Abstract

A virtual folder construction apparatus is provided that allows a user to operate without being aware of the setting of a file that belongs to or excludes from a virtual folder regardless of a search condition expression.
A virtual folder definition unit sets a search condition expression based on metadata for generating a virtual folder. The content operation unit 104 generates an addition / deletion content list indicating the content ID of the content to be added to or deleted from the virtual folder regardless of the search condition formula. The virtual folder information output unit 103 combines the search condition expression defined by the virtual folder definition unit 105 and the content ID of the content specified as the addition or deletion target by the content operation unit 104, and extracts additional content. At the same time, a new search condition expression that does not extract the deleted content is created. The content management system 109 searches for content based on the new search condition formula.

Description

  The present invention relates to a technique for constructing a virtual folder.

As a method of presenting files and folders (directories) to users from different viewpoints (views) rather than a physical file system configuration on the disk, the conventional virtual folder system uses search conditions based on file metadata as virtual folders. By defining and using the search result of the file based on the search condition when referring to the virtual folder, a virtual folder system based on the classification according to the search condition has been realized (for example, Patent Document 1).
In addition, a method for dynamically specifying a search condition for a virtual folder at the time of folder operation and a method for realizing a file move / copy operation between virtual folders by updating file metadata have been proposed (for example, Patent Document 2).
JP 2003-323326 A JP-T-2006-521594

In the conventional virtual folder system, files belonging to a virtual folder are defined by a search condition formula that uses file metadata, so the metadata set in the file corresponds to the search condition formula for multiple virtual folders In this case, the file belongs to a plurality of virtual folders.
For example, if a virtual folder is defined for each document creator with respect to a file group in which the document creator is defined as metadata, the document file co-authored by multiple creators belongs to each creator's virtual folder. Will be.
When setting a file belonging to multiple virtual folders to belong to only one virtual folder, it is not possible to change the metadata contents (delete other co-authors) For this reason, it is necessary to take individual measures such as changing the search condition formula so that the file does not meet the conditions for the virtual folder from which the file is excluded from belonging.
Therefore, it is necessary for the user (operator) to know the definition contents of the virtual folder and the information about the file metadata, and if the number of files and virtual folders is large, the search condition formula of the virtual folder is corrected. There was a problem that the individual work required increased.

Although excluded in the search condition formula of the virtual folder, the same problem occurs when adding a file to be included in the virtual folder.
For example, for a file group in which the file management department is defined as metadata, the management department of the regular file and the business management department related to the file are the same, and a virtual folder is defined for each management department If you want to assign an exceptional file with a different file and business management department to the virtual folder of the business management department, you cannot change the file metadata (file management department), so file management The search condition formula for the department virtual folder and the search condition formula for the business management department virtual folder must be changed separately.
That is, when a file management department is defined as metadata, according to the search condition formula based on metadata, for example, only a file group in which metadata is described as A department as a management department in the metadata is a virtual group related to A department. It will be included in the folder. However, if the file is related to the business of department A, there may be a case where a file in which department B is described as a management department in the metadata is also included in the virtual folder of department A. In such a case, since the file metadata (file management department) cannot be changed, the search condition formula can be individually handled so that the file managed by department B is included in the virtual folder of department A. I need it.

  As described above, when the virtual folder search condition formula is considered as a file classification condition, when handling exceptional files outside the classification condition in the virtual folder system, the file metadata can be changed and handled. Because it is not possible, it is necessary to modify the search condition formula of the virtual folder for each exceptional file, the user needs to have knowledge about the definition of the virtual folder and the file metadata information, and the work is complicated. There was a problem of becoming.

  The main object of the present invention is to solve the above-described problems, and it is possible to set a file to belong to a virtual folder or to be excluded from a virtual folder regardless of the result of a search condition expression defined in the virtual folder. The main object is to obtain a virtual folder construction device that can be operated without the user's awareness.

