It is a figure which shows the specific example of a direct access. It is a figure which shows the specific example of the display image (selected image). It is a figure which shows the comparative example of the direct access. It is a figure which shows the specific example of the processing executed by the display processing apparatus of FIG.

FIG. 1 is a diagram showing a specific example of a display processing device suitable for carrying out the present invention. In the specific example shown in FIG. 1, the display processing device 100 includes a data storage unit 10, a hierarchical structure management unit 20, an access authority management unit 30, an instruction reception unit 40, a node search unit 50, an image forming unit 60, and a display unit 70. The movement control unit 80 is provided.

The data storage unit 10 stores a plurality of data. A preferred specific example of the data storage unit 10 is a storage device such as a memory or a hard disk. The data storage unit 10 stores a plurality of files composed of various data such as document data and image data as typical examples.

The hierarchical structure management unit 20 manages a hierarchical structure relating to a plurality of data stored in the data storage unit 10. The hierarchical structure management unit 20 manages a plurality of files (data) stored in the data storage unit 10 in a tree-like hierarchical structure (see FIG. 2) having folders or files as nodes, for example.

The access authority management unit 30 manages access authority for a plurality of nodes (folders or files) having a hierarchical structure managed by the hierarchical structure management unit 20. For example, if the access right is set for a folder, the folder for which the access right is not set is not displayed on the display unit 70 (display or the like). Therefore, the user cannot expand the folder to which the access right is not set. However, this is just one example. For example, even if the folder has no access right, only the folder name may be displayed and the existence of the folder itself may be notified to the user. In this case, the user can know the existence of the inaccessible folder. However, the user cannot expand the folder or set the folder as the destination of the file. The access authority management unit 30 can also manage the user's access authority to a plurality of files (data) stored in the data storage unit 10. For example, the authority to manage access authority for each file (data), the authority to allow viewing of the contents of the file (excluding the file name), and the authority to allow editing (deletion, addition, change, etc.) of the file. May be managed.

For example, the access authority management unit 30 determines whether or not the user can access the node (folder or file corresponding to the node) for each node (each folder or each file) of a plurality of nodes managed in a hierarchical structure. Whether it is available or not) is managed. When there are a plurality of users, for example, the access authority of the user (whether or not each node can be accessed) is managed for each user. Of course, the access authority (whether or not the user belonging to the group can access each node) may be managed for each group composed of several users.

The instruction receiving unit 40 receives an instruction according to a user operation input via an operation device or the like. The instruction receiving unit 40 receives, for example, the designation of the target node among a plurality of nodes having a tree-like hierarchical structure.

The node search unit 50 searches for a node accessible to a user who has specified a target node in a plurality of nodes managed in a hierarchical structure. The node search unit 50 searches for accessible nodes adjacent to each other in the hierarchical structure, starting from the target node designated by the user, for example.

The image forming unit 60 forms a display image displayed on the display unit 70. The image forming unit 60 forms, for example, a display image including a tree display showing a plurality of nodes having a hierarchical structure in a tree shape.

The display unit 70 displays the display image formed by the image forming unit 60. A preferred specific example of the display unit 70 is a display device such as a display. The display unit 70 is not an essential configuration of the display processing device 100. For example, when the display processing device 100 does not include the display unit 70, the display image formed by the image forming unit 60 may be displayed on a display device or the like connected to the display processing device 100 as an external device. ..

The movement control unit 80 controls to move the data (file) to the node selected as the movement destination. The movement control unit 80 moves, for example, a file (data) designated by the user to a movement destination designated by the user from among a plurality of nodes managed in a hierarchical structure.

The display processing device 100 can be realized by using, for example, a computer. The computer is a display of a computing device such as a CPU, a storage device such as a memory or a hard disk, a communication device using a communication line such as the Internet, a device that reads data from a storage medium such as an optical disk or a semiconductor memory, and writes data, a display, or the like. It has hardware resources such as devices and operation devices that accept operations from users.

Then, for example, a program (software) corresponding to at least a part of the functions of the coded plurality of parts of the display processing apparatus 100 shown in FIG. 1 is read into the computer, and the hardware resources and the hardware resources of the computer are read. In cooperation with the software, at least a part of the functions of the display processing device 100 are realized by the computer. The program may be provided to a computer (display processing device 100) via a communication line such as the Internet, or may be stored in a storage medium such as an optical disk or a semiconductor memory and provided to the computer (display processing device 100). May be done.

The overall configuration of the display processing device 100 shown in FIG. 1 is as described above. Next, the functions and the like realized by the display processing apparatus 100 of FIG. 1 will be described in detail. For the configuration (part) shown in FIG. 1, the reference numerals in FIG. 1 are used in the following description.

