Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a network for sharing information resources such as documents.
Regarding work systems.

[Prior Art] Conventionally, some network systems have a distributed processing type in which workstations having the ability to create and edit sentence data are distributed over a local area network having a host calculation mode. In such a network system, document data created and edited on a workstation is sent to the host computer, or resources (database) held by the host computer, such as document data, are sent to the workstation.

In this case, if the document format of the host computer and the document format of the workstation are exactly the same, document data can be exchanged simply by adding a communication means between them. However, if the document formats are different, it is necessary to convert the document format to match the document format of the workstation or host computer that receives the document data before sending it. For this reason, some workstations or host computers have a structure in which a document conversion device is added between the workstation and the communication means.

This allows the workstation or host computer on the receiving side to independently edit and utilize the received document data.

Note that document data includes text, geometric figures, and
Contains data corresponding to hemap figures and tables.

[Problems to be Solved by the Invention] By the way, in the conventional network system described above, when the host computer sends document data to the workstation, it sends the data necessary for data processing (for example, character code, etc.) and the workstation. The station transmits data necessary for editing document data, that is, data for beautifully representing the document format (for example, data indicating document attributes, ie, data indicating font, font size, etc.).

However, sentence 1 in the document data as described above
The data used to express Expression 1 beautifully includes a lot of data that is not subject to data processing by a host computer whose purpose is data processing. Therefore, when transmitting document data, the host computer must transmit nested data, which requires a lot of processing time for transmitting document data.

Therefore, in the above-mentioned conventional network system, there is a drawback that the host computer cannot effectively utilize the resources held by the host computer due to the long time dedicated to the document data transmission process. This method has the disadvantage that it is not possible to efficiently exchange document data between the computer and the workstation.

The present invention solves the above-mentioned drawbacks and shortens the time dedicated to the document data transmission process by the host computer.
It is an object of the present invention to provide a network system that can effectively utilize resources held by a host computer and improve the efficiency of exchanging document data between a host computer and a workstation.

(Means and Effects for Solving the Problems) The present invention provides a first means for processing document data, and predetermined data regarding the document data, for example, at least some of the attributes of the document. a second means for creating/editing the document data; and an adding means for receiving the document data transmitted from the first means; However, if data corresponding to the specific data (data indicating at least some of the attributes of the document) specified by the specification means is not added to this document data, the specified data is added to the document data. (data indicating at least some of the attributes of the document) and transmits the data to the second means; If the transmitted document data lacks attribute data, the missing attribute data is added to the document data and sent to the second means.

FIG. 3 shows a block diagram of a data conversion device 6 that is used in a network system according to the present invention. The data conversion device 6 includes a complementary data specifying section 30 and a data complementing section 31. The complementary data specifying unit 30 has a memory 32 that stores an editable text format file.

As shown in Figure 4, the above-mentioned editable text format file contains data for beautifully expressing the sentence mW expression, that is, font attribute data items and paragraph attributes that have elements for specifying document attribute data. It consists of data items, page attribute data items, etc. Each element corresponding to each of these attribute data items has data added thereto for specifying the attribute data, that is, supplementary data for supplementing the attribute data missing from the input attribute data.

For example, in the font attribute data item, as shown in Figure 4, the character size element includes size S1, S
Data for specifying attribute data such as 2, S3, etc. is added, and data for specifying attribute data such as Fl, F2, F3, etc. is added to the font element.

Data for specifying each attribute data added to the character size element and the font element is specified by the document editing device 7. The data specified by the document editing device 7 is registered in the file as complementary data. The complementary data registered in this manner is sent to the data complementing section 31, as shown in FIG.

On the other hand, the data complementation section 31 has an area 33a for storing an input file in which attribute data of a document sent from the host computer 1 is registered, and an area 33b for storing complementation data input from the complementation data specifying section 30. , and an output file storage area 33c in which attribute data of the document stored in the area 33a and supplementary data stored in the area 33b are registered.

Next, the operation of the network system described above will be explained based on FIGS. 5 and 6. First, the operator specifies the host computer 1 using the document editing device 7, and if the operator wants to receive desired document data from this host computer 1, the operator specifies the host computer 1 using the keyboard 11 or the mouse 1.
2 to specify host computer 1,
Specify the desired document data. Furthermore, keyboard 11
Alternatively, the user specifies complementary data for each element of the attribute data item of the document data displayed on the display device 19 by operating the mouse 12 in a predetermined manner.

