Abstract

PROBLEM TO BE SOLVED: To accurately manage the classification attributes in terms of use or meaning of files and directories. SOLUTION: Logical classification name groups 3-A to 3-M linked to the substance of the files/directories A-M by a file descriptor 4 are provided with plural classification items 1-N and classification names showing the logical attributes of the files and directories are held in the respective classification items. At the time of receiving a reference instruction specifying a file name/ directory name from a user through an input device 1, a classification name extraction means 2-1 extracts the classification name in the logical classification name group linked by the file descriptor 4 of the file/directory and displays it at a display device 5. Though the classification in terms of the use or the meaning of the file and the directory is not accurately recognized just by the file name or the directory name, it is accurately recognized by referring to the logical classification name group and the maintenance and management of the files and the directories are facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a file management system, and more particularly to a file management system in which a plurality of logical attributes of a file and a directory are held in association with the entity of the file and the directory.

[0002]

2. Description of the Related Art In a conventional file management system, at the time of accessing a file, a file name specified by a user is translated and converted as a unique file name in all systems, and then translated into a unique physical name in all systems. Translation and conversion to a target storage location for actual access. Here, in the process of translating and converting a designated file name into a unique file name in all systems, the file management system has a file naming mechanism, and further uses a directory system as the file naming mechanism.

That is, the file name instructed to be accessed by the user is uniquely determined on the directory structure in the entire system, so that the physical storage location is also uniquely determined, and the access is realized here. Becomes In other words, conversely, in order for file access to be realized, the file name must be unique in all systems from the viewpoint of the directory structure in all systems, and similarly, the directory name must also be unique. Must.

In a conventional file management system, a method of designating a file / directory for which a user gives an access instruction is based on a directory structure in the entire system. Only the method of specifying the name is realized and provided.

Therefore, in such a conventional file management system, when giving a name to a file, the user takes into account the directory structure in the entire system and the name of the directory itself in which the file is located. , Or the name of the directory itself. In the first place, the background of the general adoption of the directory structure in the file management system is to provide the user with such a method as a premise, and to provide the user with the file / directory in the entire system of the directory system. The uniqueness of the name has been recognized as a benefit.

Now, in a conventional file management system,
In terms of file and directory management, it does not provide itself with any means of adding inherent unique uses or attributes for classification. Therefore, when giving a file / directory name, it is extremely inevitable for the user to give the name itself a unique semantic attribute for the original use / classification of the file / directory. It is an act.

However, in the file management system, the character length of the name is generally limited, and there are also characters that cannot be used as the name. It is common practice to give the name that was wanted or should be given by symbolized characters. Here, the original semantic uniqueness of the file / directory is, to a greater or lesser degree, replaced by symbolization, that is, the uniqueness of an abstracted name.

[0008]

In a conventional file management system, when the maintenance or management of the structure of a file / directory is considered, the file / directory name is derived from the above-mentioned abstracted file / directory name.
The original meaning of the use of the directory must be specified by tracing the reverse route from the thought in the order in which the file / directory names are given. This operation requires a longer time and a greater possibility of making an error than the operation of giving a name to a file / directory. This is because the act of naming files / directories is inherently an arbitrary task.

The most fundamental problem is that, as described above, in the conventional file management system, the assignment, change, and reference of the attribute of the file and directory for the original unique use or classification are performed. No means has been implemented, so users can only implicitly assign attributes for their own use / semantic classification to file and directory names only. is there.

An object of the present invention is not to use a conventional method of extracting files / directories by designating symbolized names of the files and directories when performing maintenance and management on the structures of the files and directories. Maintenance of file and directory structure by providing a method for extracting files / directories based on the meanings of files and directories held for usage and attributes for logical classification from the purpose of use And to improve the ease of management.

[0011]

According to the present invention, there is provided a classification name storage unit (FIG. 1) for storing a plurality of logical classification names, which are a plurality of logical attributes of a file and a directory, in association with file and directory entities. 3) and a classification name extracting means for extracting and outputting a logical classification name in a logical classification name group stored in the classification name storage unit in association with the file and directory specified by the reference instruction (FIG. 1-2-1). Also, when a file and directory are newly generated, an initial generation means (10 in FIG. 4) for generating an initial state logical classification name group for the file and directory in the classification name storage unit, and a registration instruction specified by the registration instruction. Classification name processing means (2 in FIG. 1) for registering a logical classification name in a logical classification name group stored in the classification name storage unit in relation to files and directories.
-2).

