Content management system, content management method, and content management apparatus

The present invention relates to a content management system, a content management method, and a content management apparatus for managing digital content that can be accessed via a network.

Conventionally, a method for publishing content by storing content including text information and image information in a server is known. A user of a terminal connected to the server via a network such as the Internet can download the content by operating an icon displayed on the terminal, and can edit the downloaded content (for example, Patent Documents). 1).

JP 2001-195394 A

By the way, in recent years, an environment for posting content on a homepage or sharing it with many people using SNS (Social Networking Service) has been prepared, and content created by general users is distributed over the network. Opportunities are increasing. It is easy to edit the content downloaded from the server and publish the edited content.

Some people who have created content do not want the content they created to be published in an edited state. On the other hand, there are people who want to make effective use of many people by publishing the content created using their own content. However, conventionally, the handling of the downloaded content has to be left to the judgment of the person who downloaded the content, and there has been a problem that it may not be used as desired by the person who created the content.

Therefore, the present invention has been made in view of these points, and an object of the present invention is to provide a content management method capable of controlling how to use content distributed via a network.

The content management system according to the first aspect of the present invention is a content management system that includes a client terminal and a server and manages content browsed by the client terminal. The server associates the content, an icon that is an image associated with the content, and a usable condition of the content in a content storage unit, and stores the content from the client terminal. A server communication unit that transmits the content stored in the content storage unit to the client terminal in response to receiving the requested content request. The client terminal includes an operation unit that receives the icon selection operation, and a terminal communication unit that transmits the content request for requesting the content corresponding to the icon to the server when the operation unit receives the selection operation. Have.

The content management unit associates the parent content that can be used in the first usable condition, the parent icon that is an image associated with the parent content, and the first usable condition in the content storage unit in association with each other, The terminal communication unit transmits a creation request for requesting creation of child content created by adding unique content to the parent content to the server, and the content management unit sends the creation request to the server communication unit. When received, when the first usable condition permits the citation of the parent content, the child content in which the original content is added to the parent content and a child that is an image associated with the child content The icon and the second usable condition of the child content are associated with each other and stored in the content storage unit.

According to such a content management system, child content created by adding original content, such as know-how on how to use the product, created by the user who purchased the product to the parent content such as the instruction manual of the product. As well as the conditions under which child content can be used. Therefore, it is possible to manage the parent content created for the purpose of being widely released and the child content whose release range is to be restricted under different usable conditions.

The content management unit stores the parent content and the unique content in different areas of the content storage unit, respectively, and stores the child content including a link to the parent content and a link to the unique content in the content storage. You may memorize in a part. The content management unit may store the parent content in the content storage unit and store the child content including the link to the parent content and the unique content in the content storage unit.

Further, when the operation unit receives the child icon selection operation, the terminal communication unit transmits a child content request for requesting the child content to the server, and the server communication unit transmits the child content request to the server. When received from the client terminal, a link to the parent content and a link to the unique content may be transmitted to the client terminal.

In this way, when child content is created, it is not necessary to secure a storage area for storing the parent content included in the child content, so that the amount of the storage medium can be suppressed. Further, when the parent content is changed, there is no need to change the child content including the parent content.

Further, the server communication unit receives a second availability condition that is an availability condition for the child content from the client terminal, and the content management unit associates the second availability condition with the child content. You may memorize | store in the said content memory | storage part.
In this way, for example, it is possible to widely quote parent contents that are widely disclosed, such as product instruction manuals, etc., and opportunities to cite child contents that you do not want to be widely disclosed, such as original know-how Can be limited.

The client terminal further includes an acquisition unit that acquires text information related to the parent content, and the terminal communication unit transmits the creation request including the text information acquired by the acquisition unit to the server. May be.
In this way, for example, the user of the client terminal can photograph the JAN code of the product and create child content in which the unique content is added to the content related to the product corresponding to the text information included in the JAN code.

