Would like a REST API which will retrieve a Rosetta IE METS record

You can retrieve the METS by adding 'dps_func=mets' to the delivery URL -

https://digital.slq.qld.gov.au/delivery/DeliveryManagerServlet?change_lng=en&dps_pid=IE305955&dps_func=mets

however, the delivery manager will not deliver the METS information if there is are access rights preventing the delivery of the digital asset

so would like a way to retrieve the METS data regardless of the access rights on the asset
