Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus for assuring editing reliability of a non-supported editing command from a remote location, and an operation method thereof. [0002]

The present invention relates to a technique for ensuring the editing reliability of a web document by dividing the editing command inputted from another user into a supporting editing command and a non-supporting editing command.

2. Description of the Related Art [0002] Recently, various electronic document-related programs have been released to enable electronic documents to be viewed, created, and edited using electronic terminal devices such as computers, smart phones, tablet PCs, and the like.

Examples of such electronic document related programs include a word processor for basic document creation and editing, a data input, an arithmetic operation, a spreadsheet for supporting data management, and presentation programs for assisting presenters.

Conventionally, in order to view, create and edit an electronic document by using an electronic terminal device, a user has to install the above-mentioned electronic document related programs directly in the electronic terminal device, and then operate the electronic document related programs to browse, I had to edit.

However, in recent years, a wireless Internet environment has been established in which a broadband Internet environment is established and a user can access the Internet anytime and anywhere. Thus, by providing an electronic document related service to an electronic terminal device serving as a client terminal through a remote server, A web-based electronic document service that allows an electronic document to be viewed, created, and edited anytime and anywhere without installing a predetermined electronic document-related program in the electronic terminal apparatus is emerging.

Such a web-based electronic document service enables various client terminals to access an electronic document service providing server, browse an electronic document based on a markup language through a browser, and then create and edit the corresponding electronic document And it is mainly utilized in companies and organizations in that various client terminals support simultaneous collaboration on the electronic document in real time.

If a web-based electronic document service can be connected to the Internet without installing a predetermined electronic document creating program on the client terminal, the electronic document service can be browsed, created and edited through a browser installed in the client terminal And thus the mobility of users can be guaranteed, and the number of individual users is also increasing.

Generally, a web-based electronic document service converts an original electronic document into a markup language-based document in order to support a network-connected client terminal to edit an electronic document through a browser, The client terminal operates in a manner that performs editing of the markup language-based document through the browser.

In the case where the user 1 and the user 2 simultaneously edit the markup language-based document, while the client terminal of the user 2 is editing the markup language-based document through the browser, An editing command is transmitted to the server of the user 1 and the markup language based document of the remote server is synchronized with the markup language based document of the client terminal of the user 2. At the same time, Synchronization between the markup language based document of the server of the user 1 and the markup language based document of the client terminal of the user 1 is performed.

At this time, some editing commands for the markup language-based document may not be supported by the client terminal of the user 1 from the client terminal of the user 2 in accordance with the version of the office or the authority of the office running on the browser. If some unsupported editing commands are received, the editing instruction may be reflected in the markup language based document of the client terminal of the user 1, but may not be properly displayed on the client terminal of the user 1. In this case, if the user 1 inputs a command to execute again or a command to revert, some data on the object of the markup language-based document may be damaged. Accordingly, execution results such as a "return" function or a "redo" function different from the intention of the user 1 can be output.

Therefore, it is necessary to introduce an algorithm for ensuring editing reliability in which a 'return' function and a 'redo' function are performed as the user intends by performing a conversion operation differently depending on whether or not an editing command received from another user is supported .

The device for assuring the editing reliability of the unsupported editing command from the remote location according to the present invention and the method of operating the same are stored in the reverting buffer and the re-executing buffer based on whether the second editing command receiving section supports the newly received editing command By performing the conversion operation for the rewrite instruction and the rewrite instruction, even if the editing command from the other user is a non-editing instruction, it is possible to perform the 'revert' function and the 're- do.

An apparatus for assuring the editing reliability of a non-supported editing command from a remote location according to an embodiment of the present invention includes a markup language-based document receiving unit for receiving a markup language-based document for an original electronic document from an electronic document storage server, A second edit command receiving unit for receiving an edit command for the markup language based document from the electronic document save server, a second edit command receiving unit for receiving an edit command for the markup language based document, A rewrite buffer for sequentially storing a rewrite command corresponding to the edit command received by the first edit command receiver, a rewrite buffer for sequentially storing a rewrite command corresponding to the edit command received by the first edit command receiver, The execution buffer and the newly received edit command Includes on the basis of the support of the command return the buffer and the buffer is re-stored in the execution command and return parts of the operating transform to perform a conversion operation on the re-execution instruction.