The content management unit may delete the parent content from the child content when the first usable condition is changed to a condition that does not allow the parent content to be cited. In addition, the content management unit may prohibit access from the child content to the parent content when the first usable condition is changed to a condition that does not permit citation of the parent content.
By doing so, it is possible to prevent browsing of the parent content even if the child content is accessed when the disclosure of the parent content is stopped.

Further, the content management unit stores creator information indicating the creator of the content in the content storage unit in association with the content, and based on the creator information received from the client terminal by the server communication unit The content may be changed.
In this way, it is possible to prevent the contents other than the creator of the contents from changing the contents of the contents and the usable conditions of the contents even for the published contents.

In addition, the content management unit stores the client terminal that has distributed the icon corresponding to the content in association with the content as a distribution destination terminal in the content storage unit, and the server communication unit deletes the content Then, an instruction to delete the icon may be transmitted to the distribution destination terminal of the icon.
By doing in this way, when the content is deleted, it is possible to prevent the user of the client terminal having an icon for browsing the content from trying to access the deleted content.

The content management unit stores the client terminal that is permitted to transmit the child content in the content storage unit in association with the child content, and the content request received by the server communication unit is The child content may be transmitted to the client terminal when the content is transmitted from the client terminal permitted to transmit the content.
In this way, even if the icon corresponding to the child content is illegally distributed, the viewing range is limited so that only the person permitted by the creator of the child content can view the child content. be able to.

The content management unit stores a plurality of the child contents including the parent content in the content storage unit, and the server communication unit issues a search request for searching for the child content including the parent content. May receive a plurality of child icons corresponding to the plurality of child contents including the parent content to the client terminal.
In this way, for example, when there are many child contents including know-how related to products related to the parent content, it becomes possible to extract and browse the child contents related to the product.

In addition, the content management unit stores, in the content storage unit, points to be given to the owner of the client terminal in association with the creator of the client terminal and the parent content, and the server communication unit stores the parent content When the creation request for the child content including: is received from the client terminal, points associated with the client terminal and the creator of the parent content may be increased.
By doing so, for example, it is possible to motivate the creation of child content including know-how related to the product related to the parent content, so that useful information about the product spreads and leads to product advertisement.

A content management method according to a second aspect of the present invention is a content management method for managing content browsed on a client terminal in a server, wherein the server can use parent content that can be used under a first usable condition, A step of associating a parent icon, which is an image associated with the parent content, with the first usable condition in a content storage unit, and storing the original content in the parent content corresponding to the parent icon; Sending a creation request for requesting creation of child content created by adding to the server, and when the server receives the creation request, the first availability condition permits citation of the parent content The child content in which the original content is added to the parent content. Comprising a Ntsu, a step of associating the child icon is stored in the content storage unit is an image associated with the child content and.

A content management apparatus (for example, a content server) according to a third aspect of the present invention is a content management apparatus that manages content browsed on a client terminal, and is the content and an image associated with the content. A content management unit that associates an icon with the content availability condition and stores the content in the content storage unit, and is stored in the content storage unit in response to receiving a content request for requesting the content from the client terminal. A server communication unit that transmits the content to the client terminal, wherein the content management unit includes a parent content that can be used under a first usable condition, and a parent icon that is an image associated with the parent content. , The first usable condition is associated with the container When the server communication unit receives a creation request for requesting creation of a child content created by adding unique content to the parent content corresponding to the parent icon from the client terminal, When the first usable condition permits citation of the parent content, the child content in which the original content is added to the parent content, and a child icon that is an image associated with the child content; Are stored in the content storage unit.

The details of the configuration of the content server 1 and the client terminal 2 will be described below with reference to FIG.

The server storage unit 11 includes, for example, a ROM, a RAM, a hard disk, and the like. The server storage unit 11 stores a content management program for causing the content server 1 to function. The server storage unit 11 may read and store a program stored in a storage medium such as an external memory or an optical disk, or may store a program downloaded from an external device via the network N.

