Abstract

PROBLEM TO BE SOLVED: To solve the problem that the high management cost is needed to update component data and the cost needed for the update management of the component data becomes high since data such as document data or component data increase in number and the number of files also increases as a result. SOLUTION: A component extracting means 6 reads a data file out of a data storage means 2, inspects whether or not component data are described, and outputs and registers the contents as component data in a component storage means 7 together with ID information when the component data are described. According to ID information retrieved by a component retrieval means 3, a component storage means 7 retrieves component data which has matching ID information and outputs the retrieval result as reference component data to a data update means 4. The data update means 4 takes in the corresponding reference component data from the component storage means 7 according to the ID information and embeds them in a place where the component data of the document data from the component retrieval means 3 are referred to generate a complete document.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data presentation system, and more particularly to a data presentation system for presenting document data to be taken in by referring to an external component document (component data).

[0002]

2. Description of the Related Art When creating large-scale document data,
There is a method in which a part of a document is divided and described as a plurality of part documents, and a part document (part data) is fetched and embedded in a reference source document to form a complete document. There is also a method of configuring a hypertext document which is connected so as to refer to a component document (component data) by link designation. By adopting such a method,
There is an advantage that a large-scale document can be divided into small units and managed, and further, the document can be made into parts and reused. In order to describe such a compound document, HTML (hyper Text Markup Language) is used.
e), SGML (Standard Generalized Markup Languag)
e) and markup languages such as XML (eXtensible Markup Language) are currently widely used.

[0003] Further, objects to be described as documents are not limited to characters and text data. For example, VRML (Virtual Reality Modeling Language, ISO) which is a three-dimensional space description language.
/ IEC14772-1), the shape of a three-dimensional object,
A document that handles various types of information such as colors, patterns, arrangements, and animations as components can be described. Also,
SMIL (Sync is a language standard that handles multimedia information with time axis information such as video and audio as component data.
hronized Multimedia Integration Language) is also known.

In the above language, markup is described by an object reference or a tag declaration of a link that specifies an external document to be embedded in the document. The written document is presented to the user by dedicated viewing software (browser). For example, in the case of a Web page described in HTML,
An HTML file can be created for each chapter of the document, and the reference HTML document can be embedded in the document by referencing these documents with object tag declarations. The HTML file created in this manner can be browsed by a user using a Web browser program.

[0005] A data presentation system that extracts and classifies frequent keywords from a large-scale text, creates an index, and displays a document number and a document title corresponding to the created index is also known. (Japanese Patent Laid-Open No. Hei 10-143517: title of document "document creation device").

According to this conventional data presentation system,
Classifying means for classifying a set of documents into one or more stages according to similarity in order to shorten the time required to reach a document requested by a user by documenting a search course in advance, A configuration including a classification result holding unit capable of holding a multi-stage classification of a document set, and a document generation unit for recording a classification result in order from a high-order classification and generating a document capable of following the progress of the fine classification up to the group The file is stored in a large-scale database, and the entire file is managed by an ID number.

Further, a hypertext document acquired by a network is stored in a local storage, and if a hypertext document to be referred to is already stored locally, that document is substituted (cached), and a file of the file is stored in the local storage of the hypertext. Serialization (combine into one document)
A data presentation system for performing the following is also known (Japanese Patent Laid-Open No. 10-307746: title of invention "Hypertext processing device and medium recording hypertext processing device control program").

According to the conventional data presentation system,
When the file control unit receives a save instruction from the input unit, the plurality of hypertext data are stored in a file of the hypertext data storage unit while maintaining the link relationship, and when the read instruction is received from the input unit, the plurality of hypertext data are saved. By reading the plurality of hypertext data from the hyperbar text data storage unit while maintaining the link relation and outputting the hypertext data to the display control unit, the hypertext data obtained via the network can be transferred between the hypertext data. The hypertext data stored in the file can be read out without maintaining the link relation and displayed on the display unit while maintaining the link relation, and can be stored in one file while maintaining the link relation.

