                                   Table I.1 – Use case – Initiating provenance information

                    Title                            Initiating provenance information record
             Description        A BDSP requests data from a data provider (DP), and gets the data. At this time, BDSP stores
                                data as it is or modifies the original data to fit for their own database. During this process,
                                BDSP start is to record provenance information which includes the origin of data described in
                                metadata, functional processes which were applied to modify data, and stores them to
                                distributed database.
