Abstract

PROBLEM TO BE SOLVED: To provide a method and a system capable of using styles of definitions different each other. SOLUTION: In the system capable of using the plural different styles of definitions with respect to one semantic data, a data preparing person checks whether the using style definition is a style definition of which the use is approved by the reliable third body or not (step 11). When it is the approved style definition, a hash value thereof is added to the semantic data (step 14). A receiver checks whether the using style definition is the style definition of which the use is approved by the reliable third body or not (step 21). When it is the style definition of which the use is approved (step 23), processing is continued, and the processing is terminated when it is not the approved style definition (step 22).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display method which allows the use of different style definitions for one semantic data, and more particularly to a method for displaying semantic data when different displays are made by using different style definitions. The present invention relates to a method and a system for managing a style definition in which various problems such as easy misunderstanding of contents are unlikely to occur.

[0002]

2. Description of the Related Art In recent years, with the spread of the Internet and the like, importance has been placed on data interchangeability. The data format suitable for exchange is XML (eXtensible Markup Languag
e) or SGML (Standard Generalized Markup Language)
Etc., and are still used at the business level. In particular, XML is actively being used as a standard format for electronic applications that is expected to spread in the future, and can be said to be a data format that can be used in various situations.

[0003] In data exchange, it is important to identify a sender and a receiver and to assure that the data has not been tampered with. In particular, for electronic data, measures such as digital signature and super hash of the data have been taken. In many cases, these measures make it possible to exchange data without impairing the meaning of the data.

[0004] Data originally has two aspects: "meaning" and "style". “Meaning” refers to the meaning (value) of the data, and “style” refers to the method of expressing the meaning (value). For example, when entering data representing the amount of money in a ledger or other ledger, the content representing the amount of money is semantic data, and the rules such as typing ", (comma)" every three digits and aligning to the right are styles. Is equivalent to In the above-mentioned XML and SGML, it is possible to apply a plurality of different “styles” to one “meaning”.

For this reason, for example, SGML is used similarly to XML.
HTML (Hyper Text Markup La)
For example, when the same HTML file is displayed by different browser applications, the display may be different. Since the display differs depending on the browser application and the display preference differs depending on the user, the user can select a browser application that performs a display suitable for his / her preference. In addition to the standard styles provided by browser applications,
It is also possible to apply a style uniquely defined by the provider of the L file. The same can be said for the case where an application that can handle XML spreads in the future.

By using a flexible data format in which "meaning" and "style" are separated,
For example, there may be a case where the person providing "meaning" and the person providing "style" are not the same. For example, it is also possible for government organizations to provide a "meaning" format for electronic applications to government organizations, and to provide multiple private companies with a "style" format used when creating or browsing the application data. is there. By realizing such operations, private companies are expected to develop and provide more convenient "style" formats, and residents will always be able to use the more convenient "style" format. It is possible to receive.

[0007] Such cases are described in XML, SGML, HTML.
However, the present invention can be applied to, for example, the relationship between characters and character fonts.

[0008]

When such a conventional technique is used, even if the "meaning" of the data is the same, the display result may be different depending on the "style" used, which may cause confusion. . For example, in the case of an account book, if a style definition that displays “1,000,000” and a style definition that displays “1,000,000” is used for data having a “meaning” of “1,000,000”, the contents are examined. It is difficult for a person to intuitively understand that they represent the same contents.

[0009] For example, when such a data format is used for an electronic application to an administrative organization, an application for administrative use may state that "when selecting one of two selection items, one is circled and the other is a double line. However, if the style definition used by the applicant does not have this function, correct display is not possible and this may be a problem. More fatally, for example, when considering an electronic application to an administrative agency, the style definition used by residents may be created by a malicious third party, causing a problem without legitimate display There is also.

As a means for avoiding the occurrence of such a problem, there is a method of embedding a usable style format in the semantic data in advance without making semantic data and style separable. However, in this method, when there are a large number of available style formats, the data size becomes large, and there is a problem that the data format is not suitable for data exchange. As a solution to this problem,
In addition, there is a method that does not allow the use of different styles and determines the only available style format. However, it is possible to improve the user's convenience by applying multiple style formats to the same semantic data. ", Which impairs the maximum advantage of a data format in which" meaning "and" style "are separated.