[0009]

However, a part of a document is divided and described as a plurality of part documents, and a part document (part data) is fetched and embedded in a reference source document to thereby form a complete document. In a conventional data presentation system that is configured or configured to form a hypertext document connected so as to refer to a part document (part data) by link designation, the number of data such as document data or part data is large. As a result, the number of files also increases correspondingly, which causes a problem that a high management cost is required especially when updating the component data. The reason is that data is created as individual files in one-to-one correspondence.

[0010] Further, in the above-described conventional data presentation system, the cost required for managing the update of the component data is high. The reason is that, in the conventional method, the reference markup to the component data is directly specified by a file name or the like. Therefore, when updating a certain component data file to another data file, the corresponding This is because the contents of the markup description must be updated at the same time, resulting in a high work cost.

In the conventional method, in order to avoid updating the markup in the reference source document, it is possible to update only the content without changing the file name of the component data. However, in this case, a separate mechanism for individually managing a plurality of component data having the same file name and different contents is required, which results in enormous costs in building and operating the system.

In the conventional data presentation system described above, a document presentation environment or browsing conditions such as date and time of browsing, personal attributes such as user's gender and age, geographical conditions such as a place where browsing is performed, and display characteristics of a terminal device. It is difficult to change the contents and structure of the document according to the difference so as to obtain the optimum document. The reason is that the reference markup in the reference source document is fixedly described by the file name, and there is no means to adaptively and dynamically update the reference relationship according to the document browsing environment or browsing conditions. It is.

In the conventional data presentation system described in Japanese Patent Application Laid-Open No. H10-143517, the file is stored in a large-scale text database, and the entire file is managed by an ID number. Part cannot be treated as a part, and there is no reference / non-reference relationship between documents. Also, in this conventional data presentation system, the document that is the final output is a “document list” that is extracted from a large-scale text database and that corresponds to a specific keyword. Is not explicitly specified, but is dynamically generated as a result of a predetermined document classification program, and cannot be controlled by the user.

Further, in the conventional data presentation system described above, only the parameter adjustment of the classification program is performed, it is not possible to participate in the configuration of the output document, and the update of the reference relation is performed under the condition ( Time conditions, conditions based on attributes, etc.).

Furthermore, in the conventional data presentation system described in Japanese Patent Laid-Open No. Hei 10-307746, a reference relationship between documents is defined by a hypertext. The linked reference document can only be newly displayed on the browser, and cannot be applied to a method of embedding the reference document in the document to obtain a compound document having consistency as a whole.

In the above-described conventional data presentation system, the content of the output document itself does not change only by changing the reference destination via the network or local, and the content of the generated document cannot be changed. However, since a part of a file cannot be handled as a part, there is a problem that a file containing a plurality of parts cannot be used in one file. Further, in the above-described conventional data presentation system, switching of reference cannot be designated by data. Further, in the conventional data presentation system described in Japanese Patent Laid-Open No. Hei 10-307746, data constituting a hypertext can be serialized. However, since this is an intermediate file for data management, the serialized document Some of them cannot be updated.

The present invention has been made in view of the above points,
An object of the present invention is to provide a data presentation system capable of describing a combination of files and data in a flexible manner so that an arbitrary number of component data and document data can be described in an arbitrary file.

It is another object of the present invention to provide a data presentation system with low management cost of document data.

Another object of the present invention is to provide a data presentation system which can update component data from the outside without updating a reference portion to the component data in the document data, and which has a low document data update cost. To provide.

Still another object of the present invention is to provide a data presentation system capable of generating and presenting an optimum document by changing a reference to part data in document data according to an external environment or a user attribute. To provide.

Next, embodiments of the present invention will be described with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram of a data presentation system according to a first embodiment of the present invention. In the figure, a data input means 1 according to the first embodiment is shown in FIG.
A data storage unit 2, a component search unit 3, a data update unit 4, a data presentation unit 5, a component extraction unit 6,
And a component storage means 7.

The data input means 1 includes an internal storage device (memory; random access memory) connected to a computer (central processing unit; processor, data processing device) and an external storage device (magnetic disk, floppy (registered trademark)). Disk, CD-ROM, DVD-ROM, etc.)
Alternatively, input data is fetched through a telecommunication line such as the Internet.

The data storage means 2 stores the input data taken in by the data input means 1 as a data file. The component extracting means 6 reads the data file stored in the data storage means 2, checks whether or not the component data is described, and if the component data is described,
It is registered in the part storage means 7 as part data.

