That is, the above-described files and folders constituting one electronic book data are stored in one virtual server to which one subdomain is assigned.
Here, the control unit 31 functions as an assigning unit that assigns different subdomains to each of a plurality of electronic book data.

  For example, the electronic book data shown in FIG. 11 is the virtual server to which the location (address) in the network indicated by the character string of the URL (Uniform Resource Locator) of “http://book01a.dpad.jp/” is assigned. Stored as data. Here, the subdomain individually assigned to each of the plurality of electronic book data is “book01a” which is a subdomain of “dpad”. In other words, in the present embodiment, each time e-book data is created, each e-book data is stored in a virtual server to which sub-domains having different sub-domains “dpad” shown in FIG. 11 are assigned.

  Generation of subdomains and virtual servers may be static or dynamic. For example, the control unit 31 operates a plurality of virtual servers to which a plurality of different subdomains are assigned in advance, and saves one of the existing virtual servers each time the creator instructs to save the electronic book data. You may make it allocate to the electronic book data to be performed. In addition, the control unit 31 performs a process of operating a new virtual server each time the creator instructs to save electronic book data, and the subdomain is different from the subdomain assigned to the already operating virtual server. May be assigned to a newly activated virtual server and assigned to electronic book data stored in the virtual server.

  In addition, the subdomain generation rule assigned to each of the plurality of electronic book data is not particularly limited, but is preferably determined in advance. As a subdomain generation rule, for example, a subdomain is a serial number corresponding to a character string indicating a serial number according to the order in which the electronic book data is stored or a part of a predetermined character string (for example, the beginning or end of the character string) And a rule such as a character string to which is added. The rule is an example, and the present invention is not limited to this. For example, a random character string may be used as a subdomain character string.

  In the present embodiment, electronic book data stored in a virtual server is disclosed as static data. That is, the electronic book data does not include dynamic data that changes depending on information transmitted from an external device (for example, the electronic book viewer 4), and responds to a data acquisition request made from the external device. And stored in the storage unit 32 as data to be distributed.

  The preview button 106 g is an input button for confirming the display content of the page edited on the page editing screen 106 with the electronic book viewer 4. Details thereof will be described later.

When the page delete button 106h is operated by the creator, the server 3 performs processing for deleting the page displayed when the page delete button 106h is operated from the contents of the electronic book.

Next, processing related to browsing of electronic book data will be described.
For example, as shown in FIG. 12, an electronic book viewer (hereinafter simply referred to as “browser”) assigns to one electronic book data via a web browser executed by the electronic book viewer 4. When a URL corresponding to the subdomain (for example, “http://book01a.dpad.jp/” shown in FIG. 11) is input, the electronic book viewer 4 requests a data acquisition corresponding to the input URL. To the server 3.
The server 3 displays data for displaying a download screen 201 having an input button (download button 201a) for downloading the electronic book data of the URL corresponding to the data acquisition request from the electronic book viewer 4 as an electronic book viewer. 4 to send.
When the user operates the download button 201 a on the download screen 201, the electronic book viewer 4 transmits a request for downloading electronic book data to the server 3. When receiving the download request for the electronic book data, the server 3 reads it from the storage unit 32 and transmits (distributes) it to the electronic book viewer 4. The electronic book viewer 4 receives electronic book data as shown in FIG.

When receiving the electronic book data, the electronic book viewer 4 sorts and stores the electronic book data in the local web cache and the local DB of the web browser.
Specifically, the control unit 41 stores data used in common for a plurality of electronic book data in the local web cache. Examples of data commonly used for a plurality of electronic book data include an icon image of an electronic book included in an “img” folder of electronic book data, a background image determined by a template, and the like. Further, the control unit 41 stores different data for each electronic book data in the local DB. Examples of data different for each electronic book data include various scripts such as “bookinfo.js” and “page.js”, icon images included in the “img” folder, images other than the background image, and the like. The control unit 41 stores different data for each electronic book data as one binary data for each electronic book data unit in the local DB.

Here, the electronic book viewer 4 uses the sub-domain from which the electronic book data is acquired as the data capacity of a non-volatile storage device (for example, the storage unit 42) for storing the electronic book data acquired via the web browser. A predetermined amount of data is allocated to each including domain. That is, the control unit 41 of the electronic book viewer 4 individually provides a local web cache and a local DB for each of a plurality of electronic book data acquired from different subdomains.
In this embodiment, the data capacity of one local web cache is 5 megabytes (MB), and the data capacity of one local DB is 50 MB. That is, the electronic book viewer 4 allocates and stores a maximum data capacity of 55 MB for one electronic book data.

