PROBLEM TO BE SOLVED: To provide an abstract syntax data storage device which uses a memory area with high efficiency and processes values at high speed, and an MIB which is high in the use efficiency of the memory area. SOLUTION: An abstract syntax data conversion means 0102 receives transferring syntax data, discriminates whether the data are to be stored in the device or not, converts the data into the internal data to be used in the device if they need to be stored and further outputs an abstract syntax key which corresponds to the data. An abstract syntax data storage means 0103 stores transfer syntax data which are converted by the abstract syntax data conversion means 0102 into the internal data. An abstract syntax definition storing means 0104 stores a table which contains abstract syntax definitions and an integer values (index) corresponding to the definition as entries. An MO class definition storing means 0803 stores a zero ID given to each class definition for discriminating the MO class and a table which entries an integer values (index) corresponds to the ID and defines what attributes the MO instances which belong to respective MO classes have.
