Data processing apparatus, method, program, and storage medium for setting identification information based on metadata, and advantageously displaying print data

A data processing method employed by a data processing apparatus that sets identification information for identifying each of a plurality of contents based on metadata added to each of the contents, the method comprising the steps of:

• acquiring title information of each of the contents, the title information concerning a title of the content and being included in the metadata;
• a processor comparing the title information of each of the contents to extract a part of the title information that is common to all of the contents;
• setting, in at least one memory, the identification information of each of the contents based on the part of the title information that is not the part of the title information common to all of the contents;
• separating the title information of each of the contents into a plurality of pieces of unit information;
• and
• comparing the pieces of unit information of the title information of each of the contents to extract unit information common to different ones of the contents, the common unit information being extracted to form a visually recognizable hierarchy.

A non-transitory computer-readable medium storing a program for causing a computer to perform a process of setting identification information for identifying each of a plurality of contents based on metadata added to each of the contents, the program causing the computer to function as:

• title information acquisition means for acquiring title information of each of the contents, the title information concerning a title of the content and being included in the metadata;
• information extraction means for comparing the title information of each of the contents to extract a part of the title information that is common to all of the contents;
• identification information setting means for setting the identification information of each of the contents based on the part of the title information that is not the part of the title information common to all of the contents;
• and
• title information separating means for separating the title information of each of the contents into a plurality of pieces of unit information,
• wherein said information extraction means compares the pieces of unit information of the title information of each of the contents to extract unit information common to different ones of the contents, the common unit information being extracted to form a visually recognizable hierarchy.

A data processing apparatus that generates print data for printing, on a storage medium, information for identifying a plurality of contents stored in the storage medium, the apparatus comprising:

• title acquisition means for acquiring a character sequence denoting a title of each of the contents stored in the storage medium;
• title information separating means for separating the title of each of the contents into a plurality of pieces of unit information;
• information extraction means for comparing the pieces of unit information of the title of each of the contents to extract unit information common to different ones of the contents, the common unit information being extracted to form a visually recognizable hierarchy;
• and
• print data generation means for generating the print data, wherein
• a part of the character sequence denoting the title of each of the contents, the part being common to all of the contents, is printed in a first area on the storage medium, and
• the part of the character sequence, denoting the title of each of the contents other than the part of the character sequence common to all of the contents, is printed in a second area on the storage medium.

A data processing apparatus that sets identification information for identifying each of a plurality of contents based on metadata added to each of the contents, the apparatus comprising:

• a title information acquisition section configured to acquire title information of each of the contents, the title information concerning a title of the content and being included in the metadata;
• an information extraction section configured to compare the title information of each of the contents to extract a part of the title information that is common to all of the contents;
• an identification information setting section configured to set the identification information of each of the contents based on the other part of the title information than the part of the title information that is common to all of the contents;
• and
• a title information separating section configured to separate the title information of each of the contents into a plurality of pieces of unit information,
• wherein said information extraction section compares the pieces of unit information of the title information of each of the contents to extract unit information common to different ones of the contents, the common unit information being extracted to form a visually recognizable hierarchy.