The virtual folder construction device according to the present invention is:
A first search condition designating unit for designating a search condition for searching for a file included in the virtual folder as a first search condition;
Designate at least one of an additional file to be included in the virtual folder independent of the search based on the first search condition and an excluded file to be excluded from the virtual folder independent of the search based on the first search condition A file specification part;
A new search for searching for a file to be included in the virtual folder, using the first search condition specified by the first search condition specifying unit and the identification information of the file specified by the file specifying unit. And a second search condition designating unit that generates a condition as a second search condition.

  According to the present invention, the identification information of the added file and the deleted file is added to the first search condition so that the added file is included in the virtual folder and the deleted file is not included in the virtual folder. Since the search condition is generated, the user does not need to correct the search condition expression, and a complicated operation is not necessary, and a setting error of the search condition expression can be avoided.

Embodiment 1 FIG.
FIG. 1 is a functional configuration diagram illustrating an example of a virtual folder construction device 101 according to the present embodiment and its peripheral functional elements.
In FIG. 1, an application 100 is software that uses a virtual folder using the virtual folder construction apparatus 101 (for example, software having a function like an Explorer of Windows (registered trademark)).
The virtual folder construction apparatus 101 is a system that provides a virtual folder tree (a hierarchical arrangement of virtual folders) for a content (file + metadata) set managed by the content management system 109.
The input / output processing unit 102 is a unit that provides an application program interface (API) to the application 100 so that the application 100 can operate the virtual folder tree.
The virtual folder information output unit 103 is a unit that collects necessary data from the content management system 109 and the repository 110 in accordance with a request from the input / output processing unit 102 and constructs information.
The content operation unit 104 is a unit that processes content operations in the virtual folder tree in accordance with a request from the input / output processing unit 102.
The virtual folder definition unit 105 is a unit that performs a virtual folder tree definition process in accordance with a request from the input / output processing unit 102.
The DB access unit 106 is a means for performing access processing to the repository 110.
A content management system (CMS) access unit 107 is a means for performing access processing to the content management system 109.
The CMS-API 108 is an API for executing processing in the content management system 109.
The content management system 109 is a system that stores and manages files that provide views using a virtual folder tree.
The repository 110 is a database that stores and manages various types of information used by the content management system 109, and also stores and manages information used by the virtual folder construction apparatus 101.

The input / output processing unit 102 provides the application 100 with a virtual folder list function, a virtual folder definition function, a content addition function, a content deletion function, and a content list function as operations on the virtual folder tree.
By combining these functions, the application 100 can realize a virtual folder tree operation function.
For example, the virtual folder list function can be used to display the entire virtual folder tree, the virtual folder definition function can be used to create a virtual folder, and the content list function can be displayed separately from a virtual folder. The content can be moved to the virtual folder by combining the content deletion function and the content addition function.
The input / output processing unit 102 may further provide other functions such as a virtual folder deletion function.

In the content management system 109, files to be operated by the virtual folder tree are centrally managed.
A combination of a file and metadata of the file is defined as content, and an operation environment in which the content is an operation unit is provided.
In the content management system 109, a unique content ID is assigned to the content, and the content is managed by the content ID. Content operations include content registration and deletion in the content management system 109 and content search using metadata. These operations use the CMS-API 108 in addition to the interactive operation interface by the user. It can be executed from a software program.

  In the repository 110, in addition to the data used by the content management system 109, folder definition information and added / deleted content lists are created and used by the virtual folder construction apparatus 101.

The virtual folder definition unit 105 specifies a search condition expression (first search condition) for searching for contents (files) included in the virtual folder.
Specifically, the virtual folder definition unit 105 specifies a search condition expression regarding the content of metadata added to a file.
The virtual folder definition unit 105 is an example of a first search condition designation unit.

The content operating unit 104 deletes additional content (additional file) to be included in the virtual folder and excluded from the virtual folder independently of the search based on the search condition formula (first search condition) defined by the virtual folder definition unit 105 Specify at least one of the contents (excluded files).
The content operation unit 104 designates any content that does not match the search condition formula defined by the virtual folder definition unit 105 as additional content, and any content that matches the search condition formula defined by the virtual folder definition unit 105 Designate content as deleted content.
The content operation unit 104 is an example of a file designation unit.

