Hereinafter, with reference to the drawings will be described in detail the spirit and preferred embodiments of the present invention.

The text editor is a tool for editing information such as Microsoft Word processes, forms, and information with objects such as pictures and tables, and tools for editing text documents such as a programming editor or notepad (windows notepad program). Take control.

The editing method according to the present invention allows two or more people to edit a document simultaneously by sharing one document. This is not a form of working with a copy of the same document, but working with a single document at the same time in real time. In other words, when user A is editing Z, user B can also edit Z.

In this case, each screen that the user is editing may coincide with user A and user B at the same time. That is, when user A is editing 1 line, user B is editing 10 lines at the same time, and the contents of user A are being displayed on the edit screen in real time. Of course, the same line can be edited by multiple people. In addition, users can communicate with each other through the basic chat system while sharing and editing two or more documents.

This is similar to the principle of showing each other what they are doing while playing games in the same area, like online games like Lineage, and talking to them. This not only solves the hassle of making corrections for several people on a single document, but also allows for joint document management online.

In addition, two or more people share and edit a document, and through the advanced chat function among the additional functions provided by the present invention, users can exchange data with each other by using a file transfer function while talking to each other. Here, an advanced chat is a chat system that has a file transfer function in addition to a simple chat function.

This makes it possible to simultaneously edit documents between people who are not within a company but between regions (or countries).

For example, it is possible for user A in China and user B in Korea to simultaneously edit a document in real time. That is, the existing editors, while user A in China is working on the document, user B was not able to watch and edit the same, but the editing method according to the present invention makes it possible.

When the program developer uses the editing method according to the present invention, for example, when the developer A is in China and the developer B is developing in a certain program while in Korea, the development of the program is delayed due to the difficulty of communication. May be delayed.

However, according to the present invention, A developer shares the program source with other B developers while editing the program source, so that B developer watches the above program source with A developer and remotely assists and edits A developer in real time. The way is possible.

In the version control system for many developers, such as CVS (Concurrent Versions System) has been managed only in the form of working and synchronizing up and download the source in the past, according to the present invention, collaboration is more efficient in real time. Can proceed.

In the present invention, the number of editable users at the same time is theoretically infinite.

1 is a reference diagram for explaining a method for jointly editing a document by a plurality of users according to the present invention and the overall configuration in which the system operates.

In the environment in which the present invention operates, there may be a plurality of clients 101, 102, and 103, and there is one server 103 in which a document to be edited is stored.

In this case, the client refers to a program or user or a computer on which the above program operates. For example, Windows uses Internet Explorer to access the Internet, which requires you to enter a home page address and press the Enter key to ask the web server for the home page. At this time, Internet Explorer itself or the user's computer running the explorer can be called a client in relation to receiving (or returning) the requested HTML file, while actually handling the computer's request, such as sending and receiving HTML files. A thing (a program or a computer running it) is a server.

In the present invention, the client (in the present specification, the term console is used together with the same term as the client term) is a program (or a program in which the program is operated) that provides a user interface environment in which a user can edit a document. The server is a user computer, and a server is a program (or a predetermined computer on which the program operates) that allows two or more clients to access and edit a document and to manage the connected user and the owned document.

The client / server concept according to the present invention is similar to the client / server concept used in online games such as Lineage, but has not been utilized for this purpose in existing editors.

Meanwhile, according to the present invention, since a client and a server may exist in one computer, a document may be edited in the same manner as an existing document editor, and multiple users may share a document online and simultaneously edit the same document together. have. For example, if a client and a server are installed together on A computer, it is the same as the existing editor. In this state, when another user connects to the server installed on computer A, simultaneous editing with the user of computer A becomes possible.

A method and system for jointly editing a document by a plurality of users according to the present invention can be operated in a local computer environment, a LAN environment or an Internet environment.

2 is a block diagram of a preferred embodiment of a client of a system in which multiple users jointly edit a document in accordance with the present invention.

In the present invention, the client is composed of a message transmitting and receiving unit 201, the screen processing unit 202, the input processing unit 203 may further include an additional function processing unit (204).

The message transmitting and receiving unit 201 performs a function of transmitting or receiving a message (information) necessary between the client and the server. In the present invention, the communication method between the client and the server is preferably a session method. When the connection between the client and the server is made in this manner, the communication path is logically maintained, so when the server receives a message, the client information transmitted the message. To be able to extract.

