VERIFICATION METHOD, INFORMATION PROCESSING APPARATUS, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM FOR STORING VERIFICATION PROGRAM

摘要

A verification method includes: acquiring, in response to XBRL data, data of an optional title from the XBRL data as target data to be verified; specifying, with reference to definition information of the XBRL data, attribute values assigned to data of the same title as the target data; and verifying validity of the target data by using an algorithm that determines that the target data is valid when the specified attribute values are associated with or not associated with the target data, and determines that the target data is not valid when attribute values other than the specified attribute values are associated with the target data, wherein the verifying is configured to determine that the target data is not valid when the specified attribute values include attribute values of a predetermined type, and none of the attribute values of the predetermined type is associated with the target data.