  Note that both the local web cache and the local DB are storage area sections managed by the control unit 41, and various data stored in the local web cache and the local DB are both stored in the storage unit 42.

  Further, for example, as illustrated in FIG. 14, the control unit 41 creates an icon 202 a corresponding to the received electronic book data on the initial display screen 202 of the electronic book viewer 4. The icon 202a is generated individually for each of a plurality of electronic book data.

  When an operation (for example, a click operation) is performed on the icon 202a by the viewer, the control unit 41 executes a web browser and reads and displays electronic book data as data to be displayed by the web browser, as shown in FIG. Let That is, the control unit 41 reads and displays data corresponding to one electronic book data corresponding to the operated icon 202a among the data stored in the local web cache and the local DB. At this time, since the electronic book viewer 4 displays the electronic book using the data already stored in the storage unit 42, it is not necessary to acquire electronic book data from the server 3 again.

  In the example illustrated in FIG. 15, the electronic book viewer 4 displays two spread pages included in the electronic book data, but is an example, and the present invention is not limited to this. For example, the electronic book viewer 4 may display one page at a time, or may display three or more pages in a predetermined format (for example, a thumbnail format).

Next, the flow of processing related to creation and browsing of electronic book data will be described with reference to the time charts of FIGS. 16, 17, and 18.
16 and 17 are time charts showing an example of a flow of processing (creation processing) related to creation of electronic book data.
First, when an input operation indicating the start of login processing is performed by the creator via the terminal 2 (step S1), the server 3 transmits data for displaying the login screen 101 on the terminal 2 (step S2). ). The terminal 2 performs screen display according to the data transmitted from the server 3, but omits description of screen display processing in the following description and time chart.

  When an ID and a password are input by the creator on the login screen 101 (step S3), the server 3 uses the input ID and password and a combination of the ID and password stored in the storage unit 32 in advance. Collate. Here, when it is determined that there is an ID and password combination that matches the input ID and password (step S4: YES), the server 3 permits the creator to log in, and causes the terminal 2 to manage the production management screen 102. Data transmission for displaying is performed (step S5). On the other hand, when it is determined that there is no combination of ID and password that matches the input ID and password (step S4: NO), the server 3 displays a predetermined error screen on the terminal 2 and ends the process.

In the production management screen 102, when the new creation button 102a is operated as an instruction input for creating new electronic book data by the creator (step S6), the server 3 displays data for displaying the title input screen 103 on the terminal 2 Transmission is performed (step S7).
When a title and subtitle are input by the creator on the title input screen 103 (step S8), the server 3 temporarily stores the input title and subtitle character strings in the RAM 31b or the like (step S9), and the terminal 2 is transmitted to display the template selection screen 104 (step S10).

When a template is selected by the creator on the template selection screen 104 (step S11), the server 3 transmits data for causing the terminal 2 to display a page list screen 105 including an arrangement pattern corresponding to the selected template. It performs (step S12).
When the creator clicks on any page as an input instruction for page editing on the page list screen 105 (step S13), the server 3 displays the page editing screen 106 for editing the specified page on the terminal 2. Data transmission for display on the screen is performed (step S14).

  In the page editing screen 106, a character string is input or an image is arranged by the creator (step S15). When the save button 106f is operated as an input for instructing saving of electronic book data (step S16), the server 3 Generates electronic book data corresponding to the input contents of the creator on each screen relating to the creation of the electronic book (step S17), and stores the generated electronic book data in a virtual server to which individual subdomains are assigned. (Step S18).

FIG. 18 is a time chart illustrating an example of a flow of processing (browsing processing) related to browsing electronic book data.
When the URL of the electronic book data is input by the viewer via the web browser of the electronic book viewer 4 (step S21), the server 3 transmits data for displaying the download screen 201 on the electronic book viewer 4. (Step S22). The electronic book viewer 4 performs screen display according to the data transmitted from the server 3, but omits description of screen display processing in the following description and time chart.
When the download button 201a is operated by the viewer on the download screen 201 (step S23), the server 3 reads the electronic book data corresponding to the URL input in step S21 and transmits (distributes) it to the electronic book viewer 4. (Step S24).
When receiving the electronic book data, the electronic book viewer 4 sorts and stores the electronic book data in the local web cache and the local DB (step S25). Further, the electronic book viewer 4 creates an icon 202a corresponding to the received electronic book data on the initial display screen 202 (step S26).
When an operation is performed on the icon 202a by the viewer, the electronic book viewer 4 executes a web browser and reads and displays electronic book data as data to be displayed by the web browser (step S27).

