Description

Electronic document creation and conversion method of cloud-based electronic document platform {METHOD FOR EDITING AND CONVERTING ELECTRONIC DOCUMENT ON CLOUD-BASED ELECTRONIC DOCUMENT PLATFORM}

The present invention relates to an electronic document conversion method of a cloud-based electronic document platform, and more particularly, to create an electronic document in a cloud-based electronic document platform that provides a collaborative environment so that a plurality of users can create electronic documents online , It relates to a method of converting into an electronic document format according to HTML standards.

In recent years, as a high-speed Internet environment has been established and a wireless Internet environment allowing access to the Internet anytime, anywhere has been established, electronic document-related services are provided to electronic terminal devices, which are client terminals, through remote servers, so that users can access electronic documents. An online-based document creation service has emerged that allows users to read, create, and edit electronic documents anytime, anywhere, even without installing a predetermined electronic document-related program in a terminal device.

This online-based document creation service supports various client terminals to view, write, and edit electronic documents through browsers installed in the client terminals after accessing the document preparation service providing server. It is mainly used by companies or organizations in that it supports simultaneous collaboration on electronic documents in real time.

In addition, the online-based document creation service allows users to view, create, and edit electronic documents through a browser installed in a client terminal, as long as they can access the Internet without the need to install a predetermined electronic document preparation program in the client terminal. Since the user's mobility can be guaranteed, the number of individual users is gradually increasing.

However, the so-called "Araeah Hangul" or "HWP document" of Hangeul and computer companies, which are widely used mainly in government offices and schools in Korea, has some problems because it is used in a cloud-based electronic document platform.

Hangul and computer companies support the document format of Hangul 97 free of charge based on the value set of openness and standardization of document format, and the XML format of Hangul 2002-2010 document is also open to HWPML (Hangul Word Processor Markup Language). It is known to be doing The HWPML format file is written in a markup language in a tag format and is stored as a text file. The HWPML specification was established as a Korean Industrial Standard (KS X 6101:2 011) under the name OWP-ML. It is also known that Hancom Office supports PDF/A-1, the standard format for long-term preservation of records, and import and save of ODF and OOXML file formats, which are ISO international document formats.

On the other hand, the contents stored in the HWP file document file include not only the contents and character decoration information of the document actually input by the user, but also information about the font at the time of editing the document, and settings affecting typesetting (paper type, margin information) Also includes

By the way, the HWP file document uses zlib of zlib.org to minimize the size of the file. zlib is a software whose source is open on the web. The structure of Hangul Document File 5.0 is based on the Windows compound file, and the character code is based on the ISO-10646 standard, and most of the character information is Unicode (UTF-16LE). ) format and stored. However, even if the zlib source known to be open is used, there is a problem in that the document structure of the HWP file cannot be completely edited and saved so as not to be “broken”.

In this regard, as a preceding study for HWP conversion, there is snapshot-based computation offloading. Snapshot-based computation offloading uses snapshot technology to save the state of a web application in the form of another web application consisting of HTML, CSS, and JavaScript. At this time, the web application is a conversion technology that parses the HTML document to create a DOM tree, displays it on the screen, and has the state information of the current screen.

There was also a study on an algorithm for extracting the text to systematically manage the document by extracting only the correct text area within the HTML document.

As such, a request for a technology for appropriately converting an HWP document into an HTML document has been continuously raised.

The present invention has been conceived in response to the above requests, and creates electronic documents in a cloud-based electronic document platform that provides a collaborative environment so that a plurality of users can create electronic documents online, and electronic documents comply with HTML standard rules. Its purpose is to provide a method of converting to a document format.

In order to achieve the above object, a method for preparing and converting an electronic document of a cloud-based electronic document platform according to one aspect includes selecting and opening an editing target file in a terminal connected to the cloud-based electronic document platform; separating text information and format information from the selected file to be edited; and performing table processing based on the text information.