The content storage unit 12 is configured by, for example, a hard disk. The content storage unit 12 stores the content, the icon that is an image associated with the content, and the content usable condition in association with each other. The content, the icon, and the content usable condition are stored in the content storage unit 12 as a database constructed together with other information. Usable conditions include, for example, conditions related to the range of other users who can search for content and the client terminal 2 (hereinafter referred to as “publication range conditions”), and conditions regarding whether or not new content can be created by quoting the content (hereinafter referred to as “content disclosure condition”). Is referred to as a citation permission condition).

The content management unit 13 is configured by a CPU, for example. The content management unit 13 executes the program stored in the server storage unit 11 to associate the content, an icon that is an image associated with the content, and the content usable condition in the content storage unit 12. Remember.

The server communication unit 14 has a communication interface for transmitting and receiving data via the network N, and transmits the content stored in the content storage unit 12 to the client terminal 2 in response to a request from the client terminal 2. Further, the server communication unit 14 receives various messages and data transmitted from the client terminal 2.

Specifically, when the operation unit 24 receives a selection operation, the terminal communication unit 26 transmits a content request message requesting content corresponding to the icon to the content server 1. In addition, the terminal communication unit 26 receives icons and content from the content server 1.

[Content structure]
Next, details of content managed by the content management system S will be described.
FIG. 3 is a diagram illustrating an example of content managed by the content management unit 13. FIG. 4 is a diagram illustrating an example of a data structure of content stored in the content storage unit 12. As shown in FIG. 4, the content storage unit 12 stores a content name, a parent content name, an icon image file name, a creator name, a usable condition, and a sub-content name in association with each other.

“Content name” is information for identifying the content. The “parent content name” is information for identifying the content cited in the content. The “icon image” is the file name or link name of the icon image corresponding to the content. The “creator name” is information that identifies the person or organization that created the content. Note that the creator name is not limited to the person or organization that actually created the content, but includes information that identifies the person or organization that has the authority to edit / delete the content or set the usable conditions. A plurality of creator names may be assigned to one content.

“Usage condition” is information indicating the disclosure range and citation availability of each content, and includes “publication range condition” and “quotation availability condition”. There are three types of disclosure range conditions, for example, “no restriction”, “white list”, and “black list”. Any client terminal 2 can access the content for which the disclosure range condition is set to “no restriction”. Only the client terminal 2 registered in advance in the white list can access the content for which the disclosure range condition is set to “white list”. Access to the content whose release range condition is set to “black list” by the client terminal 2 registered in advance in the black list is prohibited. The usable condition can be set by the user who created the content using, for example, a CMS (content management system).

There are two types of citation permission conditions, for example, “cited” and “not quotable”. Content whose citation permission condition is set to “citable” can be duplicated by user operation on the client terminal 2, or unique content created by the user of the client terminal 2 can be added. The content for which the quotation availability condition is set to “unquoted” can be viewed on the client terminal 2 but cannot be duplicated or added with original content. If the parent content is set to “cannot be quoted”, the parent content cannot be browsed from the child content unless the content itself is copied to the child content.

“Sub-content name” is information indicating a link to a storage destination of text information and image information included in each content. In this specification, the content that constitutes each content is referred to as sub-content.

[How to browse and create content]
Hereinafter, details of the browsing method and the creation method of each content will be described with reference to FIGS. 3 and 4.
For the content xa, the disclosure range condition is set to “no restriction”, and the citation permission / inhibition condition is set to “citable”. The content xa is created for the purpose of being viewed by many people. For example, the manufacturer of the product is the creator. In the present embodiment, the content xa is a content created by the manufacturer of the microwave oven, and is an instruction manual X1 for the microwave oven (product a) and a standard recipe for cooking that can be made using the microwave oven. It consists of a certain standard recipe X2.