Further, the classification name extracting means of the present invention, when a logical classification name is given in the reference instruction as the information for specifying the file and directory to be referred to, is the same logical classification name as this logical classification name Is retrieved from the classification name storage unit, a logical classification name of a reference target designated by a reference instruction in the retrieved logical classification name group is extracted, and the retrieved logical It has a configuration for extracting the names of files and directories associated with a group of hierarchical names.

[0013] The initial generation means of the present invention may be further configured to convert a group of initial logical classification names for newly generated files and directories into a group of logical classification names associated with the source directory of the files and directories. Is generated by copying

Further, the present invention comprises a file transfer means for transferring a file entity by adding a logical category name group stored in the category name storage section in association with the file entity.

Still further, in a preferred embodiment of the present invention, files and directories are attached to
An input device (1 in FIG. 1) for inputting a classification name based on a logical classification item, or instructing extraction and processing of the classification item and the classification name, and linked to a file and a directory entity. A classification name storage unit (3 in FIG. 1) for storing classification names corresponding to logical classification items of files and directories; file and directory entities; and classification name groups corresponding to the entities in the classification name storage unit A file descriptor (4 in FIG. 1) holding a portion pointing to the storage area in the classification name storage classification for linking the file name, and a classification name in the classification name storage unit according to an instruction input from the input device. , A classification name processing means (2 in FIG. 1) for extracting and processing, and a display device (5 in FIG. 1) for displaying the processing result of the classification name processing means. .

Here, the meanings of "logical classification term" and "logical classification name" are as follows.

Logical category: a plurality of category categories assigned to files and directories, and includes category terms such as category 1, category 2, category 3,... It is also simply called a classification term. For example, if a user classifies files and directories related to a certain person belonging to a company from the organizational hierarchy, classification 1 = company name, classification 2
= Division name, classification 3 = division name, classification 4 = section name, classification 5 = staff, classification 6 = individual name, classification 7 = title, classification 8 = gender,
The meaning of the convenient classification according to the purpose of use, such as classification 9 = age, classification 10 = year of joining,..., Is appropriately given to the logical classification term.

(1) Logical classification name: a classification name given to a logical classification item. It may also be called a classification name or a classification name. In the above example, for example, category 1 = company name =
Tokyo Manufacturing Co., Ltd., Class 2 = Division name = First Manufacturing Division, Class 3 = Division name = Third Development Division, Class 4 = Section name = Planning Division, Class 5 = Section name = Development Section, Category 6 = Personal name = Taro Tokyo, Class 7 = Position name = Chief, Class 8 = Gender = Male, Class 9
= Age = 30 years, Class 10 = History = 1997,..., A logical classification name is given as a unique name to the right side of the equation along with the logical classification term.

[0019]

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a configuration diagram showing an example of an embodiment of the present invention, and shows an example of a configuration for managing files and directories by logical classification.

In this embodiment, the input device 1 includes a keyboard 1-1 and a pointing device 1-2. The keyboard 1-1 and the pointing device 1-2 are used for giving instructions such as assignment, deletion, change, and extraction of a classification name in the present invention.

The classification name processing means 2 includes a classification name extraction means 2
-1 and classification name processing means 2-2. The classification name extracting means 2-1 has a function of extracting a corresponding one from classification names in a classification name storage unit 3 described later. The classification name processing unit 2-2 processes the classification name extracted by the classification name extraction unit 2-1 according to the instruction given from the input device 1 described above.

The classification name storage unit 3 stores logical classification name groups 3 linked to the individual files and the entities of the directories A to M via a file descriptor 4 described later.
-A to 3-M. Further, the logical classification name groups 3-A to 3-M are respectively the classification name of the classification item 1,
.., And the classification name of the classification item N (3-A-1 to 3-AN, 3-B- in FIG. 1).
1-3-BN, ..., 3-M-1 to 3-MN). In addition, the logical classification name groups 3-A to 3-M provide themselves with an address 3--3 to the file descriptor to which they are assigned.
AA, 3-BA, ..., 3-MA are held. The number of classification items is determined in advance by the system.

The file descriptor 4 includes a logical classification name group 3 and a conventional file descriptor in order to link the entities of the files and directories A to M with the logical classification name groups 3-A to 3-M. -A-3
-Holds a part pointing to the storage area of M.

The display device 5 is a display 5-1, and displays the processing progress and the result in the classification name processing means 2.

Next, the operation of the present embodiment configured as described above will be described in detail for a case where a classification name is registered and a case where a classification name is referred to.

(1) Registration of Classification Name Registration of a classification name means adding a classification name to classification items 1 to N of a logical classification name group linked to a file / directory entity via a file descriptor. This means that the already added classification name is changed to another classification name. Note that deleting a classification name is equivalent to an operation of changing to a NULL value.