Electronic book data may be created using the electronic book viewer 4. In this case, the electronic book viewer 4 previews the electronic book data being created on the page list screen 105 and the page editing screen 106 in addition to the various processes related to the creation of electronic book data by the terminal 2 described above. Can do.
For example, when the preview button 105b is operated by the creator on the page list screen 105, the control unit 41 executes the web browser, and the page based on the arrangement pattern selected in the page list area 105a is displayed as data to be displayed by the web browser. Display the display contents of. In addition, when the creator operates the preview button 106g on the page editing screen 106, the control unit 41 executes the web browser and displays the display content of the edited page as data to be displayed by the web browser.

  As described above, according to the information processing system 1 of the present embodiment, the control unit 31 of the server 3 allocates a different subdomain to each of a plurality of electronic book data, and therefore a storage unit that is allocated to store the acquired electronic book data. In the electronic book viewer 4 that manages the upper limit of the data capacity of 42 in units of subdomains from which electronic book data is acquired, the data capacity of the storage unit 42 managed in units of domains including the subdomains is set as one electronic book data. Can be assigned. That is, the data capacity of the storage device managed in units of domains including subdomains can be utilized to the maximum for storing one electronic book data, and one electronic book is stored in the storage unit 42 of the electronic book viewer 4. Since the data capacity for storing all the data constituting the data can be more easily secured, all the data constituting the electronic book data browsed or downloaded in the past is stored in the storage unit 42 of the electronic book viewer 4. When the contents of electronic book data browsed or downloaded in the past are browsed again, there is no need to acquire the electronic book data again. Thus, when browsing the contents of electronic book data browsed or downloaded in the past, the viewer can immediately start browsing without waiting for the waiting time until the completion of acquisition of the electronic book data. In addition, even if the network connection is not possible for some reason, it is not necessary to re-acquire the e-book data via the network, so the user can re-read the contents of the e-book data that has been browsed or downloaded in the past without any problem. can do. Thus, the electronic book data can be used more comfortably by the information processing system 1.

  Moreover, since the control unit 31 of the server 3 individually assigns virtual servers having different subdomains to each of the plurality of electronic book data, it is not necessary to assign individual physical servers to each of the plurality of subdomains. Since one server 3 can manage a plurality of subdomains, one server 3 can assign different subdomains to each of a plurality of electronic book data.

  Further, since the electronic book data is static data, the load on the server 3 when the electronic book data is sent from the server 3 to the electronic book viewer 4 can be reduced, and a plurality of communications are simultaneously generated. Even in this case, browsing or downloading can be performed more comfortably.

  Further, the control unit 31 of the server 3 uses the electronic book based on the template selected from among a plurality of templates for determining the arrangement of the character strings included in the page of the electronic book data and the correspondence between the character strings and the background. Since the data is generated, the creator can determine the arrangement of the character string included in the page of the electronic book data and the correspondence between the character string and the background by selecting the template, making the electronic book data easier. Can be created.

  The embodiment of the present invention should be considered that the embodiment disclosed this time is illustrative and not restrictive in all respects. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

For example, the electronic book viewer 4 is not limited to iPad. Further, the electronic book viewer 4 is not limited to the electronic book viewer 4 using the local web cache and the local DB. The present invention can be applied to an information processing system using an electronic book viewer that limits data capacity in units of subdomains.
In addition, standards (for example, FLASH (registered trademark), JavaScript (registered trademark), JSONP format, etc.) adopted for programs and scripts are merely examples, and are not limited thereto, and can be interpreted by a web browser, for example. It can be replaced with programs and scripts in other languages.

Further, link information for referring to external data can be included in the electronic book data. For example, instead of an image arranged on a page of an electronic book, reference information such as a URL for referring to external image data may be included as data in the page. Note that an image includes both a still image and a moving image.
Further, link information for referring to an external web page or the like may be included in the character string of the page.
