Description

  The present invention relates to a data structure of a document file, a recording medium, a document file transfer method, a document file reception program, a document file reception method, and an information processing apparatus, and more particularly to a document file suitable for transferring various files handled by the information processing apparatus. The present invention relates to a data structure, a recording medium, a document file transfer method, a document file reception program, a document file reception method, and an information processing apparatus.

  In recent years, various types of electronic documents (digital documents) that can be browsed using an information processing apparatus have become widespread. Electronic document formats include text, PDF, HTML, XML, and the like. When exchanging or sharing information using such an electronic document, the electronic document is transferred to a server or a partner PC that exchanges or shares information using some kind of transfer method. As a method of transferring an electronic document, transmission as an attached file of an electronic mail, copying to a shared folder, transmission with a communication tool, and the like are common.

  Normally, electronic documents cannot be browsed or edited by themselves, and require an application for browsing and editing. In other words, if there is no application for browsing or editing an electronic document in the transfer destination server or PC, the contents of the electronic document cannot be browsed or edited. For this reason, a user who intends to transfer an electronic document must transmit the electronic document on the premise that there is an application for browsing, editing, etc. of the electronic document to be transferred.

  In addition, when using the transfer method of copying an electronic document to a shared folder or the transfer method of transmitting an electronic document as an attached file of an e-mail, the transferred electronic document is used by whom (where information processing device) It is difficult to know what has been done. When managing electronic documents using groupware or the like, there is no problem as long as the electronic document is registered as an electronic document used only by groupware. However, electronic documents are copied and used in various places, and management information such as usage history of electronic documents that are not under the management of groupware cannot be handled.

  As described above, the current electronic document is in a state of being separated from an application for browsing and editing and information related to the electronic document. In other words, the electronic document is in a state in which the electronic document is in a state of being deviated from the viewing, editing, and management of the electronic document. Furthermore, since some types of electronic documents are composed of a plurality of contents including a document file and multimedia files such as images and moving images attached to the document file, handling is complicated for the user.

In order to solve the above-mentioned problems in handling an electronic document, content that is an expression entity on the electronic document, an application for viewing and editing the electronic document, information about the electronic document, Is an encapsulated document that can be handled as a single document file (see, for example, Patent Documents 1-6).

  A common action performed by a user in a method of transferring an electronic document is an operation of searching for an electronic document to be transferred. When an electronic document is transmitted as an email attachment, the electronic document to be transferred must be found and selected as an attachment. When copying an electronic document to a shared folder, the electronic document to be transferred must be found and copied to the shared folder. When transferring an electronic document using a communication tool, the electronic document to be transferred must be searched and selected as a transfer file. Even in the above-described encapsulated document, the operation of searching for an encapsulated document to be transferred is not different from the operation of searching for an electronic document to be transferred.

  The act of searching for an electronic document is a very complicated task for the user. For example, it often takes a long time to search for an electronic document to be transferred, or it takes time to search for an electronic document that was not expected. Even if the location of an electronic document is clearly known, if the hierarchy of the folder or directory in which the electronic document is stored is deep, moving to the folder or directory in that hierarchy and selecting the electronic document is not This is a stressful action for the user.

  In addition, the user activates an electronic document by an application, and performs browsing, editing, and the like on the electronic document. For example, if it becomes necessary to copy an electronic document currently being browsed to a shared folder, the user closes the electronic document currently being browsed, locates the electronic document, copies the electronic document, and opens or specifies the shared folder. , You are forced to paste the copied electronic document. Such an operation is very troublesome for the user, and the thought can be stopped by closing the electronic document currently being browsed, which is not a desirable action from the viewpoint of intellectual production efficiency.

  Furthermore, the user also has the opportunity to transfer an electronic document in some workflow. For example, in the process of review approval, the electronic document is transferred from the creator of the electronic document to the reviewer or from the reviewer to the approver. Actually, the creator registers the electronic document in a server, groupware, or the like, and only the link to the location where the electronic document is registered is notified to the examiner and the approver. That is, the electronic document is not actually transferred. Even in such a case, the user needs to perform an operation of registering the electronic document, so that troubles such as searching for the electronic document occur.

