+.. note::  In Blazar reservations are encapsulated in leases, whereby one lease can have several reservations (i.e. reserved resources) with the same start and end dates.
+
+.. note::  In the reservation system (e.g. Blazar) each lease/reservation has additional implementation level attributes not listed in the mapping tables in this document, e.g. lease_id, status, status reason, action, …, and which are not included in reservation requests.