Content xa is created without quoting other content. The content management unit 13 stores the content that can be used in the first usable condition, the icon that is an image associated with the content, and the first usable condition in the content storage unit 12 in association with each other. As shown in FIG. 4, the content storage unit 12 stores icon image files xa. “ico” and the usable conditions “no restriction” and “cited” are stored.

Since the disclosure range condition of the content xa is set to “no restriction”, any user considering the purchase of the product a downloads the icon xa used for browsing the content xa to the client terminal 2 and downloads the content. You can browse xa. For example, when the user shoots an image of a JAN code or QR code (registered trademark) pasted or printed on a catalog or advertisement of the product a using the shooting function of the client terminal 2, the terminal control unit 21 A JAN code or QR code, which is text information included in an image photographed by the photographing unit 25, is acquired. The client terminal 2 transmits an icon request message for requesting an icon for browsing the content xa corresponding to the acquired text information to the content server 1.

The content management unit 13 specifies the content xa corresponding to the text information included in the icon request message, and transmits the icon xa corresponding to the specified content xa to the client terminal 2. When the client terminal 2 receives the icon xa and displays it on the display unit 23, the user of the client terminal 2 can view the content xa by performing an operation (for example, a tap operation) to select the icon xa.
FIG. 5 is a sequence diagram in the case where the user who purchased the product a acquires the icon of the content xa.

The user uses the photographing function of the client terminal 2 to photograph the image of the JAN code or QR code affixed or printed on the product a catalog, warranty card, product body, etc. A JAN code or QR code, which is text information included in the image photographed at 25, is acquired (S11). For example, when the user of the client terminal 2 selects to create a new content on the menu screen displayed on the display unit 23 after capturing an image such as a JAN code, the terminal control unit 21 analyzes the captured image. As a result, the JAN code “491123456780”, which is text information included in the image, is acquired. The client terminal 2 transmits an icon request message for requesting an icon for browsing the content xa corresponding to the acquired text information to the content server 1.

The content management unit 13 specifies the content xa corresponding to the text information included in the icon request message (S12), and generates the icon xa corresponding to the specified content xa via the server communication unit 14 to generate the client Transmit to terminal 2. When the client terminal 2 receives the icon xa and displays it on the display unit 23, the user of the client terminal 2 can browse the content xa by performing an operation (for example, a tap operation) to select the icon xa (S13). ).

When the operation unit 24 of the client terminal 2 receives a tap operation for selecting the icon xa, the server communication unit 14 transmits menu content including a link to the content xa to the client terminal 2. When the terminal communication unit 26 receives the menu content, the display unit 23 displays, for example, the menu M1 shown in FIG.

When the operation unit 24 receives a tap operation for selecting the sub content X1 while the menu M1 is displayed, the client terminal 2 changes from the link destination of the sub content X1 to the sub content X1 via the terminal communication unit 26. An instruction manual corresponding to the content is acquired and displayed on the display unit 23. When the operation unit 24 receives a tap operation for selecting the sub-content X2, the client terminal 2 transmits the content corresponding to the sub-content X2 from the link destination of the sub-content X2 via the terminal communication unit 26. A standard recipe provided by the manufacturer is acquired and displayed on the display unit 23. The standard recipe includes, for example, text information related to a cooking method using the product a and image information such as a photograph of a dish after cooking.

FIG. 6 is a diagram showing a communication sequence when a child content is created by quoting the parent content. When the operation unit 24 receives an operation of uploading new content such as a unique recipe (S14), the terminal communication unit 26 instructs to create a new content and icon by quoting the parent content together with the unique recipe. Is sent to the content server 1. Upon receiving the content creation request message, the content management unit 13 confirms the usage conditions for the parent content (S15). The content management unit 13 transmits an error notification to the client terminal 2 via the server communication unit 14 when the parent content usable condition (first usable condition) does not permit the quoting of the parent content. .

