Data described in a language called “Language” is converted to HTTP (HyperText Transfer).
(Protocol).

In this type of network system, a Web server program is installed in a computer, that is, a Web server terminal connected to this network at various places, and a data file to be viewed is placed under the management of the Web server program. The user activates a browser (browsing program) mounted on his or her personal computer connected to the network, that is, a client terminal or the like, and obtains a URL (U.S.
niform ResourceLocator).

[0004] In response, the browser sends the specified W
The web server terminal is connected to the web server terminal via a communication line such as a LAN line or a telephone line by a communication protocol called TCP / IP, and data received from the web server terminal is displayed on a screen. After the data reception is completed, the connection with the Web server terminal is disconnected, and the connection is made again in response to a request for new data by the user, and the desired data is received and displayed.

FIG. 7 is an explanatory diagram showing a general information browsing system, particularly showing an example of a system operated in an office building. In this case, tenants A to C are occupied on the fifth and third floors, respectively, and a dining room is occupied on the second floor.
On the first floor, a building management room for maintaining and operating building facilities is provided.

A LAN line 10 is provided on each floor of the building, and a Web server terminal (server terminal) 11 provided in the building management room and client terminals 21 to 29 provided on each floor are connected to the LAN line 10. They are connected to each other via 10. In the Web server terminal 11,
Information to be notified to the resident of the building, for example, an HTML document indicating a floor cleaning notice, a cafeteria menu, and the like is stored and can be browsed from each of the client terminals 21 to 29 using a browser.

FIGS. 8A and 8B show screen output examples of the client terminal. FIG. 8A shows a menu for selecting and browsing various notices, and FIG. 8B shows a specific example of the notice. FIG.
In the notification menu of (a), “1. Notification from the building management room” and “2. Notification from the dining room” are prepared. Here, when "2. Notice from the dining room" is selected, "Today's set meal" as shown in FIG.

In order to achieve the above object, according to a first aspect of the present invention, in a data browsing system, a server terminal transmits a predetermined HT from a client terminal.
In response to a browsing request of an ML document, by referring to a browsing period in an expiration date setting file provided corresponding to the HTML document, it is determined whether or not the HTML document requested to be browsed can be displayed. And a display control processing means for distributing the HTML document only to the server. Therefore, only documents within the expiration date are distributed and viewed from the server terminal to the client terminal, and documents outside the expiration date are not distributed from the server terminal.

According to a second aspect of the present invention, in the information browsing system according to the first aspect, the display control processing means responds to each HTML document in response to a menu page request for browsing document designation from the client terminal. By referring to the browsing expiration date in the provided expiration date setting file, it is determined whether or not each HTML document can be displayed, and only the displayable HTML document is described on a menu page and distributed. Therefore, only documents within the expiration date are described on the menu page, and documents outside the expiration date are not described on the menu.

According to a third aspect of the present invention, in the information browsing system according to the first or second aspect, the server terminal includes:
Edit screen generation processing means for generating and distributing an HTML document indicating the edit screen in response to a request for setting the expiration date of the predetermined HTML document from the client terminal, and processing the contents edited by the client terminal using the edit screen. And a data update processing means for receiving the received data and generating an expiration date setting file corresponding to the HTML document. Therefore, when setting the expiration date at the client terminal, an editing screen is generated and distributed from the server terminal, and the contents input using this editing screen are stored in the expiration date setting file.

[0013]

Next, the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a processing operation at the time of browsing an HTML document by an information browsing system according to a first embodiment of the present invention.
(B) shows the term management data, and (c) shows the document display processing operation. In the following, HTML is used for any client terminal.
A case where a document is viewed will be described as an example. Note that the system configuration is the same as that of FIG. 7 described above.

In FIG. 1, an arbitrary H stored in the Web server terminal 11 is stored in the client terminal 21.
A browser 210 for browsing and displaying a TML document is provided. The Web server terminal 11 has an information storage unit 14 that stores various HTML documents and an expiration date setting file that stores expiration date data of these documents.
And a display control processing unit 15 that reads out from the information storage unit 14 and distributes it only when the requested document is within the expiration date in response to a browsing request from the client terminal 21.

