Scheme for systemically registering meta-data with respect to various types of data

A meta-data registration device, comprising:

• a detection unit configured to detect at least one of a format and a data name extension of registering data to be registered into a Web server that registers and manages data and meta-data for data;
• a selection unit configured to select one procedure corresponding to the MIME format or the extension detected by the detection unit, from a plurality of procedures each provided in correspondence to at least one of a MIME format and an extension and stored in advance, each procedure having a-program code for generating the meta-data for data according to a corresponding MIME format or extension, each procedure containing information for specifying formats of the meta-data to be generated according to the corresponding MIME format or extension, and each procedure being designed to generate names and values of the meta-data in formats specified by said information;
• and
• an output unit configured to output the meta-data for the registering data generated by executing the program code of said one procedure selected by the selection unit, to the Web server.

A Web server device, comprising:

• a request processing unit configured to receive and process a registration request for registering data to be registered into the Web server device;
• a management unit configured to register the registering data according to the registration request and manage data and meta-data for data;
• a detection unit configured to detect at least one of a MIME format and a data name extension of the registering data;
• a selection unit configured to select one procedure corresponding to the MIME format or the extension detected by the detection unit, from a plurality of procedures each provided in correspondence to at least one of a MIME format and an extension and stored in advance, each procedure having a program code for generating the meta-data for data according to a corresponding MIME format or extension, each procedure containing information for specifying formats of the meta-data to be generated according to the corresponding MIME format or extension, and each procedure being designed to generate names and values of the meta-data in formats specified by said information;
• a generation unit configured to generate the meta-data for the registering data by executing the program code of said one procedure selected by the selection unit;
• and
• a registration unit configured to register the meta-data generated by the generation unit into the management unit.

A computer usable medium having computer readable program code embodied therein for causing a computer to function as a meta-data registration device, the computer readable program codes include:

• a first computer readable program code for causing said computer to detect at least one of a MIME format and a data name extension of registering data to be registered into a Web server that registers and manages data and meta-data for data;
• a second computer readable program code for causing said computer to select one procedure corresponding to the MIME format or the extension detected by the first computer readable program code, from a plurality of procedures each provided in correspondence to at least one of a MIME format and an extension and stored in advance, each procedure having a program code for generating the meta-data for data according to a corresponding MIME format or extension, each procedure containing information for specifying formats of the meta-data to be generated according to the corresponding MIME format or extension, and each procedure being designed to generate names and values of the meta-data in formats specified by said information;
• and
• a third computer readable program code for causing said computer to output the meta-data for the registering data generated by executing the program code of said one procedure selected by the second computer readable program code, to the Web server.

A computer usable medium having computer readable program codes embodied therein for causing a computer to function as a Web server device, the computer readable program codes include:

• a first computer readable program code for causing said computer to receive and process a registration request for registering data to be registered into the Web server device;
• a second computer readable program code for causing said computer to register the registering data according to the registration request and manage data and meta-data for data;
• a third computer readable program code for causing said computer to detect at least one of a MIME format and a data name extension of the registering data;
• a fourth computer readable program code for causing said computer to select one procedure corresponding to the MIME format or the extension detected by the third computer readable program code, from a plurality of procedures each provided in correspondence to at least one of a MIME format and an extension and stored in advance, each procedure having a program code for generating the meta-data for data according to a corresponding MIME format or extension each procedure containing information for specifying formats of the meta-data to be generated according to the corresponding MIME format or extension, and each procedure being designed to generate names and values of the meta-data in formats specified by said information;
• a fifth computer readable program code for causing said computer to generate the meta data for the registering data by executing the program code of said one procedure selected by the fourth computer readable program code;
• and
• a sixth computer readable program code for causing said computer to register the meta-data generated by the fifth computer readable program code into a management unit in the Web server.

A meta-data registration method, comprising the steps of:

• detecting at least one of a MIME format and a data name extension of registering data to be registered into a Web server that registers and manages data and meta-data for data on a name space having tree-like hierarchical structure;
• selecting one procedure corresponding to the MIME format or the extension detected by the detecting step, from a plurality of procedures each provided in correspondence to at least one of a MIME format and an extension and stored in advance, each procedure having a program code for generating the meta-data for data according to a corresponding MIME format or extension, each procedure containing information for specifying formats of the meta-data to be generated according to the corresponding MIME format or extension, and each procedure being designed to generate names and values of the meta-data in formats specified by said information;
• generating the meta-data for the registering data by executing the program code of said one procedure selected by the selecting step;
• and
• registering the meta-data generated by the generating step in relation to the registering data into the Web server.
