Attribute definitions:

id	:	An identifier of the <thing> for the purposes of record management within a system.
record_copy_created	:	The date and time when this copy of the record was created in the current system. This attribute shall have a value only when the current system is not the originating system.
record_created	:	The date and time on which this record was first created in its originating system.
record_creator	:	The person, organisation or system that first created this record in the originating system.
record_logically_deleted	:	The date and time that this record was logically deleted.
why_deleted	:	The reason why the record was logically deleted. NOTE: Logical deletion means that whilst the record is still available in the system as a matter of historical record, it is no longer considered a valid statement. That is to say it is considered that it was never true.
