To provide a data management apparatus, a method therefor, and a program in which data are efficiently managed by reducing editing of additional information in real data.
A write/read part 205 generates first data as template data of the additional information and writes the first data onto a memory card 206. Besides, the write/read part 205 reads an additional information data part out of second data composed of a real data part and its additional information data part written onto the memory card 206. A data composing part 203 compares the read additional information data part with the first data, generates a new additional information data part with respect to the real data part contained in the second data based upon the compared result, and generates third data composed of the real data part and the new additional information data. Then, the third data are managed in a data saving part 203a.
