BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for supporting a collaborative work between a plurality of users on a network, targeting a file shared by the plurality of users via the network.

[0002]

2. Description of the Related Art As a method of sharing a file on a network, a file to be shared is placed on a server by a client-server method so that a plurality of clients can access the file, or a network. There is a method in which files to be shared are placed on a plurality of terminals connected to each other, and when a file of a certain terminal is updated, the updated file is transferred to another terminal.

Further, as a system for supporting a collaborative work using a shared file, there is a system generally called a workflow management system. The workflow management system circulates the document information registered in the database and the files in the file management system among the users in a predetermined order, and the user who circulates the document information stores the document information. After the browsing, the operation of approving or rejecting the content of the document information is performed, and the file is corrected.

[0004]

However, the system which provides only the file sharing through the network has a function of setting a cooperative work processing path for supporting the cooperative work, an automatic change function of the access right, and a processing request message. In order to perform collaborative work, the user who updated the collaborative work target file sends the update request to the user who expects the next update, or expects the next update. It is necessary to set the access right to the collaborative work target file by itself so that only the user can read and write.

Further, there is no conventional workflow management system for supporting cooperative work using a shared file between groups. A system has also been proposed in which a file shared via a network is set as a work target and the access right of the shared file is automatically changed according to the work stage. , Once set as a collaborative work target of a workflow, access to the collaborative work target file is restricted. Therefore, a user other than the collaborative worker in the workflow sets the target file as a collaborative work target of the new workflow. Cannot be set.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to allow users existing in a distributed manner on a network to be similarly connected to a network in units of groups. Via the terminal
Any type of file can be shared via the network, and the shared files can be used as a collaborative work target for viewing, modifying, updating, etc., without time constraints imposed on individual users belonging to the group. When performing a collaborative work that can perform such processing, any shared file can be set as a collaborative work target file at any time, and a group such as a company or organization can be set as a collaborative work processing path. And a collaborative work support system, a collaborative work control method, a collaborative work control program, and the program, which can automatically change the access right that a group has to a collaborative work target file according to the progress of the collaborative work. It is to provide a recording medium.

FIG. 6 is a flowchart for explaining a processing algorithm when a read command or a write command is received, and FIG. 6 is a flowchart for explaining a processing algorithm when the cooperative work control unit receives a processing end notification.

As shown in FIG. 1, a collaborative work support system 10 using a shared file includes a plurality of user terminals 2.
1, 22, 23, 24 and 25 are communicably connected via a network 30. User terminals 21, 22,
Users A, B, C, D, who use 23, 24, 25
E shares files accumulated in the storage device in the cooperative work support system 10. The users A and B belong to the group F, the users C and D belong to the group G, and the user E belongs to the group H.

The collaborative work support system 10 includes a storage device 11 for storing files to be shared, and a file system controller 12 for controlling the files stored in the storage device 11.
An account database 13 that stores account information, an account management unit 14 that reads the account information, and an access right database 15 that stores access right information of files accumulated in the storage device 11.
And an access right management unit 16 for reading and writing access right information, a message transfer unit 17 for notifying individual users belonging to a group of a request for a cooperative work, and a set of arbitrary group accounts. A process database 18, which stores the process definition information as a unit of cooperative work, communicates with a user terminal, receives and interprets a command, and a file system controller 12, an account manager 14, an access right manager 16, A collaborative work control unit 19 for integrally controlling the collaborative work using the message transmission unit 17 and the process database 18 is provided.

In the present embodiment, the file system control unit 12, the account management unit 14, the access right management unit 1
6, the message transmission unit 17 and the cooperative work control unit 19,
An example implemented as a CGI program or a servlet will be described. Also, using HTTP as a communication protocol,
E-mail is used as a means for transmitting the processing request. In order to use electronic mail, a mail server 40 also needs to be connected to the network 30 as shown in FIG.

The file system control unit 12 provides a function of executing a read process, a write process, and a copy process for the shared files accumulated in the storage device 11. Further, although a plurality of shared files are stored in the storage device 11, the file system control unit 12 uses a file identifier capable of uniquely identifying each shared file.
Produces.

