Persistent ID: Provide optional timer job to periodically verify resolution of all dataset persistent ids, handle and doi.

Eleni mentioned this came up as part of the DataCite membership application: what steps do we take as a repo to maintain or verify continued operation and resolution of persistent ids.

At this time we monitor whether the handle service is running but we have some tickets open to make the registration process more robust to handle times of remote service outages for both handle and dois.

What we are missing is the post registration piece where properly registered ids (or otherwise) are checked to confirm ids resolve properly and if not are either resolved automatically or notification is sent to an admin for attention.

Start by locating the existing persistent ID registration and monitoring paths for Handle and DOI services. Review how remote-service outages are handled, then determine where a periodic verification job and admin notification or automatic recovery would fit. Done means registered dataset IDs are checked for resolution and failures receive the agreed response.