When browsing an HTML document, FIG.
As shown in the figure, first, a browsing request from the browser of the client terminal 21, for example, the display control
Is transmitted. In response, W
The eb server terminal 11 activates the display control processing unit 15 and executes the processing as shown in FIG. FIG. 2 is a flowchart showing the display control processing operation.

First, the current date and time are obtained from a clock processing unit (not shown) provided in the Web server terminal 11 (step 151), and whether the browsing request from the client terminal 21 requests a specific document is determined. It is determined whether or not it is (step 152). If the specific document has not been requested (step 152: NO), it is determined that the request is for browsing the menu page, and the following menu distribution processing is executed (steps 161 to 168).

In the menu distribution process, it is first determined whether there is an unprocessed expiration date setting file (step 16).
1) If there is an unprocessed file (step 161:
YES), open the found unprocessed expiration date setting file, and read its contents (step 162). FIG.
(B) is an explanatory diagram showing an example of the contents of the expiration date setting file of each document. As the expiration date setting data, a “registration / deletion” column indicating the registration status of the corresponding document and a “display” indicating the viewing expiration date are displayed. "Start date and time" and "Display end date and time" are provided.

Here, if the state of the document in the expiration date setting file, for example, the document i is “registered” (step 163: YES), the display start date and time is set to “none” or the current date and time as a check of the viewing expiration date. It is determined whether or not it is earlier (step 164), and whether or not the display end date and time is “none” or later than the current date and time (step 165).

According to these determinations, if the current date and time is after the display start date and time and before the display end date and time, that is, if the current date and time is within the browse time limit (step 16).
4: YES, step 165: YES), read out the document i file corresponding to the unprocessed expiration date setting file from the information storage unit 14, and acquire the title (step 166).

Subsequently, the title of the document i and the URL indicating the storage location of the document in the information storage unit 14 are set as the hyperlink destination when the document i is selected on the menu page (step 167). Return. On the other hand, if the state of the document i is not “registered” in step 163 (step 163: NO), if the current date and time is not within the viewing time limit in steps 164 and 165 (step 164: NO or step 165: NO) , Without returning to the menu page.

In this way, by repeatedly executing steps 162 to 167 for all the expiration date setting files, a menu page including only documents within the expiration date is created. When the processing for all the expiration date setting files is completed (step 161: N
O), the created menu page is distributed to the client terminal 21 that has made the request (step 168), and a series of processing ends.

Therefore, the browser 210 of the client terminal 21 can automatically display a menu page composed of a viewable HTML document by displaying and outputting the distributed menu page on the screen. In the example of FIG. 1, among the documents A to F stored in the Web server terminal 11, as shown in FIG. 1B, the document that can be displayed as of “September 30, 1998” is the document A , E, and F, and only these three documents are displayed on the menu page displayed on the screen of the client terminal 21.

Here, when the user selects browsing of the document F, the browser 210 transmits the URL set on the menu page corresponding to the document F to the Web server terminal 11 so as to transmit the document F. Make a browsing request. In response, the display control processing unit 15 of the Web server terminal 11 is activated, and executes the processing shown in FIG.

First, after obtaining the current date and time (step 1
51) It is determined whether a specific document is specified by the browsing request (step 152). In this case, since the document F is specified, it is determined that the browsing request is for the document F instead of the menu page. (Step 152: YE
S), the following requested document distribution processing is executed (steps 171 to 176).

In the request document distribution process, first, the expiration date setting file of the request document is opened, its contents are read (step 171), and it is determined whether or not the state of the request document is "registered" (step 172). Here, if the state of the request document is “registered” (step 172: YES),
As a check of the viewing expiration date, it is determined whether or not the display start date and time is "none" or before the current date and time (step 173), and it is determined whether or not the display end date and time is "none" or after the current date and time. (Step 17
4).