A transfer program 134 that is a program and a basic program 135 that is a program that is called when the encapsulated document 100 is activated are included. In the following description, an example of the program group 130 in FIG. 2A will be described.

  The structure file 110 is a display information file in which the structure (configuration) of the digital information file and the display state on the electronic document are specified. In the structure file 110 of FIG. 2A, the structure of the electronic document, the program to be used, the correspondence between the contents and the program, and the URI (Uniform Resource Indentifiers) of the storage location of the contents and programs are described in XML as shown in FIG. 3, for example. ing.

  FIG. 3 is a configuration diagram of an example of a structure file described in XML. The structure file 110 corresponds to a part 111 in which a URI that is a content storage location is described, a part 112 in which a URI that is a program storage location is described, a structure of an electronic document, a program to be used, a content, and a program. It is comprised with the part 113 in which the relationship was described.

  The structure file 110, the content 120, and the program group 130 that constitute the encapsulated document 100 are stored in one file called an archive file. Thereby, the structure file 110, the content 120, and the program group 130 are encapsulated as one electronic document. Examples of the file format of such an archive file include a ZIP format and an LHA format. By using an archiver program having a storage function and a decompression function, the archive file can handle the structure file 110, the content 120, and the program group 130 as one archive file.

  Next, processing for starting the encapsulated document 100 as shown in FIGS. 2A and 3 using the information processing apparatus 1 will be described. FIG. 4 is a flowchart of an example of processing for starting an encapsulated document. When the user gives an instruction to activate the encapsulated document 100, the OS activates the basic program 135 stored in the archive format as an archive file in the encapsulated document 100. The process of the flowchart of FIG. 4 is started after the basic program 135 is started.

  In step S10, the basic program 135 creates a display window for displaying an electronic document. In step S11, the basic program 135 reads the structure file 110 in the encapsulated document 100. In step S12, the basic program 135 analyzes the tag structure of the read structure file 110.

  In step S13, the basic program 135 starts one program of the program group 130 corresponding to the tag name (hereinafter referred to as an extension program) in another thread based on the analysis result in step S12, and attributes corresponding to the extension program. If there is, supply the attribute to the extension program.

  In step S14, the basic program 135 determines whether all the processes for analyzing the tag structure of the structure file 110 have been completed. If it is determined that the process of analyzing the tag structure of structure file 110 has not yet been completed (NO in S14), basic program 135 returns to the process of step S12. Through the processing in steps S12 to S14, the basic program 135 activates the document viewer 131, the image viewer 132, the moving image viewer 133, and the transfer program 134, which are extended programs, in different threads.

  If it is determined that the process of analyzing the tag structure of the structure file 110 has been completed (YES in S14), the extension program started in step S13 proceeds to step S15 and analyzes the attributes supplied from the basic program 135. Proceeding to step S16, the extension program reads the necessary content 120 from the encapsulated document 100 based on the result analyzed at step S15.

  In step S17, the extension program displays the content 120 in an area corresponding to the attribute in the display window created in step S10. Further, an extension program that executes a specific function without referring to the content 120 may display a button for causing the user to execute a predetermined function. Through the processing of steps S10 to S17, the encapsulated document 100 can display the contents of the document file 121, the image file 122, and the moving image file 123 on the display window secured by the basic program 135 using the information processing apparatus 1.

  In step S18, the extension program determines whether or not various events have been detected. If the occurrence of an event is not detected (NO in S18), the extension program repeats the process of step S18. If the occurrence of an event is detected (YES in S18), the extension program proceeds to step S19 and executes an operation corresponding to the event. After executing the operation according to the event in step S19, the extension program returns to step S18.

  For example, when the encapsulated document 100 as shown in FIGS. 2A and 3 is activated, the information processing apparatus 1 displays an electronic document browsing screen as shown in FIG. FIG. 5 is an image diagram of an example of an electronic document browsing screen. 5 includes an area 201 for displaying the contents of the document file 121, an area 202 for displaying the contents of the image file 122, an area 203 for displaying the contents of the moving image file 123, and a transfer program 134.

