Description

  The present invention relates to a metadata editing system, a metadata editing program, and a metadata editing method for editing metadata of content, and relates to a metadata editing system, a metadata editing program, and a metadata editing method for adding metadata to material content. It is related to effective technology.

  In companies such as broadcasting stations and production companies, when video / audio content is produced, the video / audio that is the material is collected first. The video / audio data used as the material is hereinafter referred to as material content. On the other hand, content such as a program to be produced by a broadcasting station or production production is hereinafter referred to as completed content. The completed content is created by combining one or more material contents and adding effects, that is, editing.

  The created completed content is stored in the archive system after being broadcast or used by another distribution provider. Since the amount of content stored in the archive system is enormous, when storing, the content ID and description information are associated with each other and registered in the database system. Thereby, it is possible to search at the time of taking out the content.

  In general, the description information is given a production date and time, the name of the producer, and the like in addition to the title of the content. However, in order to make it possible to perform advanced search in a further step, the video / audio is divided into somewhat fine time intervals, and each piece is explained based on the content of the video / audio content. May be included. The text data serving as the explanation information is hereinafter referred to as metadata. For example, it is conceivable that the metadata includes the name of an actor appearing in the video during the time interval, the state of the scenery, and the like.

Various techniques for assigning metadata to content and editing the attached metadata have been proposed. For example, JP 2006-325047 A (Patent Document 1) and JP 2004 2004 A A technique such as Japanese Patent No. -348553 (Patent Document 2) has been proposed.
JP 2006-325047 A JP 2004-348553 A

  However, it is said that the material content has more than 10 times the capacity of the completed content, and due to the work load of adding metadata, the metadata is actually given only to the completed content, and the metadata is added to the material content. Is rarely granted.

  As described above, the completed content is created by using the material content as editing material. An editing operator selects and edits material content that is most suitable for creating completed content from a large amount of material content. At this time, existing material content may be reused. However, since metadata is not given to the material content, there is a problem that the search by the database system cannot be used effectively when the material content is taken out, and work efficiency is poor.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a metadata editing system, a metadata editing program, and a metadata editing method that can reduce the effort of inputting metadata to material content as much as possible.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows.

  The metadata editing system according to the representative embodiment of the present invention is based on editing information indicating how the completed content is created by editing one or more material contents. The content content metadata and the accuracy representing the certainty of the metadata are generated.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

  According to the representative embodiment of the present invention, since the metadata of the material content can be generated without performing the work of adding the metadata to the material content, the database system is used when searching for the material content. It becomes possible to use the search by. Further, when creating another completed content based on the material content to which the metadata is added, it is possible to save the trouble of adding the metadata to the completed content. As a result, the efficiency of content editing can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

<Overview>
The metadata editing system according to an embodiment of the present invention does not need to perform an operation of assigning metadata to material content in an environment in which an operator inputs metadata to the created completed content. This is a system that automatically generates metadata of material content using metadata assigned to completed content.

  The metadata editing system according to the present embodiment includes a metadata management server that holds metadata of completed content and metadata of material content, and a metadata editing terminal for assigning metadata to the content. The The worker basically gives metadata to the completed content. Using the metadata assigned to the completed content, the metadata editing terminal automatically generates the metadata of the material content constituting the completed content.

  An EDL (Edit Decision List) is used as a method for automatically generating metadata of material content from completed content. The EDL includes information on how the material content is combined to generate the completed content. Based on this, the percentage of each material content used in the completed content in a certain time interval is calculated, and the accuracy is obtained based on that. The metadata of the material content is registered in the metadata management server together with the accuracy.

  Further, in the metadata editing terminal, the operator can input the metadata of the material content that has already been created on the GUI (Graphical User Interface) as metadata of the completed content. In this case, even if the accuracy of the material content is not 100% at that time, since the operator has transcribed as metadata of the completed content, the content represented by the metadata is displayed on the completed content. Will be. Therefore, it is determined that the metadata of the material content is correct, and the accuracy of the metadata of the material content is fixed to 100%.

  Further, in the metadata editing terminal, the operator can transfer the metadata of a certain time section of the completed content already input to another time section on the GUI and input it as metadata of the completed content. In this case, it is assumed that the same contents as the time section of the transfer source were displayed in the time section of the transfer destination. Even if the accuracy of the metadata of the material content constituting the completed content in the time section of the transfer source is not 100%, only one material content overlaps with the material content constituting the completed content in the time section of the transfer destination. If there is, it is determined that the metadata of the material content is correct, and the accuracy of the metadata of the material content is fixed to 100%.

