Table I.2 – Use case – Updating data and managing provenance information

Title Updating data and managing provenance information in big data system

Description <Adding provenance information based on the change of data source status>
– A BDSP uses external data source regularly. When DP:DS update the status of data (e.g.,
schema version upgrade, change of responsible person's information), BDSP manages the
change of source information, and checks existing data is still available or not;
– BDSP searches the existing provenance information and adds the changing information;
<Managing provenance information caused by deleting or preserving data from local data
storage>
– BDSP deletes or retires the stored data for storage efficiency or the other management
issues. BDSP monitors the provenance information and decides to delete it or not.