It is an object of the present invention to provide a method and system that allows the use of different style definitions.

It is another object of the present invention to provide a method and system for supporting the use of style definitions that do not impair the meaning in a method and system capable of using different style definitions.

It is yet another object of the present invention to provide a method and system that allows the use of different style definitions to determine the liability when a style definition that is meaningless is used. Is to do.

[0014]

According to the present invention, in order to enable the use of a plurality of different style definitions, an item indicating "style definition permitted to be used" is provided in the semantic data.
In the item, a unique value that can specify each style definition practically and does not significantly increase the size of the semantic data is embedded. Such a unique value may be, for example, a combination of a style definition name and a hash value. However, it is desirable that the style definition name also includes the provider name and the creation date and time.

Further, in the present invention, in order to support the use of style definitions that do not impair the meaning, the examination organization examines the contents of each style definition and determines that the style definition that can be displayed without impairing the meaning is determined. For authorization. An example of the process for representing the authorization is an electronic signature applied using a secret key of an inspection organization. In the present invention, an item indicating “used style definition” is entered in the semantic data in order to clarify the responsibility when a style definition whose meaning is impaired is used.

Furthermore, an electronic signature or the like is applied to the semantic data in a state where items indicating “usable style definition” and “used style definition” are entered in the semantic data, and “semantic data contents”, “usable style definition” Ensure the completeness of "style definition" and "used style definition".

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a method and system for managing the use of different style definitions in the present invention will be described in detail with reference to the drawings.

FIGS. 1-4 illustrate an embodiment of a method and system for managing the use of different style definitions in the present invention.

FIG. 1 is a flow chart showing an embodiment relating to a processing procedure of an applicant and a receiver when the present invention is applied to application data in an electronic application. FIG.
5 is a flowchart showing an embodiment relating to a processing procedure of a style definition provider and a style definition examination organization. FIG. 3 is a block diagram showing a system configuration when the present invention is applied to application data in an electronic application. 4 and 5 show a template for creating data by applying the present invention and an example of created data.

In FIG. 3, a style definition provider 40 creates a style definition 41 and distributes the style definition 41 to a data creation sender 45. Similarly, style definition provider 4
2 creates a style definition 43 and provides the data reception examiner 47 with the style definition 43. Before the style definitions 41 and 43 are provided to the user, they need to be reviewed by the style definition reviewing agency 44 and obtained permission.

The data creation sender 45 has the style definition 41
Is used to create the semantic data 46. Semantic data 46
Has a format like a template 50 shown in FIG. The template 50 describes style definition information 51 that can be used for creating and browsing the semantic data. Using the style definition described in the usable style definition information 51, the semantic data 60 is created. The style definition information 61 used is described in the semantic data 60,
By writing in the signature section 62 a signature value obtained by digitally signing the entire semantic data 60 with the secret key of the data creation sender 45, the integrity of the semantic data 60 is guaranteed.

The data creation sender sends the created meaning data 46 to the data reception examiner 47. The data reception examiner 47 obtains semantic data 48 corresponding to a copy of the semantic data 46. The data reception examiner 47 browses the semantic data 48 using the style 43 described in the usable style definition information 51 described in the semantic data 48. At this time, the data creation sender 45 and the data reception examiner 47
Have the same contents but may be different in terms of display. This is because the data creation sender 45 uses the style definition 41 and the data reception examiner 47 uses the style definition 43, and both use different style definitions. However, since the style definition examination agency 44 guarantees that the display is not likely to cause a problem due to the difference between the displays, the problem due to the difference in the display is unlikely to occur. Further, even if any problem due to the style definition occurs, it is possible to specify that the responsibility is located in any of the style definition provider 40, the style definition provider 42, and the style definition examination body 44. In addition, problems such as a problem that cannot be dealt with due to a prior agreement are unlikely to occur.