According to these determinations, if the current date and time is after the display start date and time and before the display end date and time, that is, when it is within the browse time limit (step 17).
3: YES, step 174: YES), read the document file F corresponding to the unprocessed expiration date setting file from the information storage unit 14, and request the client terminal 2
1 (step 175), and the series of processing ends. As a result, the content of the document F, for example, “notice from the dining room” as shown in FIG. 8B is displayed on the screen of the client terminal 21 by the browser 210.

On the other hand, if the state of the document F is not "registered" in step 172 (step 172: N
O) In Steps 173 and 174, if the current date and time is not within the viewing time limit (Step 173: NO or Step 174: NO), the document F is not delivered, and the client terminal is notified that the requested document cannot be displayed ( Step 1
76), a series of processing ends.

As described above, in the present embodiment, the display control processing unit 15 is provided in the Web server terminal 11, and the document requested to be browsed is referred to by referring to the expiration date setting file created corresponding to each document. Is determined, and the request document is distributed to the client terminal 21 only when the display is permitted, so that the expiration date management of each HTML document can be executed accurately, and the HTML content whose notification content has expired has passed.
Documents are not browsed, and confusion to the user due to browsing outside the notice expiration date can be avoided.

Also, in response to a menu page request from the client terminal 21, the document is set to a menu page, and only the documents that can be displayed are distributed with reference to the expiration date setting file of each document. The user is not selected by mistake, and the above-mentioned confusion of the user can be prevented.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is an explanatory diagram showing a processing operation when setting an expiration date of a document by the information browsing system according to the second embodiment of the present invention, and is the same as or equivalent to that described above (see FIG. 1). Are denoted by the same reference numerals. In the following, a case where an expiration date of an HTML document is set when editing the HTML document will be described as an example.

In FIG. 3, the Web server terminal 11 generates and distributes an HTML document for an edit screen in response to a document edit request from the client terminal 21, and uses the edit screen. And a data update processing unit 13 for updating a document file and an expiration date setting file based on the edited contents input by the user. The information storage unit 14 stores a data file for storing the contents of each HTML document in addition to the document file and the expiration date setting file.

When editing an HTML document, the client terminal 2
In step 1, editing is performed by the browser 210 using an editing screen 100 as shown in FIG. FIG. 4 is an explanatory diagram showing an example of the editing screen. On the editing screen 100, a plurality of templates serving as format samples of the HTML document are displayed. As shown in FIG. 4B, a plurality of items are arranged in different layouts in each template, and the creator selects any appropriate template.

On the editing screen 100, input items for inputting the contents are provided for each item used in the template, and are associated with the items of each template. Therefore, by inputting the contents into the necessary input items, the contents are reflected on each item of the selected template, and an HTML document is created.

The edit screen 100 is provided with two input items "display start date and time" and "display end date and time" as input items for setting the expiration date of the document.
Also, a “register” button and a “delete” button are provided as input means for setting the registration state of the document. Therefore, when the document is edited, the expiration date and the registration status are set by using these, and the contents are stored in the corresponding expiration date setting file in the Web server terminal 11.

The processing operation when editing an HTML document will be described below with reference to FIGS. FIG. 5 is a flowchart showing the operation of the edit screen generation processing unit, and FIG. 6 is a flowchart showing the operation of the data update processing unit. In FIG. 3, first, a request for editing a predetermined document, for example, “Document A” is made from the browser 210 of the client terminal 21 (step 31).

In response, the editing screen generation processing unit 12 of the Web server terminal 11 starts the processing shown in FIG. First, it is determined whether or not a specific document is specified in the document editing request from the client terminal 21 (step 121). If the specific document is specified (step 121: YES), the requested document is determined. The data file of A and the expiration date setting file are read from the information storage unit 14 (step 122).

Then, based on the contents, an HTML document showing an editing screen of the document A is generated (step 12).
3) Delivery to the client terminal 21 via a communication line such as a LAN line or a telephone line, here, the LAN line 10 (step 32). In the first embodiment, it has been described that the menu page is created by the display control processing unit 15, but the menu page may be created by the edit screen generation processing unit 12.

