>
> The current behavior - when we delete an entity *f1*, all tags associate to *f1* which
got propagated
> to downstream entities are removed – *PII* tag propagated to *process1* and *t1* is
removed
> *Proposed Change*
> _*Soft Delete:*_
> When entity *f1* is deleted, retain the propagated classification edges, so the downstream
entities
> – *process1* and *t1* continue to have *PII* classification associated to them
> _*Hard Delete:*_
> In cases of hard delete, the source entity (*f1*) is deleted from atlas, but its classification
vertex
> (*PII*) continue to exist and will continue propagating to *process1* and *t1*.
