Information processing method and apparatus and recording medium

An information processing apparatus, comprising:

• a computer-readable storage medium;
• means for constructing a program using a plurality of components,
• wherein each component of said plurality of components includes version information showing a self version and a version compatible information table showing a self past version embedded in said each component,
• wherein the version compatible information table comprises a start version, an end version and a flag, the flag indicating a version range which designates a plurality of different versions satisfying requirements for compatibility with said component, based on the start version and the end version, each of the plurality of different versions within the version range indicating that the component is updated for different times, and
• wherein said version information and said version compatible information table is updated each time said each component is updated;
• means for selecting, when another component sends a request to load said each component, a component of a latest version from a plurality components which has a same name but different version;
• and
• means for determining compatibility between said selected component's version and a version requested by said another component by loading and using said version information and said version compatible information table included in said selected component.

A computer-readable storage medium for storing a computer program, for assembling a program, the program comprising executable instruction that cause a computer to:

• construct a program using a plurality of components,
• wherein each component of said plurality of components includes version information showing a self version and a version compatible information table showing a self past version embedded in said each component,
• wherein the version compatible information table comprises a start version, an end version and a flag, the flag indicating a version range which designates a plurality of different versions satisfying requirements for compatibility with said component, based on the start version and the end version, each of the plurality of different versions within the version range indicating that the component is updated for different times, and
• wherein said version information and said version compatible information table is updated each time said each component is updated;
• select, when another component sends a request to load said each component, a component of a latest version from a plurality components which has a same name but different version;
• and
• determine compatibility between said selected component's version and a version requested by said another component by loading and using said version information and said version compatible information table included in said selected component.
