the post-conversion file output by executing the parent job. The server 1 terminates the series of processes when there is no conversion job for which the designation has been received in step S103.

In this embodiment, the storage unit 11 may register a new document conversion engine externally via the communication unit 106 before starting step S101.

According to the present invention, it is possible to provide a novel technique for a document processing system by activating the conversion tools in the order selected by the user.