When the parent content usable condition permits citation of the parent content, the content management unit 13 adds the child content mxa in which an area for storing the original content is added to the parent content, and the image associated with the child content mxa The child icon mxa and the usable condition (second usable condition) of the child content mxa are associated with each other and stored in the content storage unit 12.

3 and 4, the usable condition of the content xa is “cited”. Therefore, the content management unit 13 creates child content mxa including X3 (original recipe) as sub-contents in addition to the sub-contents X1 and X2 included in the content xa as the parent content, and stores them in the content storage unit 12. Store (S16). In the initial state, the content management unit 13 sets the disclosure range condition among the usable conditions of the child content mxa to “unlimited”, which is the same as the parent content xa, and the citation permission condition is different from the parent content xa, “unquoted”. Set to.

Subsequently, the content management unit 13 generates an icon mxa corresponding to the created child content mxa via the server communication unit 14 and transmits it to the client terminal 2. The image of the icon mxa is, for example, an image obtained by modifying a part of the image of the parent icon xa.

When the client terminal 2 receives the image file of the icon mxa, the client terminal 2 displays the received image of the icon mxa on the display unit 23. When the operation unit 24 receives a tap operation for selecting the icon mxa, the client terminal 2 receives a menu M2 different from the menu M1 of the parent content xa and displays it on the display unit 23 (S17). When the client terminal 2 receives the icon mxa and displays it on the display unit 23, the user of the client terminal 2 can view the content mxa by performing an operation (for example, a tap operation) to select the icon mxa. The child content mxa includes sub-contents X1 and X2 included in the content xa that is the parent content and X3 that is the sub-content added by the user M.

As shown in FIG. 3, the client terminal 2 can switch whether the child content mxa is set to a publicly set content or a non-publicly set content according to a user operation. For example, the client terminal 2 may display a public setting button for performing an operation for setting whether to disclose the child content mxa associated with the icon mxa together with the menu M2. When the user performs an operation of tapping the publish setting button, a screen for inputting whether to publish the child content mxa and whether to permit quoting is displayed. When the operation unit 24 receives a selection operation by the user, the terminal communication unit 26 transmits a usable condition setting message to the content server 1 instructing whether to publish and whether to permit citation. When the server communication unit 14 receives the usable condition setting message, the content management unit 13 stores the usable condition indicated by the received usable condition setting message in the content storage unit 12 in association with the child content mxa.

Note that the content management unit 13 does not have to create child content by quoting all of the parent content. For example, the content management unit 13 may create a child content by quoting some sub-contents of the parent content specified by the client terminal 2 and adding unique content to some of the sub-contents of the parent content. . For example, as shown in FIG. 4, the user N creates child content nxa including sub-contents X1, X2, and X4 based on the parent content xa, and the user S uses the child content nxa as the parent content, and the sub-content X1. , X4 and X5 may be created.

Further, when creating the child content, the content management unit 13 stores the parent content and the unique sub-content in different areas of the content storage unit 12, respectively, and links the parent content and the link to the unique sub-content. The child content to be included is stored in the content storage unit 12. Specifically, the content management unit 13 secures an area for storing the parent content xa and an area for storing the unique sub-content X3 in the content storage unit 12.

The content management unit 13 may store the parent content in the content storage unit 12 and may store the child content including the link to the parent content and the unique sub-content in the content storage unit. That is, the child content may include the parent content and the unique sub-content itself, or may include link information to the parent content and the unique sub-content.

[Relationship between content types and icons]
FIG. 7 is a diagram showing a relationship between icons and menus displayed when the icons are selected. In the client terminal 2, a parent icon (for example, corresponding to the icon xa) that is an icon of the parent content (for example, corresponding to the content xa) is composed of an image A. When the parent icon 1 is selected, a menu including “instruction manual” and “standard recipe” is displayed.