The component storage means 7 stores the component data extracted by the component extraction means 6 and searches for the component data upon receiving an inquiry using ID information described later as a search key. Output as

The component search means 3 reads the data file stored in the data storage means 2, searches whether or not document data is described, and outputs the document data to the data updating means 4 if the document data is described. I do. Further, the component search unit 3 checks whether or not a reference to external component data is described in the document data. as a result,
If there is a description of reference to external component data, the ID information of the referenced component data is output to the component storage means 7 as a search key.

The data updating means 4 generates a complete compound document incorporating external parts based on the document data from the parts searching means 3 and the reference parts data from the parts storing means 7 and outputs the same as updated document data. Data presentation means 5
Presents the updated document data output from the data updating means 4 to the user.

Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG. As the input data taken in from the data input means 1, data inputted directly into an internal storage device by a user's operation of a keyboard or a mouse, or data taken from a telecommunication line such as the Internet or an external storage device can be used. (Step S1 in FIG. 2).

The input data fetched by the data input means 1 is stored in the data storage means 2 as a data file (step S2 in FIG. 2). This work is usually performed by providing a specific management area or directory on a file system provided by an operating system (basic software; OS) and creating a file in which the contents of the input data are recorded. it can.

A specific code indicating the type of data, such as document data or component data, or a keyword or tag description is defined and attached to the data file, and can be used in the subsequent inspection of the component data. To do.
For example, in the XML document, the component x is described in a format surrounded by a start tag and an end tag (“<x>”, “</ x>”), or in a format of <x “attribute” />. At this time, for example, the document data is described in a text range enclosed by <contents> tags, and the component data is described in <actor>.
> And <shape> tags. In the data presentation system according to the present embodiment, individual unique ID information is always described in the component data, and is used for component identification and database management.

The data file stored in the data storage means 2 may include not only document data and component data but also arbitrary data. Further, a single type of data is not always recorded in each file, and a plurality of data may be recorded in one file.

Therefore, in order to select document data and component data as reference sources from the data file stored in the data storage unit 2 and to manage them individually, the component extraction unit 6
Reads out the data file stored in the data storage means 2 (step S3 in FIG. 2), checks whether component data is described, and if so, outputs the content together with ID information as component data and outputs the component data. It is registered in the storage means 7 (step S4 in FIG. 2). The processes in steps S3 and S4 are performed on all data files stored in the data storage unit 2 (step D1 in FIG. 2).

The ID information of a part is unique (uniquely determined) in the use range of the present system.
What is determined as identification information is sufficient. For example, a 128-bit length sequence UUID (Universal Unique ID, Global Unique I
D, GUID) and a URL (Uniform Resource) for specifying a unique file name on the Internet.
Locator) and Java for specifying a Java package module that is unique on the Internet
Various IDs such as a Package Name character string
Information can be used.

Hereinafter, as examples corresponding to the present embodiment, examples of document data and component data will be described. FIG. 3A shows the XML data file “alien.xm”.
1 ". Referring to FIG. 3A, the component content (content) serving as the root of the hierarchical structure includes a component scene (scene), and the component scene is a component actor (acto).
r). The component scene and the component actor each describe unique ID information by UUID. The component data and the ID information are described so as to correspond one-to-one.

In the example of FIG. 3A, the component actor corresponds to a three-dimensional object to be displayed to the user, and can specify shape information, color, pattern, and animation. In this case, id = "11111111-
A854-11D3-A42C-00004CB315
5E ", the part data of the shape to be referenced, and the shape (sha
pe) is specified. However, since shape data, which is the entity of shape, is not described in this data file, in this case, it is necessary to separately refer to and import the corresponding component data.

FIG. 3B shows a data file “shape”.
1. xml "is an example of part data of a shape referred to by the document data of FIG. 3A. This part data describes a shape corresponding to the ID information specified in FIG. 3A as a part shape. Here, the entity of the shape is a polygon data file “Gray1_action1. x ".

The data of FIGS. 3A and 3B will be described as an example.
en. Read xml and inspect. At this time, if there is a root component content that declares a three-dimensional information document, the component search unit 3 outputs this component to the data updating unit 4 as document data.