At this time, the step of performing the table processing may further include processing a paragraph consisting only of text.

In addition, the performing of the table processing may further include extracting text from a table included in the editing target file.

In addition, the performing of the table processing may further include processing a table included in the editing target file as an image.

2 is a block diagram showing a cloud-based electronic document platform according to an example;
3 is a flowchart illustrating a method of creating an electronic document in a cloud-based electronic document platform according to another embodiment.

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

1 is a flowchart illustrating a flow of a method of creating and converting an electronic document of a cloud-based electronic document platform according to an example.

As shown in FIG. 1, the electronic document creation and conversion method of the cloud-based electronic document platform according to an example includes a file selection step (S100), a text information and format information separation step (S110), and a table processing step (S120). It is done by

In the file selection step (S100), a file to be edited is selected and opened in a terminal connected to a cloud-based electronic document platform.

In the step of separating text information and format information (S110), text information and format information are separated from the selected file to be edited.

In the table processing step (S120), table processing is performed on the entire corresponding electronic document based on the separated text information.

When the electronic document is converted through this process, two HTML files are generated in the cloud-based electronic document platform according to this embodiment.

One is a CSS file for format management and the other is a text HTML file for expressing document contents.

The reason why formatting information is stored separately in CSS is to simplify the part where repeated formatting in the conversion process is duplicated in the HTML code.

Since the range of conversion is limited to letters and tables, the format used for this is mainly a repetition of a certain pattern. Therefore, in order to efficiently process this, a method of specifying and saving the pattern of the format in a certain format in the CSS file and inserting the pattern is used instead of repeatedly inserting the repetitive format into the HTML conversion file.

By using this method, it is possible to improve file size and conversion speed by reducing repeated attributes.

Meanwhile, the table processing performed in the table processing step (S30) further performs at least three sub-processing steps.

First, a step of processing a paragraph consisting only of text may be further performed.

Second, a step of extracting text from a table included in a file to be edited may be further performed.

Since tables that are not text-processed are entities, it is necessary to process these tables separately. In particular, there is a problem in that the exact location coordinates are not specified for tables that are not text-processed. Therefore, since the location at the time of saving is not specified in a specific location like letters, when the computer created and the other computer or environment are viewed on a different monitor, it is not preserved in the location intended by the author and placed in a different location.

In order to solve this problem, check whether the size of the page, the paragraph, and the location of the text-processed table collide with the location of the non-text-processed table.

By using the position and size of the text-free table, the text-free table is placed in a position that does not collide with other elements, and the location is specified to use the specified location when converting to HTML.

Define PageRecordChar as a class that stores and processes information on actual character values of HWP documents, and PageRecordType as an enumeration class that distinguishes paragraphs, tables (lettered tables), and rectangles (non-lettered tables), respectively. can be configured.

Since texted tables are processed in the same way as paragraphs, they are processed through this routine, and non-lettered tables are processed through page boundaries and other characters in PageSplit by using the information on the page dividing standard of PageSize, which handles the page size. After checking whether there is a collision between the characters, it finds a table that has not been processed.

In TablePosition, which received the table composed of this information as a parameter, process the part about the table that is not text-processed. At this time, since the characters are not processed, there is a possibility of collision between the characters and the table, so whether or not there is a collision with paragraphs is used to set the position of the table to a position where collision does not occur.

According to the type of processed information, paragraphs and text-processed table information are immediately stored in PageRecord.

Thirdly, a step of processing a table included in an editing target file as an image may be further performed.

Tables that are not text processed receive information from TableRecord and save it to PageRecord. PageRecord is the basic unit that composes Page.

By doing this, it is possible to store information on all characters, paragraphs, tables, and forms stored in a page for each page of the HWP document.

In the present invention, the text in the HWP document is created as an HTML document using the PageRecord stored in the Page, so that the text HTML document is finally completed.

2 is a block diagram illustrating a cloud-based electronic document platform according to an example.