The image of the child icon (for example, corresponding to the icon mxa) of the child content (for example, corresponding to the content mxa) is, for example, an image in which the image A and the image B different from the image A are combined. When a child icon is selected after the child content is created, the original sub-content “Taro's Cooking Diary” is displayed in addition to the items included in the menu corresponding to the parent icon.

The grandchild icon image of the grandchild content created by quoting the child content is, for example, an image created by combining the image B included in the child icon and the image C different from the image B. When the grandchild icon is selected on the client terminal 2, in addition to at least a part of the menu corresponding to the cited child content, a menu including the newly added unique sub-content “Jiro's Kitchen Record” is displayed. The

[Operation when the usable condition is changed]
8 to 10 are diagrams for explaining the operation of the content management system S when the content state changes, and show the relationship between the parent content, the child content, and the grandchild content.
In FIG. 8, the parent content is composed of a parent original recipe, the child content is composed of a parent original recipe cited from the parent content, and a newly added child additional recipe, and the grandchild content is composed of the child content. It is shown that it is composed of a quoted parent original recipe and child additional recipe, and a newly added grandchild additional recipe. Each of the parent original recipe, the child addition recipe, and the grandchild addition recipe is stored in a different area of the content storage unit 12.

FIG. 9 shows a state in which the parent content is deleted. When an operation for deleting the parent content is performed at the client terminal 2, the client terminal 2 transmits a deletion request message for requesting deletion of the parent content to the content server 1. The deletion request message includes a terminal ID that identifies the client terminal 2 or a user ID that identifies the user of the client terminal 2. When the content server 1 receives the deletion request message, the content management unit 13 deletes the content requested to be deleted from the content storage unit 12, and the server communication unit 14 deletes the deletion completion message indicating that the deletion is complete. Is transmitted to the client terminal 2. When the client terminal 2 receives the deletion completion message, the client terminal 2 stops displaying the icon on the display unit 23.

Here, the content management unit 13 stores the creator information indicating the creator of the content in the content storage unit 12 in association with the content, and the content is based on the creator information received from the client terminal 2 by the server communication unit 14. It is determined whether or not deletion of the file is permitted. For example, the content management unit 13 refers to the creator information stored in the content storage unit 12 in association with the parent content, and the user ID that is the creator information included in the deletion request message received from the client terminal 2 It is confirmed whether or not the user corresponding to is the creator of the parent content.

The content management unit 13 deletes the parent content when the user ID included in the deletion request message matches the creator of the parent content. When the user ID included in the deletion request message does not match the creator of the parent content, the content management unit 13 does not delete the parent content, and does not delete the parent content via the server communication unit 14. A message indicating that the parent content cannot be deleted is transmitted.

When the parent content is deleted, the content management unit 13 deletes the link information to the parent content included in the child content and the grandchild content quoting the parent content. When the link information to the parent content is deleted, the item for selecting the parent content is not displayed on the menu displayed when the child icon or the grandchild icon is selected on the client terminal 2.

Further, when the parent content is deleted, the content management unit 13 may be configured to retain the link information to the parent content included in the child content and the grandchild content quoting the parent content as they are. Alternatively, instead of deleting the parent content, the content management unit 13 deletes only the link to the parent content included in the child content and the grandchild content quoting the parent content, or to the parent content and the parent content. It may be configured to restrict access to the parent content while maintaining the link.

In addition, when creating a child content quoting the parent content, if the configuration is such that a copy of the parent content is created instead of a link to the parent content and is recorded as a part of the child content, the content management unit 13 deletes the parent content. The quoted portion included in the child content and grandchild content may be deleted in synchronization with At this time, the content management unit 13 is configured to perform a synchronization process for matching the content of the parent content and the content of the child content quoting the parent content at an arbitrary timing separately from the deletion of the parent content. Also good.

Note that the content management unit 13 stores not only the content deletion but also the content information change and the content usage condition change in the creator information received from the client terminal 2 and the content storage unit 12. It is determined whether or not to permit based on the creator information.