<Embodiment>
Hereinafter, a metadata editing system according to an embodiment of the present invention will be described. FIG. 1 is a diagram illustrating a configuration example of a metadata editing system according to the present embodiment. The metadata editing system includes a metadata management server 100 and a metadata editing terminal 200, which are connected via a network 300. A configuration having a plurality of metadata editing terminals 200 may also be used.

  Using the metadata editing terminal 200, the worker inputs metadata of the completed content while playing back the completed content and checking the content. The input metadata is registered in the metadata management server 100. At that time, the metadata editing terminal 200 uses the EDL, which is editing information indicating how the completed content is produced by combining the material content, and uses the metadata of the material content constituting the completed content. Generate and register in the metadata management server 100. As a result, metadata assigned to the material content is stored.

The metadata management server 100 includes a metadata update unit 110, a metadata search unit 120,
The computer has a metadata DB unit 130 and manages metadata of completed content and material content. The functions of the metadata update unit 110 and the metadata search unit 120 are realized by software.

  The metadata DB unit 130 is a database that manages an ID that uniquely identifies completed content and material content and metadata that is description information of the content in association with each other. The metadata search unit 120 executes a search for the metadata DB unit 130 based on the text as a keyword, and acquires metadata including the keyword and IDs of completed content and material content corresponding to the metadata. The metadata update unit 110 updates the metadata DB unit 130 in response to an instruction to update metadata from the outside.

  When performing a search based on a keyword for completed content or material content using the metadata editing terminal 200, the metadata search unit 120 executes a search for the metadata DB unit 130. Also, when updating the metadata of the completed content using the metadata editing terminal 200, the metadata search unit 120 performs a search on the metadata DB unit 130 in order to acquire the current metadata. When the metadata editing terminal 200 edits the metadata of the completed content and stores the modified metadata, the metadata update unit 110 receives an instruction from the metadata editing terminal 200 and changes the metadata DB unit 130. Update.

  The metadata editing terminal 200 includes an editing GUI unit 210, a content reproduction unit 220, an editing information analysis unit 230, a metadata acquisition request unit 240, a metadata registration request unit 250, and a storage unit 260, and metadata related to content. A computer having a function of assigning The functions of the editing GUI unit 210, content playback unit 220, editing information analysis unit 230, metadata acquisition request unit 240, and metadata registration request unit 250 are realized by software.

  The editing GUI unit 210 is a GUI for editing metadata of material content and completed content. The editing GUI unit 210 allows the operator to input text information as metadata while viewing the content of the completed content. Further, based on the metadata assigned to the completed content, processing for automatically generating and assigning the metadata of the material content constituting the completed content is also performed. Although it is possible to edit the metadata of the material content, as described above, the metadata of the material content is hardly directly input by editing.

  The content playback unit 220 converts the completed content data into a bitmap that can be displayed on the screen of the metadata editing terminal 200, and performs processing for display on the GUI of the editing GUI unit 210. The completed content is stored in the metadata editing terminal 200 in a compressed format such as MPEG (Moving Picture Experts Group). The content playback unit 220 has a function of expanding MPEG data, which is a general technique. The processing of the content playback unit 220 allows the operator to check the content of the video on the same screen when inputting metadata using the editing GUI unit 210.

  The editing information analysis unit 230 performs processing for analyzing EDL which is editing information of the completed content. EDL and techniques for analyzing it are common techniques. The data analyzed and acquired by the editing information analysis unit 230 is used when generating the metadata of the material content based on the metadata of the completed content input by the operator. The contents of this process will be described later.

  The metadata acquisition request unit 240 requests the metadata management server 100 to acquire metadata registered in the metadata management server 100 in a form corresponding to a certain completed content. Since the acquisition request is transferred to the metadata management server 100 via the network 300, the metadata acquisition request unit 240 performs a process of converting it into message data in a format that can be flowed on the network 300. The acquired metadata is transferred to the editing GUI unit 210 and displayed to the operator as the current metadata registration status. The operator can correct the metadata in response to this.