That is, when the file system control unit 12 receives a read command for an arbitrary file identifier from the cooperative work control unit 19, the file system control unit 12 reads the file corresponding to the file identifier stored in the storage device 11 and controls the cooperative work. When the file is passed to the unit 19 and there is a write command for an arbitrary file identifier, the file passed from the cooperative work control unit 19 is overwritten on the file corresponding to the file identifier stored in the storage device 11. Further, the file system control unit 12, when receiving a copy command for an arbitrary file identifier from the collaborative work control unit 19, creates a duplicate of the file and sends the file identifier corresponding to the duplicate file to the collaborative work control unit 19. To return.

The account management unit 14 stores the information of the user account having the user name and the message transmission identifier as attributes, the group account having the group name and one or more belonging user names as attributes, from the account database 13 Read information. User accounts are identified by user name and group accounts are identified by group name. That is, when there is a command to read the account information specifying the user name or the group name from the cooperative work control unit 19, the account management unit 14 reads the corresponding account information stored in the account database 13, and the cooperative work control unit Give to 19.

The access right management unit 16 reads or writes the access right information of the files accumulated in the storage device 11 from the access right database 15. As shown in FIG. 2, the access right information stored in the access right database 15 is stored as information represented by a file identifier, a group name, and a combination of a readable authority and a writable authority for a file.

The message transmission unit 17 uses the message transmission identifier of each user stored in the account database 13 as the attribute of the user account to transmit the processing request of the cooperative work to each user. In this embodiment, an electronic mail address is used as the message transmission identifier.

That is, when transmitting a processing request to an arbitrary user, the message transmission unit 17 inquires of the account management unit 14 about the account information of the user, acquires an electronic mail address which is a message transmission identifier,
The mail server 40 is instructed to send the processing request e-mail.

The process database 18 stores process definition information on a unit of cooperative work performed by a set of arbitrary group accounts as a process.

The process definition information is, as shown in FIG.
The process identifier used to uniquely identify the process, the user name of the user account that represents the originator who initializes the process (originator), and the file to uniquely identify the file to be processed by the process. It is composed of a file identifier (target shared file) generated from the system control unit 12, and a processing path and a status indicating the order of processing in the process.

The processing route is represented by a list of group names. A process end determination mode is set as an attribute for each group on the process route. That is, if the group on the processing route is set to the “AND mode”, the cooperative work control unit 19 must receive the notification of the processing end from all the users belonging to the group, and then the next on the processing route. The processing request is not transmitted to the individual users who belong to the set group.

If the group on the processing route is set to the "OR mode", if the cooperative work control unit 19 receives a processing end notification from any one of the users belonging to the group, the processing route The processing request is transmitted to the individual users who belong to the group set next to the above.

For each user who belongs to the group on the processing path, the processing status is "unprocessed",
"Processing" and "processed" are set as attributes. When the processing state of “unprocessed” is set for the account on the processing path, it indicates that the corresponding account has not been requested to process. The processing state "processing in progress" represents a state in which processing has already been requested for the corresponding account, and the cooperative work control unit 19 has not yet received a processing end notification from the corresponding account. The processing state of “processed” indicates that the cooperative work control unit 19
Indicates that the processing completion notification has already been received from the corresponding account.

Further, the process definition information includes initial access right information indicating access right to the target shared file of each group performing the collaborative work at the time of process definition, and target of each group performing the collaborative work at the time of processing request. The access right information at the time of processing request, which indicates the access right to the shared file, is set.

