Title (Goal)Support for configurable OAI deletion policies
Primary ActorRepository Manager, Harvester

Story (A paragraph or two describing what happens)

OAI specification describes three tracking levels for record deletion: no, persistent and transient. While 

Status
titleno
and
Status
titletransient
do not provide any useful information about deleted records,
Status
titlepersistent
explicitly states the deletion of a previously existing record and thus helps to keep a harvesters database update to date. The repository should allow to configure the deletion behavior according to OAI specification.