  The metadata registration request unit 250 requests the metadata management server 100 to register the metadata created by the worker using the editing GUI unit 210. Also, processing for requesting and registering metadata of material contents automatically generated by the editing GUI unit 210 to the metadata management server 100 is performed. Since the registration request is transferred to the metadata management server 100 via the network 300, the metadata registration request unit 250 performs processing to convert the request to message data in a format that can be flowed on the network 300.

  The storage unit 260 stores completed content and EDL. The content reproduction unit 220 can read out the completed content stored in the storage unit 260, expand it, and display it. The editing information analysis unit 230 can read and analyze the EDL stored in the storage unit 260.

  With the above-described configuration, the metadata editing terminal 200 is configured so that the operator obtains the registration information of the current metadata of the completed content from the metadata management server 100, reproduces the completed content and refers to the content while referring to the content. Allows editing. Further, based on the completed content metadata and EDL information given by the operator, it is possible to automatically generate the metadata of the material content and register it in the metadata management server 100.

  FIG. 2 is a diagram illustrating an example of the data structure and data of the metadata DB unit 130. As a whole, data is managed separately for each registered content. In the example of FIG. 2, data of material content A, material content B, and completed content C are shown.

  Each content is divided into logically short time intervals, and metadata is given to each content. For example, in the material content A in FIG. 2, the section of 10:10:00 to 10:10:30 and 10:10:30 with the data stored in the columns of the start time 131 and the end time 132 A section of 10 to 11:00 is defined, and metadata is stored in each metadata 133 column. In the column of the metadata 133, a plurality of metadata can be stored for each time interval. In the example of FIG. 2, it is shown that the metadata “Mount Fuji” and the metadata “Scenery” are assigned to the section of 10: 10: 10-10: 10: 30.

  The data stored in the column of accuracy 134 is a number representing the certainty that the corresponding metadata will be correct as representing the target content. In the example of FIG. 2, the probability that the metadata of the section of the material content A from 10:10:00 to 10:10:30 is “Mt. Fuji” is 50%, and the accuracy of “scenery” is 80%. It is shown that.

  The data stored in the columns of the worker 135 and the input date / time 136 indicate the name of the worker who input the corresponding metadata and the input date / time, respectively. The material content B and the completed content C have the same data structure as described above.

  As described above, each metadata stored in the metadata DB unit 130 is given accuracy. This accuracy is calculated by the metadata editing terminal 200, and the metadata DB unit 130 has a role of holding the accuracy in a form associated with the metadata. The value of the accuracy 134 of the metadata DB unit 130 is added / updated together with the content of the metadata 133 in accordance with an instruction from the metadata editing terminal 200. Note that the value of the metadata accuracy 134 for the completed content is 100%.

  FIG. 3 is a diagram showing a screen configuration example of the editing GUI unit 210 on the metadata editing terminal 200. The video display unit 310 is a part that displays the video of the completed content expanded by the content playback unit 220. The play button 320 and the stop button 330 are buttons for controlling video display on the video display unit 310. Techniques for controlling video display by the video display unit 310, the play button 320, the stop button 330, and the like are common. The frame 311 in the video display unit 310 will be described later.

  The timeline display unit 340 is a part that indicates how the material contents constituting the completed content are combined. Information on how completed content is created by combining material content in terms of time and space is defined in EDL. The editing information analysis unit 230 analyzes the EDL, and the editing GUI unit 210 generates a timeline display unit 340 based on the analysis result.

  In the timeline display unit 340, the time axis 341 indicates a virtual time axis. On the time axis 341, the material content A is used from 10:00:00 to 10:11:00 by the timeline 343, and the material content B is 10:10 by the timeline 344. It shows that it is used from 00 seconds to 10:20:00. The timeline bar 342 indicates the time when the video is displayed on the video display unit 310 at the present time. In the example of FIG. 3, an image near 10:10:30 is displayed on the image display unit 310.

  In the timeline display unit 340 in the example of FIG. 3, since the timeline 343 and the timeline 344 overlap at the time indicated by the timeline bar 342, the material content A and the material content B are combined by editing work. It shows that. At that time, both the element of the material content A and the element of the material content B are displayed on the video display unit 310. From the EDL information, it is possible to determine which part of the video uses the material content A and which part uses the material content B. For example, a frame 311 in the video display unit 310 indicates an area where the material content A is used. The technique for analyzing EDL is a technique commonly used in video editing machines.