When registering a classification name, the user uses the keyboard 1-1 or the pointing device 1-2 of the input device 1 to specify a file or a directory in which the classification name is to be registered, and to specify the classification items 1 to 5. A classification item to be registered and a classification name to be registered therein are designated. At this time, the method of designating the file and directory to be registered includes: (a) a method of designating the name of the file and directory directly or by using a wild card (hereinafter referred to as a direct designation method) (b) Classification item There are two methods of specifying a classification name of n and a method of registering a file and a directory having a classification name matching the classification name (hereinafter, referred to as a classification name specification method). Further, in the classification name specification method (b), a target file / directory can be specified by a logical product or a logical sum as a combination of a plurality of classification items and classification names. Hereinafter, the classification item specified by the classification name specification method and the specification content of the classification name may be referred to as “extraction condition”.

The designation of a file / directory to be registered and the designation of a registration target classification item and a registration classification name (hereinafter referred to as a registration command) input from the input device 1 are passed to the classification name processing means 2. After checking the validity of the context of the received registration command, the classification name processing means 2 executes the registration process according to the flow shown in FIG.

First, the classification name processing means 2 determines whether the file and directory to be registered are specified directly or in a classification name (S1), and performs the following processing according to each specification method. Execute.

In the case of the direct designation method When the file / directory to be registered is designated by the direct designation method, first, the classification name extracting means 2-1 uses
The file descriptor of the file / directory specified by the direct specification method is referred to by the file access procedure in the conventional file management method (S2). The classification name extracting means 2-1 further refers to the corresponding logical classification name group from the storage position of the logical classification name group in the file descriptor, and searches for the classification name of the registration target classification item specified by the registration instruction. The storage address in the logical classification name group is extracted, and the extracted address is passed to the classification name processing means 2-2 (S3). When a plurality of classification items to be registered are designated, their storage addresses are extracted and transmitted to the classification name processing means 2-2.

Next, the classification name processing means 2-2 determines the contents indicated by the passed address (the original classification name (N
(Including the case of the UL value)) is changed to the classification name specified by the registration command (S4). And the classification name processing means 2
-2 displays the registration result on the display 5-1 (S
5). In the registration result displayed at this time, a classification item and a classification name registered for confirmation are displayed together with a message indicating that the registration has been completed.

Classification Name Designation Method When the file / directory to be registered is designated by the classification name designation method, the classification name extraction means 2-1 directly transmits the classification name storage unit 3 without passing through the file descriptor. , Searching for a logical classification name group that matches the extraction condition specified by the registration instruction, and, in the searched logical classification name group, the classification name of the registration target classification item specified by the registration instruction Then, the storage address in the group of logical classification names is extracted, and the extracted address is passed to the classification name processing means 2-2 (S6). When a plurality of classification items to be registered are designated, their storage addresses are extracted and transmitted to the classification name processing means 2-2.

Next, the classification name processing means 2-2 determines the contents indicated by the passed address (the original classification name (N
Is changed to the classification name designated by the registration command (S7). Next, classification name processing means 2-
2 obtains the name of the file / directory entity to which the logical classification name group depends on by following the address to the file descriptor to which the logical classification name group whose classification name has been changed is assigned (S8). Then, the classification name processing means 2-2 displays the registration result on the display 5-1 (S9). The registration result displayed at this time includes a message indicating that the registration has been completed, the classification item and the classification name registered for confirmation, and further includes the name of the file / directory entity to be registered. . The name of the file / directory entity registered as described above is output because the user does not specify the name of the file / directory entity when specifying the file / directory to be registered according to the classification name specification method. This is for the convenience of the person.

By using the classification name registration function as described above, the user can add a classification name to the classification items 1 to N in relation to the substance of the file / directory, and the classification name already added Can be changed. Here, in the present embodiment, two types of designation methods, a direct designation method and a classification name designation method, are prepared for the designation method of the file and directory to be registered. By properly using, the registration work of the classification name can be performed efficiently.

For example, when a certain file (same for a directory) is created with a file name of “XXX” and the classification names of classification items 1 to N are registered for the file, the direct designation method is suitable. Registration can be performed by inputting a registration command specifying the name “XXX” and the classification name to be registered in each of the classification items 1 to N from the input device 1. Similarly, when the name of the file or directory entity to be registered is known or can be specified by a wild card, the direct specification method is suitable. On the other hand, if a certain classification item i is “Y
In the case where the classification name of a certain classification item j (including the same case as i) is collectively changed to “ZZZ” for all the files and directories having the classification name of “YY”, the classification name The designation method is suitable, and a batch change can be performed by inputting a registration instruction specifying the classification item i, the registration target classification item j, and “ZZZ” from the input device 1.

