Description

Working state of our Script to generate beacon files of some identifier based on the beacon draft (https://gbv.github.io/beaconspec/beacon.html) (our implementation in dspace 5 was mentioned in some earlier PR #218)
Script for generating files according to the beacon standard (see https://gbv.github.io/beaconspec/beacon.html). It get all (visibile) entities of some identifier and prints them into one process result file or optionally dumps them in the handler log.