The parts search means 3 simultaneously checks the reference to the external parts described in the document data (step S in FIG. 2).
5). At this time, ID information that refers to an external file or ID information that does not have entity data is searched for and output as ID information as a reference to an external component (step S6 in FIG. 2). This reference check is executed for all references described in the document data (step D2 in FIG. 2).

Based on the ID information retrieved by the component retrieval means 3, the component storage means 7
Happe (part name "alien shape") is searched, and the search result is used as the reference part data.
Output to The data updating unit 4 fetches the corresponding reference component data from the component storage unit 7 based on the ID information and embeds it in a location where the component data of the document data from the component search unit 3 is referred to, to generate a complete document. The generated document is output as updated document data (step S7 in FIG. 2).

The data presentation means 5 reads the updated document data and presents it as an image, video, audio, or moving image so that the user can view it (step S8 in FIG. 2). In this example, a three-dimensional object of shape information described by component data is arranged in a space, camera and light information are separately determined, and generally three-dimensional computer graphics (CG)
The rendering process (rendering) used in the technology is performed, and the rendering result is presented to the user.

When an interactive operation is set for the document data to be presented, the data presenting means 5 can present the data so that the user can perform an interactive operation. For example, with data described in the VRML language, interactive description such as a change in color or shape of an object can be made by a user's mouse click operation on a three-dimensional object. A similar interactive function is H
It can also be described in TML by describing a script. The data presentation means 5 can provide such an interactive function to the user.

In the above-described embodiment of the present invention, XML document data for describing a three-dimensional space has been described as an example.
In the case of a data presentation method that manages data by adding D information and further specifies a reference to a part in a document by ID information (eg, HTML, SGML, VRML, SMIL, etc.),
The invention can be implemented in exactly the same way.

Furthermore, differences, such as whether the data format is text-based or whether it is a commonly known and standardized format, do not preclude the practice of the present invention. The present invention can be implemented in exactly the same manner, even if the data description technique applies the same component management and reference relationship, for example, even in the case of binary data in a unique format designed specifically for an application.

In the first embodiment described above, the case where all the component data externally referenced by the document data are described in the data file without lack, and there is no lack or lack of the component data has been described as an example. However, when such a shortage of component data occurs, the data presentation system may indicate to the user the situation of component shortage, or take measures such as substituting predetermined default component data. Can be.

Next, the effect of the present embodiment will be described. In the present embodiment, documents and parts are extracted from the data file based on unique ID information and are managed and registered. Therefore, when a plurality of parts data or document data is described in the same data file, And
Alternatively, even when different types of data are described in the same data file, a complete compound document can be constructed without any problem, and this can be presented to the user. As a result, even if the number of data increases, a plurality of data can be described in the same file, and the data management cost can be significantly reduced.

(Second Embodiment) Next, a second embodiment of the present invention will be described.
An embodiment will be described in detail with reference to the drawings.
FIG. 4 shows a block diagram of a second embodiment of the data presentation system according to the present invention. In the figure, the same components as those of FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. In the second embodiment shown in FIG. 4, a data input unit 1, a data storage unit 2, a component search unit 3, a data update unit 4, a data presentation unit 5, a component extraction unit 6, a component storage unit Means 7
And a replacement designation storage means 8 and a component replacement means 9.

The exchange designation storage means 8 reads the data file stored in the data storage means 2 and checks whether or not the exchange designation data is described. If the exchange designation data is described, it is stored as exchange designation data. The part replacement means 9 corresponds to the ID information of the part data included in the document searched by the part search means 3 based on the reference relation between the parts described in the replacement specification data stored in the replacement specification storage means 8. Check if there is a reference relationship between parts. If there is a corresponding reference relationship, the ID information of the corresponding component is output to the component storage means 7.

The data updating means 4 generates a complete compound document incorporating external components based on the document data retrieved by the component retrieval means 3 and the reference component data and ID information stored in the component storage means, and updates the document. The updated document data is output to the data presenting means 5 as data, whereby the updated document data is presented to the user.

Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG. In the figure, the same reference numerals are given to the same processing steps as in FIG. 2, and the description thereof will be omitted. 4, the component extracting means 6 reads out the data file stored in the data storage means 2 (see FIG. 5).
In step S3), it is checked whether the component data is described. If the component data is described, the content is output together with the ID information as component data and registered in the component storage unit 7 (step S4 in FIG. 5).

The exchange designation storage means 8 reads the data file stored in the data storage means 2 and checks whether or not the exchange designation data has been described. The data is stored in the exchange designation storage means 8 as data (step S9 in FIG. 5).
The processes in steps S3, S4, and S9 are performed on all data files stored in the data storage unit 2 (step D1 in FIG. 5).

Subsequently, the component search means 3 simultaneously checks the reference to the external component described in the document data (step S5 in FIG. 5), and when the document data includes the reference to the external component data, this corresponds. The ID information is output to the component replacement means 9, and it is checked whether or not replacement designation data corresponding to the ID information is registered in the replacement designation storage means 8 (step D3 in FIG. 5). If registered, the component replacement means 9 outputs ID information of the replaced component data to the component storage means 7 (step S10 in FIG. 5).

The part storage means 7 outputs the reference part data corresponding to the ID information (step S6 in FIG. 5). As a result, the part data applied to the document data in the data updating means 4 is replaced by the replacement designated by the replacement designation data. This will be the component data later. The reference check in steps S5, D3, S10, and S6 is executed for all references described in the document data (step D2 in FIG. 5).

An example corresponding to the second embodiment will now be described with reference to examples of document data and component data. FIG. 6A shows an example of the exchange designation data. In this exchange designation data, “alien” in FIG.
Using the shape information (FIG. 3 (b)) of the component actor defined as a replacement source, the shape of another replacement destination
The specification to be exchanged is described in the e information (FIG. 6B).
At this time, the replacement source information is designated by <shape_from “replacement source component data ID information” />, and the replacement destination information is <
This is designated by shape_to “replacement part data ID information” >>.

The part replacement means 9 reads the replacement designation data and outputs the ID information 1 of the search request to the replacement part data.

Next, effects of the second embodiment will be described. In the second embodiment, by providing the replacement designation storage means 8 and the component replacement means 9, the designation of the externally referenced component data described in the document data can be changed by the replacement designation data. At this time, there is no need to change the original document data at all, and it suffices to add replacement part data and replacement designation data. As a result, there is no need to update the markup description that refers to the component data in the reference source document, and the data update and management costs can be significantly reduced.

(Third Embodiment) Next, a third embodiment of the present invention will be described.
An embodiment will be described in detail with reference to the drawings.
FIG. 7 shows a block diagram of a third embodiment of the data presentation system according to the present invention. 4, the same components as those of FIG. 4 are denoted by the same reference numerals, and the description thereof will be omitted. Third in FIG.
This embodiment is characterized in that an application designation selecting means 10 is newly provided as compared with the second embodiment shown in FIG.

The application designation selecting means 10 defines the same component data as the exchange source, and therefore checks whether there is a plurality of exchange designation data in the exchange designation storage means 8 which have duplicate or conflicting references. When such a plurality of exchange designation data exist, the application designation selecting means 10
The attribute value of each exchange designation data is examined, and one exchange designation data to be applied is selected. The selected replacement designation data is output to the component replacement means 9 as the latest replacement designation data.

The component replacement means 9 determines the reference relation between the parts corresponding to the ID information of the part data included in the document searched by the part search means 7 based on the reference relation between the parts described in the latest replacement designation data. Find out if there is.

Next, the operation of the third embodiment will be described in detail with reference to the flowchart of FIG. 8, the same reference numerals are given to the same processing steps as in FIG. 5, and the description thereof will be omitted. In FIG. 8, application designation selecting means 1
0 checks the exchange designation data stored in the exchange designation storage means 8, and examines whether there is a plurality of exchange designation data defining the same component data as an exchange source (step D4 in FIG. 8).

If there is a plurality of exchange designation data and there is a conflict, the application designation selecting means 10 examines the attribute value of each of the conflicting exchange designation data and determines the exchange designation data to be applied based on these attribute values. Is selected and determined (step S10 in FIG. 8).