The virtual folder information output unit 103 uses the search condition expression (first search condition) defined by the virtual folder definition unit 105 and the content identification information specified by the content operation unit 104 to be included in the virtual folder. A new search condition expression (second search condition) for content search is generated.
Specifically, the virtual folder information output unit 103 combines the search condition expression (first search condition) specified by the virtual folder definition unit 105 and the content identification information specified by the content operation unit 104, In the search in the content management system 109 (file management system), content that matches the search condition formula (first search condition) and additional content specified by the content operation unit 104 are extracted and specified by the content operation unit 104 A search condition expression (second search condition) from which the deleted content is not extracted is generated.

In addition, in the repository 110 (file identification information registration device), an addition / deletion content list indicating identification information of additional content or deletion content designated by the content operation unit 104 is registered.
Further, the input / output processing unit (input unit) of the virtual folder construction apparatus 101 requests the content operation unit 104 to specify specific content as additional content for the specific virtual folder (additional file specification). Request) or a deleted content designation request (exclusion file designation request) for requesting the content operation unit 104 to designate a specific content as a deleted content for a specific virtual folder.
When the input content specifying request is input by the input / output processing unit 102, the content operating unit 104 deletes content that is specified as additional content in the additional content specifying request for a specific virtual folder in the repository 110. If the content is registered as deleted content for a specific virtual folder, the identification information of the deleted content is deleted from the added / deleted content list of the repository 110, and The content registered as the deleted content is not designated as the deleted content.
Further, the content operation unit 104, when a deletion content designation request is input by the input / output processing unit 102, the content requested to be designated as the deletion content in the deletion content designation request corresponds to a specific virtual folder in the repository 110. It is determined whether or not it is registered as additional content, and when the content is registered as additional content for a specific virtual folder, the identification information of the additional content is deleted from the added / deleted content list of the repository 110. The content registered as the additional content is not designated as the additional content.

FIG. 2 is a data record format diagram showing an example of folder definition information created by the virtual folder construction apparatus 101.
In FIG. 2, a folder ID 120 is a virtual folder identifier in the virtual folder construction apparatus 101.
The folder name 121 is the name of the virtual folder.
The parent folder ID 122 is the folder ID of the upper folder in the virtual folder tree of the virtual folder represented by the folder ID 120.
The search condition expression 123 is a search condition expression using metadata for searching for contents belonging to the virtual folder represented by the folder ID 120. The search condition expression 123 is an example of a first search condition.

When the virtual folder is a root folder (the highest folder in the virtual folder tree), the parent folder ID 122 is set to a special fixed value different from the normal folder ID value (for example, the root ID is set as a positive integer). The parent folder ID of the folder is set to −1).
In addition to the folder ID 120, the folder name 121, the parent folder ID 122, and the search condition expression 123, the folder definition information may include additional information data items.

FIG. 3 is a data record format diagram showing an example of an addition / deletion content list created by the virtual folder construction apparatus 101.
The folder ID 130 is a folder ID to be operated.
The operation type 131 is data indicating a content adding operation or a deleting operation.
The content ID 132 is a content ID (identification information) of content to be added to or deleted from the virtual folder indicated by the folder ID 130.
The added / deleted content list may include a data item of additional information in addition to the folder ID 130, the operation type 131, and the content ID 132.
In addition, the folder definition information and the added / deleted content list may be stored and managed using a database management system different from the repository 110, instead of being stored and managed in the repository 110 used by the content management system 109. .