Referring to FIG. 2 , the cloud-based electronic document platform 110 includes a document storage 111, a document providing unit 112, a linked document list providing unit 113, and a linked document providing unit 114.

In the document storage 111, a plurality of electronic documents and at least one linked electronic document designated in advance as being linked as a related electronic document for each of the plurality of electronic documents (the at least one linked electronic document is Information about electronic documents included in the plurality of electronic documents) is stored in correspondence with each other.

At this time, the plurality of electronic documents stored in the document storage 111 refer to documents having a format of a general electronic document file that can be driven by an installable document creation program having an extension such as "hwp" or "docx".

When a request for access to a first electronic document among the plurality of electronic documents is received from a client terminal (not shown) of a first user connected to a network, the document providing unit 112 stores the first electronic document from the document storage 111. After extracting 1 electronic document, the first electronic document is converted into a first markup document configured in a markup language-based format, and the first markup document is transmitted to the client terminal of the first user.

Here, a document composed of a markup language-based format means a document composed of a markup language such as HTML (Hypertext Markup Language) or XML (eXtensible Markup Language) that can be viewed through a browser installed in a client terminal.

The linked document list providing unit 113 checks information on at least one first linked electronic document designated as being linked to the first electronic document from the document storage 111 and then returns the at least one first linked electronic document to the at least one first linked electronic document. A document list is generated and transmitted to the client terminal of the first user.

When a request for access to a second connected electronic document among the at least one first connected electronic document provided to the document list is received from the client terminal of the first user, the connected document providing unit 114 stores the document storage 111 in the connection document. After extracting the second linked electronic document, the second linked electronic document is converted into a second markup document configured in a markup language-based format, and the second markup document is transmitted to the client terminal of the first user.

After being added, when a command to delete a connection to the second electronic document is received from the client terminal of the first user, the at least one first connected electronic document stored in the document storage 111 in correspondence with the first electronic document Among the document information, information on the second electronic document is immediately deleted.

The second linked document deletion processing unit 117 determines that information on the second electronic document corresponds to information on the at least one first linked electronic document stored in the document storage 111 in correspondence with the first electronic document. After being added, if a command to delete the connection to the second electronic document linked to the first electronic document is received from client terminals of users other than the first user, the first electronic document is stored in the document storage 111. From the client terminals of a predetermined number of users or more within a predetermined time from the time when the information on the second electronic document is added to the information on the at least one first connected electronic document stored in correspondence thereto, 2 The second electronic document among the information on the at least one first linked electronic document stored in the document storage 111 in correspondence with the first electronic document only when it is determined that a command to delete the connection to the electronic document is received. Delete information about a document.

In addition, the cloud-based electronic document platform 110 may further include an editing command receiver 118 , a document editing performer 119 , and an edited document storage unit 120 .

When the editing command receiving unit 118 receives at least one editing command for the first markup document from the client terminal of the first user after the first markup document is transmitted to the client terminal of the first user, the first markup document is transmitted to the client terminal of the first user. At least one editing command is received from a client terminal of one user.

The document editing execution unit 119 performs editing by reflecting the at least one editing command on the first markup document stored in the memory.

When an editing completion command for the first markup document is received from the client terminal of the first user, the edited document storage unit 120 transfers the edited first markup document stored in the memory to the first markup document. The first electronic document is converted into the same document format as the electronic document and stored in the document storage 111 in place of the first electronic document.

In this case, when the first markup document is received, the client terminal of the first user renders the first markup document through the first browser installed in the client terminal of the first user and displays the first markup document on the screen. 1 Edit the first markup document displayed on the screen according to the at least one editing command input from the user, and transmit the at least one editing command to the online document preparation service device 110 can

At this time, in the document storage 111, edit history information for each of the plurality of electronic documents may be additionally stored in correspondence with each of the plurality of electronic documents.