  The metadata input unit 350 is a part for inputting metadata of completed content and material content. A time interval 354 indicates a short time interval unit corresponding to the upper timeline display unit 340, and indicates that metadata can be input in this unit. Each time interval 354 has an input icon for inputting content metadata, and the input icons 351, 352, and 353 are metadata input icons for the completed content C, material content A, and material content B, respectively. It is shown that.

  The input icon 355 indicates that the focus is focused with a mouse or the like. By double-clicking the input icon 355, a metadata input window 400, which will be described later, pops up, and corresponding content metadata can be input as text.

  The focus of the input icon 355 and the frame 311 are linked. That is, the input icon 355 specifies the target time section and material content. A frame 311 represents, as a frame line, an area where the target material content (material content A in the example of FIG. 3) is used in the completed content in the target time interval. When the focus is moved to the input icon 353 of the material content B, another area (an area where the material content B is used) is surrounded by a frame line in the video display unit 310. When the input icon 351 of the completed content C is focused, no frame line is displayed in the video display unit 310.

  FIG. 4 is a diagram showing a screen configuration example of the metadata input window 400. The metadata input window 400 pops up when an arbitrary input icon 355 of the editing GUI unit 210 of FIG. 3 is double-clicked. The row 410 is data that has already been input, and displays metadata 411, accuracy 412, worker 413, and input date / time 414.

  The menu display unit 430 is an area in which various buttons for performing operations related to input of metadata are arranged. The add button 431 is a button for adding a new input line. The copy button 432 is a button for copying the text of the metadata 411. The paste button 433 is a button for pasting the text of the metadata 411 copied by the copy button 432 to the metadata 411 on another line. As a result, a new input line 420 is added by the add button 431, the metadata 411 of the existing line is copied by the copy button 432, and the metadata 411 of the new input line 420 is added by the paste button 411. You can paste and enter text.

  Using the editing GUI unit 210 shown in FIG. 3 and the metadata input window 400 shown in FIG. 4, the operator can input metadata for the content. The processing flow is as follows. First, the completed content is displayed on the video display unit 310, and the configuration of the material content constituting the completed content is displayed on the timeline display unit 340. While moving the timeline bar 342 and confirming the video at the time indicated by the timeline bar 342, the input icon 355 is double-clicked to open the metadata input window 400 to input metadata.

  The procedure for inputting metadata by the operator differs depending on the contents of the video and the status of the metadata already input. Hereinafter, an input procedure will be described for a case characteristic of the metadata editing system according to the present embodiment.

  FIG. 5 is a diagram illustrating an example in which metadata of material content is automatically generated using EDL information. In FIG. 5, a case where content metadata near 10 hours 10 minutes 30 seconds is input is given as an example. The operator is watching the video of the completed content C on the video display unit 310 and double-clicks the input icon 501 to input metadata of the completed content C.

  In FIG. 5, metadata 511 to 513 and metadata 521 to 523 are records about completed content C, material content A, and material content B in the metadata DB unit 130 of the metadata management server 100 for convenience of explanation. The contents of are simplified and expressed respectively.

  The metadata 511 means that “actor 1” is input as metadata of the completed content C. Here, from the EDL analysis result by the editing information analysis unit 230, the editing GUI unit 210 determines that the completed content C in this time section is from the material content A and the material content B at an area ratio of, for example, 6: 4. Suppose you know that it is being used. Based on this information, the editing GUI unit 210 sets the occupation ratios of the material content A and the material content B in the completed content C to 60% and 40%, respectively, and performs the following automatic conversion on the metadata 511 to 513. Metadata 521 to metadata 523.

  That is, “actor 1” is set as the metadata 522 of the material content A, and the accuracy is 60%, and “actor 1” is set as the metadata 523 of the material content B, and the accuracy is 40%. This result is registered in the metadata management server 100.

  In this embodiment, the occupancy rate of material content is determined using the area ratio of each material content occupying the completed content, but the present invention is not limited to this, and the occupancy rate is determined using other indicators. It can also be determined.

  By the above method, it is possible to automatically add metadata to the material content using the information of the EDL. Accordingly, in the following, when the metadata is added to the completed content in which the material content is reused. This metadata can be used. Further, when searching for material contents, a keyword search using metadata is possible although the accuracy is not 100%.