The transfer program 134 receives and registers the user name and IP address of the information processing apparatus 1b transmitted from the directory server 20.

  When the document file receiving program 400 cannot receive the encapsulated document 100, the document file receiving program 400 notifies the directory server 20 to that effect. The directory server 20 deletes the transfer destination information of the transfer destination that is received from the transfer destination document file reception program 400.

  Next, processing performed by the transfer program 134 and the document file reception program 400 when the document transfer button 204 on the electronic document browsing screen 200 is clicked with the mouse 11 will be described.

  FIG. 13 is a flowchart of an example of processing performed by the transfer program. FIG. 14 is a flowchart of an example of processing performed by the document file reception program. When the document transfer button 204 on the electronic document browsing screen 200 is clicked with the mouse 11, the transfer program 134 proceeds to step S31 in FIG. 13 and detects the occurrence of a click event of the document transfer button 204.

  The transfer program 134 displays a transfer destination list screen 300 as shown in FIG. 6 on the display 9 to allow the user to select a transfer destination. When the transfer destination is selected, the transfer program 134 proceeds to step S32 and creates authentication information. As the authentication information, for example, a digest value of a predetermined file encrypted with a secret key, a password, or the like is used. The transfer program 134 transmits the created authentication information to the transfer destination document file reception program 400.

  In step S41 of FIG. 14, the document file reception program 400 receives authentication information from the transfer program 134 of the transfer source. In step S42, the document file receiving program 400 performs authentication by checking the received authentication information. In step S43, the document file reception program 400 transmits the authentication result in step S42 to the transfer program 134 of the transmission source.

  In step S33 of FIG. 13, the transfer program 134 receives the authentication result from the transfer destination document file reception program 400. Proceeding to step S34, if the authentication result is OK (YES in S34), the transfer program 134 proceeds to step S35. In step S <b> 35, the transfer program 134 transfers the encapsulated document 100 to the transfer destination document file reception program 400 and ends the process. On the other hand, if the authentication result is not OK (NO in S34), the transfer program 134 ends the process without transferring the encapsulated document 100 to the transfer destination document file receiving program 400.

  In step S44 of FIG. 14, the document file reception program 400 receives the encapsulated document 100 from the transfer program 134 of the transfer source. In step S45, the document file receiving program 400 proceeds to step S46 if the received encapsulated document 100 has been authenticated (YES in S45). In step S46, the document file reception program 400 activates the received encapsulated document 100 and ends the process. On the other hand, if the received encapsulated document 100 has not been authenticated (NO in S45), the document file receiving program 400 ends the process without activating the encapsulated document 100.

  FIG. 15 is a configuration diagram of another example of the transfer program. The transfer program 134 in FIG. 15 is the same as the transfer program 134 in FIG. 9 except for the authentication information processing function 604, and the same parts are denoted by the same reference numerals and description thereof is omitted. The authentication information processing function 604 creates authentication information and transmits it to the transfer destination document file reception program 400. Also, the authentication information processing function 604 determines whether or not to transfer the encapsulated document 100 according to the authentication result received from the transfer destination document file reception program 400. For example, the authentication information processing function 604 performs the processing in steps S32, S33, and S34 in FIG.

  FIG. 16 is a configuration diagram of another example of the document file receiving program. The document file reception program 400 in FIG. 16 is the same as the document file reception program 400 in FIG. 10 except for the authentication function 703, the approval notification function 704, and the document activation function 705. Is omitted.

  The authentication function 703 performs authentication by checking the authentication information received from the transfer program 134 of the transfer source. The approval notification function 704 transmits the authentication result performed by the authentication function 703 to the transfer program 134 of the transfer source. The document activation function 705 determines whether to activate the encapsulated document 100 according to whether the encapsulated document 100 received from the transfer program 134 of the transfer source has been authenticated.

