Abstract

A method and a device for visual management of metadata. An area with a plurality of data elements is visualized (504) to the user who determines (508) a route on the area, said route including a number of preferred elements belonging to the plurality of elements, which is detected (512). The preferred elements shall act as targets for a predefined metadata operation (514), e.g. change of a metadata attribute value.

Claims

1. A method for directing a metadata operation at a number of electronically stored data elements in an electronic device having the steps of

visualizing an area with a number of data elements on a display device to a user (504),

obtaining control information about a user-defined route between user-defined start and end points on the visualized area comprising said number of data elements (508),

specifying based on the route such data elements belonging to said number of data elements over which the route passed (512), and

performing the metadata operation on said specified data elements (514).

2. The method of claim 1, further having the step of visualizing a cursor to the user for route definition (506).

3. The method of claim 1, further having the step of visualizing the route (510).

4. The method of claim 3, wherein said route is visualized by a continuous or dotted line between the start and end points.

5. The method of claim 3, wherein said route is visualized by highlighting the specified elements.

6. The method of claim 1, further having the step of determining a certain metadata attribute (520) based on user input.

7. The method of claim 6, further having the step of determining a certain value for the metadata attribute (522).

8. The method of claim 6, wherein the metadata operation incorporates assigning the metadata attribute to the specified data elements.

9. The method of claim 1, wherein the control information is obtained via a keyboard, a mouse, a joystick, a control pen, a track ball, a touch pad, or a touch screen.

10. The method of claim 1, wherein a control device button press or release determines the start or end point of the route.

11. The method of claim 1, wherein the user-defined route comprises a number of start and end point pairs, each having a continuous portion between said start and end points.

12. An electronic device comprising

data output means (606) for visualizing an area with a number of data elements,

data input means (608) for receiving control information from a user, and

processing means (602) configured to determine based on the control information a user-defined route between user-defined start and end points on the visualized area comprising said number of data elements and to specify based on the route such data elements belonging to said number of data elements over which the determined route passed, whereupon said device is further configured to perform a metadata operation on said specified data elements.

13. The device of claim 12, further comprising memory means (604) for storing said data elements (610) or configuration information (612) for the processing means.

14. The device of claim 12, configured to visualize a cursor to the user for route definition.

15. The device of claim 12, configured to visualize the route.

16. The device of claim 15, configured to visualize the route by a continuous or dotted line between the start and end points.

17. The device of claim 15, configured to visualize the route by highlighting the specified elements.

18. The device of claim 12, configured to determine a certain metadata attribute based on user input.

19. The device of claim 18, further configured to determine a certain value for the metadata attribute.

20. The device of claim 18, configured to assign the metadata attribute to the specified data elements in the metadata operation.

21. The device of claim 18, configured to visualize a plurality of data elements to the user, to receive information about a user selection of one or more data elements belonging to the plurality, and to resolve the metadata attributes associated with the selected elements in order to carry out the determination.

22. The device of claim 12, configured to obtain control information inputted via a keyboard, a mouse, a joystick, a control pen, a track ball, a touch pad, or a touch screen.

23. The device of claim 12, wherein said data input means (608) comprises a keyboard, a mouse, a joystick, a control pen, a track ball, a touch pad, or a touch screen.

24. The device of claim 12, configured to determine the start or endpoint of the route based on a press or release of a control device button or a pressure sensitive surface.

25. The device of claim 12, configured to determine intermediate points of the route based on control device movement represented by said control information.

26. The device of claim 12, wherein said data input means (608) comprises an optical or a capacitive sensor.

27. The device of claim 12, configured to determine the route as a number of start and end point pairs, each having a continuous portion between said start and end points.

28. The device of claim 12, wherein said data output means (606) comprises a display or a projector.

29. The device of claim 12 that is a desktop computer, a laptop computer, a PDA (Personal Digital Assistant), or a mobile terminal.

30. A computer program comprising code means (612) for directing a metadata operation at a number of electronically stored data elements, said code means (612) adapted to, when the program is run on a computer device, visualize an area with a number of data elements on a display device to a user, to obtain control information about a user-defined route between user-defined start and end points on the visualized area comprising said number of data elements, to specify on the basis of the route such data elements belonging to said number of data elements over which the route passed, and finally to perform the metadata operation on said specified data elements.

31. A carrier medium having a computer program recorded thereon, the computer program comprising code means adapted to, when the program is run on a computer device, visualize an area with a number of data elements on a display device to a user, to obtain control information about a user-defined route between user-defined start and end points on the visualized area comprising said number of data elements, to specify on the basis of the route such data elements belonging to said number of data elements over which the route passed, and to perform a metadata operation on said specified data elements.

32. The carrier medium of claim 31 that is a memory card, a magnetic disk, or a cd-rom.
