Abstract
An information management system for modifying action of system in accordance with previously set policy with reference to metadata and/or log data accompanying data to be managed makes efficient information lifecycle management by reducing the grading of the data to be managed and increasing the expressive power of the definable policy while suppressing increase of the amount of necessary metadata and/or log data. The ontology for defining the relation between terms referred in business level is introduced and analyzed together with the policy, so that the range necessary for acquisition of information can be clearly decided to thereby reduce time and labor required for modification of setting and the operation management cost and optimize necessary resources.