  For example, the authentication function 703 performs the processing of steps S41 and S42 in FIG. The approval notification function 704 performs the processing in step S43. Further, the document activation function 705 performs the processes in steps S44 to S46.

  13 and FIG. 14, the received information processing apparatus 1b can activate the received encapsulated document 100. Further, by performing authentication before transferring the encapsulated document 100, the transfer destination information processing apparatus 1b can prevent the unauthorized encapsulated document 100 that has not been authenticated from being activated.

  Further, since it is not known how the encapsulated document 100 is copied after it is transferred, an access right may be set before the transfer. For example, the access right for the encapsulated document 100 is set by adding the transfer destination user ID to the access control list in the encapsulated document 100. The encapsulated document 100 to which the access right is set can be activated only by a user whose user ID is included in the access control list in the encapsulated document 100. By setting an access right to the encapsulated document 100, it is possible to prevent browsing or editing even if the encapsulated document 100 is illegally copied.

  In step S35, the transfer program 134 transfers the encapsulated document 100 to the transfer destination document file reception program 400, and the processing ends. However, the transferred encapsulated document 100 may be deleted. FIG. 17 is a configuration diagram of another example of the transfer program. The transfer program 134 in FIG. 17 is the same as the transfer program 134 in FIG. 9 except for the document erasing function.

  The document erasing function 605 automatically erases the transferred encapsulated document 100. For example, when the encapsulated document 100 is an examination approval document, the same encapsulation can be performed by automatically erasing the transferred encapsulated document 100 or automatically erasing when the user closes the encapsulated document 100. It is possible to prevent the document 100 from being scattered.

  Further, by encapsulating a text file in which information such as a transfer source (sender), transmission date / time, transfer destination (recipient), and reception date / time is recorded in the encapsulated document 100, the transfer history of the encapsulated document 100 is recorded. Can be left as a management record. Furthermore, it is possible to determine whether or not the encapsulated document 100 is an original by encapsulating a text file in which information such as a copy is recorded.

  In the first embodiment, the example in which the encapsulated document 100 itself is transferred has been described. However, the content 120 in the encapsulated document 100 can be selected and transferred. However, when only the content 120 is transferred, there may be no program corresponding to the content 120 at the transfer destination. Therefore, an example will be described in which the selected content 120 and a program corresponding to the content 120 are encapsulated and transferred. In this case, the information processing apparatus 1a as the transfer source displays a content selection screen as shown in FIG. FIG. 18 is an image diagram of an example of a content selection screen.

  18 includes an area 801 for displaying the contents of the document file 121, an area 802 for displaying the contents of the image file 122, an area 803 for displaying the contents of the moving image file 123, and an OK button 804. Including. When the area 801 to 803 is clicked with the mouse 11, the document file 121, the image file 122, and the moving image file 123 are selected as the content 120 corresponding to the area 801 to 803.

  In the content selection screen 800 of FIG. 18, areas 801 and 802 are clicked with the mouse 11, and the document file 121 and the image file 122 are selected as the contents 120 corresponding to the areas 801 and 802. When the user clicks the OK button 804, the transfer program 134 performs processing as shown in FIG.

  FIG. 19 is a flowchart of another example of processing performed by the transfer program. In step S51, the transfer program 134 acquires the content 120 selected by the user on the content selection screen 800. In addition, the transfer program 134 selects and acquires a program corresponding to the acquired content 120 from the contents described in the structure file 110. In the content selection screen 800 of FIG. 18, a document file 121, an image file 122, a document viewer 131, and an image viewer 132 are acquired.

  In step S52, the transfer program 134 generates the structure file 110 for the newly created encapsulated document 100. The structure file 110 generated here may be obtained by extracting necessary contents from the structure file 110 of FIG. Note that the layout of the structure file 110 is reset.

