In addition, the present invention can also be applied to an editing server which judges a conflict between edited contents generated by different users occurring in an editing process to be edited, And synchronize the contents to improve the efficiency of document editing.

In addition, the present invention can also be applied to a case where a plurality of user apparatuses, which assign model servers 200 for document editing for each document and cooperate with the model server 200, To provide a connection to the model server 200 so that editing data received from a plurality of user apparatuses can be distributed by a plurality of editing servers to increase the processing speed for collaborative editing, .

The detailed operation of the document editing system for collaborative editing according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram illustrating the operation of a document editing system for collaborative editing according to an embodiment of the present invention. As shown in FIG. 2, a document editing apparatus 11 Can be connected to the editing server 100 and the editing server 100 can assign the model server 200 in correspondence with the editing target document selected by the document editing device 11. [

At this time, the editing server 100 may allocate the editing server 100 for different individual documents. For example, the editing server 100 receives the document identification information about the document to be browsed from the document editing device 11, Extracts and stores an edition target document corresponding to the document identification information from an external DB storing the document based on the information, and allocates the model server 200 in correspondence with the edition target document.

The document editing device 11 may include a renderer rendering a document to be edited and displaying the edited document through the user device. The document editing device 11 may include a user And generate event information for an editing event (or a command) according to a user's key input through the input unit.

When the event information is generated, the document editing device 11 generates edit request information including the event information, user identification information for a predetermined user, and document identification information for the document to be edited, (100).

At this time, the document editing device 11 edits the edit target document according to the edit type corresponding to the event information among the preset edit types, and then renders the edited target document through the renderer, And can be displayed through the display unit, which will be described in detail below with reference to the drawings.

Accordingly, the editing server 100 edits the document based on the editing request information received from each of the one or more document editing apparatuses 11, determines the conflict between the different editing request information as a result of the editing process, It is possible to cooperatively edit the document to be edited based on the edit request information received from the plurality of document editing apparatuses 11 in cooperation with the synchronization server 300. In detail, Explain.

First, the editing server 100 may include an editing control unit 110, a sequence management unit 120, and a common editing processing unit 130.

The editing control unit 110 can receive the editing request information according to the user's document editing of the editing target document through the communication network from the document editing apparatus 11 configured in the user apparatus, To the model server 200 allocated in correspondence with the document to be edited.

In addition, the model server 200 may receive the edit request information and edit the edit target document based on the event information included in the edit request information.

Thereafter, the model server 200 can generate editing result information according to the editing process of the editing target document, and can return the editing result information to the editing server 100 in the form of JSON (JavaScript Object Notation) have.

At this time, JSON is a lightweight data exchange format and can be used as a data structure of editing result information.

The editing result information may include at least one of an editing type corresponding to the event information, information about an editing target (or editing area) corresponding to the event information in the editing target document, And may include information on a result of processing an edit target in accordance with the event information. For example, the editing result information may be edited by editing the object, which is an editing object corresponding to the editing request information among the objects included in the editing object document, according to the editing request information, Or information on an editing result according to a state in which the object is replaced with another object.

When the editing server 100 accesses the model server 200 through the other editing server 100, the editing server 100 may access the editing server 100 from the document editing device 11 using the model server 200 configured in the other editing server 100 And transmits the received editing request information, and receives the editing result information corresponding to the editing request information.

In addition, the model server 200 may determine whether there is a conflict between the edit request information and the edit request information upon receiving the edit request information. For example, the model server 200 may determine whether an object corresponding to the edit request information It is determined that a collision has occurred in the edit request information if the edit request information is deleted by the other edit request information and the edit processing according to the edit request information is impossible.

Accordingly, the model server 200 can provide the editing control unit 110 with the determination result information as a result of the collision when the collision occurs, corresponding to the editing request information, The editing control unit 110 can provide the editing result information on the editing result corresponding to the information.

On the other hand, the editing control unit 110 checks whether there is a collision based on the editing result information corresponding to the editing request information from the model server 200, determines that an error has occurred when a collision occurs, (11) of the user apparatus that has transmitted the edit request information based on the included user identification information, generates error information according to the occurrence of the error, and generates error information corresponding to the identified document editing apparatus The error information can be transmitted to the user apparatus via the communication network and edited content corresponding to the edit request information corresponding to the error information can be excluded from the synchronization process without performing the subsequent process.

