Figure 7-5 – Provenance operations according to data state change

Operations to manage provenance information are:
– record provenance unit (see clause 7.3.1);
– keep provenance unit (see clause 7.3.2);

– combine provenance unit (see clause 7.3.2);
– delete provenance unit (see clause 7.3.2);
– retrieve provenance information (see clause 7.3.3).
7.3.1 Provenance information in case of storing and updating data

Figure 7-6 shows provenance units recording according to the data storing and updating.
– provenance unit recording: When Data 1 are stored, BDSP records Provenance unit 1. Data 1 is
updated to Data 2 and 3, BDSP records Provenance unit 2 and Provenance unit 3 sequentially.

7.3.2 provenance information in case of deleting data

In case of deleting data, the provenance management system provided by BDSP acts in the three ways
described in clauses 7.3.2.1 to 7.3.2.3.
7.3.2.1 Keep provenance unit

When data are deleted from storage, the provenance management system keeps its provenance unit to
support traceability of data within process steps. Figure 7-7 shows an example where provenance units are
kept after the deletion of data.
