Abstract

PROBLEM TO BE SOLVED: To display the property of data to make it much easier for a user to use since it is necessary for the user to designate the display of all properties owned by each of metadata schemas in order to view the property owned by different metadata schemas though the property to be displayed in folder unit is designated and displayed in conventional data list display, and since it is necessary to secure a wide screen area in designating the display of all the properties owned by many types of metadata schemas.SOLUTION: When displaying a data group in which one or more properties are defined by type of data in a tabular form, a display device obtains a data group to be displayed, and specifies the type of data from the obtained data group, and displays the property of the data group by giving priority to the property which is common in the data group and the property defined according to the specified type of data.

Description

  The present invention relates to a data display method for displaying a data group having a different metadata schema depending on the type of data.

  Conventionally, when displaying a list of data groups having different metadata schemas depending on the type of data, the following method has been used. For example, it is a method realized by Windows (registered trademark) Explorer of Macrosoft Co., Ltd. In the explorer of the Windows XP (registered trademark) operating system, first, the operator selects the detailed display. After that, the operator selects the property to be displayed for each folder, specifies the width of the property to be displayed, and specifies the display order of the property to be displayed, and the data is displayed. Here, there has been proposed a database system construction method capable of registering all target items with a simplified table structure by registering identification information and contents in a cell (see, for example, Patent Document 1).

Reference numeral 512 denotes a subject property representing a subject in an image that is used only when the data type is an image.

In the present embodiment, a metadata schema including a plurality of properties is defined (defined) as follows according to the type property 502 (data type). That is, a metadata schema whose type property 502 is “document” includes a name property 501, a type property 502, a creation date property 503, an author property 504, a classification property 505, and a keyword property 506.
A metadata schema whose type property 502 is “moving image” includes a name property 501, a type property 502, a shooting date / time property 507, an event property 508, a reproduction time property 509, and a recording standard property 510.
The metadata schema whose type property 502 is “image” includes a name property 501, a type property 502, a shooting date / time property 507, an event property 508, a shooting location property 511, and a subject property 512.
Here, the name property 501 and the type property 502 are properties common to all types of metadata schemas of documents, images, and moving images (hereinafter referred to as “common properties”). Also, the shooting date / time property 507 and the event property 508 are properties common to the metadata schema of the image and moving image types.

In the present embodiment, as shown in FIG. 5, as data whose type of data is a document, first data (data whose name property 501 is “Notice of athletic meet”) and second data (name property) There are two cases in total, including data 501 for “program”.
In addition, as data whose type of data is a moving image, there are a total of four cases of third data, fifth data, seventh data, and tenth data.

The property value of the name property 501 of the eleventh data is “IMG0349.jpg”.
A property holds a value (property value). For example, the first “athletic day notice” data can hold values in the metadata schema type property 502, creation date property 503, creator property 504, classification property 505, and keyword property 506. . However, the first data cannot hold values in the shooting date / time property 507, the event property 508, the playback time property 509, the recording standard property 510, the shooting location property 511, and the subject property 512.

  Reference numeral 323 denotes a specified data type (hereinafter referred to as “specific data type”), which holds any of the property values of the type property 502 included in the target data 322 (see FIG. 3). . The specific data type is determined by the CPU 201 in the process of step S302. The process of step S302 will be described in detail later. In this embodiment, the CPU 201 specifies “document” as the specific data type.

In step S303, the CPU 201 displays a list of data (a list display screen 312 or the like described later). The process of step S303 will be described in detail later.
FIG. 6 is a diagram illustrating an example of the list display screen 312. Reference numeral 601 denotes a folder tree pane that displays a folder hierarchy tree structure, which is basically the same as the folder tree pane 401, but here, the “athletic meet” folder is selected. Reference numeral 610 denotes a folder content pane. The folder content pane 610 is the same area as the folder content pane 402, but here, since the “athletic meet” folder is selected in the folder tree pane 601, the CPU 201 stores the data stored in the “athletic meet” folder. Is displayed.
In the present embodiment, the data displayed in the folder content pane 610 is target data 322, which is 11 pieces of data shown in FIG. Here, the CPU 201 displays property names of a name property 501, a type property 502, a creation date property 503 of a metadata schema whose data type is a document, a creator property 504, a classification property 505, and a keyword property 506. Further, the CPU 201 displays the property value of the target data 322 corresponding to the property name on the first line after the second line of the folder content pane 610.
Reference numeral 602 denotes a compressed display (symbol) that compresses and represents a plurality of properties included in a metadata schema unique to images and moving images other than documents.