  FIG. 6 is a diagram illustrating an example in which metadata of material content can be specified by using EDL information. In FIG. 6, a case where content metadata near 10:05:00 is input is taken as an example. Since the operator basically inputs the metadata of the completed content C, the operator double-clicks the input icon 601 and inputs the metadata of the completed content C.

  In FIG. 6, metadata 611 and 612 and metadata 621 and 622 are records for completed content C and material content A in the metadata DB unit 130 of the metadata management server 100, as in the case of FIG. The contents of are simplified and expressed respectively. The metadata 611 means that “actor 1” is input as metadata of the completed content C. Here, from the EDL analysis result by the editing information analysis unit 230, the editing GUI unit 210 knows that the completed content C in this time section consists only of the material content A.

  Based on this information, the editing GUI unit 210 determines that the data “actor 1” in the metadata 611 of the completed content C is the metadata of the material content A, and stores it in the metadata 622 of the material content A. At the same time as copying "Actor 1", the accuracy is 100%. By the above method, the metadata of the material content can be automatically specified and assigned, and the accuracy can be set to 100%.

  FIG. 7 is a diagram illustrating a procedure for inputting metadata of completed content using material content for which metadata has already been input, and an example of increasing the accuracy of the metadata of the material content. In FIG. 7, a case where content metadata near 10:10:30 is input is taken as an example.

  In FIG. 7, metadata 711 to 713 and metadata 721 to 723 are the same as in the case of FIG. 5 described above, in the completed content C, material content A, and material content in the metadata DB unit 130 of the metadata management server 100. It is assumed that the contents of records for B are simplified and expressed respectively.

  The editing GUI unit 210 has a transfer function as an input method for the metadata of the completed content. When the metadata has already been input to the material content, the metadata of the completed content is copied and pasted. Can be entered as Here, it is assumed that when the operator confirms the metadata of the material content A, the content is already described and it is confirmed that the content matches the content of the displayed video. In this case, the operator can input the metadata of the completed content C by copying and pasting the metadata 712 of the material content A into the metadata 711 of the completed content C.

  The content of the record in the metadata DB unit 130 immediately after the input is only the content of the metadata 711 of the completed content C is additionally input by copying and pasting the metadata 712 of the material content A. The editing GUI unit 210 uses the fact that the content of the metadata 712 of the material content A, which has an accuracy of only 60%, is adopted as the metadata 711 of the completed content C, this metadata is stored in the video display unit 310. It is determined that the content of the displayed video matches.

  Based on this information, the editing GUI unit 210 raises the accuracy to 100% by automatically converting the metadata 712 and sets it as metadata 722. At this time, in this embodiment, the accuracy of the metadata 723 of the material content B is kept at 40%, but the accuracy of the metadata 723 may be set to 0% by automatic conversion, for example.

  In order to determine the fact that the content of the metadata 712 of the material content A is adopted as the metadata 711 of the completed content C, for example, as described above, the content of the metadata 712 is changed as described above. It may be determined based on the fact that the copy and pace is set by the operation on the editing GUI unit 210, or a specific button or menu that reflects the contents of the metadata 712 in the metadata 711 is prepared. The determination may be made based on the fact that the contents are reflected by the operation by these.

  By the above method, the operator can use the metadata of the material content to input the metadata of the completed content, and can input it by a simple technique called copy and paste. In addition, the accuracy of the metadata of the material content can be automatically determined to 100%.

  FIG. 8 is a diagram illustrating a procedure for inputting metadata of another time section using metadata of a certain time section of the completed content and an example of increasing the accuracy of the metadata of the material content. In FIG. 8, a case where content metadata near 10:05:00 is input is taken as an example.

  In FIG. 8, metadata 811 to 813, metadata 814 and 815, metadata 821 to 823, and metadata 824 and 825 are the metadata DB portion of the metadata management server 100 as in the case of FIG. It is assumed that the records of the completed content C, the material content A, and the material content B in 130 are simplified and expressed respectively.

  Assume that “actor 1” is input as metadata 811 of the completed content C near 10:10:30 in advance. At this time, as in the case of FIG. 5 described above, as a result of inputting the metadata 811 of the completed content C, “Actor 1” is automatically registered as the metadata 812 of the material content A with an accuracy of 60%. As the metadata 813 for B, “Actor 1” is automatically registered with an accuracy of 40%.