FIG. 10 shows a state where the parent content cannot be quoted. When the client terminal 2 performs an operation of setting the parental content citation permission condition to “unquotable”, the client terminal 2 sets the parent content quoting permission condition to “unquotable” for the content server 1. Send an enabling condition setting message requesting that The usable condition setting message includes a terminal ID that identifies the client terminal 2 or a user ID that identifies the user of the client terminal 2. When the content server 1 receives the usable condition setting message from the client terminal 2 of the user who created the parent content, the content management unit 13 requests the parent content that is requested to set the citation permission condition to “not quotable”. The citation permission condition is changed to “not quotable”, and the server communication unit 14 transmits to the client terminal 2 a change completion message indicating that the change is completed.

The content management unit 13 deletes the parent content from the child content when the parent content citation permission condition is changed to a condition that does not permit the parent content citation. That is, the content management unit 13 deletes the link information of the parent content included in the child content, and changes the child content to a state including only the child additional recipe that is the unique sub-content or the link information of the child additional recipe. . Similarly, the content management unit 13 changes the grandchild content to a state including only the child addition recipe and grandchild addition recipe excluding the parent content, or link information thereof. When the parent content is deleted, even if a child content including a link to the deleted parent content is subsequently created, the parent content cannot be accessed from the child content.

When the parent content citation permission condition is changed to a condition that does not allow parent content citation, the content management unit 13 prohibits access from the child content to the parent content without deleting the parent content from the child content. May be. In this case, if the parental content citation permission condition is changed to a condition that permits quoting again, access from the child content becomes possible again. In addition, if the content of the parent content is changed when the citation permission condition of the parent content is changed to a condition that permits citation again, the content from the child content is synchronized with the change of the content of the parent content. The changed parent content can be accessed.

In addition, when creating child content that cites the parent content, if a copy of the parent content is created instead of a link to the parent content and recorded as part of the child content, the parental content citation availability condition is The content management unit 13 deletes the citation part of the parent content included in the child content and the grandchild content, or restricts access so that the user cannot view the citation part instead of the deletion. May be set. At this time, when the citation permission condition of the parent content is changed to a condition for permitting citation again, for example, the deleted citation part may be reconfigured or the access restriction may be released. Further, when the parental content citation availability condition is changed, the content management unit 13 matches the parent content and the content of the child content quoting the parent content at an arbitrary timing different from the change of the citation availability condition. For this reason, it may be configured to perform a synchronization process.

[Effect in the first embodiment]
As described above, according to the content management system S according to the present embodiment, when the parent content and the citation availability condition of the parent content are stored in association with each other and the citation availability condition permits citation of the parent content. Child content in which a unique sub-content is added to the parent content can be created. In this way, the person who created the content can control whether or not citation is possible while publishing the content. A person who has created child content by quoting the parent content can manage the parent content and the child content related to the parent content in a unified manner, so that the related information can be easily accessed.

<Second Embodiment>
[Control icon distribution permission terminal]
FIG. 11 is a communication sequence diagram in the content management system S according to the second embodiment.
The content creator can select a person who can access the child content mxa created by himself / herself, and only the selected person can access the child content mxa.

Specifically, when the user of the client terminal 2A shown in FIG. 11 inputs distribution destination information such as the user ID of the user of the client terminal 2B that permits browsing of the unique content mxa or the user's e-mail address, the client terminal 2A transmits to the content server 1 an icon distribution request message that includes the input distribution destination information and requests the client terminal 2B to distribute the icon.

When the server communication unit 14 receives the icon distribution request message, the client terminal 2B or the user ID of the client terminal 2B that is the distribution destination indicated by the distribution destination information in the received message is used to access the child content mxa. The client terminal 2B is registered as a distribution-permitted terminal by adding to the distribution-permitted terminal information indicating a terminal to be permitted and storing it in the content storage unit 12 (S21). That is, the content management unit 13 stores the client terminal 2B that is permitted to transmit child content in the content storage unit 12 in association with the child content.

