Use cases of big data provenance
(This appendix does not form an integral part of this Recommendation.)

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.