  In step S53, the transfer program 134 encapsulates the content 120 acquired in step S51 and the program corresponding to the content and the structure file 110 generated in step S52 to generate the encapsulated document 100. In the content selection screen 800 of FIG. 18, the encapsulated document 100 is formed by encapsulating the structure file 110, the content 120 including the document file 121 and the image file 122, and the program group 130 including the document viewer 131 and the image viewer 132. Generated. In step S54, the transfer program 134 transfers the encapsulated document 100 generated in step S53 to the transfer destination document file reception program 400, and ends the process.

  FIG. 20 is a configuration diagram of another example of the transfer program. The transfer program 134 in FIG. 20 is the same as the transfer program 134 in FIG. 9 except for the content selection function 606 and the encapsulation function 607.

  The content selection function 606 acquires the content 120 selected on the content selection screen 800 from the encapsulated document 100, acquires the program corresponding to the acquired content 120 from the encapsulated document 100, and generates the structure file 110. The encapsulation function 607 encapsulates the acquired content 120, the program corresponding to the content 120, and the generated structure file 110 to generate the encapsulated document 100. For example, the content selection function 606 performs the processing of steps S51 and S52 in FIG. The encapsulation function 607 performs the processing in step S53.

  With the processing in FIG. 19, the information processing apparatus 1b that is the transfer destination can reliably start the content 120 and perform browsing, editing, and the like. In the process of FIG. 19, the program corresponding to the selected content 120 is also bundled with the encapsulated document 100, but the program need not necessarily be bundled.

  In the first and second embodiments, the example in which the transfer function is added to the encapsulated document 100 has been described. However, a communication function can be further added. Here, the data structure of the encapsulated document 100 with the communication function added will be described. 21A and 21B are data structure diagrams of another example of the encapsulated document. The encapsulated document 100 in FIGS. 21A and 21B is the same as the encapsulated document 100 in FIGS. 2A and 2B except for the contents of the structure file 110 and the communication program 136. Description is omitted.

  The communication program 136 is included in the program group 130. For example, the communication program 136 is a program for exchanging information using TCP / IP, and realizes point-to-point (hereinafter referred to as P2P) communication.

  The structure file 110 is configured as shown in FIG. FIG. 22 is a configuration diagram of another example of a structure file described in XML. The structure file 110 in FIG. 22 is the same as the structure file 110 in FIG. 3 except for a part thereof.

  The structure file 110 in FIG. 22 includes a portion 114 in which a URI that is a storage location of a program is described, and a portion 114 in which a URI that is a storage location of the communication program 136 is described, and the structure and use of an electronic document. 3 is different from the structure file 110 in FIG. 3 in that the portion 113 in which the correspondence relationship between the program and contents and the program is described includes the portion 115 in which the communication program 136 is described as the program to be used.

  When P2P communication is realized using the encapsulated document 100 in FIG. 21A, the same encapsulated document 100 is activated by the communication source information processing apparatus 1a and the communication destination information processing apparatus 1b as shown in FIG. It is necessary to keep. FIG. 23 is a configuration diagram of an example of a system that performs communication using an encapsulated document. The encapsulated document 100 activated by the information processing apparatus 1a and the encapsulated document 100 activated by the information processing apparatus 1b can communicate with each other by synchronizing their states while transmitting and receiving information.

  When information is transmitted and received between the encapsulated documents 100, it is necessary to hold the same encapsulated document 100 between the communication source information processing apparatus 1a and the communication destination information processing apparatus 1b. That is, when it is desired to communicate with one or a plurality of other users using an encapsulated document 100 that a certain user has, the same encapsulated document 100 must be distributed by some method.

  As a method for distributing the encapsulated document 100, it is conceivable that the encapsulated document 100 is downloaded on a Web server with access rights, or recorded on a removable medium such as a CD-R and sent. Further, by using the transfer function of the encapsulated document 100 described above, the encapsulated document can be distributed easily and quickly.

  Also, when realizing P2P communication using the encapsulated document 100, it is always a problem how to find the encapsulated document 100 of the communication destination. A user who operates the communication source information processing apparatus 1a may not know the IP address of the communication destination information processing apparatus 1b. Even if the user who operates the information processing apparatus 1a as the communication source knows the IP address of the information processing apparatus 1b as the communication destination, the encapsulated document 100 may be activated by a device other than the information processing apparatus 1b.