Here, the editing history information includes a name of a user who edited each of the plurality of electronic documents and information about a completion time of editing.

At this time, the connection document providing unit 114 receives a request for access to the second connection electronic document among the at least one first connection electronic document provided to the document list from the client terminal of the first user, the second connection document providing unit 114 . The electronic document is converted into the second markup document configured in a markup language-based format and the second markup document is transmitted to the client terminal of the first user and stored in correspondence with the second connected electronic document Editing history information may be transmitted to the client terminal of the first user.

In addition, when an editing completion command for the first markup document is received from the client terminal of the first user, the edited document storage unit 120 retrieves the edited first markup document stored in the memory. The first electronic document is converted into the same document format as the first electronic document and stored in the document storage 111 in place of the first electronic document, and at the same time, the document storage 111 ), editing history information stored in correspondence to the first electronic document may be updated.

In addition, the cloud-based electronic document platform 110 may further include an electronic document download processor 121 .

When the electronic document download processing unit 121 receives a download command for the first markup document from the client terminal of the first user after the first markup document is transmitted to the client terminal of the first user, the first markup document is transmitted to the client terminal of the first user. After the file for the at least one first linked electronic document is inserted as a file object on the electronic document, the file for the first electronic document in which the at least one first linked electronic document is inserted as a file object is inserted. It can be transmitted to the client terminal of the first user.

Hereinafter, the operation of the cloud-based electronic document platform 110 will be described in detail by way of example.

First, in the document storage 111, as shown in Table 1 below, a plurality of electronic documents and at least one linked electronic document designated in advance as being linked to a related electronic document for each of the plurality of electronic documents. Information on and editing history information on each of the plurality of electronic documents may be stored in correspondence with each other.

At this time, when an access request for “electronic document 1” among the plurality of electronic documents is received from the client terminal of the first user, the document providing unit 112 extracts “electronic document 1” from the document storage 111 and After converting the "electronic document 1" into a "markup document 1" configured in a markup language-based format such as HTML, the converted "markup document 1" is stored in the memory of the online document creation service device 110 itself. and may transmit the converted “Markup Document 1” to the client terminal of the first user.

At this time, the linked document list providing unit 113 checks information on “electronic document 3, electronic document 4, and electronic document 5” designated as being connected to the “electronic document 1” from the document storage 111, and then “electronic document 1”. Document lists for “Document 3, Electronic Document 4, and Electronic Document 5” may be generated and the document lists for “Electronic Document 3, Electronic Document 4, and Electronic Document 5” may be transmitted to the client terminal of the first user.

In this way, when the document lists for “electronic document 1”, “electronic document 3, electronic document 4, and electronic document 5” are transmitted to the client terminal of the first user, the client terminal of the first user receives the first user's client terminal. The “markup document 1” may be rendered and displayed on the screen through the first browser installed in the .

At the same time, the client terminal of the first user displays document lists for "electronic document 3, electronic document 4, and electronic document 5" on the screen, so that "electronic document 3, electronic document 4, and electronic document 5" are displayed as the "electronic document 3, electronic document 4, and electronic document 5". It is related to "electronic document 1" and can indicate that it is a linked document.

In this way, when the document list for “Markup Document 1”, “Electronic Document 3, Electronic Document 4, and Electronic Document 5” is displayed on the screen through the client terminal of the first user, the first user through the client terminal Editing of the "Markup Document 1" may be performed on the first browser, and at this time, when at least one editing command is input from the first user, the client terminal of the first user responds to the at least one editing command. Accordingly, the "markup document 1" displayed on the screen may be edited, and the at least one editing command may be transmitted to the online document preparation service device 110 .

At this time, when the at least one editing command for the "markup document 1" is transmitted from the client terminal of the first user, the editing command receiving unit 118 receives the at least one editing command from the client terminal of the first user. and the document editing execution unit 119 may perform editing on the “Markup Document 1” by reflecting the at least one editing command to the “Markup Document 1” stored in the memory. there is.