FIG. 2 is a diagram showing a specific example of a plurality of nodes having a hierarchical structure. FIG. 2 shows a specific example of a hierarchical structure in which folders are nodes. That is, the hierarchical structure of the parent-child relationship in which the child folders and files exist in the parent folder (under the parent folder) is shown.

Of the plurality of nodes having a hierarchical structure, the node at the top layer is called a root, and the node at the bottom layer (end) is called a leaf. In addition, there may be a plurality of child folders (which may be files) in the parent folder. Multiple folders and files that have the same parent folder are siblings.

The hierarchical structure management unit 20 manages a plurality of files stored in the data storage unit 10 in a hierarchical structure having folders (or files) as nodes, for example, as in the specific example shown in FIG.

Further, the access authority management unit 30 determines whether or not the user can access the node (folder or file corresponding to the node) for each node (folder or file) of the plurality of nodes managed in the hierarchical structure, for example. Whether it is available or not) is managed.

In the specific example of the hierarchical structure illustrated in FIG. 2, the folder F11 is an inaccessible node, and the other folders and files are accessible nodes. Therefore, the user who has been given the access authority corresponding to the specific example shown in FIG. 2 accesses (expands the folder) the folder F12 in the lower layer of the folder F0 which is the root node (top layer node), and further, the folder F12. You can access (use the file) the file F22 in the lower layer. That is, the file F22 can be used by stepwise access that traces the lower layer nodes one after another from the uppermost layer node.

FIG. 3 is a diagram showing a specific example of stepwise access. FIG. 3 illustrates a specific example of stepwise access that traces a node accessible from the root node folder F0 to the file F22 via the folder F12 in the hierarchical structure of FIG. In the hierarchical structure illustrated in FIG. 2, when the stepwise access from the folder F0 to the file F22 via the folder F12 is performed, the image forming unit 60 displays, for example, a display image showing the partial hierarchical structure illustrated in FIG. Form.

On the other hand, in the specific example of the hierarchical structure illustrated in FIG. 2, since the folder F11 is an inaccessible node, the user who is given the access authority corresponding to the specific example shown in FIG. 2 is the root node (top layer node). ) Cannot access (expand the folder) the folder F11 under the folder F0. However, in the specific example shown in FIG. 2, the folders F21 under the inaccessible folder F11, the folders F31 and F32 under the folder F31, and the files F41 and F42 under the folder F31 are accessible nodes. Is.

When the user wants to access an accessible node (for example, folders F21, F31, F32, files F41, F42) below the inaccessible node (for example, folder F11), the user specifies the link information of the node to be accessed. do. For example, when the user inputs the path (for example, URL) of the folder or file to be accessed, the file or folder corresponding to the path is designated as the target node to be accessed, and the instruction receiving unit 40 accepts the designation of the target node.

In the specific example of the hierarchical structure illustrated in FIG. 2, when the user inputs the link information (for example, URL) of the file F41 using, for example, an operation device, the file F41 is designated as the target node, and the user directly enters the file F41. The file F41 can be used by accessing the file.

FIG. 4 is a diagram showing a specific example of direct access. FIG. 4 illustrates a specific example of direct access to an accessible target node in the hierarchical structure of FIG.

In the direct access, the instruction receiving unit 40 acquires the link information from the user to the target node via the operation device or the like. This specifies the target node. In the specific example shown in FIG. 4, the file F41 is designated as the target node by the user inputting the link information (for example, URL) of the file F41 using, for example, an operation device or the like.

When the target node is specified, the node search unit 50 searches for a node accessible to the user who specified the target node in the plurality of nodes managed in the hierarchical structure. The node search unit 50 searches for accessible nodes adjacent to each other in the hierarchical structure, starting from the target node designated by the user, for example.

When the file F41 is designated as the target node in the specific example shown in FIG. 4 (hierarchical structure of FIG. 2), the folder F31 is searched as an accessible node adjacent to the file F41 starting from the file F41, and the folder F31 is searched. The file F42 and the folder F21 are searched as adjacent accessible nodes, and the folder F32 is searched as an accessible node adjacent to the folder F21. Note that the folder F11 is not searched because it is a folder adjacent to the folder F21 (hierarchical structure in FIG. 2) but is not accessible.

In the direct access, the image forming unit 60 forms a display image showing the hierarchical structure of the target node group composed of the accessible nodes searched by the node search unit 50 and the target note. When the file F41 is designated as the target node in the specific example shown in FIG. 4, the file F41 which is the target node and the files F42, folders F31, F32, and F21 searched by the node search unit 50 become the target node group.