The screen processing unit 202 performs a function of outputting the edited content on the screen in relation to the content received from the server. That is, when a predetermined message is received from the server through the message transmission / reception unit 201, whether the message is edit result information obtained by editing a document according to the editing command or a predetermined editing command transmitted from another client to the server. If the determination result is that the message is the edit result information, the edit result information is displayed on the screen to provide the user who edits the document.

The input processing unit 203 transmits the editing command to the server through the message transmitting / receiving unit 201 when the editing command for a predetermined document is received from the user.

The additional function processing unit 204 performs any one of chat or file transfer functions when the message received from the server through the message transmission / reception unit 201 is not the edit result information of the document. The chat, file transfer or document backup function provided by the present invention is the same as the conventional one (for example, MSN messenger), so the detailed description thereof will be omitted herein.

3 is a block diagram of a preferred embodiment of a server of a system in which a plurality of users jointly edit a document according to the present invention.

The server according to the present invention includes a message transmitting and receiving unit 301, a user management unit 302, a document authority setting unit 303, a message classification unit 304, OEP authority check unit 306, console-compatible document editing management unit 307 ), And an additional function processing unit 309, and may further include an OEP collecting unit 305 or an OEP log processing unit 308.

The message transceiver 301 performs a function of transmitting or receiving necessary messages (information) with clients in correspondence with the message transceiver 201 of FIG. 2.

The user manager 302 performs a function of managing information about a user who can access a server and edit a document.

The document-specific permission setting unit 303 may edit operations for each user or a user who is registered in the user management unit 302 or an anonymous user who is not registered in the user management unit 302. It receives information about documents and stores and manages them.

The user may access the server using a client computer by connecting anonymously without a user ID or by using a pre-registered user ID. In this case, the types of work that can be performed and the documents that can be edited are restricted according to the anonymous or ID registered in the server.

Restriction of permissions per document or user can be done by the root user, the administrator of the server, and it is desirable to allow the user of the document to be edited to restrict the permissions on the document.

The message classifying unit 304 performs a function of determining whether the received message is an editing command for a predetermined document after receiving a predetermined message from one of the clients.

The format of the message according to the protocol used in the present invention is described below.

In general, a protocol is a standardized communication protocol on a network. A protocol is a protocol that promises in advance what to do and how to communicate between two entities that want to communicate with each other in order to efficiently process a network.

The protocol used in the present invention is referred to as an online editing protocol (OEP) in the present specification, and the above OEP includes a protocol for communication between a server and a client regarding document editing, object insertion, editing position movement, user authority, and the like. In addition, the contents for performing additional functions provided in the present invention are also included in the above OEP.

In the present specification, the term OEP is sometimes used as a term meaning a message itself generated according to the OEP.

OEP is divided into query message, response message, and status message.

Query messages are usually used when a client requests a server, and a reply message is a response from the server to the client in response to a message requested by the client. A state message is a response to a request. The rest of the message (user, document status, broadcasting, etc.) outside of the response.

The size of the message used in the present invention is not fixed but is flexible for each message.

The format of the OEP message used in the present invention is as follows.

Message type: [message type] + [command] + [command argument]

The type of message may include a message requested from a client to the server, a message responding to a client request from the server, and a message from the server broadcasting edits to related clients.

The following describes some examples of each of the above messages.

1.Message from client requesting server to edit

CM_GETCHAR: Query the server for the character of the location in the object with the location information of the editor currently managed by the server.

Structure: [CM_GETCHAR]

CM_SETCHAR: Enter a character in the edit document.

Structure: [CM_SETCHAR] + [Character Size] + [Character Data]

CM_SETTEXT: Enter text (a sentence composed of multiple characters).

-Structure: [CM_SETTEXT] + [Text Size] + [Text Data to Set]

CM_GETTEXT: Reads the text of the document being edited and copies it to memory.

Structure: [CM_GETTEXT]

  CM_ADDLINE; Add a line

Structure: [CM_ADDLINE]

Etc. In addition, there may be various messages required for document editing.

2. Server Messages

 It is prefixed with the identifier r, which indicates the server's response to the client's message.

  For example, r + CM_SETTEXT is the response message to the client request to set the text.

r + CM_GETCHAR; response to CM_GETCHAR

-Structure = [r] + [CM_GETCHAR] + [character size] + [character data]

And the like. The response message of this server exists in response to the client's document editing command.

