Apparatus for supporting cooperation for joint editing of electronic document, and method of operating the same

A method of operating an apparatus for supporting cooperation for joint editing of an electronic document, the method comprising:

• when a request for an access to an original electronic document that is a cooperation target is received from a client terminal of a first user connected through a network, converting the original electronic document into a markup language-based document and storing the markup language-based document in a memory, and transmitting the markup language-based document to the client terminal of the first user;
• receiving one or more editing commands for the markup language-based document from the client terminal of the first user;
• producing a first document by reflecting the one or more editing commands to the markup language-based document stored in the memory;
• when a request for participation in cooperation for joint editing the electronic document is received from a client terminal of a second user connected through the network, transmitting the first document to the client terminal of the second user in response to the request for the participation in the cooperation;
• receiving a request for transmission of first commands from the client terminal of the second user after transmitting the first document, wherein the first commands are editing commands further received from the client terminal of the first user while the first document is transmitted to the client terminal of the second user, in addition to the one or more editing commands;
• determining whether there exist the first commands received from the client terminal of the first user while the first document is transmitted to the client terminal of the second user, in response to the request for the transmission of the first commands;
• and
• transmitting the first commands to the client terminal of the second user when it is determined that there exist the first commands received from the client terminal of the first user while the first document is transmitted to the client terminal of the second user.

A non-transitory computer readable recoding medium in which a program for executing a method of operating an apparatus for supporting cooperation for joint editing of an electronic document is recorded, the method comprising:

• when a request for an access to an original electronic document that is a cooperation target is received from a client terminal of a first user connected through a network, converting the original electronic document into a markup language-based document and storing the markup language-based document in a memory, and transmitting the markup language-based document to the client terminal of the first user;
• receiving one or more editing commands for the markup language-based document from the client terminal of the first user;
• producing a first document by reflecting the one or more editing commands to the markup language-based document stored in the memory;
• when a request for participation in cooperation for joint editing the electronic document is received from a client terminal of a second user connected through the network, transmitting the first document to the client terminal of the second user in response to the request for the participation in the cooperation;
• receiving a request for transmission of first commands from the client terminal of the second user after transmitting the first document, wherein the first commands are editing commands further received from the client terminal of the first user while the first document is transmitted to the client terminal of the second user, in addition to the one or more editing commands;
• determining whether there exist the first commands received from the client terminal of the first user while the first document is transmitted to the client terminal of the second user, in response to the request for the transmission of the first commands;
• and
• transmitting the first commands to the client terminal of the second user when it is determined that there exist the first commands received from the client terminal of the first user while the first document is transmitted to the client terminal of the second user.
