Patent ID: 8762380

Claim:
An information processing apparatus that performs processing for editing information on contents, comprising: an acquisition means for acquiring an attribute data classification information element, in which attribute data elements indicating predetermined attributes of the contents are correlated with category data elements indicating categories for classifying the attributes of the contents; a selection means for selecting a predetermined attribute data element from the attribute data elements included in the attribute data classification information element acquired by the acquisition means; a correlation means for newly correlating the selected attribute data element selected by the selection means with a second category data element other than a first category data element to which the selected attribute data element is already correlated with in the attribute data classification information element acquired by the acquisition means, in response to a user's instruction, by editing the attribute data classification information element to add the second category data element to the attribute data classification information element without altering the attribute data elements of the contents, wherein the attribute data classification information element includes a table that correlates the attribute data elements with the category data elements, and the editing the attribute data classification information element includes adding the second category data element to the table, such that the selected attribute data element correlates with both the first and second category data elements in the table; a reproduction means for reproducing a first content of the contents, the first content having a first attribute data element; and a display means for displaying: a first link map for only the first content, the first link map including a first attribute data classification information element that includes the first attribute data element, by drawing a line directly connecting the first attribute data element and the first attribute data classification information element, and one or more second attribute data elements, other than the first attribute data element, that are respectively included in the first attribute data classification information element, by drawing lines directly connecting the first attribute data classification information elements to the one or more second attribute data elements.