(2) Class Name Reference The class name reference refers to confirming the classification names of the classification items 1 to N of the logical classification name group linked to the file / directory entity via the file descriptor. means.

When referring to the classification name, the user uses the keyboard 1-1 or the pointing device 1-2 of the input device 1 to specify the file or directory whose classification name is to be referred to, Specify which classification item of N you want to refer to. At this time, there are two types of specifying methods of a file and a directory to be referred to, such as a direct specification method and a classification name specification method, as in the case of registering a classification name. As a method of designating a classification item to be referred to, there are a method of designating individual classification items and a method of designating all classification items collectively.

The designation of the file / directory to be referred to and the designation of the classification item to be referred to (hereinafter referred to as a reference command) input from the input device 1 are performed by the classification name processing means 2
Passed to After checking the validity of the context of the passed reference instruction, the classification name processing means 2 executes the reference processing according to the flow shown in FIG.

First, the classification name processing means 2 determines whether the specification method of the file and directory to be referred to is the direct specification method or the classification name specification method (S11), and performs the following processing according to each specification method. Execute.

In the case of the direct designation method When the file / directory to be referred to is designated by the direct designation method, first, the classification name extracting means 2-1 uses
The file descriptor of the file / directory specified by the direct specification method is referred to by the file access procedure in the conventional file management method (S12).
The classification name extracting means 2-1 further refers to the corresponding logical classification name group from the storage position of the logical classification name group in the file descriptor, and extracts the classification name of the reference target classification item specified by the reference instruction. It is extracted (S13). And
The classification name extracting means 1-2 displays the reference result on the display 5-1 (S14). The reference result displayed at this time displays the classification name extracted in step S13.

Classification Name Designation Method When a file / directory to be referred to is designated by the classification name designation method, the classification name extraction means 2-1 directly sends the classification name storage unit 3 without passing through a file descriptor. To search for a logical category name group that matches the extraction condition specified by the reference instruction, and, in the searched logical category name group, the classification name of the reference target category specified by the reference instruction Is extracted (S15). Next, the classification name extracting means 2-1 traces the address to the file descriptor to which the logical classification name group referring to the classification name is assigned, and thereby the file / directory entity to which the logical classification name group depends. A name is obtained (S16). Then, the classification name extracting means 2-1 displays the reference result on the display 5-1 (S17). The reference results displayed at this time include:
Classification name extracted in step S13 and step S16
Contains the name of the file / directory entity that was referred to and was extracted in step. The reason for outputting the name of the file / directory entity is for the convenience of the user because the user does not specify the name of the file / directory entity when specifying the reference target file / directory in the classification name specification method. .

By using the classification name reference function as described above, the user can confirm the classification names of the classification items 1 to N related to the substance of the file / directory. Here, in the present embodiment, two types of designation methods, ie, a direct designation method and a classification name designation method, are prepared as a designation method of a file and a directory to be referred to. By using properly,
The work of confirming the classification name can be performed efficiently.

For example, if the original use of the file (same for a directory) cannot be estimated from the file name alone, a direct designation method is suitable for confirming the intended use.
By inputting from the input device 1 a reference command specifying a file name and, for example, collective reference of all classification items, the use of the file can be confirmed. Similarly, when the name of the file or directory entity to be registered can be specified by a wild card, the direct specification method is suitable. On the other hand, when the classification name of a certain classification item j (including the same case as i) is collectively confirmed for all the files and directories in which a certain classification item i has a classification name of “YYY” The designation of the classification name is suitable, and by inputting a reference instruction specifying the classification item i and the reference target classification item j from the input device 1, it is possible to confirm them collectively. Further, as described above, in the classification name designation method, the name of the corresponding file / directory entity is returned as a reference result, so that all files and directories in which a certain classification item i is a classification name of “ZZZ” are deleted. In the case of deletion, the names of all files / directories to be deleted can be obtained by inputting from the input device 1 a reference instruction in which both the classification term in the extraction condition and the reference target classification term are i.

FIG. 4 is a block diagram showing an embodiment of the present invention.
This embodiment includes a computer 6, an external storage device 8, an input device 1, a display device 5, and a recording medium 7 connected to the computer 6. The external storage device 8 is composed of a magnetic disk device or the like, and stores the file / directory entities (A, B,..., M) described in FIG. 1, the classification name storage unit 3, and the file descriptor 4. The computer 6 includes an existing file management unit 9 that manages files and directories in a tree-like directory structure, the classification name processing unit 2 described with reference to FIG. 1, a logical classification name group initial generation unit 10, and a file transfer unit. 11 is provided.