Next, an operation example (virtual folder construction method) of the virtual folder construction apparatus 101 according to the present embodiment will be described.
First, the overall flow will be described with reference to FIG.
First, in step S1001, the virtual folder definition unit 105 performs a virtual folder definition process (first search condition specifying step).
In other words, a virtual folder creation is requested by designating a folder ID of a virtual folder newly created by the application 100, a search condition expression, and the like, and the virtual folder definition unit 105 is based on a request from the application 100 and becomes a target folder ID. The search condition formula 123 and the like are set in the URL, and a new record is added to the folder definition information of the repository 110 using the DB access unit 106.
Details of the virtual folder definition process will be described later with reference to FIG.

Next, in step S1002, the content operation unit 104 performs content addition processing and / or content deletion processing (file designation step).
That is, the application 100 designates the content ID of the content to be added or deleted and the folder ID of the virtual folder of the addition destination / deletion destination, and outputs an addition content designation request or a deletion content designation request. Based on the request from 100, an addition / deletion content list indicating the target content ID is generated / updated, and the DB access unit 106 is used to add the addition / deletion content list to the repository 110.
Details of the content addition process and the content deletion process will be described later with reference to FIGS.

Next, in step S1003, the virtual folder information output unit 103 performs content list processing (second search condition designation step).
That is, the virtual folder information output unit 103 combines the search condition formula defined by the virtual folder definition unit 105 and the content ID (identification information) of the content specified as the addition or deletion target by the content operation unit 104, Create a new search condition expression (second search condition expression).
In addition, the content management system 109 searches for content based on the new search condition expression generated by the virtual folder information output unit 103.
Details of the content list process will be described later with reference to FIG.

Next, the flow of virtual folder definition processing in the virtual folder construction apparatus 101 will be described with reference to the flowchart of FIG.
FIG. 4 is a flowchart showing the virtual folder definition procedure (first search condition designation step) of the present embodiment.
In step S140, the application 100 designates the folder ID and folder name of the virtual folder where the new folder is to be created, and the search condition expression in the new folder, and executes a virtual folder creation request using the API of the input / output processing unit 102.
In step S141, the input / output processing unit 102 requests the virtual folder definition unit 105 to perform processing.
The virtual folder definition unit 105 assigns a new folder ID, assigns the folder ID assigned to the folder ID 120 as the record of the folder definition information, the folder name 121 indicates the folder name, the parent folder ID 122 indicates the creation destination folder ID, and the search condition formula A search condition formula is set in 123, and a new record is added to the folder definition information in the repository 110 using the DB access unit 106.
In step S <b> 142, the input / output processing unit 102 receives the processing result from the virtual folder definition unit 105 and returns the result to the application 100.
From the above, a virtual folder is defined by the application 100 in the virtual folder construction apparatus 101.

The flow of content addition processing to the virtual folder in the virtual folder construction apparatus 101 will be described with reference to the flowchart of FIG.
FIG. 5 is a flowchart showing a content addition procedure (file designation step) to the virtual folder according to the present embodiment.
In step S150, the application 100 designates the content ID of the content to be added and the folder ID of the destination virtual folder, and designates the additional content for requesting addition of the content to the virtual folder using the API of the input / output processing unit 102. Output the request.
In step S151, the input / output processing unit 102 that has input the additional content designation request requests the content operation unit 104 to perform processing.
The content operation unit 104 accesses the addition / deletion content list in the repository 110 using the DB access unit 106, the folder ID 130 is the folder ID of the addition destination folder, the operation type 131 is deletion, and the content ID 132 is the content of the additional content. The record that is the ID (deleted record) is searched.
In step S152, if there is a deletion record, the process proceeds to step S153, and if not, the process proceeds to step S154.
In step S153, the content operation unit 104 accesses the addition / deletion content list in the repository 110 using the DB access unit 106, and deletes the deleted record searched in step S151. The existence of a deletion record means that the extraction of the additional content is excluded by the deletion record because the additional content has the property of being extracted by a normal search based on a search condition expression if there is no deletion record. . For this reason, if the deletion record is deleted, the additional content is extracted by a normal search based on the search condition formula.
In step S154, the content operation unit 104 uses the DB access unit 106 to access the repository 110, with the record having the folder ID 130 as the folder ID of the addition destination folder, the operation type 131 as the addition, and the content ID 132 as the content ID of the additional content. To add to the added / deleted content list.
In step S <b> 155, the input / output processing unit 102 receives the processing result from the content operation unit 104 and returns the result to the application 100.
As described above, content is added to the virtual folder by the application 100 in the virtual folder construction apparatus 101.

