The document processing operation in the document processing system 100 according to the present embodiment will be described based on the form information and linking information generation processing related to the generation of the construction cost breakdown document in which the respective systems are linked as described above.

The document processing system 100 uses the processing function of the meta-information generating means 110 to store the linking information for the PDF file according to the flowchart shown in FIG. 3 and read the linking information from the PDF file according to the flowchart shown in FIG. Execute the process.

Storing processing of linking information for a PDF file in this embodiment will be described with reference to FIG. This process is executed in the terminal device 10 in accordance with the creation of the construction cost breakdown described above (see FIGS. 5 and 7) and the execution of the subsequent revision of the construction cost breakdown.

In the terminal device 10, in accordance with the input of document information from the design and integration system (see FIG. 7A), the document generation unit 102 of the document processing system 100 generates a construction work content as shown on the right side of FIG. 6, for example. A cost breakdown is generated.

As shown in FIG.

Next, in the meta-information generating means 110, the meta-information generating unit 112 reads out the tying information from the tying information DB 130 (step S11), and generates meta-information of the tying information from the tying information (step S12).

Subsequently, the encryption processing unit 114 encrypts the meta information generated by the meta information generating unit 112 using the encryption key stored in the encryption key storage unit 113 (step S13).

Next, the encrypted meta information storage unit 115 outputs the encrypted meta information encrypted by the encryption processing unit 114 to the file generation unit 103, and converts the encrypted meta information into the PDF file generated by the file generation unit 103. In cooperation with the file generation unit 103, a process of storing (embedding) the file is executed (step S14).

Before receiving the encrypted meta information output from the encrypted meta information storage unit 115, the file generation unit 103 converts the display layout information and the display data information (document information corresponding to the construction cost breakdown) to the form generation unit 102. Form display information generated based on is received, and a PDF file consisting of only the form is generated.

When the encrypted meta information output from the encrypted meta information storage unit 115 is received in this state, the file generation unit 103 adds the encrypted meta information to the display data information, that is, the document information corresponding to the construction cost breakdown.

As a result, in this embodiment, both the document information and the linking information of the construction cost breakdown document generated by the terminal device 10 can be viewed by the PDF viewer equipped with the meta information generation means 110 (see FIG. 8 ( a)), and a PDF viewer not equipped with the meta-information generating means 110 can only browse document information (see FIG. 8A).

After the PDF file is generated in step S14, for example, the CPU 11 outputs the PDF file based on the output instruction from the input device 15, and ends the series of linking information storage processing in FIG. As an output form at this time, for example, a process of storing a PDF file in the server device 20 can be mentioned.

The work cost breakdown document that constitutes the PDF file output in step S15 may need to be revised, for example, the work type and quantity during the procedure up to ordering. In this case, in the document processing system 100 according to the present embodiment, the meta information generating means 110 reads the output PDF file, extracts the document information and the linking information, re-edits the document information, and At the same time, the linking information can also be updated.

FIG. Specifically, the PDF file in which the encrypted meta information is embedded is read by the file reading unit 104 (step S21). In the present invention, the file reader 104 constitutes a file reader.

Next, the encrypted meta information reading unit 116 determines whether or not there is encrypted meta information read by the file reading unit 104 from the loaded PDF file (step S22). Here, if it is determined that there is no encrypted meta information (NO in step S22), the process is terminated.

On the other hand, if it is determined that there is encrypted meta information (YES in step S22), encrypted meta information reading unit 116 reads the encrypted meta information read by file reading unit 104 (step S23). .

Subsequently, the decryption processing unit 118 receives the encrypted meta information from the encrypted meta information reading unit 116, and decrypts the encrypted meta information using the decryption key stored in the decryption key storage unit 117 ( step S24).

Next, the meta information reading unit 119 reads the meta information decrypted in step S24 (step S25). Further, the information search unit 105 extracts the linking information from the decrypted meta information (step S26), and ends the series of linking information read processing in FIG. In the present invention, the information search unit 105 constitutes a tied information extraction unit.