  Therefore, the encapsulated document 100 has a function of automatically setting its own network environment (for example, an IP address) before being transferred. For example, when transferred from the information processing apparatus 1a, the encapsulated document 100 sets the IP address of the information processing apparatus 1a as a network environment. In this case, the information processing apparatus 1b of the communication destination can communicate with the encapsulated document 100 of the information processing apparatus 1a by simply starting the encapsulated document 100.

  The process of automatically setting its own network environment is easy to activate the encapsulated document 100 and cause the internal program to acquire a network environment such as an IP address. Then, the network environment such as the acquired IP address and port number is set in the structure file 110 as shown in FIG. 24, for example.

  FIG. 24 is a configuration diagram of another example of a structure file described in XML. The structure file 110 in FIG. 24 is the same as the structure file 110 in FIG. 22 except for a part thereof.

  The structure file 110 in FIG. 24 includes a portion 113 in which the structure of an electronic document, a program to be used, and a correspondence relationship between contents and programs are described, and a portion 116 in which a communication program 136 and a network environment are described as programs to be used. It is different from the structure file 110 of FIG. 22 in that it is included. In the structure file 110 of FIG. 24, an IP address and a port number are set in the portion 116 as a network environment. When the directory server 20 is used, the directory server 20 may inquire about the network environment.

  FIG. 25 is a flowchart of an example of processing up to establishment of communication between a communication source information processing apparatus and a communication destination information processing apparatus. In step S60, the information processing apparatus 1a as the communication source activates the encapsulated document 100 as shown in FIG. 21A. In step S61, the information processing apparatus 1b that is the communication destination starts the document file reception program 400. Note that either of the processes in steps S60 and S61 may be performed first.

  In step S62, the encapsulated document 100 activated by the information processing apparatus 1a sets its network environment in the structure file 110 as shown in FIG. Then, the information processing apparatus 1a displays an electronic document browsing screen as shown in FIG. FIG. 26 is an image diagram of an example of an electronic document browsing screen.

  26 includes an area 901 for displaying the contents of the document file 121, an area 902 for displaying the contents of the image file 122, an area 903 for displaying the contents of the moving image file 123, and a communication program 136. A created communication button 904 and a document transfer button 905 created by the transfer program 134 are included.

  When the document transfer button 905 is clicked with the mouse 11, the transfer program 134 proceeds to step S63, and transfers the encapsulated document 100 as shown in FIG. 21A to the communication destination document file reception program 400.

  In step S64, the document file reception program 400 receives the encapsulated document 100 from the transfer program 134 of the communication source. In step S65, the document file reception program 400 activates the received encapsulated document 100. The information processing apparatus 1b displays an electronic document browsing screen 900 as shown in FIG.

  When the communication button 904 is clicked with the mouse 11, the communication program 136 of the encapsulated document 100 activated by the information processing apparatus 1b proceeds to step S66, and the network environment of the information processing apparatus 1a described in the structure file 110 is reached. And establish communication with the encapsulated document 100 activated by the information processing apparatus 1a.

  When the sender transfers the encapsulated document 100 to a plurality of recipients, radial communication is established with the recipient as a base point as shown in FIG. That is, communication between each recipient is not established. Therefore, after the radial communication between the sender and the receiver is established as shown in FIG. 27, the network environment of the one receiver is notified to the other receivers so that the communication between the receivers can be achieved. It establishes like 28.

  In the second embodiment, the example in which the content 120 in the encapsulated document 100 and the program corresponding to the content 120 are encapsulated and transferred has been described. However, if the communication program 136 is encapsulated and transferred together, the capsule 120 Communication can be achieved using the document 100. In this case, it is desirable to incorporate in the content selection function 606 a function that allows the user to select a program to be encapsulated.

  By using the encapsulated document 100 as shown in FIG. 21A, the encapsulated documents 100 can communicate with each other, and communication can be achieved using the encapsulated document 100.
