Abstract: A document cooperation supporting apparatus for supporting a simultaneous edit of a document according to an exemplary embodiment of the present invention, and an operating method thereof sequentially transmit edit commands to each of the client terminals based on a reception sequence of the edit commands when the simultaneously generated edit commands are received from the plurality of client terminals, and performs an operational transformation on edit commands having later reception sequences to provide a cooperation environment enabling users to simultaneously edit the document.

Abstract: An apparatus and a method of verifying a simultaneous edit match for a markup language-based document according to the present invention simultaneously apply a predetermined edit command set to a markup language-based document through simultaneous edit sessions, compare tags of the markup language-based documents, which are completely edited in respective edit sessions, and determine whether the tags of both documents are matched to each other, to assist a developer to determine whether a currently operated simultaneous edit support algorithm of a document normally supports a simultaneous edit according to edit commands included in the corresponding edit command set.

Abstract: The present invention provides a web-based electronic document service apparatus, which is capable of authenticating the edit of a document, and an operating method thereof, in which when a predetermined authentication token is randomly issued and transmitted to a client terminal accessing for editing an electronic document based on a web, and then an editing command and an authentication token corresponding to the editing command are received from the client terminal, it is determined whether the received authentication token corresponds to the previously issued authentication token, so that it is possible to confirm whether the editing command received from the client terminal is the editing command generated by the true user, thereby providing a security mechanism.

Abstract: Disclosed are a document collaboration apparatus for supporting simultaneous editing of styles of objects and an operating method thereof in which when an access request for simultaneous editing of one electronic document is received from a plurality of users, the electronic document is converted into a markup language based document and provided to the respective users and thereafter, the markup language based document to which the same style editing is reflected is supported to be continuously maintained among the plurality of users to enable the plurality of users to commonly edit the document.

Abstract: An apparatus and a method of supporting cooperation for joint editing of an electronic document according to an exemplary embodiment of the present invention transmit a markup language-based document, to which an editing contents generated up to present by a first user are reflected, to a client terminal of a second user when the second user participates in cooperation for an electronic document while the first user is editing the electronic document converted into the markup language-based document, thereby supporting the first user and the second user to simultaneously edit the same markup language-based document.