When the collaborative work control unit 19 receives a collaborative work start command from an arbitrary user as parameters, the identifier of the target file, the list of group names indicating the processing paths, and the processing end determination mode of each group are received as shown in FIG. As shown, the file system control unit 12 is instructed to make a copy of the collaborative work file that is the actual target of the collaborative work (51), and the file identifier of the duplicated file is obtained from the file system control unit 12. Then, an arbitrary process identifier is generated (52), process definition information is generated with the user who has sent the start command as the originator, and registered in the process database 18 (53). At the same time, the collaborative work control unit 19 notifies the individual users belonging to the group set at the top of the processing route of the process,
The message transmission unit 17 is instructed to transmit the processing request (54). Along with the instruction, the message transmission unit 17 notifies the user of the processing request, the e-mail address of the user,
URL to be accessed first by the requested user
Is passed as a parameter.

The message transfer unit 17 which has received the instruction to transfer the processing request receives the UR received as a parameter.
The mail server 40 is instructed to send the e-mail in which L is described in the text to the e-mail address of each user who similarly received it as a parameter.

Each of the user terminals 21 to 25 is equipped with a mailer, which is an application for reading electronic mail, and a web browser, which is an application for accessing CGI and servlets. Users A, B, C, D, E
Receives a processing request for cooperative work by e-mail. When the e-mail, which is the processing request received by the mailer, is opened, the URL to be accessed first is described. Therefore, the URL is used to cooperate with the cooperative work control unit 19 in the cooperative work support system 10 via the web browser. To access.

By this access, the user reads or writes the target file accumulated in the storage device 11 in the cooperative work support system 10 through the page displayed on the web browser. Therefore, the user who receives the processing request reads the target file through the web browser, browses it, performs processing such as making corrections on the target file, and then writes the target file in the storage device 11 through the web browser. be able to.

When the user who receives the processing request reads or writes the target file, the collaborative work control unit 19 that receives the read command or the write command first causes the access right management unit 16 to perform the operation, as shown in FIG. On the other hand, an inquiry is made to determine whether the user has the readable or writable authority for the target file (61). At this time, if the user has the read permission or the write permission, a read command or a write command is sent to the file system controller 12 (62, 63). On the other hand, if the user does not have the readable authority or the writable authority, the message transmission unit 17 is instructed to notify the user who has sent the command that the processing is impossible because the user does not have the authority (6
2, 64).

The user who finally finished the process transmits a process end notification to the cooperative work control unit 19 in the cooperative work support system 10 via the page using the corresponding process identifier as a parameter.

Upon receiving the processing end notification from the user, the cooperative work control section 19 performs the processing according to the flowchart of FIG.

That is, the process definition information corresponding to the process identifier sent at the same time as the processing end notification is acquired from the process database 18 (71), and the processing state of the user who sent the processing end notification is set to "processed". Set (72). Then, the processing end determination mode of the group to which the user belongs is checked (73).

When the processing end determination mode is the "AND mode", it is determined whether the processing states of all the users in the group are "processed" (74). If all are not “processed”, the process returns to the process end notification waiting state, and if all are “processed”, a process 75 for determining whether or not the next group is set on the processing route. Transition to. In addition, the processing end determination mode is "O.
In the case of the “R mode”, the process unconditionally transits to the process 75.

In the process 75, if the next group is not set on the process path, a notice that all processes have been completed is sent to the originator of the process (76). Also,
If the following groups are set on the processing route,
The message transmission identifier of each user belonging to the corresponding group is acquired from the account management unit 14, and the processing request is sent to the next account on the processing path.
The message transfer unit 17 is instructed using the message transfer identifier as a parameter (77). Further, the access right management unit 16 is instructed to change the access right that the next group on the processing path has in the target shared file of the process according to the access right information at the time of the processing request in the process definition information. (78), the process returns to the processing completion notification waiting state.

When the user defines an arbitrary process for performing the collaborative work, the user accesses the collaborative work control section 19 as a drafter via the web browser installed on the user terminal. . Through the cooperative work control unit 19, the user who is the drafter acquires the file identifier of the file that is the target of the cooperative work, which is necessary for the process information definition, from the file system control unit 12, and creates the processing path. The account information necessary for the process is acquired from the account management unit 14, and further, the initial access right information for setting the access right of the target shared file at the time of the process definition and each group set on the processing path receives the processing request. Set the access right information at the time of processing request for setting the access right of the target shared file at that time.