For example, when specifying supplementary data regarding font attribute data, the operator operates the keyboard 11 or mouse 12 of the document editing device 7 in a predetermined manner to specify ``Character size = 81'' and Paragraph font = F1''. . The complementary data instructed in this way is sent to the data conversion device @6.

On the other hand, the host computer 1 designated by the document editing system @7 sends desired document data instructed by the operator. The document data sent from the host computer 1 is input to the data conversion device 6 via the communication device 2, three communication lines, and the communication server.

The data conversion device 6 sends the complementary data input from the document editing device 7 to the complementary data specifying section 30, and also transmits the document data input via the communication server to the data complementing section 3.
Send to 1.

The complementary data specifying unit 30 registers the input complementary data in the memory 32 and sends the complementary data registered in the memory 32 to the data complementing unit 31. The data complementation unit 31 develops the complementation data input from the complementation data specification unit 30 as a table in the area 33b of the memory 34 (
Step 2゜O). For example, the area 33b of the memory 34 stores the complementary data 1 sent from the complementary data specifying section 30.
oO1 That is, "Character size = S1", "Font = F1"
” case data is registered.

The data complementing unit 31 also specifies an input file in which attribute data of a desired document sent from the host computer 1 is registered (step 201), and also specifies an output file corresponding to the specified input file. It is determined whether predetermined data has been populated (step 202).

If writing of the predetermined data to the output file is not completed in step 202, the data complementing unit 31 extracts the attribute data from the input file in step 203>, and further extracts the attribute data extracted from the input file. It is determined whether there is data corresponding to the complementary data stored in the area 33b of the memory 34 (step 204). In step 204, if the data corresponding to the complementary data does not exist, the data complementing unit 31 stores the complementary data corresponding to the data that did not exist in the extracted attribute data in the area 33b of the memory 34. The data is extracted from among the supplementary data that has been provided (step 205).

Further, in step 205, the data complementing unit 31
The complementary data taken out from the area 33b of the memory 34 is inserted into the output file (steps 206 and 207). Further, in step 204, the data complementation unit 31 determines that if data corresponding to the complementation data stored in the area 33b of the memory 34 exists in the attribute data, or if data corresponding to the complementation data stored in the area 33b of the memory 34 exists, If the data corresponds to complementary data other than complementary data, the existing data is included in the output file.

For example, focusing only on the font attribute of the attribute data of document data, the complementary data 100 stored in the area 33b of the memory 34 is the attribute data of "font = F1" and [font size = S1]. In addition, if the data 102 extracted from the input file is the attribute data content of "Character position = P1", the data complementing unit 3
1 determines whether data corresponding to each attribute data content of the complementary data 100 is added to the data 102.

In this case, the data complementing unit 31 adds “
It is determined that data corresponding to the attribute data contents of font-“1” and “font size-81J” is not added, and the attribute data contents are written in the area 33c of the memory 34. Also, the data complementing unit 31 determines that “Character position = P1” of data 102 corresponds to complementary data other than the above complementary data 100, and determines that “Character position = P1” of data 102
” is written in the area 33c of the memory 34.

" As a result, the area 33G of the memory 34 has the font="1
”, “Character size=S1”, and “Character position=P1” are stored.

Note that the data complementation unit 31 performs the same operations as described above regarding the font attributes regarding the paragraph attributes and page attributes of the document data.

By the way, the data complementing unit 31 performs step 20 described above.
When step 7 is completed, the process returns to step 202 and executes the subsequent steps. In step 202, if writing of the specified data to the output file is completed, the data written to the output file is output. do.

The data output from the f-event complement section 31 is input to the document editing device 7 via the Ethernet and an Ethernet transceiver, and is subjected to editing processing and the like by the document editing device 7.

According to the embodiment described above, even if the document data sent from the host I/it 11 that performs data processing lacks the attribute data of the document, the document editing device 7
The document data supplemented with the missing attribute data will be input to .

[Effect of the Invention] According to the present invention, when all the attribute data of the document is not added to the document data transmitted from the first means for data processing, the document converting means adds the missing attribute data. Since it is added to the document data and sent to the second means for creating and editing the document, the first means can significantly reduce the amount of attribute data in the document, and the document data is sent to the second means. Provided is a network system that can shorten the dedicated time for transmission processing for document data when transmitting document data, and can improve the efficiency of document data exchange between a first means and a second means. can.
