Behavior

Authorization

A Delete MUST come from the instance hosting the entity it deletes, which is the domain in the deleted Reference. A receiver MUST reject any other Delete.

A receiver MUST ignore a Delete whose deleted_type differs from the type it has stored for the entity, and delete nothing.

Which of its users may delete what is up to that instance. With no author, the Delete comes from the instance that signed it.

Fetching Deleted Entities

An instance SHOULD answer a request for an entity it has deleted with 410 Gone if it remembers the entity, and 404 Not Found otherwise.

A 404 Not Found can also mean that the requesting instance may not fetch the entity. So an instance MUST NOT delete its copy of an entity because of a 404. Only a Delete entity or a 410 Gone means the entity is gone.

Whether to keep a record of an entity after deleting it is up to the receiver.