[

Hereinafter, the structure of the editing reliability assurance devices 30 and 40 according to an embodiment of the present invention will be described in detail with reference to the drawings shown in FIG.

2 is a diagram showing the structure of the editing reliability assurance device 200 in detail.

2, the editing reliability assurance apparatus 200 includes a markup language-based document receiving unit 210, a markup language-based document storage unit 220, a first editing command receiving unit 230, An operation conversion unit 250, a re-execution buffer 260, a reverting buffer 270, and an edit command transmission unit 280. [0031]

The markup language-based document receiving unit 210 receives the markup language-based document generated by the electronic document storage server 50 based on the original electronic document from the network-connected electronic document storage server 50, Based language document in the markup language based document storage unit 220. [ Here, the markup language-based document storage unit 220 may be implemented as a memory device such as a dynamic random access memory (DRAM), a static random access memory (SRAM), or the like.

The first edit command receiving unit 230 receives an edit command corresponding to an input signal input by the user through the input device. Here, the input device is an input device such as a keyboard, a mouse, a touch screen, or an electronic pen connected to the editing reliability assurance device 200, and can generate an editing command based on the input signal inputted by the user. For example, when the user inputs " 12 " using an input device (e.g., a keyboard), the input device generates an edit command to insert " 12 " 230) may receive an edit command to insert " 12 " from the input device. If the user inputs " 3 " using an input device (e.g., a keyboard), the input device generates an edit command to insert " 3 "Quot; 3 " from the input device. Accordingly, " 123 " can be inserted in the markup language-based document. The edit command transmission unit 280 can transmit the edit command received by the first edit command reception unit 230 to the electronic document storage server 50. [

The second edit command receiving unit 240 can receive the edit command generated by the edit reliability assurance apparatus of another user through the electronic document storage server 50. [ For example, the second edit command receiving unit 240 may receive an edit command to insert a " 4 " into the markup language-based document via the electronic document storage server 50. [ Accordingly, the markup language-based document can be edited from " 123 " to "1234 ".

The operation conversion unit 250 edits the markup language-based document based on the edit command. For example, the operation conversion unit 250 inserts a " 12 " into a markup language-based document based on an edit command to insert " 12 " from the first edit command reception unit 230, Based document by inserting " 3 " in the markup language-based document based on an edit command to edit and insert a " 3 ". Further, the operation conversion unit 250 edits the markup language-based document by inserting " 4 " into the markup language-based document based on the edit command to insert "4" from the second edit command receiving unit 240 It is possible.

Also, the operation conversion unit 250 generates a re-execution command and a rewrite command corresponding to the editing command input from the first editing command receiving unit 230, and transmits the generated re-execution command and rewrite command again to the execution buffer 260. [ And the revertive buffer 270, respectively.

Specifically, the operation conversion unit 250 stores again the execution command corresponding to the editing command input from the first editing command receiving unit 230, in the execution buffer 260 again. The operation conversion unit 250 stores a revertive command corresponding to the edit command inputted from the first edit command receiving unit 230 in the revertive buffer 270. [ Accordingly, the re-execution buffer 260 sequentially stores re-execution commands corresponding to the edit command for the mark-up language-based document from the electronic document storage server 50, and the re- A revert instruction corresponding to an edit command for the markup language-based document from the edit server 50 may be sequentially stored. Here, the redo buffer 260 and the redo buffer 270 may be implemented as memory devices such as DRAM, SRAM, and the like.