3. Status message

The identifier b is preceded by the client and the server, indicating that the content is being edited, that is, a message for broadcasting for synchronization purposes.

 b + CM_GETCHAR; Broadcasting message for CM_GETCHAR

 -Structure = [b] + [CM_GETCHAR] + [character size] + [character data]

And the like. This message also corresponds to the client's document editing command in the same way as the server's response message.

Broadcasting, for example, in a chat program where someone in the same room says 'Hello?' Should show 'Hello?' In the chat client dialog of everyone connected to the room. To do this, the server says 'hello?' When you receive a message, you have to deliver the text 'Hello?' To everyone connected to the room. Broadcasting something like this is called broadcasting at the same time.

The OEP authority checking unit 306 extracts user information from the client information that sent the message when the message is an editing command for the document, as a result of the determination of the message classification unit, and the preset editing right for the user information and the document. Based on the information, the user determines whether or not the user has a legitimate authority to edit the document. That is, the OEP authority checking unit 306, for example, if the OEP is an OEP related to editing and the authority of the user who instructed the OEP does not have the editing authority, the OEP authority checking unit 306 simply discards the OEP without processing.

The console-compatible document editing management unit 307 edits the document in response to an editing command of the message when it is determined that the user has the right authority to edit the document as a result of the OEP authority checking unit 306. Do this.

In addition, the console-compatible document editing management unit 307 may further perform a function of transmitting the edit result information performed above to all clients editing the document. In other words, the edit information can be broadcast.

In addition, it is possible to extract the position at which the editing is performed at the location of the document, to generate the location for performing editing, and to generate the client editing location information, which is the location information for editing the document for each client editing the document. The client may further perform a function of transmitting the editing result information by extracting a client whose client editing position is within a predetermined range based on the editing performing position.

In other words, it checks in which position the editing of the performed document is performed, extracts the position of performing edits, extracts the screen position information of other clients editing the document, compares the position information, and compares the position information in which the edit is performed. It may further perform a function of transmitting the editing result information by extracting the included clients.

The console-compatible document editing management unit 307 notifies the relevant console if the received OEP has been successfully processed. At this time, the document is edited and the changed contents are notified to other related consoles to match the displayed contents. You can broadcast it to make it work.

At this time, it may not be necessary to inform all users (clients) connected to the server when broadcasting. That is, only the user who is working on the same screen currently being worked on can tell the contents. For example, console A has 1-100 lines of working screen (part shown on editor screen), console B has 50-150 lines of working screen, console C has 200-300 lines of working screen. If you insert a character into a particular row on line 55 in the console, you don't have to tell C console about it. Also, if you insert a character in a specific column of line 5, you only need to pass it to console A. The same applies to other editing situations.

Meanwhile, the console document editing management unit 307 should store individual information corresponding to the edit screen displayed on the console. For example, the corresponding console must manage information such as work area and work location information. The shared document information being edited is stored in the edit document storage unit, which includes text attributes or object (picture, table, etc.) information for each line of the document being edited.

If the message classification unit 304 determines that the message is not an editing command for the document, the additional function processing unit 309 performs one of chatting or file transmission. This is a function for better user convenience in online multi-editing. The contents are as follows.

1. An online document multi-editing system naturally builds a basic chat system, but may require a chat system with better advanced features. In this case, a separate advanced chat protocol can be used to chat.

2. You may need to pass some reference files to each other. In this case, it is possible to provide a function of uploading / downloading files between users (or servers).

3. Other add-ons can be entered.

The OEP collecting unit 305 receives a predetermined message from one of the clients, stores the messages in the order in which they are received, and provides the message classification unit.

In more detail, the function of the OEP collecting unit 305 is performed to store OEPs received from each client in order to process the contents indicated by two or more clients. The received OEP is stored in the OEP queue.

A queue is a line in which some data is waiting to be processed, which is processed in order from the beginning of the line, and the processed data is removed. This is necessary for synchronization between the client (hereafter referred to as console) and server. If Console A and Console B edit the same line at the same time, information about these characters is sent to the server when both consoles type a character at the same time. But no matter how much information about a character is sent to the server at the same time, it is never actually received at the same time. An interval of 0.001 seconds can only exist. OEPs are stored in the OEP queue in the order they were first received.

The OEP collector sequentially provides the stored OEP messages to the OEP authorization checker 306.

The OEP log processing unit 308 performs a function of storing the edited content of the document as a log in the console corresponding document editing management unit.

