B2SHARE seems to store ePIC PIDs with domain parti 'http://hdl.handle.net/' into database

Currently B2SHARE REST API is returning full URL to a ePIC PID. E.g.:
ePIC_PID : "http://hdl.handle.net/11304/9bda3890-eb08-40db-83e2-147d255b5ed5"

This is fine but, it seems that the domain part 'http://hdl.handle.net/' is directly stored in database.
This should not be the case, since the domain part might change in the future.
Database migration should be done and domain should be removed from ePIC PIDs stored in database.