Further, the content server 1 transmits the icon mxa to the client terminal 2B that is permitted to distribute. The client terminal 2B stores the received icon mxa in the terminal storage unit 22. Thereafter, when an operation of selecting the icon mxa is performed on the client terminal 2B, the client terminal 2B transmits a message requesting the content mxa including the user ID of the user of the client terminal 2B to the content server 1.

The content management unit 13 transmits the child content to the client terminal 2 when the content request message received by the server communication unit 14 is transmitted from the client terminal 2 permitted to transmit the child content. That is, when the content server 1 receives a message requesting the content mxa, the content management unit 13 refers to the distribution permitted terminal information stored in the content storage unit 12 in association with the content mxa, and sends the message to the client terminal 2B. It is determined whether or not the content mxa can be distributed (S23).

When the user ID included in the content request message requesting the content mxa is included in the distribution permitted terminal information, the content management unit 13 transmits the content mxa to the client terminal 2B. If the user ID included in the message requesting the content mxa is not included in the distribution permitted terminal information, the content management unit 13 transmits an error notification to the client terminal 2B.

In the above description, the processing in the case where the client terminal 2A transmits an icon to the client terminal 2B via the content server 1 has been described. However, the client terminal 2A attaches the icon to the electronic mail, You may transmit directly to the client terminal 2B. In this case, the client terminal 2A transmits to the content server 1 to the effect that the client terminal 2B is a distribution permission terminal.

[Effects of Second Embodiment]
As described above, the content server 1 according to the present embodiment transmits the child content to the client terminal 2 only when there is a content request from the client terminal 2 permitted by the child content creator. Therefore, it is possible to prevent a person who illegally obtained a child icon from browsing the child content even though the creator of the child content does not permit it.

Instead of displaying, the contents of the registered user information are displayed. When the user changes the registered user information, the client terminal 2 transmits the changed user information to the content server 1, and the content management unit 13 updates the user registration information to the changed user information.

Also, when the user performs an operation of selecting X7, an operation screen for adding an original recipe is displayed. Using the displayed operation screen, the user inputs unique information such as a unique cooking recipe or how to use a microwave oven and transmits it to the content server 1, or a file containing the unique information created in advance is stored in the content server 1. Or send. The content management unit 13 generates child content mxa9999 including unique information such as the received unique recipe, and transmits a child icon mxa9999 corresponding to the child content mxa9999 to the client terminal 2. When the user of the client terminal 2 selects the child icon mxa9999, a menu M5 is displayed on the display unit 23. The menu M5 includes X8 for browsing the unique recipe added by the user.

In addition, when the user selects X7, inputs unique information such as a unique cooking recipe, and transmits it to the content server 1, the user can add a recipe to X7 without generating new child content mxa9999. May be. At this time, when the content management unit 13 receives the unique information input by the user, the application added by the user of the icon xa9999 in addition to the basic recipe T1 created by the creator of X7 and stored in the content storage unit 12 The recipe T2 may be stored in the content storage unit 12, and T1 and T2 may be stored in the content storage unit 12 as contents associated with X7. By doing in this way, the user does not generate the child content mxa9999, but simply selects X7 displayed on the menu M4 of the xa9999, and the preset basic recipe T1 and the application recipe T2 added by the user are selected. It becomes possible to browse.

For example, the user sets the X6 public range to “white list” to prevent access by people other than those registered in advance, and sets the X8 public range to “unlimited”. Anyone can access their own information. By doing in this way, only original information, such as a cooking recipe which others want to see among the information which the user transmitted to the contents server 1, can be disclosed.

When the other user finds the child content mxa9999 by the search, the other user can create the grandchild content nxa9999 based on the child content mxa9999. The grandchild content nxa9999 includes a menu M6 including X1, X2, and X8.

[Effects of the seventh embodiment]