In this case, as shown in FIG. 5, if a specific document is not specified in step 121 (step 121: NO), the data file of all documents and the expiration date setting file are stored in the information storage unit. 14 (step 124). Then, in the same manner as described above (see FIG. 1), a menu page is generated by selecting only documents that can be browsed based on the expiration date of each document (step 12).
5).

As described above, the Web server terminal 11
In the edit screen generation processing unit 12, the HT for the edit screen
An ML document is generated, and the client terminal 2 of the editing request source
1 is delivered. In response, the client terminal 21
The browser 210 opens an HTML document indicating the distributed editing screen 100 (step 211).

As a result, the editing screen 100 for the document A is displayed on the screen of the client terminal 21, the template used for the document A is selected by the creator, and the item of the document A is added to each item used in the template. The content is entered. Further, the expiration date of the document A is set in each of the input items of “display start date and time” and “display end date and time”, and the “registration” button is pressed according to the end of all the inputs.

In response, the template type selected from the browser 210 and the input contents of each item are transmitted to the Web server terminal 11 as input data (step 33). The data update processing unit 13 of the Web server terminal 11 starts the processing shown in FIG. 6 in response to receiving the input data from the client terminal 21.

First, the document data indicating the contents of the document A and its expiration date data are extracted from the received input data (step 131), and the information storage unit 1 corresponding to the document A is retrieved.
The expiration date data is written to the expiration date setting file in Step 4 (Step 132). At the same time, the document data is stored for each item in the data file in the information storage unit 14 corresponding to the document A (step 132).

Here, the contents of the items shown in FIG. 8B, for example, the title 81, the text 82, the image 83, and the text 84 are stored in the data file (step 133), and the next document editing is performed. Sometimes read and reused. Similarly, the expiration date setting file is read out and reused at the next document editing.

Subsequently, the data update processing unit 13 generates and updates an HTML file corresponding to the document A in the information storage unit 14 based on the previous document data (step 13).
4). Then, an HTML document for displaying the editing result of the document A, for example, the success / failure of the expiration date setting file and the HTML file generation / update is generated (step 1).
35), and deliver it to the client terminal 21 (step 3)
4).

In response to this, the browser 210 of the client terminal 21 sends the distributed editing result display HTML.
Open the document (step 212). Thus, the editing result of the document A is displayed on the screen of the client terminal 21.

As described above, in the present embodiment, when setting the expiration date of a document, the HTML document indicating the editing screen of the document requested to be edited by the client terminal 21 is displayed on the Web page.
Distributed from the server terminal 11, the client terminal 21
According to the expiration date data entered in the browser 210 of
The expiration date setting file stored in the Web server terminal 11 is updated.

Therefore, it is not necessary to previously provide a processing unit (program) for setting an expiration date and information necessary for editing and input, for example, screen information, for each client terminal. Can manage,
The information storage capacity of the entire network system can be used effectively. Further, even if a user who is not familiar with the computer programming language can use a browser installed in each client terminal, the expiration date can be set relatively easily from the client terminal.

In addition, an input item for setting an expiration date is provided on the editing screen used when editing an HTML document, so that the expiration date can be set at the time of editing a document. In the above description, the case of editing the notice from the dining room has been described as an example. However, the present invention is not limited to this. For example, the present invention is also applied when editing an HTML document indicating the notice from the building management room. Thus, the same operation and effect as described above can be obtained.

[0049]

As described above, according to the present invention, in response to a request for browsing a predetermined HTML document from a client terminal, the server terminal browses the expiration date setting file provided corresponding to the HTML document. By referring to the expiration date, it is determined whether or not the HTML document requested to be browsed can be displayed, and the HTML document is distributed only when the display is permitted. Therefore, only the documents within the expiration date are browsed from the server terminal to the client terminal. Documents that have been distributed and browsed and whose expiration dates have not expired are no longer distributed, and confusion to users due to browsing of HTML documents whose expiration date has passed can be avoided in advance and reliably.