For example, an editing command to insert "1" at the first position of the markup language-based document from the first editing command receiving unit 230, an editing command to insert "2" at the second position, 3 " and an edit command to insert " 4 " at the fourth position are sequentially inputted, the operation conversion unit 250 converts the first position 2 "in the second position," 3 "in the third position," 4 "in the fourth position, and" 4 "in the second position, Insert a character. At the same time, the operation conversion unit 250 may generate a re-execution command and a rewrite command corresponding to the editing commands as shown in Table 1, and store the same in the execution buffer 260 and the reverting buffer 270, respectively. Here, an object refers to various contents such as a graphic, an image, a table, a text, and the like that can be inserted into a markup language-based document.

order Redo buffer Revert Buffer One INS o [1] '1' DEL o [1] 2 INS o [2] '2' DEL o [2] 3 INS o [3] '3' DEL o [3] 4 INS o [4] '4' DEL o [4]

Referring to Table 1, "1", "2", "3" and "4" are stored in the first position o [1], the second position o [ 1] ', INS o [2]' 2 ', respectively corresponding to these in the execution buffer 260 by editing commands to insert them into the fourth position o [4] DELo [2], DELo [3], and INo [4] are sequentially stored in the rewrite buffer 270, , DEL o [3] and DEL o [4] are sequentially stored. Here, the redo command INS o [1] '1' is an editing command for inserting the character '1' into the first position, and the redo command INS o [2] '2' To the second position. Similarly, the redo command DELo [1] is an edit command to delete an object at the first position, and the redo command DELo [2] is an edit command to delete an object at the second position.

Also, the operation conversion unit 250 converts the markup language-based document 301 having the character " 1234 " inputted thereto from the first edit command reception unit 230 and / or the second edit command reception unit 240 When the position of the target object (i.e., " 1 ", " 2 ", " 3 ", and " 4 ") of the editing command that has been previously input is changed by the editing command, the execution buffer 260 and the reversion buffer 270) and the rewrite command for the object whose position is changed on the markup language-based document and the position information included in the rewrite command are changed by the new edit command The position can be changed to correspond to the position. In this case, when a new editing command is input from the first editing command receiving unit 230, the operation converting unit 250 generates a revert command and a re-executing command corresponding to the new editing command, And the revertive buffer 270, respectively.

For example, if an editing command to delete the objects at the first and second positions of the markup language-based document 301 is input from the first editing command receiving unit 230 in the situation as shown in Table 1, 250) deletes "12" from "1234" of the markup language-based document 301 and edits it to "34", and then returns a rewrite command corresponding to the edit command for "3" (I.e., o [3] and o [4]) included in the redo command are changed to correspond to positions (i.e., first and second positions) changed by the new edit command. Also, the operation conversion unit 250 outputs a revert instruction (NO-OP) whose position information is o [1] and o [2] by an edit command to delete the object at the first and second positions, Can be processed. Accordingly, the execution buffer 260 and the return buffer 270 can be updated as shown in Table 2 below.

order Redo buffer Revert Buffer One NO-OP NO-OP 2 NO-OP NO-OP 3 INS o [1] '3' DEL o [1] 4 INS o [2] '4' DEL o [2] 5 DEL o [1: 2] INS o [1] '12'

Referring to Table 2, an edit command to delete objects in the first and second positions o [1: 2] causes the execution buffer 260 to again execute DEL o [1: 2] Commands are stored, and the rewrite buffer 270 stores a re-execution command INS o [1] '12' corresponding to each of them. 3 ', INS o [4]' 4 ', DEL o [3]' 3 'and INS o [4]' 4 'corresponding to the edit command for the object positions "3" ] And DEL o [4] to INS o [1] '3', INS o [2] '4', DEL o [ (INS o [1] '1' and INS o [2] '2') and revert commands (ie, DEL the re-execution instruction DEL o [1: 2] is executed in the first and second positions o [1: 2] The INS o [1] '12' is an editing command to delete an object, and the redo command 'INS o [1]' 12 'is an editing command to insert "12" into the first position o [ Quot; is executed, a markup language-based document has a state where " 1 " is inserted at the first position and " 2 " is inserted at the second position It is.