A process in which the CPU 201 acquires the target data 322 in the process of step S301 will be described. First, when the CPU 201 detects that a folder has been selected by the operator on the initial screen 311, the CPU 201 performs the process of step S <b> 301.
In step S <b> 301, the CPU 201, which is an example of an acquisition unit, acquires files, folders, and the like stored in the folder selected on the initial screen 311. In the present embodiment, it is assumed that the “Athletic meet” folder is selected in the folder tree pane 401 as an example of the initial screen 311 on the initial screen 311. That is, in step S301, the CPU 201 designates the “athletic meeting” folder for the data management program 321 in order to obtain the files, folders, and the like stored in the “athletic meeting” folder, and the files and folders included in the folder. Get information such as. In step S <b> 301, the CPU 201 (data management program 321) outputs information such as the acquired file and folder as target data 322.

  A process in which the CPU 201 identifies the data type in the process of step S302 will be described. In step S302, the CPU 201, which is an example of the specifying unit, specifies the type of data from the target data 322, and outputs the specified type of data as the specific data type. In the present embodiment, data positioned at the top of the target data 322 shown in FIG. 5 (in this example, data whose name property 501 is “Notice of athletic meet”) is specified target data. Since the property value of the type property 502 of the specific target data (in this example, the data whose name property 501 is “Notice of athletic meet”) is a document, the CPU 201 outputs “document” as the specific data type.

A process in which the CPU 201 displays a list of data in the process of step S303 will be described. In step S303, the CPU 201 extracts a common property (that is, a common property) in each metadata schema included in the target data 322, and further extracts a property held in the metadata schema of the specific target data. In step S <b> 303, the CPU 201, which is an example of a display unit, displays the extracted property on a folder content pane 610, which is an example of the list display screen 312. The CPU 201 displays the property name on the first line of the folder content pane 610. Then, the CPU 201 sets and displays property values corresponding to the respective property names from the target data 322 in the second and subsequent lines.
In step S <b> 303, the CPU 201 displays a symbol representing compression (that is, a compression display 602) for properties that are not displayed as properties of each metadata schema included in the target data 322.
In this embodiment, common properties in the target data 322 are a name property 501 and a type property 502. The metadata schema properties of “document” are a name property 501, a type property 502, a creation date property 503, a creator property 504, a classification property 505, and a keyword property 506. Therefore, duplicate property names (name property 501 and type property 502) displayed in the first line of the folder content pane 610 are collected into a name, type, creation date, creator, classification, and keyword.
Then, the CPU 201 sets a property value corresponding to the property name to be displayed from the target data 322 and displays it. For example, in the second row of the folder content pane 610, “Notice of athletic meet” is set and displayed under the name. Also, “Document” is set under the type, and “2006/9/10” is set under the creation date, and these are displayed. In addition, “XX elementary school” is set under the creator, “school” is set under the classification, and “athletic day, news” is set under the keyword, and these are displayed. Similarly, the CPU 201 sets and displays the property value corresponding to the property name from the target data 322 in the third and subsequent lines of the folder content pane 610.

Here, the compression display 602 represents compression (symbol) of a property that is not displayed as a property of each metadata schema included in the target data 322. In other words, the compressed display 602 is displayed as a symbol representing the shooting date and time, event, playback time, recording standard, shooting location, and subject that are not displayed in the first line.
Note that the method of acquiring data stored in the selected folder is realized by executing the data management program 321, but may be realized using a file system, a database, a Web service, or the like.
Further, in the present embodiment, the data type specified in step S302 is positioned at the highest level, and the name property 501 that is the highest level data shown in FIG. However, the present invention is not limited to this. For example, the data displayed at the top of the folder content pane 610 may be the top data (specific target data).

