Abstract
A structured data management system capable of easily changing the definition of a logical structure and controlling semantics described in data adapted to the defined structure as intended by persons who have defined the logical structure. A contents model defines an internal structure of a contents description. The contents description describes data to be managed according to the contents model. An operation description is coupled to the contents model and manipulates data in the contents description depending on the structure of the data in the contents description. The operation description functions to define semantics of each element of the structure defined by the contents model. An operation description executing unit executes the operation description coupled to the contents model. A structure managing unit verifies and manages the structure of the contents description according to the contents model.
