Method, apparatus, and program for supporting creation and management of metadata for correcting problem in dynamic web application

An apparatus for supporting creation and management of metadata for correcting a problem in a dynamic web application, the apparatus comprising:

• a metadata creation section configured to create metadata M1, in response to correction of a problem in a web application by a corrector, the metadata M1 including operation information indicating an operation for correcting the problem and application conditions of the operation information, and the application conditions including semantic block information including a location at which the problem has occurred in a Web page and a global variable group and cookie information that identify the state of the web application in which the problem has occurred;
• an operation-log storage section configured to store an operation log on the web application by the corrector;
• a similar-block search section configured to calculate metadata, for each of one or more blocks B0 that match the block information of the metadata M1 of blocks in the Web page that has shifted during a correction operation, with reference to the operation log read from the operation-log storage section, the metadata including a global variable group and cookie information that identify the state of the web application that has output the Web page including the blocks B0;
• and
• a metadata generalizing section configured to convert each of the global variable groups and the cookie information acquired for the metadata M1 and the individual blocks B0 to a key-value pair structure, extracting a common portion therefrom, and updating the global variable groups and the cookie information of the metadata M1 by using the extracted common portion.

A computer-readable program product for supporting creation and management of metadata for correcting a problem in a dynamic web application, the program product comprising a tangible storage device readable by a computer for causing the computer to execute a method comprising:

• creating metadata M1 in response to correction of a problem in a web application by a corrector, the metadata M1 including operation information indicating an operation for correcting the problem and application conditions of the operation information, and the application conditions including semantic block information including a location at which the problem has occurred in a Web page and a global variable group and cookie information that identify the state of the web application in which the problem has occurred;
• calculating metadata, for each of one or more blocks B0 that match the block information of the metadata M1 of blocks in the Web page that has shifted during a correction operation, with reference to an operation log on the web application by the corrector, the metadata including a global variable group and cookie information that identify the state of the web application that has output the Web page including the blocks B0;
• and
• converting each of the global variable groups and the cookie information acquired for the metadata M1 and the individual blocks B0 to a key-value pair structure, extracting a common portion therefrom, and updating the global variable groups and the cookie information of the metadata M1 by using the extracted common portion.