And, as the first user completes editing of the “Markup Document 1”, the first user performs an action such as pressing a save button for the “Markup Document 1” through the client terminal, thereby causing the “Markup Document 1” to be edited. When an editing completion command for “Markup Document 1” is transmitted to the online document writing service device 110, the edited document storage unit 120 stores the edited “Markup Document 1” stored in the memory. The “Electronic Document 1” is converted into the same document format as the “Electronic Document 1” and stored in the document storage 111 in place of the “Electronic Document 1”. Editing history information stored in correspondence to the "electronic document 1" may be updated on (111).

Through this, the first user accesses the online document writing service device 110 and downloads the "electronic document 1" stored in the document storage 111 from a remote location through the first browser installed in his or her client terminal. Can edit and write.

In this way, when the first user edits the "markup document 1" through his/her client terminal, the "electronic document 3, electronic document 4, and electronic document 5" linked to the "markup document 1" ", the first user sees the list of documents for "Electronic Document 3, Electronic Document 4, and Electronic Document 5" displayed through the client terminal of the first user, An access request may be transmitted to the online document preparation service device 110 .

If the online document preparation service device 110 receives a request for access to “electronic document 3” among “electronic document 3, electronic document 4, and electronic document 5” from the client terminal of the first user, the connection document The study 114 extracts "electronic document 3" from the document storage 111 and converts the "electronic document 3" into a "markup document 3" configured in a markup language-based format to obtain the "markup document 3" is transmitted to the client terminal of the first user, and at the same time, "Editing user: user 1, editing completion time: February 3, 2015, 1:00," which is the editing history information stored in correspondence with the "electronic document 3" is provided. It can be transmitted to the client terminal of 1 user.

Through this, the first user edits the "Markup Document 1", and the "Electronic Document 3", which is a linked document that the first user wants to view, through the first browser of the client terminal of the "Markup Document 3". In this way, the first user can open the "electronic document 3", which is a linked document related to the "electronic document 1".

The "Markup document 1" is transmitted to the client terminal of the first user, and while the first user is editing the "Markup document 1", the "Markup document 1" is stored in the document storage 111 When designating a specific electronic document among a plurality of existing electronic documents as a linked document, the first user connects to the specific electronic document he/she intends to designate as a linked document for the "markup document 1" through the client terminal. A command may be transmitted to the online document preparation service device 110 .

For example, a document connection command for a first user to connect to "electronic document 2" among a plurality of electronic documents stored in the document storage 111 for the "markup document 1" is created online through a client terminal. In the case of transmission to the service device 110, the connection document adding unit 115 stores information about the connected electronic document corresponding to the "electronic document 1" in the document storage 111, such as "electronic document 3, electronic document Information on the “electronic document 2” may be added to “document 4, electronic document 5”.

In this way, the first user easily connects another electronic document he/she wants to link to the corresponding electronic document while editing the electronic document, so that when editing the corresponding electronic document again later, the first user connects the electronic document to the corresponding electronic document. Linked documents may be provided together from the online document preparation service device 110 .

At this time, the information about “electronic document 3, electronic document 4, and electronic document 5”, which is information about connected electronic documents stored in the document storage 111 corresponding to the “electronic document 1” by the first user, is stored in the “electronic document 111”. If a command to delete the connection to the “electronic document 2” is received from the client terminal of the first user after the information on “document 2” is added, the first linked document deletion processing unit 116 stores the information on the document storage 111. Information on “Electronic Document 2” can be immediately deleted from among the information on connected electronic documents “Electronic Document 2, Electronic Document 3, Electronic Document 4, Electronic Document 5” stored in correspondence with “Electronic Document 1”. .