Hereinafter, an example corresponding to the third embodiment will be described with reference to examples of document data and component data.
FIGS. 6A and 6C show the shape part data (ID
Information "22222222-A854-11D3-A42"
C-00004CB3155E) is an example of a shape part, and is exchange designation data shown in FIGS. 6B and 6D.
Since both are in conflict, in this state, either one of FIGS. 6A and 6C must be selected and used as the latest exchange designation data to be applied.

At this time, the application designation selecting means 10 outputs the attribute value information of both (in this example, <info> “arrangement of attribute values”).
The data creation date and time described in </ info> is checked and a comparison is made. For example, the data with the newer creation date and time (the exchange designation data in FIG. 6C) is used as the latest exchange designation data. You can choose.

In this embodiment, the attribute values described in the exchange designation data are used. However, for example, the date and time of data file creation (using file creation date and time information managed by the basic software or the OS), the importance of data For example, an arbitrary attribute value set by the data creator may be used. Also,
An appropriate method is determined in advance for the comparison determination rule or determination algorithm for the attribute value,
0 can be given. Further, these comparison criteria may be specified or set by the user as well as the data creator.

In this example, a case in which two pieces of exchange designation data compete with each other has been described. However, the present invention can be similarly applied to a case where three or more pieces of exchange designation data are in conflict.

Next, the effect of the third embodiment will be described. In the present embodiment, the application designation selecting means 10
Is provided, when the designation of the externally referenced component data described in the document data is changed by the exchange designation data, even if a plurality of exchange designation data conflict, the data is applied by the comparison judgment based on the attribute value information. You can select the data.

That is, in the present embodiment, in order to update and change the data, the exchange selection data and the component data already existing in the system are not changed or corrected at all, but simply the optimum selection target is selected. What is necessary is just to add new replacement designation data and new parts data to the system. As a result, the update and management costs of the registration data can be significantly reduced.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described.
An embodiment will be described in detail with reference to the drawings.
FIG. 9 is a block diagram showing a main part of a fourth embodiment of the data presentation system according to the present invention. In the fourth embodiment, as shown in FIG. 9, the exchange designation selecting means 10 of the third embodiment shown in FIG. The feature is that data is calculated and output as the latest exchange designation data.

As shown in FIG. 9, the application designation selecting means 10 of the present embodiment comprises an exchange designation selecting means 21, an invalid designation checking means 22, an invalid list creating means 23, and a valid designation calculating means 24. It is configured.

The invalid designation search means 22 checks whether or not invalidation designation for other exchange designation data is described in all exchange designation data. If the result of the inspection includes an invalidation designation, the invalidation list creation means 23
The invalid specification is output to. Invalid list creation means 23
Creates an invalidation list composed of the indexes of the exchange specification data as elements based on the mutual specification of the invalidation specification.

The validity designation calculating means 24 searches the invalidation list for exchange designation data which does not receive the invalidation designation, and outputs the old information of the exchange designation data corresponding to the index of the search result to the exchange designation selection means 21. Exchange designation selection means 21
Temporarily stores the exchange designation data input from the exchange designation storage unit 8 in the application designation selection unit 10, selects the exchange designation data corresponding to the ID information, and outputs it as the latest exchange designation data.

Hereinafter, as an example corresponding to the fourth embodiment, an example of document data and component data will be described. FIG. 10 is an explanatory diagram showing the relationship between document data, component data, and exchange designation data when a plurality of exchange designation data exist for a single component reference and conflict.

In FIG. 10, the component shape in the document data 31 refers to the component data # 1. Also,
Similarly, in the invalidation list 32, competing exchange designation data ref2, ref3, and re with the component shape as a reference source.
f4 and corresponding component data # 2, component data # 3, and component data # 4.

FIGS. 6 (c), 11 (a) and 11 (b) are examples of the description of the exchange designation data corresponding to ref2, ref3 and ref4, respectively.
For ef2 and ref4, invalidation designation for ref3 is described. Invalid specification is <ove
rride “ID information of exchange designation data to be invalidated” /
>.

The invalidation designation designates invalidation of the existing exchange designation data, and is designated by the ID information of the exchange designation data. In this case, it is of course necessary to add unique old information to each exchange designation data and manage it. In addition, when the exchange specification data designated as invalid specifies another exchange designation data as invalid, the invalid specification can be applied retroactively.