The recording medium 7 is a machine-readable recording medium such as a CD-ROM, a semiconductor memory, a magnetic disk device, and the like.
By controlling the operation of the computer 6, a file management unit 9, a classification name processing unit 2, a logical classification name group initial generation unit 10, and a file transfer unit 11 are realized on the computer 6.

When the file management unit 9 generates a new file / directory on the external storage device 8 according to a request from the user, the logical classification name group initial generation means 10 stores the new file / directory on the external storage device 8. In addition to generating an initial state logical classification name group for a file / directory, the logical classification name group and the file descriptor 4
This is a means for setting a link between. As a group of logical classification names in the initial state, the classification names of all the classification items are NULL.
May be used, but in that case, the user needs to register all the classification names. Therefore, in the present embodiment, attention is paid to the fact that a new file or directory is generally generated under a certain existing directory, and a group of logical classification names already assigned to the directory from which the file or directory is generated. Is inherited by newly generated files and directories, thereby reducing the burden on the user.

FIG. 5 is a flowchart showing a processing example of the logical classification name group initial generation means 10 in this case. When the file management unit 9 newly generates a file / directory, the logical classification name group initial generation unit 10 receives the address of the file descriptor of the newly generated file / directory and the file descriptor of the generation source directory. It is started by the file management unit 9. First, the logical classification name group initial generation means 10 secures an area for storing the newly generated logical classification name group for the file / directory in the classification name storage unit 3 of the external storage device 8 (S21). . Next, the group of logical classification names of the generation source directory is read from the classification name storage unit 3 via the file descriptor of the generation source directory, and copied to the secured area (S22). Next, a portion indicating the above area is added to the file descriptor of the newly generated file / directory (S
23) Change the address to the file descriptor in the area to the address to the file descriptor of the newly generated file / directory (S)
24).

FIG. 6 shows a logical classification name group initial generation means 10.
FIG. 9 illustrates how the logical grouping name group 603 of the file 602 inherits the contents of the logical grouping name group 604 of the directory 601 when the file 602 is generated under the directory 601. Therefore,
The user only needs to change the necessary classification name in the logical classification name group 603 of the file 602 by using the classification name registration function of the classification name processing means 2.

Referring back to FIG. 4, the file transfer means 11 is a means for transferring a file specified by the user through the input device 1 to a transfer destination specified by the user. The feature of this file transfer means 11 is that a file entity to be transferred is added with a logical classification name group of the file and transferred. For this reason, the classification name processing means 2 can also be used from the file transfer means 11.

FIG. 7 is a flowchart showing a processing example of the file transfer means 11. When a file transfer command is received from the user through the input device 1, the file transfer means 11
First, the transfer target file name specified by the file transfer command is transmitted to the file management unit 9 to read the file entity to be transferred (S31). Next, a reference command designating the transfer target file name and the batch reference of all the classification items is sent to the classification name processing means 2, and the logical classification name group related to the transfer target file is read (S32). Then, information on the classification names of all the classification items is added to the file entity, and the file entity is transferred to the transfer destination specified by the file transfer command (S3).
3). The transfer destination may be another computer connected via a communication line.
May be another external storage device (for example, a floppy disk device or the like) connected to the computer 6 on which is mounted.

By transferring the file entity with the logical classification name group added in this way, the transfer destination can use the file only by looking at the logical classification name group without checking the details of the file entity. Can be easily known.

[0053]

As described above, according to the present invention, the following effects can be obtained.

The use or semantic classification attributes of files and directories, which previously could only be implicitly held only in their own symbolized names, are explicitly labeled with multiple logical classifications. It can be managed as a name. Therefore, it is possible to provide a particularly effective means for classifying the use or semantics of the file / directory, particularly in the maintenance and management of the structure of the file and the directory.

According to the configuration that supports the classification name specification method as a file and directory specification method, all the files and directories having a predetermined classification name having a predetermined value are collectively referred to by the specified classification name. Becomes possible. In addition, the corresponding file /
Since the name of the directory entity is returned, it is possible to easily know the names of all files and directories for which the predetermined classification name has a predetermined value.

According to the configuration in which the initially generated logical classification names for newly generated files and directories are generated by copying the logical classification names associated with the source directory of the files and directories. In addition, it is possible to reduce the trouble of registering the logical classification name by the user himself.

According to the configuration in which, when a file entity is transferred, the logical category name group stored in the category name storage section is added in association with the file entity and transferred, the transfer destination does not check the details of the file entity. However, it is possible to easily know the purpose of the file or the like simply by looking at the group of logical classification names.
