1 is a diagram illustrating a configuration of an electronic document editing apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 1, an electronic document editing apparatus 100 according to an embodiment of the present invention may include an electronic document requesting unit 110, an electronic document receiving unit 120, an electronic document storage unit 130, and an editing command receiving unit 140. ) And an editing command transmitter 150.

First, when the user 210 requests reading of the electronic document selected by the web browser through the input device, the electronic document requesting unit 110 selects the electronic document selected by the user 210 stored in the electronic document storage server 230. The document may be requested to the electronic document storage server 230. Here, the electronic document stored in the electronic document storage server 230 may be configured as shown in Table 1 below.

Parent group Subgroup individual Object id Object value key value Format group Font group Object ID 1 "height" 1000 "textColor" "# 000000" ... ... ... ... ... Style group Object ID 2 “Type” "PARA" "name" "Desktop" ... ... ... ... ... ... ... ... ... Content group Paragraph group Object ID 3 "nextPara" Object ID 4 "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" Hangul ... ... Object ID 4 "nextPara" - "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" and ... ... ... ... ... ...

Here, the electronic document is composed of a plurality of groups each comprising a plurality of entities, the plurality of groups comprising a form group and a content group, each of the plurality of entities including an entity ID and an entity value. can do. Herein, the format group may include various sub-groups such as a format group representing letter shape information and a format group representing tab shape information. Meanwhile, each of the entities may be data in a key-value format in which an entity ID is a key and an entity value is a value.

Form groups contain objects that represent information about document formatting, such as glyph information, tab shape information, paragraph number shape information, bullet shape information, paragraph shape information, style information, and so on. It can mean shapes, images, tables, texts, etc. In addition, the format is to indicate the color, shape, etc. of the content. If the content is text, the font, color, size, etc. of the text may be referred to as the format for the text content. If the content is a table, the format is included in the table. The color of the cells, etc., can be said to be the format for the table contents. Meanwhile, in the case of a figure, one content is provided for each figure, and in the case of a table, the content is one content, and a figure, an image, a table, text, etc., inserted in the table is one content each, and in the case of text, a word having the same format, A string of a predetermined length may be one piece of content.

In addition, the entity ID of the form group and / or content group may include time information (eg, time information according to a server time of the electronic document storage server 230 and / or local time of the electronic document editing apparatus 100) and the user ( It is generated by concatenating the user identification number of 210, and the duplicate avoidance number may be further concatenated in order to distinguish between entities having the same time information and the user identification number, that is, avoid the overlap. For example, the entity ID of the form group and / or content group may be generated as shown in Table 2 below.

Object id Time information User id Duplicate avoidance number Object ID 1 Time information 1 User ID 1 00 Object ID 2 Time information 1 User ID 1 01 Object ID 3 Time information 2 User ID 1 00 Object ID 4 Time information 2 User ID 2 00 ... ... ... ...

Here, the duplicate avoidance numbers may be differently assigned to distinguish between entities having the same time information and the user identification number, such as entity IDs 1 and 2. In this case, an initial duplicate avoidance number (eg, 00) is assigned to the first entity ID, and a duplicate avoidance number increased by 1 from the duplicate avoidance number assigned to the previous entity ID is assigned to the next entity ID. And duplicate avoidance numbers for differentiation between entities having the same user identification number. However, if the time information is different even when the user ID is the same (Object IDs 2 and 3) and when the user ID is different even when the time information is the same (Object IDs 3 and 4), the initial duplicate avoidance number (that is, 00) Can be assigned. Here, the overlap avoidance number is illustrated as being two digits, but this is only an example and may have a preset length of one digit or two or more. Next, as shown in Table 1, the entity value may have a value of a key-value format. For example, an object value of an object included in a format group representing letter shape information in the format group may be “height”: 1000, “textColor”: “# 000000”, where “height” and “textColor” May be a key, and 1000, “# 000000” may be a value. In addition, the object value of the object included in the format group indicating the glyph information of the format group is “nextPara”: "Object ID 4", "Flag": 0, "charShape": Object ID 1, "styles": Object ID 2, "contents": Hangul, where "nextPara", "Flag", charShape "," styles ", and" contents "can be keys," Object ID 4 ", 0," Object ID 1 " , “Object ID 2” and Hangul may be a value.