Hereinafter, a specific operation method of the apparatus 200 for assuring security of editing according to an embodiment of the present invention will be described in detail with reference to an edit command. An edit command (hereinafter, an underline command) Is an editing command that is not supported by the device 200 (i.e., a non-editing command).

The operation conversion unit 250 determines whether or not the newly received edit command is supported by the second edit command receiving unit 240 and determines whether the newly received edit command is supported or not by referring to the revertive buffer 270 and the re- And performs a conversion operation on the rewrite instruction and the rewrite instruction stored in the memory 260. [ If the position of the target object of the editing command that has been previously input is changed by the newly inputted editing command, the conversion operation is performed by the reverting buffer 260 and the reverting buffer 270, And changing the position information included in the rewrite command and the rewrite command for the object whose position on the markup language based document is changed among the rewrite commands to be changed by the new edit command.

Specifically, when the new edit command from the second edit command receiving unit 240 is a support edit command, the operation converting unit 250 converts the first edit command received by the first edit command receiving unit 230 or the second When the position of the target object of the edit command inputted previously is changed from the edit command receiving unit 240, the revertive command stored in the revertive buffer 270 and the revertive buffer 260, The position information included in the rewrite command and the rewrite command for the object whose position has been changed is changed to correspond to the position changed by the new editing command. Here, the support edit command refers to an instruction that can perform an edit operation on a markup language-based document and display the result. On the other hand, the unsupported editing command refers to an instruction that can not perform an editing operation on a markup language-based document, or can not display the result even when performing an editing operation on the markup language-based document. In addition, the unsupported editing command that can not perform the editing operation for the markup language-based document may not be able to perform the rewriting operation or the rewriting operation because the operation conversion operation for the rewriting instruction or the rewriting instruction is not defined And an edit error occurs when performing an execute operation or a revert operation).

For example, if an edit command to insert "a" at the second position of the markup language-based document 302 is input from the second edit command receiving unit 240 in the situation shown in Table 2, the operation converting unit 250 Quot; a " in the markup language-based document 302 is inserted at the second position and edited as " 3a4 " (I. E., O [2]) included in the rewrite instruction and the rewrite instruction corresponding to the edited instruction for the changed " 4 " Change it. Accordingly, the execution buffer 260 and the return buffer 270 can be updated as shown in Table 3 below.

order Redo buffer Revert Buffer One NO-OP NO-OP 2 NO-OP NO-OP 3 INS o [1] '3' DEL o [1] 4 INS o [3] '4' DEL o [3] 5 DEL o [1: 2] INS o [1] '12'

Referring to Table 3, the rewrite command corresponding to the edit command for " 4 " in which the position of the object is changed by the edit command to insert "a" of the second position o [2] 2] is changed from '4' and DEL o [2] to INS o [3] '4' and DEL o [3]. As illustrated in FIG. 3, the markup language based document 303 is edited from " 34 " to " 3a4 ".

If the new editing command from the second editing command receiving unit 240 is a non-original editing command, the operation converting unit 250 clears the reverting buffer and the re-executing buffer.

For example, in the situation shown in Table 3, if an editing command to underline an object at the first to third positions of the markup language-based document 302 is input from the second editing command receiving unit 240, As described above, since the editing command for underlining an object is a non-editing command, the operation converting unit 250 clears the reverting buffer and the re-executing buffer. Accordingly, the execution buffer 260 and the return buffer 270 can be updated as shown in Table 4 below. 3, the markup language-based document 304 is edited from " 3a4 " to " 3a4 " by an editing command to underline an object at the first to third positions, Quot; 3a4 " in the display device provided in the apparatus 200 for assuring security of editing.

order Redo buffer Revert Buffer One

Referring to Table 4, the execution buffer 260 and the return buffer 270 are cleared so that the five previously stored rewrite instructions and rewrite instructions are deleted.

The editing reliability assurance apparatus 200 according to an embodiment of the present invention as described above may further include a reversion buffer 270 and an execution buffer 260 and the re-execute command, the 'return' function and the 're-execute' function are executed as the user intends, even if the edit command from the other user is the non- To ensure the reliability of editing.