Next, the operation of FIG. 3 will be described with reference to the flowcharts of FIGS. First, the operation of the style definition providers 40 and 42 of FIG. 3 will be described based on the flowchart of FIG. First, the style definition provider 40
And create style definitions 41 and 43 (step 30). The created style definition is digitally signed with the secret keys of the style definers 40 and 42 (step 31), and the creator of the style definition is identified. Next, the style definition providers 40 and 42 send the created style definitions 41 and 43 to the style definition examination organization 44 (step 32). The style definition examination body 44 examines the content of the received style definition (step 33),
When it is determined that the style definition may cause a display that impairs the content, the style definition provider is returned to the style definition provider, and the style definition provider corrects the style definition and repeats the processing from step 30 onward. If it is determined that there is no danger that the style definition will impair the contents, an electronic signature is performed using the secret key of the style definition examination body (step 34), and the style definition examination body 44 is responsible for the style definition. To reveal. Finally, the style definition examination body 44
The style definitions 41 and 43 with the electronic signature of
Returned to the style definition providers 40 and 42, the style definition providers 40 and 42
Acknowledges the content, and the creator has a clear style definition 41
And 43 are obtained.

Next, based on the flowchart of FIG. 1, the data creation sender 45 and the data reception examiner 47 of FIG.
Will be described. First, the data creation sender 45 obtains the style definition 41 (step 10). Next, the data creator / sender 45 determines, based on the available style information 51 described in the data format 50, whether the acquired style definition 41 is permitted to be used (step 11). If the obtained style definition 41 is not approved for use, the display is terminated without creating data because there is a possibility that the display may be damaged (step 12). If the style definition is approved, the application data is created using the style definition 41 (step 13). After the application data is created, the used style name (name that can identify 41) and its hash value are described in the item 61 describing the used style definition information in the application data 60 (step 1).
4). Next, an electronic signature is performed with the secret key of the data creation sender 45 to guarantee the integrity of the created application data including the description of the used style definition information and to identify the creator (step 15). The signature information is described in the signature section 62 to create the signature data 46. Finally, the data creation sender 45 sends the signature data 46 to the data reception examiner 47 (step 16).

On the other hand, the data reception examiner 47 receives the signature data 48 corresponding to the copy of the signature data 46 (step 17), and verifies the signature of the signature data (step 1).
8). If the signature is invalid as a result of the verification, the integrity of the signature data 46 is not guaranteed or the creator is not clear, so the process ends without performing the subsequent processing (step 19). If the signature is valid, the style definition 43 is obtained (step 20), and the processing moves to the subsequent processing. The data reception examiner who has obtained the style definition 43 determines whether or not the style is permitted to use the style definition 43 based on the available style information 51 described in the signature data 48 (step 21). If the style is not approved for use, there is a possibility that the display may be damaged, so that the processing is terminated without performing the subsequent processing such as data content examination (step 22). If the style is approved for use, the data is received (step 2).
3), proceed to subsequent processing such as content examination.

Next, an embodiment in which the present invention is applied to electronic filing of income tax will be described with reference to FIGS. First, the filer obtains the electronic filing data format from the relevant tax office or an organization, a company, or an individual recognized by the relevant tax office. In this electronic report data format, usable style definition information is described. In the present embodiment, “A.xsl”, “Bx
It is assumed that a description that allows the use of three XSL files called "sl" and "C.xsl" is described. Next, the filer obtains the style definition required for preparing and viewing the electronic report from each tax office or private company. The filer creates electronic report data 70 by using the obtained style definition.

