Abstract: A non-transitory computer-readable storage medium includes a user interface configured to display data when a computer program stored in the non-transitory computer-readable storage medium is executed by one or more processors of a computing device; a version tree layer included in the user interface and configured to display a version tree including a main tree composed of one or more versions and a subtree composed of one or more subversions; and a data display layer included in the user interface and configured to display data corresponding to a selectively inputted subversion in response to a selective input for at least one subversion included in the version tree.

Abstract: A method for providing a function to review visual contents by a server is provided. The method includes (a) providing a visual content upload area to a first terminal and receiving an upload request including identification information of previously produced visual content from the first terminal; (b) receiving a click-input for the visual content of the first terminal or a second terminal invited by the first terminal and providing a review interface to the first terminal or the second terminal; and (c) collecting comment information input by the first terminal or the second terminal through the review interface and storing the comment information by matching with identification information of the visual content, in which the review interface includes a visual content display area, an annotation area and a comment area including a function of visually displaying a portion to be reviewed and evaluated in the visual content display area.

Abstract: A method for providing a platform to manage produced visual contents includes (a) providing a main interface for a project by a server to a first terminal when the first terminal requests to generate the project for managing visual contents; (b) transmitting a project invitation message by the server to a second terminal when the first terminal inputs a project member request including identification information of the second terminal, and providing the main interface to the second terminal; (c) providing an upload area by the server, uploading visual contents in relation to the project by the first or the second terminal to the upload area, and providing a review interface displaying the visual contents by the server; and (d) displaying a text or a drawing image for evaluation or review overlapped with the visual contents by an input of the first or the second terminal through the review interface.

Abstract: A method for providing a shared link of visual content performed by a server includes (a) receiving an upload request of a visual content from first and second terminals in response to project members through an upload area in main interface; (b) providing a shared link access information input area and an authority setting area to the first terminal or the second terminal; (c) generating a shared link in which the uploaded visual content is displayed based on the input shared link access information, and providing access information of the shared link to a third terminal; and (d) grasping whether the third terminal is a previously registered terminal based on user identification information input from the third terminal when the third terminal is accessed through the shared link, and providing a sharing interface, which is preset according to whether the registration is performed, to the third terminal.

Abstract: A method for providing a chat function for management of visual contents performed by a server is provided. The method includes (a) receiving a project creation request including project identification information from a first terminal, and providing a main interface and a review interface to the first terminal and a second terminal accessed according to a project member request input of the first terminal; (b) providing a chat area when receiving an input for a chat menu in the main interface or review interface from the first terminal or the second terminal; and (c) managing chat messages differently for each project by matching chat information input through the chat area and comment information input through the review interface with the project identification information.