When the uppermost node of the hierarchical structure is not included in the target node group, the image forming unit 60 forms a temporary node in the lower layer of the uppermost node, and sets the hierarchical structure of the target note group in the lower layer of the temporary node. Form the display image to be shown. In the specific example shown in FIG. 4, when the file F41 is specified as the target node, the files F41, F42, folders F31, F32, and F21 become the target node group, and the folder F0 of the uppermost node is included in the target node group. Not included. Therefore, in the specific example shown in FIG. 4, when the file F41 is specified as the target node, a temporary folder (Ftmp), which is a specific example of the temporary node, is formed in the lower layer of the folder F0 of the uppermost node. A display image showing the hierarchical structure of the files F41, F42, folders F31, F32, and F21, which are the target node group, is formed in the lower layer of the temporary folder.
In the specific example shown in FIG. 4 (hierarchical structure of FIG. 2), there is one inaccessible folder (inaccessible folder) (only folder F11), but the number of inaccessible folders is not limited to one. It may be. For example, when a plurality of inaccessible folders are adjacent to each other, the plurality of inaccessible folders (multiple nodes) may be put together to form one temporary folder (temporary node). Further, for example, a temporary folder (temporary node) may be formed for each inaccessible folder according to a hierarchical structure without grouping the plurality of inaccessible folders (plural nodes).

Further, in the specific example shown in FIG. 4, the file F22 can be designated as the target node by the user inputting the link information (for example, URL) of the file F22 by using, for example, an operation device or the like. That is, the user can also directly access the file F22.

In the specific example shown in FIG. 4 (hierarchical structure of FIG. 2), when the file F22 is specified as the target node, the node search unit 50 searches the folder F12 as an accessible node adjacent to the file F22, and the folder F12 is searched. Folder F0 is searched for as an accessible node adjacent to. As a result, the files F22, folders F12, and F0 become the target node group.

When the uppermost node of the hierarchical structure is included in the target node group, the image forming unit 60 forms a display image including the hierarchical structure from the uppermost node to the target node. In the specific example shown in FIG. 4, when the file F22 is specified as the target node, the folder F0 of the uppermost node is included in the files F22, folders F12, and F0 constituting the target node group. Therefore, in the specific example shown in FIG. 4, when the file F22 is designated as the target node, a display image showing the hierarchical structure from the folder F0 of the uppermost node through the folder F12 to the file F22 is formed.

Further, the image forming unit 60 forms a selected image used in the movement of data by the movement control unit 80. The movement control unit 80 controls to move the data (file) to the node selected as the movement destination. The movement control unit 80 moves, for example, a file (data) designated by the user from a plurality of nodes (folders) managed in a hierarchical structure to a movement destination designated by the user. When the user specifies a movement destination, the image forming unit 60 forms a selected image showing the nodes included in the target node group as candidates for the moving destination.

The image forming unit 60 forms a display image corresponding to the specific example shown in FIG. 4, for example, as a selection image used when the user specifies a moving destination. That is, a temporary folder (Ftpp) is formed in the lower layer of the folder F0 of the uppermost node, and the hierarchical structure of the files F41, F42, folders F31, F32, and F21 which are the target node group is shown in the lower layer of the temporary folder. Form a display image (selected image).

The user selects a data movement destination while looking at the selected image formed by the image forming unit 60 and displayed on the display unit 70. For example, if the display image corresponding to the specific example shown in FIG. 4 is displayed as the selected image, the user can use the target node group (files F41, F42, folders F31, F32, F21) shown in the lower layer of the temporary folder. Select the destination to move the data from. For example, one of the folders F31, F32, and F21 is selected as the destination for moving the data (file). In the specific example shown in FIG. 4, for example, the folder F0 of the uppermost layer node or the folder F12 of the lower layer thereof may be selected as the move destination.

Then, the movement control unit 80 moves the data (file) to the node (folder) selected by the user from the candidates shown in the selected image. The data (file) to be moved may be data included in the hierarchical structure of FIG. 4 or data not included in the hierarchical structure of FIG.

FIG. 5 is a diagram showing a specific example of a display image (selected image) formed by the image forming unit 60. FIG. 5 shows a specific example of a display image (selected image) corresponding to the specific example (hierarchical structure of FIG. 2) shown in FIG.

For example, when the file F41 is designated as the target node in the specific example shown in FIG. 4 (hierarchical structure of FIG. 2), the file F41 which is the target node and the files F42, folders F31, and F32 searched by the node search unit 50, Since F21 is the target node group and the folder F0 of the top layer node is not included in the target node group, a temporary folder is formed in the lower layer of the folder F0 of the top layer node, and the temporary folder is in the lower layer. , The display image of FIG. 5 showing the hierarchical structure of the files F41, F42, folders F31, F32, and F21, which are the target node group, is formed.