In FIG. 10, ref 2 ← between exchange designation data
A list with an invalid designation of ref3 ← ref4 is formed, and only ref4 among them is selected as a valid exchange designation because the invalidation designation has not been made from anywhere.

In the reference relationship described with reference to FIG. 10, for example, ref3 loses data due to some reason (such as data loss due to storage device failure or elapse of the valid period of ref3), and as a result, the exchange designation data In some cases, the list may have multiple sublists or may be incomplete. In such a case, an effective exchange specification is made by performing a mutual comparison of attribute values between the respective sublists. Can be determined.

Further, in the validity designation calculating means 24 of this embodiment shown in FIG. 9, another attribute value such as an expiration date can be added to the validity designation as shown in FIG. FIG. 12 is an example of a description in the case where the application deadline and the day of the week are specified when applying the invalidation specification of FIG. 11B. The attribute values used here are not limited to those relating to time or day of the week. For example, attribute values (age, gender, occupation, etc.) of the user to use, attribute values of the place or area where the terminal exists (postal code) , Prefectural codes, terminal coordinates, etc.) can be used.

In the example of FIG. 12, the invalid designation for ref4 to ref3 is valid from March 1, 2000 to March 31, 2000, and is valid only on Monday, Wednesday, and Friday during this period. Is specified. That is, if this designation is applied, ref4
Is valid, and in other cases, ref3 is valid.

Further, in the present embodiment, even if unused replacement designation data and component data which were previously added to the user presentation system and were present but are not referred to at present are deleted, the data presentation to the user can be performed. There is no problem. For this reason,
It is possible to automatically delete a data file that is not already used on the terminal side, and it is possible to easily realize effective use of the data storage capacity inside the terminal device.

Whether or not the file is used is determined based on, for example, the elapsed time from the file creation date and time. If the data is exchange designation data, whether or not invalidation has been received from another, or if the component data is For example, it is possible to determine whether or not it is taken in and embedded in the document data and is to be presented to the user.

Next, effects of the present embodiment will be described. In this embodiment, when a plurality of pieces of exchange specification data conflict with each other in the application specification selection unit 10, the invalid specification for the existing exchange specification can be performed, so that the existing document data can be simply added. The document data presented to the user can be updated without changing any of the component data and the replacement designation data.

As a result, the parts making up the document data can be updated with the replacement designation data and the parts, and as a result, a part of the content to be presented can be automatically updated from the outside. is there. Another effect is that the unused data file can be automatically deleted. Also, when updating document data, exchange designation of personal presentation attributes such as date and time of browsing, gender and age of the user, geographical conditions such as viewing location, differences in document presentation environment such as display characteristics of terminal devices or browsing conditions, etc. It can be used as a valid condition for data.

As a result, the work cost required for updating the data can be significantly reduced, and the content and structure of the document can be changed so as to be optimal for the user's browsing situation. .

Although the above embodiment of the present invention is directed to a compound document in which a reference document is embedded in a reference source document, it is needless to say that the present invention can be applied to a hypertext document. .

[0093]

As described above, according to the present invention,
Two or more types of document hierarchies, that is, a document serving as a part and a compound document referencing the same, are provided, and a final document is generated by this reference. Have.

(1) The management cost of document data can be reduced. The reason is that even if the number of component data handled in the document data increases, the component data to be referred to is specified by unique ID information (tag), so that a plurality of document data or the component data can be stored in the same data file. This is because the number of data files to be handled can be reduced. Further, even if the unused data file is inspected and deleted, it does not hinder the presentation of the document data to the user, so that the terminal can delete the unused data file as a result.

(2) The cost of updating document data can be reduced. The reason is that the reference from the document data to the component data can be updated by the exchange designation data, and as a result, it is not necessary to update the markup description referring to the component data in the reference source document. In addition, even if a conflict occurs in the reference to the component data due to the addition of the data file, the reference relationship to be applied can be determined in one. As a result, the reference of the document data can be updated even if the data file is freely added. It is.

(3) A document having optimal contents can be generated and presented to the user in accordance with the document presentation environment or the difference in the user's browsing conditions. This is because, when referring to the component data from the document data, the component reference can be selected and switched according to the presentation environment or the viewing condition.