The flow of content deletion processing from the virtual folder in the virtual folder construction apparatus 101 will be described with reference to the flowchart of FIG.
FIG. 6 is a flowchart showing a content deletion procedure (file designation step) from the virtual folder according to the present embodiment.
In step S160, the application 100 designates the content ID of the content to be deleted and the folder ID of the deletion destination virtual folder, and uses the API of the input / output processing unit 102 to request deletion of the content from the virtual folder. Output the request.
In step S161, the input / output processing unit 102 that has input the deletion content designation request requests the content operation unit 104 to perform processing.
The content operation unit 104 accesses the addition / deletion content list in the repository 110 using the DB access unit 106, the folder ID 130 is the folder ID of the deletion destination folder, the operation type 131 is added, and the content ID 132 is the content ID of the deletion content. Search for records that are (additional records).
In step S162, if an additional record exists, the process proceeds to step S163, and if not, the process proceeds to step S164.
In step S163, the content operation unit 104 accesses the addition / deletion content list in the repository 110 using the DB access unit 106, and deletes the added record searched in step S161. The presence of an additional record means that the deleted content is extracted by the additional record because the deleted content has a property that it cannot be extracted by a normal search based on the search condition formula without the additional record. Therefore, if an additional record is deleted, the deleted content is not extracted by a normal search using a search condition expression.
In step S164, the content operation unit 104 uses the DB access unit 106 to access the repository 110, with the record having the folder ID 130 as the folder ID of the deletion destination folder, the operation type 131 as the deletion ID, and the content ID 132 as the content ID of the deletion content. To add to the added / deleted content list.
In step S165, the input / output processing unit 102 receives the processing result from the content operation unit 104 and returns the result to the application 100.
From the above, content is deleted from the virtual folder by the application 100 in the virtual folder construction apparatus 101.

The flow of content list information acquisition processing of the virtual folder in the virtual folder construction apparatus 101 will be described with reference to the flowchart of FIG.
FIG. 7 is a flowchart showing the contents list information acquisition procedure of the virtual folder according to the present embodiment.
In step S170, the application 100 designates the folder ID of the virtual folder from which content list information is to be acquired, and executes a content list information acquisition request using the API of the input / output processing unit 102.
In step S171, the input / output processing unit 102 requests the virtual folder information output unit 103 to perform processing. The virtual folder information output unit 103 accesses the folder definition information in the repository 110 using the DB access unit 106, searches for a record in which the value of the folder ID 120 matches the folder ID specified as the content list acquisition target, The search condition expression 123 is taken out.
In step S172, the virtual folder information output unit 103 uses the DB access unit 106 to access the added / deleted content list in the repository 110, and the value of the folder ID 130 matches the folder ID designated as the content list acquisition target. Search for records and retrieve results.
In step S173, if the record of the search result in step S172 exists, the process proceeds to step S174, and if not, the process proceeds to step S175.
In step S174, the virtual folder information output unit 103 uses the search condition expression 123 acquired in step S171 and the search condition record for adding / deleting content list acquired in step S172 to search for content belonging to the virtual folder. The expressions are synthesized (second search condition specifying step).
In step S175, the virtual folder information output unit 103 uses the CMS access unit 107 to inquire the content management system 109 about content corresponding to the search condition formula.
In step S 176, the CMS access unit 107 acquires information (content ID, content name, etc.) necessary for the content list for the content corresponding to the search condition formula using the CMS-API 108, and returns it to the virtual folder information output unit 103.
The input / output processing unit 102 receives content list information from the virtual folder information output unit 103 and returns a result to the application 100.
From the above, the application 100 can acquire list information of contents belonging to an arbitrary virtual folder by the virtual folder construction apparatus 101.