As described above, when displaying a list of the properties of different metadata schemas, the CPU 201 preferentially displays the properties common to the plurality of metadata schemas and the properties possessed by the metadata schema of a specific data type. According to this configuration, even in a list display of a relatively narrow screen area, the property of the target data can be displayed without performing screen scrolling as much as possible. In addition, for example, the CPU 201 gives priority to displaying the properties of the metadata schema of the data type that the operator is interested in and the properties shared by the metadata schema of the plurality of data types from the list-displayed data. May be. According to this configuration, a wide screen area is not necessarily required, and the properties of data of interest can be displayed.
Further, according to the configuration according to the present embodiment, the operator does not need to specify properties to be displayed in folder units. Further, according to the configuration according to the present embodiment, since all the properties of many types of metadata schemas are rarely displayed, a large screen area is required because the number of properties to be displayed is very large. This can reduce the frequency of occurrences.

<Second Embodiment>
The configuration of the second embodiment is basically the same as the configuration of the first embodiment. In the first embodiment, in specifying the data type in the process of step S302, the data at the top of the target data 322, that is, the data whose name property 501 property value is “Notice of athletic meet” is specified target data. It was. Therefore, in the first embodiment, the CPU 201 outputs “document” as the specific data type.
In the second embodiment, in specifying the data type in the process of step S302, the CPU 201 sets the type having the largest number in the target data 322 as the specific data type. In the target data 322, there are two data types of document data, four data types of moving image data, and five data types of image data. Therefore, in specifying the data type in the second embodiment, the CPU 201 outputs the most frequently used “image” as the specific data type. Thereby, the process regarding the target data 322 of the second embodiment is as follows.

Here, as shown in FIG. 5, the common properties are a name property 501 and a type property 502, which are the same as those in the first embodiment. In the present embodiment, the specific data type is “image”. The metadata schema properties of “image” are a name property 501, a type property 502, a shooting date / time property 507, an event property 508, a shooting location property 511, and a subject property 512. Accordingly, duplicate property names (name property 501 and type property 502) are collected in the first line of the folder content pane 810, which is an example of the list display screen 312, and the name, type, shooting date and time, event , Shooting location and subject.
That is, the CPU 201 sets and displays a property value corresponding to the property name to be displayed from the target data 322 (see FIG. 7). For example, “IMG0345.jpg” is set and displayed under the name in the fifth line of the folder content pane 810. Also, “Image” is set under the type, “2006/10/10 9:25:34” is set under the shooting date and time, and these are displayed. “Athletic meet” is set under the event, “XX elementary school” is set under the shooting location, “Hanako” is set under the subject, and these are displayed. Note that the CPU 201 similarly sets and displays the property value corresponding to the property name from the target data 322 in the other rows of the folder content pane 810.

The compressed display 801 and the compressed display 802 indicate that a property that is not displayed as a property of each metadata schema included in the target data 322 is compressed. More specifically, the compressed display 801 includes a creation date, a creator, a classification, and a property unique to the metadata schema whose data type is not displayed in the first line of the folder content pane 810. It is displayed as a symbol representing the compressed keyword. The compressed display 802 is displayed as a symbol representing a compressed reproduction time and recording standard, which are unique properties in the metadata schema of the “moving image” data type that is not displayed in the first line of the folder content pane 810. .
Here, in specifying the data type in the processing of step S302 in the present embodiment, the CPU 201 specifies the most common type as an image from the whole. However, the present invention is not limited to this. For example, the CPU 201 may identify the most common type of data displayed in the folder content pane 810 as the data type.

