Abstract

According to this invention, upon managing a plurality of data by individually appending meta data used to search for the data, an input sheet that describes predetermined candidates of meta data is prepared, the user selects meta data from the candidates of meta data, and the selected meta data is saved in association with the data. Upon making a search, a data search is conducted using meta data, and after the data found by search are partially provided to the user, the user selects desired data. In this way, everyone can easily and efficiently append information for a search to data to be managed.

accepting a user'"'"'s selection of a meta data to be appended to the selected managed data from the provided group of candidates of the meta data; and

appending the selected meta data to the selected managed data by saving an association between the selected meta data and the selected managed data.

14. A method according to claim 13, further comprising the steps of:

accepting an input of a search condition used to search for the managed data;

searching for the managed data associated with the search condition on the basis of the input search condition and the meta data; and

partially providing contents of the managed data found by the search performed in said searching step.

15. A computer-executable program stored on a computer-readable medium, for executing a data management method for managing data by appending meta data for a data search to managed data, said program comprising:
