TERMINAL APPARATUS,SERVER,CONTENT DATA STORAGE METHOD,AND PROGRAM FOR EXECUTING THE METHOD

摘要

A user can easily search for a content data such as recipe data. When a personal computer (103) receives recipe data from a server (101) via a communication network (102), the data is stored in a memory card (104). Here, a recipe hierarchical information (142) representing a recipe data classification hierarchy based on a search key is updated so as to include the new recipe data by referencing entire hierarchical information (133) representing the search key hierarchical relationship in the entire recipe.