<Third Embodiment>
The configuration of the third embodiment is basically the same as the configuration of the first embodiment and the configuration of the second embodiment. In the second embodiment, in the specification of the data type in the process of step S302, the type having the largest number among the target data 322 is set as the data type. Therefore, in the second embodiment, the CPU 201 outputs “image” as the specific data type.
In the third embodiment, in specifying the data type in the process of step S302, the CPU 201 sets the data type selected from the target data 322 as the specific data type. Note that the initial screen 311 in the third embodiment is, for example, the screen shown in FIG. 7 which is an example of the list display screen of the second embodiment.
In the present embodiment, it is assumed that the CPU 201 detects that the third data is selected from the folder content pane 710 and sets the third data as specific target data. That is, in the specification of the data type in the process of step S302, the CPU 201 sets the data whose name property 501 as the third data is “Kakekko” as the target data. Then, the CPU 201 outputs “moving image” which is the type of data as a specific data type. Thereby, the process regarding the target data 322 of the third embodiment is as follows.

As shown in FIG. 5, the common properties are a name property 501 and a type property 502, which are the same as those in the first embodiment and the second embodiment. The “moving image” properties include a name property 501, a type property 502, a shooting date / time property 507, an event property 508, a playback time property 509, and a recording standard property 510. Accordingly, duplicate property names (name property 501 and type property 502) are collected in the first line of the folder content pane 710, which is an example of the list display screen 312, and the name, type, shooting date and time, event , Playback time, and recording standard.
That is, the CPU 201 sets and displays a property value corresponding to the property name to be displayed from the target data 322 (see FIG. 8). For example, in the fourth line of the folder content pane 710, “Kakekko” is set under the name, “Movie” is set under the type, and “2006/10/10 9:24: 22 ”is set and these are displayed. “Athletic meet” is set under the event, “45 seconds” is set under the playback time, and these are displayed. Also, “HDV1080i” is set and displayed under the recording standard. Note that the CPU 201 similarly sets the property value corresponding to the property name from the target data 322 and displays the other rows in the folder content pane 710 as well.

A compressed display 801 and a compressed display 702 illustrated in FIG. 8 indicate that properties that are not displayed as properties of each metadata schema included in the target data 322 are compressed.
More specifically, the compressed display 801 includes a creation date, a creator, a classification, and a property unique to the metadata schema whose data type is not displayed in the first line of the folder content pane 710. It is displayed as a symbol representing the compressed keyword. The compressed display 702 is displayed as a symbol representing the shooting location and subject, which are unique properties in the metadata schema whose data type is “image”, which is not displayed in the first row of the folder content pane 710, in a compressed manner.
In the present embodiment, by selecting only the fourth row from the folder content pane 710, only the data on the fourth row is set as the identification target data. However, the present invention is not limited to this. For example, when a plurality of rows are selected at a time, there are a plurality of identification target data, and when the data types are different, the CPU 201 may identify a plurality of specific data types. For example, when the fourth and fifth rows shown in FIG. 8 are selected, the CPU 201 outputs “image” and “moving image” as the specific data types. In this case, the compressed display 702 is not the compressed display, and “shooting place” and “subject” are displayed. Further, if the folder content pane 710 does not fit on one screen due to an increase in the properties to be displayed, it may be configured to scroll horizontally.
According to the configuration described above, the operator does not need to specify to display all the properties of each metadata schema in order to see the properties of the different metadata schemas.

The acquisition of the target data 322 is not limited to opening a normal folder storing folders, files, and the like. For example, the CPU 201 may prioritize and display properties in the same way for opening a search folder and searching results in addition to opening a normal folder. In addition, the target data 322 has been described by taking a document, an image, and a moving image file as examples, but is not limited thereto. For example, when there is a folder as the target data 322, the CPU 201 may preferentially display the metadata schema property of the folder.
In the list display screen 312, properties that are not displayed are compressed and displayed, but the present invention is not limited to this. For example, the CPU 201 does not perform a compressed display (display related to compression itself) like the folder content pane 910 illustrated in FIG.
Further, the CPU 201 displays all the common properties and the specified data type properties, but the present invention is not limited to this. For example, a configuration in which display presence / absence in the list display is designated for each property of the metadata schema may be adopted. Moreover, although the common property is used as the common property for all types of the target data 322, the present invention is not limited to this. For example, a property common to a plurality of types in the target data may be set as a common property.

<Other embodiments>
Each process of the embodiment described above can also be realized by executing software (program) acquired via a network or various storage media by a processing device (CPU, processor) such as a personal computer.

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to such specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