A method of synthesizing the search condition formula from the search condition formula 123 of the folder definition information and the search result record of the addition / deletion content list in step S174 will be described with reference to FIG.
FIG. 8 is an explanatory diagram for explaining a method (second search condition specifying step) for synthesizing the search condition formula and the addition / deletion content list according to this embodiment.

In FIG. 8, folder definition information 180 is an example of folder definition information when the folder ID is 1208. The matter shown in the item of the search condition formula is the first search condition.
The added / deleted content list 181 is an example of an added / deleted content list when the folder ID is 1208.
The combined search condition expression 182 (second search condition) is an example of a search condition expression combined from the folder definition information 180 and the added / deleted content list 181.
The search condition formula is synthesized by creating and adding a condition to the search condition formula of the folder definition information 180 based on the record in the added / deleted content list 181.
When the operation type of the addition / deletion content list 181 is addition, a condition for searching for the content having the content ID of the record is added by an OR condition.
When the operation type is deletion, a condition for searching for content that does not have the content ID of the record is added using an AND condition.
In the case of a virtual folder with a folder ID of 1208, there are one added record and two deleted records in the added / deleted content list 181. Therefore, an OR condition is created from the added record, and an AND condition is created from the removed record to define the folder. When added to the search condition expression of the information 180, a combined search condition expression 182 can be created.

The flow of the virtual folder list process in the virtual folder construction apparatus 101 will be described with reference to the flowchart of FIG.
FIG. 9 is a flowchart showing the virtual folder list procedure of the present embodiment.
In step S190, the application 100 designates the folder ID of the virtual folder or a value indicating the root folder (such as no designation or a fixed value for the root folder), and uses the API of the input / output processing unit 102 to list the virtual folder. Execute the request.
In step S191, the input / output processing unit 102 requests the virtual folder information output unit 103 to perform processing. If the folder ID is specified in step S190, the virtual folder information output unit 103 sets the folder ID as a subfolder information acquisition target folder ID to step S193, and if it is a value indicating the root folder, the virtual folder information output unit 103 proceeds to step S192.
In step S192, the virtual folder information output unit 103 accesses the repository 110 using the DB access unit 106, and searches the folder definition information for records whose parent folder ID is a fixed value for the root folder. The folder ID 120 of the retrieved record is set as the folder ID for sub folder information acquisition.
In step S193, the virtual folder information output unit 103 accesses the repository 110 using the DB access unit 106, and searches the folder definition information for a record whose parent folder ID matches the folder ID of the subfolder information acquisition target. The virtual folder information output unit 103 creates virtual folder list information from the search result record.
In step S 194, the input / output processing unit 102 receives virtual folder list information from the virtual folder information output unit 103, and returns a result to the application 100.
From the above, the application 100 can acquire the list information of the subordinate virtual folders existing in an arbitrary virtual folder in the virtual folder construction apparatus 101.

  As described above, according to the virtual folder construction device according to the present embodiment, for the addition / deletion of content to / from the virtual folder, the search condition formula for searching the content belonging to the virtual folder is corrected. Therefore, it is not necessary for the user (application) to correct the search condition formula.

  Further, according to the virtual folder construction device according to the present embodiment, the user (application) does not use the content metadata information for operations other than the virtual folder definition. Even without knowing, it is possible to move / copy / delete contents between virtual folders.

Furthermore, according to the virtual folder construction device according to the present embodiment, content that is exceptionally handled with respect to the definition of the virtual folder is separately managed as an addition / deletion content list, and the virtual folder search condition expression definition itself By making no change, processing related to exceptional content can be simplified.
Further, by linking with the content management system via the API, it is possible to construct a system in an add-on format to the existing content management system without modifying the content management system.

As described above, in the present embodiment, in the virtual folder system that provides the folder tree from different viewpoints for the content managed by the content management system,