If console A, console B, or servers are operated in different areas on the Internet rather than in the local LAN or local environment, the contents of console B may be delivered even if console A first directs the server according to the network environment. Can be. However, although the probability of such contents is gradually decreasing due to the development of the Internet, it is desirable to keep the edited contents logged as a means for the console to check them at any time. The log is a list of which OEPs are processed and in what order.

The contents of the OEP log are

'When console A inserted the letter C in line x of document A,'

'When console A added the letter C to the line y of document A,'

'Console A modified the letter C to the letter A on the y line of document A.'

... and so on. This content is managed as binary data and can be sent to the console when a particular console requires it.

It is preferable to use a stack as a format for storing logs in the OEP log processor. In this case, a stack is a data structure that processes the last stored item first and removes the processed data. A log is a record of what a user has done and is used for the Undo / Redo function. What is stored on the stack is also associated with the Undo / Redo feature. In other words, by referring to this log, Undo is performed by performing the reverse of the log record, and Redo is performed by reversing the log again.

Figure 4 is a flow chart of a preferred embodiment of the method for illustrating a method for setting the editing authority for each document in the server of the present invention. This embodiment is a case where the user sets the authority for his document stored in the server.

First, the client connects to the server and undergoes user authentication 401 using a user ID, password, and the like.

When the client access and user authentication is normally performed, the server displays a list of documents stored in the server to which the user can set authority. Read from the stored edited document storage unit 402 and transmits it to the client.

The server reads the user information that is currently registered as a user (403) and transmits it to the client.

The client outputs the received list information and the user information on the screen, stores them in the user, selects some documents in the above list, and selects a user to give permission to edit the above documents, and transmits them to the server.

The server grants 405 editing rights to the selected user for the selected document. This editing authority setting is reflected in the above edited document storage and shared document storage.

5 is a flow diagram of a preferred embodiment of a method for collaboratively editing a document by multiple users in a server of the present invention. This embodiment is based on the premise that the client of the user has already connected to the server and authenticated the user.

First, a predetermined message is transmitted from a predetermined console (client) (501) and it is determined (502) whether the above message is an OEP message related to document editing. If the determination result is an OEP message related to document editing, the message is stored in the order in which it is received (503).

Thereafter, the sender information is read from the above message, and the editing authority information of the above calling party (user) is read out 504, and then it is determined whether the above message corresponds to the editing authority (505).

As a result of the determination, if the above message matches the preset editing authority, the content of the document is edited 506 according to the content of the message. Thereafter, among the consoles editing the corresponding document, the edited result is transmitted to the consoles which belong to the current edit range (507).

Thereafter, the processed edits are stored in a log (508) according to the above message.

After that, it is determined whether the editing is finished, and if not, the flow proceeds to step 501.

On the other hand, if the message received in step 502 is not an OEP message related to document editing, the process proceeds to step 501 again after processing the additional function (510) in response to the contents of the message.

If the message does not correspond to the editing authority as a result of the determination in step 505, the received OEP message is discarded (511) and the process moves to step 509.

6 is a flowchart of a preferred embodiment of a method for collaboratively editing a document by multiple users in a client of the present invention.

The client connects to the server according to the user's command and performs the user authentication process (601).

Thereafter, it is determined whether or not a predetermined edit command is input from the user (602). If an input is made, the user receives an input (603) of the predetermined edit command, transmits it to the server (604), and then proceeds to step 605.

On the other hand, if it is determined in step 602 that the editing command is not input from the user, it is determined whether or not a predetermined message is received from the server (605). If it is received, it is determined whether the message is related to document editing (606). If true, the editing result of the received message is displayed on the screen and provided to the user (607).

If no message is received from the server in step 605, the process goes back to step 602.

If the message received from the server in step 6060 is not a message related to document editing, the process adds a function corresponding to the content of the message (608) and moves to step 602 again.

So far we looked at the preferred embodiment according to the present invention in detail. The scope of the present invention is not limited to the above-described embodiments, and will naturally extend if the technical idea of the present invention is applied.

Meanwhile, the methods of the present invention can be written in a program that can be executed by a computer, and the programs can be recorded in a computer-readable recording medium, that is, a hard disk, various memories, a floppy disk, a CD, and the like. Do.

According to the present invention, an area in which a user can access a communication network can simultaneously edit a document while talking to each other using a function of file transfer or a document by remote users without any local restrictions. There is. This saves time when a user edits a document jointly by multiple users, and also improves the quality of the document by unifying terms in the document.