Further, when the file F22 is designated as the target node in the specific example shown in FIG. 4 (hierarchical structure of FIG. 2), the target node file F22 and the folders F12 and F0 searched by the node search unit 50 are the target node group. Since the target node group includes the folder F0 of the uppermost node, the display image of FIG. 5 showing the hierarchical structure from the folder F0 of the uppermost node through the folder F12 to the file F22 is formed.

FIG. 5 shows a hierarchical structure from the folder F0 of the top-level node to the file F22 via the folder F12 even when a stepwise access is performed by tracing a node that can access the file F22 from the folder F0 via the folder F12. The display image of is formed.

Further, the display image illustrated in FIG. 5 may be used as a selection image used when the user specifies a movement destination. The user selects a data movement destination while looking at the selected image illustrated in FIG. 5, for example. For example, from the target node group (files F41, F42, folders F31, F32, F21) shown in the lower layer of the temporary folder, one of the folders F31, F32, and F21 is selected as the move destination of the data (file). be able to. Of course, the folder F0 of the uppermost layer node or the folder F12 of the lower layer thereof may be selected as the move destination.

FIG. 6 is a diagram showing a comparative example of direct access. FIG. 6 illustrates a comparative example of direct access to the accessible target node in the hierarchical structure of FIG.

In the comparative example shown in FIG. 6, when the user specifies the file F41 by inputting the link information (for example, URL) of the file F41 using, for example, an operation device, the folder F0 which is the root node (top layer node) is used. A virtual folder (Fim) is formed separately from the hierarchical structure up to the file F22, and a hierarchical structure showing only the file F41 is formed directly under the virtual folder.

Therefore, for example, in the display image corresponding to the comparative example shown in FIG. 6, the user cannot see the hierarchical structure of the target node group (files F41, F42, folders F31, F32, F21) in FIG. Further, when the display image corresponding to the comparative example shown in FIG. 6 is displayed as the selected image, the user selects the folders F31, F32, and F21 included in the target node group in FIG. 4 as the move destination. Can't.

On the other hand, according to the specific example described with reference to FIGS. 2 to 5, an accessible node (for example, file F41) below the inaccessible node (for example, folder F11) is designated as the target node. When this is done, a temporary folder is formed in the lower layer of the uppermost node (for example, folder F0), and the hierarchy of the target node group (for example, files F41, F42, folders F31, F32, F21) is formed in the lower layer of the temporary folder. A display image or a selection image showing the structure is formed. Therefore, the user can see the hierarchical structure of the target node group, and can select the destination of the data (file or folder) from the hierarchical structure of the target node group as needed. Further, for example, when there is a temporary node in the hierarchical structure, data can be moved between the node group in the upper layer and the node group in the lower layer of the temporary node.

FIG. 7 is a diagram (flow chart) showing a specific example of the processing executed by the display processing apparatus of FIG. First, the instruction receiving unit 40 accepts the designation of the target node by direct access for acquiring the link information from the user to the target node via the operation device or the like (S1).

When the target node is specified, the node search unit 50 searches for a node accessible to the user who specified the target node in the plurality of nodes managed in the hierarchical structure (S2). The node search unit 50 searches for accessible nodes adjacent to each other in the hierarchical structure, starting from the target node designated by the user, for example.

Then, in the search by the node search unit 50, it is confirmed whether or not the root node can be searched (S3).

If the root node (top layer node) can be searched as a result of searching for accessible nodes adjacent to each other in the hierarchical structure starting from the target node, the root node is included in the target node group. In this case, the hierarchical structure of the target node group is displayed in the lower layer of the root node (S4).

On the other hand, if the root node (top layer node) cannot be searched as a result of searching for accessible nodes adjacent to each other in the hierarchical structure starting from the target node, the target node group does not include the root node. For example, if there is an inaccessible node between the target node group searched starting from the target node and the root node, the adjacency relationship of the accessible nodes is interrupted and the root node cannot be searched. In this case, a temporary folder is created in the lower layer of the root node (S5), and the hierarchical structure of the target node group is displayed in the lower layer of the temporary folder (S6).

If, for example, a temporary folder has already been formed as a result of the target node being specified in the past at the start of processing in S5, a new target node will be added to the lower layer of the already formed temporary folder. The hierarchical structure of the corresponding target node group may be displayed.

Although the preferred embodiments of the present invention have been described above, the above-described embodiments are merely examples in all respects, and do not limit the scope of the present invention. The present invention includes various modified forms without departing from its essence.