Furthermore, the following embodiment is also conceivable.

That is, the user who belongs to the group that receives the request for the cooperative work submits the requested processing to the subgroup in the group as a new cooperative work.
This is a form of nesting a cooperative work processing path. In Figure 7,
The conceptual diagram of nesting of this cooperative work processing path is shown.

In FIG. 7, users J, K and L belong to the group U (81), and users M and L belong to the group V (82).
N, O, P, Q, and R belong, and users S and T belong to the group W (83). In addition, users N, O, P
Belongs to the subgroup X (84), and the users Q and R belong to the subgroup Y (85). Here, the sub-group X and the sub-group Y are simply called sub-groups for convenience, and are conceptually the same as the groups held in the account database 13.

In FIG. 7, user I is the originator,
The cooperative work process 86 among the groups U, V, W is defined through the cooperative work control unit 19. When the processing in the group U is completed in the cooperative work process 86, the processing request notification is transmitted to all the users belonging to the group V. At this time, the user M selects the cooperative work process 86.
The shared work subprocess 87 between the subgroups X and Y for the shared file that is the target of
If the definition is made through the cooperative work control unit 19, the cooperative work processing paths can be nested. Here, the cooperative work sub-process 87 is simply called a sub-process for convenience, and is conceptually the same as the cooperative work process held in the process database 18.

When the work in the cooperative work sub-process 87 is completed, the processing completion notice is transmitted to the user M.

The user M regards the end of the work of the cooperative work subprocess 87 as the end of the processing of the group V in the processing path of the cooperative work process 86, and informs the cooperative work control unit 19 that the processing of the group V is completed. When notified, the processing request for the cooperative work process 86 is transmitted to the group W that is the next processing request target on the path of the cooperative work process 86.

In the case of the embodiment of nesting the collaborative work processing path described with reference to FIG. 7, what process is actually performed internally by the group V, which has requested the collaborative work, for the user I who is the drafter. You don't need to know about. Therefore, from the viewpoint of the user I, the processing content in the group V is black-boxed.

Further, in the above description, it is described that the user M makes a bill for the cooperative work sub-process 87 in FIG. 7, but it is also possible to automate the bill.

That is, the e-mail requesting processing to group V in the collaborative work process 86 is automatically filtered, and when the e-mail is received, the collaborative work sub-process 87 is automatically sent to the collaborative work control section 19. An application that issues a ticket to the user terminal (2
1-25) and the mail server 40, the cooperative work process 86 and the cooperative work sub-process 87 can be automatically linked.

Although the embodiment of the present invention has been described above, the present invention is not limited to this. For example, the collaborative work support system 10 is implemented using CGI or a servlet, and the user communicates with the collaborative work support system 10 via HTTP using a web browser. It is not necessary to perform HTTP-based communication such as a servlet, and a client application that can understand the protocol may be installed in the user terminal by using a unique protocol that communicates with the cooperative work support system 10. Further, although the electronic mail is used as the means for transmitting the processing request message, it is also possible to use other communication means such as SOAP.

[0075]

As described in detail above, according to the present invention,
When multiple users who use files shared on the network support collaborative work between groups, such as browsing, modifying, and updating the shared files in order, The effect can be obtained. -A group can be set as a collaborative work processing route so that collaborative work between groups such as companies and organizations can be performed. The co-worker process drafter does not need to worry about what kind of processing is to be performed in a group when entrusting the processing of a task to an arbitrary group. -As a file to be subjected to the actual collaborative work process when the collaborative work is submitted so that users who are not involved in the collaborative work can also access the shared file during the collaborative work,
A duplicate of the collaborative work target file is automatically generated. -In order to prevent other collaborators from accidentally modifying the collaborative work target file, the access right of the collaborative work target shared file is automatically changed according to the progress of the collaborative work. -In order to perform collaborative work efficiently, a processing request message is automatically transmitted to individual users who belong to a group that is a collaborative work member when the processing order comes. -By nesting cooperative work processing paths, it is possible to handle complicated processing paths.