In addition, the document editing device 11 identifies the type of error information when receiving the error information corresponding to the edit request information transmitted to the editing server 100, It may request the document that has been most recently synchronized with the editing server 11 or may receive the document related information synchronized from the editing server 100 and render and display it.

For example, the document editing apparatus 11 may not proceed to the subsequent error information in response to an error in the editing process, such as an editing request for a deleted paragraph. In this case, the document editing device 11 synchronizes the editing target document based on the following editing list information, so that synchronization with the editing target document of another user is performed, have.

In addition, the document editing device 11 requests the editing server 100 to re-request the most recently synchronized whole document related information when an error occurs due to a failure such as a network failure or a time out, After receiving the document information about the most recently synchronized document from the server 100, the document information may be rendered and displayed to provide for subsequent editing. At this time, the document editing apparatus 11 can output a failure related message if the re-request fails. After the editing screen is temporarily locked, if the network is normalized, the document editing apparatus 11 requests the document information again and renders the received document information And can be provided to allow normal editing to be performed.

The editing control unit 110 deletes at least one of the editing request information and the editing result information at the time of occurrence of an error based on the editing result information corresponding to the editing request information, It can be prevented from being reflected in the editing target document of the apparatus.

On the other hand, the editing control unit 110 generates editing information based on the editing request information and the editing result information when no error occurs in the editing request information based on the editing result information (if no conflict occurs) The sequence management unit 120 configured in the editing server 100 provides the editing information to set a sequence for the editing information according to communication between the sequence management unit 120 and the synchronization server 300 .

3, the sequence management unit 120 extracts the document identification information included in the edit information in order to set a sequence to the edit information when receiving the edit information from the edit control unit 110, And may provide the sequence request information for the sequence request including the document identification information to the synchronization server 300.

At this time, the editing information may include the editing result information and the user identification information and the document identification information included in the editing request information.

The synchronization server 300 is connected to the editing server 100a through other editing servers 100b to 100n other than the editing server 100a connected to the document editing apparatus 11, (Receive) other editing information set in sequence with respect to the editing target document corresponding to another user apparatus connected to the model server 200 of the editing server 100, from the other editing servers 100b to 100n, (Sequential numbers) corresponding to the editing information in accordance with the order in which the editing information is received (in accordance with the repair line where the editing information is received).

Accordingly, upon receiving the sequence request information from the sequence management unit 120 of the editing server 100a, the synchronization server 300 identifies the document to be edited based on the document identification information included in the sequence request information, If there is already received other editing information corresponding to the editing target document at the time of information reception, identifies the last sequential number by confirming the sequence (order number) set for each of the already existing other editing information, Can be assigned to the sequence information corresponding to the sequence request information received from the sequence management unit 120. [

The synchronization server 300 may transmit the sequence information including the assigned sequence number to the sequence management unit 120 of the editing server 100a that transmitted the sequence request information.

The editing control unit 110 of the editing server 100a receives the sequence information of the editing information from the sequence management unit 120 of the editing server 100a, It is possible to set the sequence number according to the sequence information received from the server 300 as a sequence for the edit information and to provide the edit information set in the sequence to the synchronization server 300.

Accordingly, the synchronization server 300 can receive and collect edit information corresponding to a sequence corresponding to the edit target document from one or more edit servers 100a to 100n, and the one or more edit servers 100a to 100n can collect the edit information, It is possible to provide edit information set in each sequence as common editing information.

That is, the synchronization server 300 is configured to synchronize the contents of the specific editing target document with the contents edited by the user other than the contents edited by the user, The editing contents of a plurality of users for a specific editing target document can be collected and the order of the editing contents can be assigned according to the receiving order so that the editing contents can be reflected in order.

Accordingly, the synchronization server 300 can provide the editing server 100a with the editing information set in sequence received from the other editing servers 100b through 100n in correspondence with the specific editing target document as the common editing information, Editing information received from the editing server 100a may also be generated as common editing information and transmitted to the editing server 100a.

At this time, the synchronization server 300 can control not to repeatedly transmit the same editing information to the specific editing server 100, and the editing server 100 can store the set editing information received from the editing server 100 , And if the edit information set in the sequence is transmitted as the common edit information to each of the one or more edit servers 100a to 100n, the edit information set corresponding to the common edit information may be deleted.

