"""Mint record identifiers.
This is a minter specific for records.
With the help of
:class:`invenio_pidstore.providers.recordid.RecordIdProvider`, it creates
the PID instance with `rec` as predefined `object_type`.
Procedure followed: (we will use `control_number` as value of
`PIDSTORE_RECID_FIELD` for the simplicity of the documentation.)
#. If a `control_number` field is already there, a `AssertionError`
exception is raised.
#. The provider is initialized with the help of
:class:`invenio_pidstore.providers.recordid.RecordIdProvider`.
It's called with default value 'rec' for `object_type` and `record_uuid`
variable for `object_uuid`.
#. The new `id_value` is stored inside `data` as `control_number` field.
:param record_uuid: The record UUID.
:param data: The record metadata.
:returns: A fresh `invenio_pidstore.models.PersistentIdentifier` instance.
