Abstract

A method and a system for managing metadata of a numerical stock map are provided to smoothly input the metadata whether or not production of the numerical stock map is completed by inputting the metadata when the metadata needs to be inputted though the numerical stock map is being produced. A method for managing metadata of a numerical stock map includes the following several steps. A metadata management system displays a metadata management screen when the numerical stock map is selected(S201,S203). If there does not exist the metadata including data element values on the selected numerical stock map, and attached files which are a quality management report and an attribute information explanation document, the metadata management system enables a user to input the metadata(S205,S207). If there exists the metadata, the metadata management system edits the metadata to correspond to inputted signals(S223-S227). The system manages update information among the data element values including update date, an update time, an update cause, an update process and an update person(S231). The system links the inputted and edited metadata with the selected numerical stock map, and stores the linked data(S221).

Referring to FIGS. 1, 2, and 4A to 4C, in operation S201, the control unit 103 inputs a selection signal for a numerical clinical picture to which metadata is to be input from the numerical clinical picture stored in the numerical clinical picture DB 113. Upon reception from the device, in step S203, the controller 103 displays the metadata management screen on the screen of the display device. Subsequently, in step S205, the controller 103 determines whether metadata corresponding to the numerical clinical level selected in step S201 exists in the metadata DB 115.

If the metadata corresponding to the numerical clinical level selected in step S201 exists in the metadata DB 115 in step S205, the controller 103 proceeds to step S223 and the edit control module 105 edits the metadata. do. Detailed description of the editing of the metadata will be described later.

On the contrary, if the metadata corresponding to the numerical clinical value selected in step S201 does not exist in the metadata DB 115 in step S205, the control unit 103 proceeds to step S207 and the edit control module 105 returns to the numerical clinical picture. Perform metadata entry process for At this time, since there is no metadata in the metadata DB 115, the metadata management screen in which the metadata item value is not described in the text field as shown by reference numeral 411 in FIGS. 4A to 4C is displayed on the screen of the display device. .

Subsequently, in step S207, the controller 103 proceeds to step S209 if the signal received from the input device is a signal for inputting metadata, and proceeds to step S233 if it is not a signal for inputting metadata.

In step S207, when the metadata item value is input to the text field indicated by reference numeral 411, the control unit 103 detects the input of the metadata item value as a signal for inputting the metadata and proceeds to step S209. However, in the embodiment of the present invention, the metadata input is determined by the input of the metadata item value, but the metadata input may be determined by the addition of the attachment file.

Subsequently, in step S209, the edit control module 105 receives the item value for the metadata item received from the input device in step S207, and proceeds to step S211. When the metadata item value is input in step S209, a database having a form as shown in Table 2 below is formed. If the control unit 103 receives a signal for adding an attachment from the input device in step S211, the attachment control module 107 proceeds to step S213. In step S213, the attachment control module 107 displays an attachment file adding screen indicating an attachment file list for the numerical clinical degree stored in the storage unit 109 (not shown).

This is a screen example of the quality / update / distribution / pharmaceutical information tab activated. Subsequently, when the control unit 103 receives a signal for editing metadata from the input device in step S225, the control unit 103 proceeds to step S227.

In step S227, the edit control module 105 edits the metadata based on the signal input from the input device. In addition, when a signal is generated at the default button 401 of FIGS. 4A to 4C, the edit control module 105 is set to match the map characteristics of the numerical clinical image and stored in the storage unit 109 (hereinafter, referred to as a metadata item value). Change the displayed metadata on the metadata management screen. In addition, when a signal occurs at the delete button 405, the edit control module 105 deletes the item value of the metadata changed to the default value.

In addition, when the attachment control module 107 selects one attachment file from two attachment files displayed in the attachment file field 413 of FIG. 4C, the delete button corresponding to reference numeral 417 is activated to delete the selected attachment file. have. In addition, when a signal occurs in the add button 415, an attachment may be added.

Subsequently, when the control unit 103 detects the editing completion of the metadata in step S229, the editing control module 105 generates an update history of the edited metadata item value and provides it to the control unit 103 in step S231. In addition, the controller 103 may display the update history in the update information field indicated by reference numeral 411. In step S221, the controller 103 stores the generated update history in the metadata DB 115 and stores the edited metadata in the metadata DB 115 in the form of a file. On the contrary, if the editing completion of the metadata is not detected, the control unit 103 returns to step S227 to continuously edit the metadata.

In step S233, when the controller 103 detects that the signal received from the input device is a signal for editing an item of metadata (that is, a signal generated by a code management button 407), the controller 103 proceeds to step S235. Proceed. The edit control module 105 edits the code information for the metadata item based on the signal received from the input device. Subsequently, in step S237, the edit control module 105 determines whether editing of the code information on the metadata item is completed, and when editing of the code information is completed, the process proceeds to step S221 and the edited code information is stored in the storage unit 109. Save it. At this time, the code information of the edited metadata item is updated in the database of Table 1. In addition, when editing of the code information is not completed in the determination result of the edit control module 105 in step S237, the control unit 103 returns to step S235 to re-edit the code information for the metadata item.

On the contrary, when the control unit 103 detects that the signal received from the input device is a signal generated in the close button of reference number 409 in step S233, the control unit 103 recognizes the signal for ending the metadata management screen and the metadata management screen.
