            7.3.2.2    Combine provenance units

            When data are deleted from storage, the provenance management system combines the data's provenance
            unit with the forward nearest provenance unit within process steps. This is described in the example given in
            Figure 7-8.





















                              Figure 7-8 – Combine provenance units to support data traceability
            NOTE – In Figure 7-8, the forward nearest provenance unit of provenance unit 2 is provenance unit 3.

            7.3.2.3      Delete provenance unit
            When data are deleted from storage, and if the data instance is placed at the right end node of process steps,
            the provenance management system deletes the provenance unit together with the data. This is illustrated
            in the example given in Figure 7-9.