FIGS. 7 and 8 show examples in which the display format differs depending on the style definition used. Both figures show examples of screens provided by a computer program displayed for creating or browsing electronic filing data. It is assumed that one display example 80 of the electronic report data 70 shown in FIG. 7 is displayed using one of the three types of style definitions shown in the available style definition information 71. FIG.
The display example 90 shown in FIG.
It is assumed that the display is made using the style definition that is not shown in. In both display examples (80 and 90), the information indicating the total amount 72 of the declared amounts is the same
599180. However, in display example 80, a display 84 of the total amount of income in units of yen is made at the upper right of the screen, separated by commas every three digits. A display 94 of the total declared amount as a unit is provided. Also, since there are many display items of electronic declaration data, it is difficult to fit all of them on one screen.
In the display example 90, only the upper area 92 of the boundary 91 is displayed on the first display screen. The lower region 83 of the boundary line 81 and the lower region 93 of the boundary line 91 are not displayed unless the screen display scroll function of the computer program is used.

In this embodiment, the filer who uses the style definition for display as in the display example 80 can easily check the total amount of the filed, so that it is easy to make mistakes such as the filed amount being too high (or too low). Is likely to be noticed, and a decrease in underreporting is expected. On the other hand, a filer who uses a style definition that displays as shown in display example 90 cannot easily check the total amount of the filed, and there is no three-digit comma delimiter commonly used when displaying the amount Since the unit is displayed as K yen, an error in the declared amount is likely to occur, and the frequency of requesting a revised declaration due to underreporting or the like increases.

Further, in the case of using a style definition whose use for display as shown in FIG. 9 is not permitted, the declared amount 104 is displayed at the upper right of the screen and a comma separated by three digits is displayed. Since 104 is displayed less than the declared amount 72 on the semantic data, the reporter has a high risk of underreporting.

An embodiment in which the present invention is applied to a facility use information disclosure system provided to local residents by local governments will be described with reference to FIGS. 10 to 12.

In City A, information such as the location of public facilities is electronically provided to residents. In this system, A
City officials create information about public facilities as XML data and provide browsing services to residents using the Web. At this time, the style definition for displaying the XML data can be selected from several types, and the style definition used by the inhabitants can be selected.

Facility information 11 provided by City A shown in FIG.
In 0, available style information 111 is described. In the facility information 110, a description 112 regarding the change of the location of the facility is described, and image information 113 indicating the location before and after the change is also described.

FIGS. 11 and 12 show examples in which the display format differs depending on the style definition used. In both figures, it is assumed that the screen represents an example of a screen provided by a computer program displayed for browsing the facility information, or the screen is printed on paper. One display example 1 of facility information 110 shown in FIG. 11
Reference numeral 20 denotes that one of the three types of style definitions shown in the available style definition information 111 is used for display. Further, it is assumed that the display example 130 shown in FIG. 12 is displayed using a style definition not shown in the available style definition information 111.

In display example 120, image information 1 indicating the location
13 is a style definition for displaying in the order of description 112 and displaying an image below the text. Therefore, the correspondence between the expression “in the figure below” and the image actually displayed is correctly displayed. 124 is displayed. On the other hand, the style definition used in the display example 130 is a style definition for optimizing the space, and the display position of the description and the image is shifted. A new location image 134 is displayed immediately to the right of the expression 131 representing the old location, and a 132 is displayed immediately below the expression 133 representing the new location. The description and the image are displayed interchangeably.

In this embodiment, a resident using the style definition displaying the display example 120 can know the location information of the facility correctly, but a resident using the style definition displaying the display example 130 can display the location information of the facility. I can't get the information right. Therefore, there is a possibility that a problem may occur such that the inhabitants cannot receive the administrative services available in the facility.

[0036]

As described above, according to the present invention, the style definition provider guarantees the completeness of the contents of the style definition by using a technique such as an electronic signature and identifies the creator. The style definition examination body uses technology such as electronic signature to assure the completeness of the content of the style definition only for the style definition approved by the style definition examination body, and performs the process of identifying the authorizer. The person who creates and browses the data determines whether to use the distributed style definition based on the style definition information that permits use described in the data, and describes the used style definition information in the data, A method in which the user uses digital signatures or other techniques to ensure the integrity of the data content and to perform a process to identify the user, resulting in a display that could damage the content. The use of yl defined with prevented, such style definitions it becomes possible problem by being used to reveal where the responsibility upon arising.