  Thereafter, when the operator inputs the metadata 814 of the completed content C at around 10:05:00, the completed content C metadata 811 at 10:10:30 is transferred by the transfer function of the editing GUI unit 210. Assume that you entered by copying and pasting. The editing GUI unit 210 performs the following processing based on this information.

  From the EDL analysis result by the editing information analysis unit 230, it can be seen that the completed content C is composed only of the material content A at around 10:05:00. Since “Actor 1”, which is the metadata 811 of the completed content C at 10:10:30, is adopted as the metadata 814 of the completed content C at 10:05:00, the above-described FIG. As in the case of, the metadata 815 of the material content A at 10:05:00 is “actor 1”. Accordingly, as in the case of FIG. 6 described above, “actor 1” is automatically registered with the accuracy of 100% as the metadata 825 of the material content A at 10:05:00.

  Further, material content A and material content B, which are metadata constituting the completed content C at 10:10:30, and material content A, which is metadata constituting the completed content C at 10:05:00. Since the material content that overlaps is only the material content A, the data “actor 1” in the metadata 811 of the completed content C at 10:10:30 is given from the display content of the material content A. I understand that there is. Therefore, the accuracy of the metadata 822 of the material content A at 10:10:30 is automatically determined to 100%.

  In the example of FIG. 8, the completed content C is composed of only the material content A around 10:05:00. However, for example, the completed content C is the material around 10:05:00. Even in the case of content A and material content D, since the material content A is the only material content that overlaps in two time intervals, the metadata 823 and 825 of the material content A is “actor 1”. ”Can be automatically determined as 100%.

  Similarly to the case of FIG. 7, the fact that the content of the metadata 811 of the completed content C at 10:10:30 has been adopted as the metadata 814 of the completed content C at 10:05:00 has been edited. In order for the unit 210 to make a determination, for example, as described above, the content may be determined based on the fact that the content of the metadata 811 is copied and copied by an operation in the editing GUI unit 210. It may be determined based on the fact that specific buttons, menus, or the like that reflect the contents of 811 in the metadata 814 are prepared and the contents are reflected by the operations performed by these buttons.

  By the above method, the worker can use the metadata of the completed content in another time interval in order to input the metadata of the completed content in a certain time interval, and inputs it by a simple method called copy and paste. be able to. In addition, when there is only one material content constituting the completed content to which metadata is input, or when there is only one material content overlapping in both time intervals, the metadata of the material content Can be automatically determined to be 100% in both time intervals.

  As described above, in the metadata editing system according to the present embodiment, an operator can input metadata for the created completed content. At this time, the metadata of the material content can be automatically generated based on the metadata attached to the completed content without performing the work of assigning the metadata to the material content constituting the completed content. .

  In this way, metadata can be added to the material content. Therefore, when creating a completed content using the material content as editing material, it is necessary to extract the metadata that is most suitable for reuse from a huge amount of material content. It becomes possible to use keyword search using data. As a result, the optimum material content can be selected and the search time can be shortened, so that the efficiency of content editing can be increased.

  In addition, when the completed content is created based on the material content to which the metadata is added, by analyzing the EDL, it is possible to know which part of the material content is used for the completed content. Data can be automatically assigned as metadata of completed content. As a result, it is possible to save time and effort to add metadata to the completed content, and to further improve work efficiency.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  For example, in FIG. 1 described above, the metadata editing system according to the present embodiment is configured such that the metadata management server 100 and the metadata editing terminal 200 are connected to the network 300. However, the present invention is not limited to such a configuration. For example, the configuration may be such that the metadata management server 100 and the metadata editing terminal 200 are mounted on one computer.

  Also, in the metadata editing system of the present embodiment, the metadata management server 100 has a metadata DB unit 130 as a database for managing metadata, and the function of editing metadata is on the metadata editing terminal 200. However, the present invention is not limited to such a configuration. For example, software that implements the function of a Web server on the metadata management server 100 and edits metadata is executed on the Web server as a Web application. The metadata editing terminal 200 can be configured to use a Web browser for the user interface.

  The present invention can be used for a metadata editing system, a metadata editing program, and a metadata editing method for editing content metadata.