In addition, the synchronization server 300 can count and manage the sequence separately from the deletion of the edit information set in the sequence.

Also, the common edit information may include the edit result information, the document identification information, the user identification information, and the sequence.

2, the common editing processing unit 130 configured in the editing server 100 generates document identification information corresponding to the editing information under the control of the editing control unit 110, (300) for receiving at least one piece of different common editing information including the document identification information corresponding to the same editing target document from the synchronization server (300) And compiles one or more pieces of different common edit information in order to generate edit list information and transmits the edit list information to a document editing apparatus 11 corresponding to the edit information in a web socket- ) To the configured user equipment.

At this time, the common edit processing unit 130 may reduce the amount of data to be transmitted to the document editing apparatus 11 by merging a plurality of common editing information included in the edit list information, The speed of the editing process of the document to be edited can be increased. This will be described in detail with reference to FIGS. 4 and 5. FIG.

4, the common edit processing unit 130 records the common edit information received from the synchronization server 300 in a buffer allocated in correspondence with the document identification information of the edit target document, The editing list information can be generated by collecting a plurality of common editing information recorded in the buffer.

The cooperative edit processing unit 130 may further include a merge processing unit 131 for merging mergeable data in the edit list information. The merge processing unit 131 may include a plurality of co- The plurality of pieces of common editing information having the same editing target of the editing target document can be identified based on the editing target related information included in the common editing information among the editing information.

Accordingly, the merge processing unit 131 included in the common edit processing unit 130 can merge a plurality of pieces of edit information having the same editing target into one piece of edit information according to a preset rule, Can be updated.

For example, as shown in FIG. 5, the merge processing unit 131 adds new text to paragraph 1 according to the common edit information corresponding to the first sequence of the plurality of common edit information included in the edit list information The editing result of sequentially reflecting the plurality of common edit information corresponding to the third and fifth sequences for which the text of paragraph 1 is to be edited in paragraph 1 in order, except for the common edit information corresponding to the third sequence, It is not necessary to reflect the third editing content (the editing result), so that the third co-editing information is merged with the fifth co-editing information as shown in the figure .

In addition, the merge processing unit 131 deletes the joint edit information having the third sequence from the edit list information, or deletes the edit result information from the third joint edit information, and performs the edit processing according to the third joint edit information Can be prevented.

As described above, the common edit processing unit 130 identifies a plurality of common editing information having the same editing target, and outputs editing results in accordance with one of the plurality of common editing information identified, If the editing results according to the editing information are the same, it is possible to reduce the data of the editing list information by merging into one piece of common editing information.

In addition, the common edit processing unit 130 may transmit the edit list information to the document editing apparatus 11 of the user apparatus. The common edit processing unit 130 may transmit a plurality of different user apparatuses participating in editing of the edit target document, The identification information included in each editing request information included in each edit request information received by the editing server 100, or the identification information included in each of the plurality of different editing request information included in the editing request information received by the editing server 100, By transmitting the edit list information to the user device, it is possible to synchronize the document to be edited between any of the web browser-based document editing apparatuses 11 configured in different user apparatuses.

At this time, the common edit processing unit 130 deletes the editing result information and the remaining information excluding the sequence from the common edit information included in the edit list information transmitted to the user device, and transmits the deleted information to the user device, It is possible to further reduce the amount of data to be transmitted.

Accordingly, the editing server 100 displays the editing target document, which is being edited jointly by a plurality of different users, equally to each user, and at the same time, supports the editing result to be accurately shared, .

The editing server 100 can reduce the amount of communication for each of the plurality of document editing apparatuses 11 by merging data according to the editing list information and transmitting the merged data on a web socket basis. So that the editing speed can be increased and the efficiency and response speed of the collaborative editing can be greatly improved.

In this case, the editing server 100 may operate to merge data by the merging processor 131 each time the editing list information is generated at a preset cycle.

2, the document editing apparatus 11 receives edit list information from the editing server 100, confirms a sequence set for the common edit information included in the edit list information, The editing target document can be edited and processed by sequentially reflecting the common editing information on the basis of the sequence of editing information, and the editing target document is edited on the basis of the common editing information included in the editing list information, A document to be edited can be rendered for each editing process and displayed on the display unit of the user device.
