To define if an SRS record is deleted, accept the leader in the MARC record "as is". MARC Leader 05 - Record status will identify what is marked for deletion (Record status equals "d", "s" or "x") and what is not. Also "deleted" field can be used for this purpose (see json example below).
"updatedDate" field can be used to identify the date of deletion.
Just instance records stored in SRS are in the scope of this story.
- Deleted records are defined by MARC Leader 05 in ("d", "s", "x") or json field "deleted"=true: if either of these checks is true, the record should be considered as deleted.
- "updatedDate" field is returned as record deletion date.
- Provide the result time of a request before the additional filter was applied and after