The electronic document receiving unit 120 may receive the electronic document transmitted by the electronic document storage server 230 in response to a request for viewing the electronic document selected by the user 210.

Next, the electronic document storage unit 130 may temporarily store the electronic document received by the electronic document receiving unit 120. Here, the electronic document storage unit 130 may be implemented as a memory device such as a dynamic random access memory (DRAM), a static RAM (SRAM), etc. which may temporarily store the electronic document.

The editing command receiving unit 140 may be configured to respond to an input signal input by the user 210 through the input device while the web browser displaying the electronic document temporarily stored in the electronic document storage unit 130 is activated. A corresponding edit command can be received. Here, the input device may generate an editing command based on the input signal input by the user 210. For example, when the user 210 inputs “one” by using an input device (eg, a keyboard), the input device generates an editing command for inputting “one” into the electronic document, and the editing command receiving unit 140 ) May receive an editing command from an input device. In addition, when the user 210 inputs a “writing” using an input device (eg, a keyboard), the input device generates an editing command for inputting the “writing” in the electronic document, and the editing command receiving unit 140 An editing command can be received from the input device.

The editing command receiving unit 140 may edit the electronic document stored in the electronic document storage unit 130 based on the received editing command.

Next, the edit command transmitter 150 may transmit the edit command received by the edit command receiver 140 to the electronic document storage server 230.

In this case, the electronic document storage server 230 may update the electronic document according to the type of the editing command transmitted by the editing command transmitter 150.

In detail, when the type of the editing command sent by the editing command transmitter 150 is a new content input command, the electronic document storage server 230 generates objects included in the content group among the plurality of groups. The electronic document may be updated by including the created entities in a content group of the plurality of groups. In addition, when the electronic document storage server 230 includes newly created objects in the electronic document, the value of some object values among the object values of the existing objects (eg, a value of a key for referring to an object ID of a specific object) ) Can be updated to indicate the entity IDs of newly created entities.

For example, if the electronic document storage server 230 receives a new content input command for inputting the text content of the computer into the next paragraph of the paragraph indicated by the entity having the entity ID 4, the electronic document storage server 230 receives the electronic document as shown in Table 1 above. It can be updated as shown in Table 3.

Parent group Subgroup individual Object id Object value key value Format group Font group Object ID 1 "height" 1000 "textColor" "# 000000" ... ... ... ... ... Style group Object ID 2 “Type” "PARA" "name" "Desktop" ... ... ... ... ... ... ... ... ... Content group Paragraph group Object ID 3 "nextPara" Object ID 4 "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" Hangul ... ... Object ID 4 "nextPara" Object ID 5 "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" and ... ... Object ID 5 "nextPara" - "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" computer ... ... ... ... ... ...

Here, referring to Table 3, the electronic document storage server 230 sets the value of the "nextPara" key among the entity values of the entity having the entity ID 4 in response to the update of the entity having the entity ID 5-(the former In the last paragraph of the document). Here, the "nextPara" key may be a key for indicating the entity ID of the entity for the next paragraph of the paragraph represented by the entity.

Meanwhile, when the edit command sent by the edit command transmitter 150 is a new content input command, the electronic document storage server 230 extracts content related information from the new content input command and includes entities of entities to be included in a content group. A value, and the time information (in the case where the object ID is generated in the electronic document storage server 230, the time information may be used as the server time of the electronic document storage server 230) and the user of the user. The electronic document may be updated by generating entities to be included in the content group by concatenating an identification number and generating entities to be included in the content group, and then including the created entities in the content group.

Herein, the content-related information in the new content input command includes content content (eg, text that is a computer entered by the user 210 through the input device) and content location (eg, that the user 210 uses a computer through the input device). Position of the cursor when inputting text), and accordingly, the electronic document storage server 230 sets a value of a key indicating content content among object values as content input by the user 210 through the input device. And by setting the value of the key indicating the content position to the position of the cursor when the user 210 inputs the content through the input device, the object value of the entities to be included in the content group can be generated. Meanwhile, the entity value other than the content related information of the entities to be included in the content group may be set to have an entity value indicating a default value.

Next, the electronic document storage server 230 concatenates the time information and the user identification number of the user to generate an entity ID of entities to be included in the content group, and duplicates avoiding numbers in the time information and the user identification number. May be further concatenated to generate entity IDs of the entities. In this case, the electronic document storage server 230 may generate entity IDs of the entities such that duplicate avoidance numbers of the entities have different values. For example, the electronic document storage server 230 has an initial duplicate avoidance number of an object ID of a first object among simultaneously created objects, and an object ID of a next object from a duplicate avoidance number of an object ID of a previous object. The entity IDs of the entities may be generated to have a value of 1.