However, information about the connected electronic documents stored in the document storage 111 corresponding to the "electronic document 1" by the first user, such as "electronic document 3, electronic document 4, and electronic document 5", the "electronic document 1" After information on “Document 2” is added, if a command to delete the connection to “Electronic Document 2” connected to “Electronic Document 1” is received from client terminals of users other than the first user, the second connection The document deletion processing unit 117 stores information about connected electronic documents, such as “electronic document 3, electronic document 4, and electronic document 5” stored in correspondence with the “electronic document 1” in the document storage 111, in the “electronic document 1”. Document storage 111 only when it is confirmed that the command to delete the connection to the “electronic document 2” has been received from the client terminals of a predetermined number of users or more within a predetermined time from the time when the information on “document 2” is added. ) to delete the information on the “Electronic Document 2” among the information on the linked electronic documents “Electronic Document 2, Electronic Document 3, Electronic Document 4, and Electronic Document 5” stored in correspondence with the “Electronic Document 1” can

For example, if the selected time is "24 hours" and the selected number is "10", the second connection document deletion processing unit 117 corresponds to the "electronic document 1" in the document storage 111 "10" or more users within "24 hours" from the time when the information on "Electronic Document 2" is added to the information on the stored linked electronic documents "Electronic Document 3, Electronic Document 4, and Electronic Document 5" “Electronic document 2, electronic document 3, Among the information on the connected electronic documents, e.g., electronic document 4 and electronic document 5, the information on the "electronic document 2" may be deleted.

That is, when a user who designates a linked electronic document directly requests deletion of the linked electronic document, the first linked document deletion processing unit 116 immediately deletes the linked document because he/she is a user who has designated the linked electronic document. 2 When other users who do not designate the linked electronic document request deletion of the linked electronic document, the linked document deletion processor 117 deletes the linked electronic document at a specific time from the point in time when the linked electronic document is designated because the user is not the user who specified the linked electronic document. The deletion process may be performed only when more than a certain number of users request deletion of the corresponding linked electronic document within a specified number of days.

According to one embodiment of the present invention, after the "Markup Document 1" is transmitted to the client terminal of the first user, a download command from the client terminal of the first user to the client terminal for the "Markup Document 1" is received, the electronic document download processing unit 121 inserts the files for the connected electronic documents of "electronic document 3, electronic document 4, and electronic document 5" into the "electronic document 1" as a file object, and then The file for the "Electronic Document 1" in which "Electronic Document 3, Electronic Document 4, and Electronic Document 5" are inserted as file entities may be transmitted to the client terminal of the first user.

At this time, the electronic document download processing unit 121 is the application software currently being edited in the form of an OLE (Object Linking and Embedding) object, which is a function that directly pulls data such as pictures, tables, charts, and videos created in other application software. Insert the files for the linked electronic document called "Electronic Document 3, Electronic Document 4, and Electronic Document 5" on "Document 1", By inserting a file for "electronic document 1" in an embedding method instead of a linking method, when the first user downloads the file for "electronic document 1" and executes it through a client terminal, the file on "electronic document 1" It is possible to support loading of files for "electronic document 3, electronic document 4, and electronic document 5" embedded in .

3 is a flowchart illustrating a method of operating a cloud-based electronic document platform.

In step S210, a plurality of electronic documents and at least one linked electronic document designated in advance as being connected as a related electronic document for each of the plurality of electronic documents (the at least one linked electronic document is the plurality of electronic documents) A document repository is maintained in which information about electronic documents included among documents is stored in correspondence with each other.

In step S220, when a request for access to a first electronic document among the plurality of electronic documents is received from a client terminal of a first user connected to a network, the first electronic document is extracted from the document storage and then the first electronic document is stored. The document is converted into a first markup document configured in a markup language-based format, the first markup document is stored in a memory, and the first markup document is transmitted to a client terminal of the first user.

In step S230, after checking information on at least one first connected electronic document designated as being connected to the first electronic document from the document storage, a document list for the at least one first connected electronic document is generated. It is transmitted to the client terminal of the first user.