In addition, when the type of the edit command sent by the edit command transmitter 150 is a content delete command, the electronic document storage server 230 identifies the entities having the same entity ID as those of the target objects of the edit command. Thereafter, the electronic document may be updated by changing a flag value among the identified entity values to an on value. That is, the electronic document storage server 230 may easily perform a content deletion command by changing a flag value among object values of an entity whose type of the edit command sent by the edit command transmitter 150 corresponds to the content delete command. Can be.

For example, the electronic document storage server 230 may update the electronic document as shown in Table 3 as shown in Table 4 below when receiving a content deletion command for deleting a paragraph indicated by the entity having the entity ID 4. .

Parent group Subgroup individual Object id Object value key value Format group Font group Object ID 1 "height" 1000 "textColor" "# 000000" ... ... ... ... ... Style group Object ID 2 “Type” "PARA" "name" "Desktop" ... ... ... ... ... ... ... ... ... Content group Paragraph group Object ID 3 "nextPara" Object ID 4 "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" Hangul ... ... Object ID 4 "nextPara" Object ID 5 "Flag" One "charShape" Object ID 1 "styles" Object ID 2 "contents" and ... ... Object ID 5 "nextPara" - "Flag" 0 "charShape" Object ID 1 "styles" Object ID 2 "contents" computer ... ... ... ... ... ...

Here, as shown in Table 4, the electronic document storage server 230 sets the value of the flag key (ie, “Flag”) from 0 (ie, off) to 1 (ie, on) of the object value of the entity having the entity ID 4. By changing to, the electronic document can be updated.

On the other hand, the electronic document storage server 230 deletes the objects whose flag value is changed to an on value at predetermined time intervals or when editing of the electronic document of the user 210 is completed, thereby removing the objects from the electronic document. Eliminate objects that are no longer used to represent electronic documents. In this case, as the number of users simultaneously editing the electronic document increases, the preset time interval may be preset.

On the other hand, when the electronic document storage server 230 deletes objects whose flag value is turned on, if the value of any key among the object values refers to the object ID whose flag value is turned on, the flag value is turned on. The electronic document may be updated to refer to an entity ID referenced by the value of an arbitrary key among the entity values of the changed entity, so that the value of any key among the entity values referring to the entity ID whose flag value is turned on. For example, when the electronic document storage server 230 deletes an entity having an entity ID of 4,

Since the value of the "nextPara" key among the object values refers to the object ID 4 whose flag value is changed to on, the object ID 5 referred to by the value of the "nextPara" key among the object values of the object whose flag value is changed to on. The electronic document may be updated to refer to the value of the "nextPara" key among the entity values referring to ID 4. Accordingly, the value of the "nextPara" key among the entity values of the entity having entity ID 3 may refer to entity ID 5. Reference may be made.

Next, referring to FIG. 1, the electronic document editing apparatus 100 according to an embodiment of the present invention may further include an electronic document converter 160.

The electronic document conversion unit 160 may convert the electronic document editable in the web browser temporarily stored in the electronic document storage unit 130 as shown in Table 1 into an electronic document for a word processor program. In addition, the electronic document converter 160 may convert an electronic document for a word processor program into an electronic document that can be edited in the web browser, and then store the electronic document in the electronic document storage 130.

The electronic document converter 160 converts meta information of the electronic document into meta information of an electronic document for a word processor program, and converts objects included in a form group into a format object of an electronic document for a word processor program. By converting the objects included in the content group into the content object of the electronic document for the word processor program, the electronic document editable in the web browser can be converted into the electronic document for the word processor program. In this case, the electronic document converter 160 may determine the conversion order of the objects included in the format group and the objects included in the content group according to the reference order of the object ID. For example, the electronic document converter 160 determines the conversion order of the objects included in the format group and the objects included in the content group so that the conversion order of the object referring to the object ID of the electronic document has a higher priority than that of the object. Can be.

The electronic document conversion unit 160 converts the meta information of the electronic document for the word processor program into meta information of the electronic document, and converts the format object of the electronic document for the word processor program into objects of the electronic document.
